The Bilski Decision Is In: Buh-Bye [Most] Business Methods Patents - As text - Updated
Thursday, October 30 2008 @ 03:27 PM EDT

Pop some champagne! The Appeals Court decision [PDF] is in on Bilski: I'm still reading it, but on first quick reading, one thing is clear: it's a win! Eligible patent matter just got smaller. Here's a snip from the opening:
We affirm the decision of the Board because we conclude that Applicants' claims are not directed to patent-eligible subject matter, and in doing so, we clarify the standards applicable in determining whether a claimed method constitutes a statutory "process" under § 101.
This was an appeal against a rejection of a business methods patent, and the appeals court has now agreed with the rejection. At issue was whether an abstract idea could be eligible for patent protection. The court says no.

Buh-bye business methods patents! [Most of them.]

I want to thank Red Hat most particularly for its wonderful amicus brief that it filed in this case, for representing the community's interests and getting certain issues on the court's radar. However, the court in footnote 23 does not go as far as one might have hoped, at least not in this case:

Therefore, although invited to do so by several amici, we decline to adopt a broad exclusion over software or any other such category of subject matter beyond the exclusion of claims drawn to fundamental principles set forth by the Supreme Court. See, e.g., Br. of Amicus Curiae End Software Patents; Br. of Amicus Curiae Red Hat, Inc. at 4-7. We also note that the process claim at issue in this appeal is not, in any event, a software claim. Thus, the facts here would be largely unhelpful in illuminating the distinction between those software claims that are patent-eligible and those that are not not.

And which is which? They just say that they don't know what the words "technological arts" and "technology" mean, as they are "both ambiguous and ever-changing". So they "continue to rely on the machine-or-transformation test as articulated by the Supreme Court." You'll find all that discussed on page 25. For now, this court is saying there has to be a machine in the process, not just ideas in your head. They leave to future cases refinements on software patents. No doubt there will be some. Here's the paragraph on that:
Nevertheless, we agree that future developments in technology and the sciences may present difficult challenges to the machine-or-transformation test, just as the widespread use of computers and the advent of the Internet has begun to challenge it in the past decade. Thus, we recognize that the Supreme Court may ultimately decide to alter or perhaps even set aside this test to accommodate emerging technologies. And we certainly do not rule out the possibility that this court may in the future refine or augment the test or how it is applied. At present, however, and certainly for the present case, we see no need for such a departure and reaffirm that the machine-or- transformation test, properly applied, is the governing test for determining patent eligibility of a process under § 101.

There were numerous amici briefs filed, of course, and you can find most of them here on PatentlyO, and many thanks are due. You can see how many amici briefs there were in the opening, where it lists them all, 4 pages' worth. Some were on the side of business methods patents, of course. My, it's been a bad month for hedge funds.

The 132-page PDF includes a concurring opinion, beginning on page 37 of the PDF, and three dissents, either believing the court is going too far, the dissent by Justice Newman beginning on page 57 and one by Justice Rader beginning on page 123, or thinking it didn't go far enough, by Justice Mayer beginning on page 98. You'll particularly enjoy the dissent by Judge Mayer. Here's one taste:

The patent system is intended to protect and promote advances in science and technology, not ideas about how to structure commercial transactions....

Affording patent protection to business methods lacks constitutional and statutory support, serves to hinder rather than promote innovation and usurps that which rightfully belongs in the public domain....

State Street has launched a legal tsunami....Patents granted in the wake of State Street have ranged from the somewhat ridiculous to the truly absurd.

He cites a few. Here's my personal favorite: a method of training janitors to dust and vacuum using video displays. A close second is the patent granted for method of selling expert advice. The concurring opinion ends like this:
In short, the history of §101 fully supports the majority's holding that Bilski's claim does not recite patentable subject matter. Our decision does not reflect "legislative" work, but rather careful and respectful adherence to the Congressional purpose.
That's on page 56 of the PDF.

Here's the Wall St.Journal:

But in today's ruling, the court largely disavowed the highly controversial 1998 decision, State Street Bank v. Signature Financial Group. That case had granted protection to a system for managing mutual fund accounts. The State Street decision was widely cheered by the financial-services and software industries, among others. But ever since its issuance, the State Street case has been a lightning rod among patent practitioners, with detractors largely arguing that it led to a glut of weak patents.

"This is a pretty clear disavowal of State Street," said Daniel Crowe, a patent litigator at Bryan Cave LLP in St. Louis who was not involved in the case. "It's a ruling against the financial services industry." Mr. Crowe said he did not know what would happen to the business-method patents validated within the last 10 years. "That's definitely an open question."

So, the fact that the court did not 100 percent disavow all software patents doesn't mean it didn't just trim them plenty. It did. Here's how, from a later Wall St. Journal article:
Randy Lipsitz, a patent specialist at Kramer Levin in New York says the ruling is likely to hit certain industries, namely insurance, banking, accounting and software, particularly hard. “You’re going to see fewer applications from these industries,” he says.

And what about the likelihood of the case rising to the Supremes? The experts seem torn. Lipsitz says that given the case’s importance — he calls the case one of the most significant ever to be decided by the Federal Circuit — and the High Court’s recent fondness for patent cases, he suspects it will go up. But Bradley Wright, a partner at Banner & Witcoff in Washington, thinks the Federal Circuit has tailored the decision to avoid reversal from above, and therefore any need for the Supremes to take it. “The Federal Circuit went out of its way to mention Supreme Court precedent,” he says. “I’d be surprised if cert is granted on this.”

Ah! Fewer patent applications from the software industry. That has a lovely ring. And what about earlier patents granted, and patents threats based upon them? Ah! The analysis begins.

Others are noticing details I missed on first reading, namely that there may be ways to still get some business methods patents, according to this article in BusinessWeek:

Kappos said IBM was “very pleased” with the court’s decision. “It doesn’t spell the complete demise of business-method patents,” he says, “But without question it points to a major downsizing.” In a conference call to discuss the ruling, Accenture representatives acknowledged that the court had not embraced the broad view of patentability that Accenture had pushed for, but emphasized that there was still room to protect business strategies.

While rulings over the years have used various tests to determine if a process qualifies for patenting, the Federal Circuit said the sole analysis should be the “machine-or-transformation” test – which requires showing that the claimed invention is either tied to a particular machine or that it transforms an “article” (such as a substance or data). At the same time, the majority opinion, joined by 9 of the 12 justices ruling in the case – acknowledged that “the widespread use of computers and the advent of the Internet” had begun to challenge the usefulness of such a test. The justices invited the U.S. Supreme Court to develop a new test for determining the kinds of inventions that should be eligible for patent protection, one that might better “accommodate emerging technologies.”

But the court dodged what for many is a crucial question: Whether simply employing a computer itself is enough to earn patent eligibility.

CNET has a reaction from Jason Schultz, who authored one of the amicus briefs:
"We've seen a rise in the number of lawsuits against tech companies in the IT area specifically. Many are very questionable patents, and the patent office is overwhelmed," said Jason Schultz, acting director of The Samuelson Law, Technology & Public Policy Clinic at UC Berkeley. "It will reduce the number of patent applications which are filed in the IT space--especially by these questionable entities or companies trying to patent trivial things."
And here's VentureBeat:
The ruling clarified what types of patents the court found eligible: “(1) it is tied to a particular machine or apparatus, or (2) it transforms a particular article into a different state or thing.” Ten years ago, the same court had ruled that a “useful, concrete, and tangible result” also signified that a concept could be patented. The result, as researchers later showed, was a 3000 percent increase in the number of business method patents between 1995 and 2001.
We can reasonable expect that to reverse direction now.

PatentlyO's Take:

Here's PatentlyO on the decision, explaining what might still pass:

Some Business Methods and Software Are Still In:

Still, the court made clear that business methods and Software will still be patentable – if they meet the machine-or-transformation test.

We rejected [a categorical] exclusion in State Street, noting that the so-called "business method exception" was unlawful and that business method claims (and indeed all process claims) are "subject to the same legal requirements for patentability as applied to any other process or method." We reaffirm this conclusion.

[A]lthough invited to do so by several amici, we [also] decline to adopt a broad exclusion over software or any other such category of subject matter beyond the exclusion of claims drawn to fundamental principles set forth by the Supreme Court

To be clear, the machine-or-transformation test is not a physicality test – i.e., a claim can still be patentable even if it does not recite sufficient "physical steps." Here, the court spelled out the specific issue in mind: a claimed process where every step may be performed entirely in the human mind. In that situation, the machine-or-transformation test would lead to unpatentability. "Of course, a claimed process wherein all of the process steps may be performed entirely in the human mind is obviously not tied to any machine and does not transform any article into a different state or thing. As a result, it would not be patent-eligible under § 101."

On the flip-side, "a claim that recites 'physical steps' but neither recites a particular machine or apparatus, nor transforms any article into a different state or thing, is not drawn to patent-eligible subject matter."

He also explains what is a transformation, so take a look if you really want to understand that fully. But here's the snip he highlights from the court's ruling:
As the court noted later in the opinion, the transformed articles must be "physical objects or substances [or] representative of physical objects or substances."

The Bilski claims themselves were not seen as transforming an article:

Purported transformations or manipulations simply of public or private legal obligations or relationships, business risks, or other such abstractions cannot meet the test because they are not physical objects or substances, and they are not representative of physical objects or substances. Applicants' process at most incorporates only such ineligible transformations. . . . As discussed earlier, the process as claimed encompasses the exchange of only options, which are simply legal rights to purchase some commodity at a given price in a given time period. The claim only refers to "transactions" involving the exchange of these legal rights at a "fixed rate corresponding to a risk position." Thus, claim 1 does not involve the transformation of any physical object or substance, or an electronic signal representative of any physical object or substance.
The principle behind the test is to prevent a patentee from obtaining claims that preempt the use of fundamental principles.
He also points out that the decision seems to ignore two rulings by the US PTO Board of Patent Appeals, Ex parte Langemyr [PDF] and Ex parte Wasynczuk [PDF], which already held that "A general purpose computer is not a particular machine, and thus innovative software processes are unpatentable if they are tied only to a general purpose computer," an issue this court seems to view as still to be decided by future cases. And hopefully that is just what will happen next.

What About Microsoft?

Gene Quinn is writing [PJ: Note that as of June 28, 2010, that link is dead, and he has blocked Internet Archive, but I saved a local copy, and this is what he wrote.] that it's his opinion that this ruling means the end of software patents as we know them and that State Street in effect is overturned:

The Federal Circuit has overruled State Street and software patents are no longer available as they have come to be available over the last 10 to 15 years. If you do not agree with these points then you obviously have not read the decision and I suggest that you read the decision before you tell me that I am wrong. I have thick skin, but reality is quite important to me.

First, you can point to whatever you want in the opinion where the Court said "we are not overruling State Street," but that doesn't change the reality that the Court has done just that. You know the old question about a dog's leg, right? If I were to tell you to assume that the dog's tail is a leg, how many legs would the dog have? The answer is 4, because regardless of whether you call the tail a leg or not the truth is that the tail is a tail and it is never going to be a leg regardless of your desire to call it one. So, the Federal Circuit can say all they want that State Street has not been overruled, but the reality is that it has been overruled. The Federal Circuit just didn't do us the honor of being honest and straight forward with us.

The entire point of Judge Rich's decision in the State Street case was to recognize that a process can be patent worthy even if there is no physical transformation. He was 100% correct and this Court has undercut the decision in its entirety. When the Court says that clearly strikes at the heart of State Street:

  • The useful, concrete and tangible result inquiry "is insufficient to determine whether a claim is patent-eligible under § 101."
  • "[W]e also conclude that the "useful, concrete and tangible result" inquiry is inadequate and reaffirm that the machine-or-transformation test outlined by the Supreme Court is the proper test to apply. "
  • Footnote 19: "[T]hose portions of our opinions in State Street and AT&T relying solely on a "useful, concrete and tangible result" analysis should no longer be relied on."
If the "useful, concrete and tangible result" inquiry is insufficient and inadequate to determine the existence of patentable subject matter under 101 then State Street has quite clearly been overruled, evicerated, disregarded or whatever you would like to call it. For crying out loud the majority even said in footnote 19 that the "useful, concrete and tangible result" inquiry can no longer be relied upon! What else do they have to say in order to get folks to understand that State Street has been overruled?
Of course, he's upset. He's a patent lawyer, and so to him this is a "stupid" decision, and he points out that he's upset because "much of the Microsoft patent portfolio has gone up in smoke" and he doesn't see how it can protect its software now. (What? Copyright, trademark, trade secret, faux interoperability, standards capture, and dirty tricks are not enough? They worked for Microsoft when it was building its business, prior to State Street.) As his partner, John White said to him today, "Microsoft doesn't make machines." He may have forgotten that Microsoft submitted an amicus brief [PDF] with Dell asking that patents not be issued unless tied to a computer and resulting in a transformation. By my reading, Microsoft got what it asked for on that. Don't forget that Microsoft also gets sued over stupid patents and has an interest in some rationality to the process. The court went further than it asked for, in tossing out the useful, concrete and tangible language, and that's what Quinn is disturbed about, and probably Microsoft is too. I agree with Quinn for sure on one thing: it's a good day for Open Source.

Here's the take by the Practicing Law Institute. They also see it as meaning that software patents are more or less over. "In order to protect what was formerly known as patentable software we will have to go back to claiming a machine that provides certain functionality." And no doubt they'll be scrambling to do exactly that.

The dissenting opinion by Mayer also predicts workarounds will result from the decision:

The majority's proposed "machine-or-transformation test" for patentability will do little to stem the growth of patents on non-technological methods and ideas. Quite simply, in the context of business method patent applications, the majority's proposed standard can be too easily circumvented.... Through clever draftsmanship, nearly every process claim can be rewritten to include a physical transformation.
This is on page 118 of the PDF. It's true, and they'll try, but the patent world has just changed, and that has made all the difference.

Quinn has written a followup also, and here's one paragraph:

I have been asked in the comments to my other posts what patents I thought would be useless now thanks to the Bilski decision. After doing a quick analysis I was quite surprised. There are easily thousands of patents that now have claims that are invalid, but many of these patents will remain because they have been written properly and have tied at least certain aspects of the invention to a system or apparatus. It seems clear to me, however, that the broadest, strongest claims are now lost. The method and computer code claims, which are now lost, were the truly significant claims providing the most protection.
He provides a short and selective list of patents he believes are now invalid, due to this decision, mainly patents from IBM's portfolio. He elaborates on his misery about this ruling making software patents hard to obtain on IP Watchdog also.

Here's the decision as a quick text version to help you follow along, minus the dissents, which I hope to provide later. For some reason, it's the custom to only list the last names or initials of the judges, but Law.com provides some of them in Mike Scarcella's coverage:

Paul Michel, Chief Judge
Dissenting: Pauline Newman
Randall Rader
H. Robert Mayer
You can find all the justices' official bios here.

Finally, Lada & Parry has the clearest explanation of the ruling and what it likely means here.

[Update Feb. 3, 2009: The law firm of Finnegan LLP is announced today it is asking the US Supreme Court to review this decision. No word yet on whether or not the court will do so.]

__________________________

DECIDED: October 30, 2008

__________________________

Before MICHEL, Chief Judge, NEWMAN, MAYER, LOURIE, RADER, SCHALL, BRYSON, GAJARSA, LINN, DYK, PROST, and MOORE, Circuit Judges.

Opinion for the court filed by Chief Judge MICHEL, in which Circuit Judges LOURIE, SCHALL, BRYSON, GAJARSA, LINN, DYK, PROST, and MOORE join. Concurring opinion filed by Circuit Judge DYK, in which Circuit Judge LINN joins. Dissenting opinion filed by Circuit Judge NEWMAN. Dissenting opinion filed by Circuit Judge MAYER. Dissenting opinion filed by Circuit Judge RADER.

MICHEL, Chief Judge.

Bernard L. Bilski and Rand A. Warsaw (collectively, "Applicants") appeal from the final decision of the Board of Patent Appeals and Interferences ("Board") sustaining the rejection of all eleven claims of their U.S. Patent Application Serial No. 08/833,892 ("892 application"). See Ex parte Bilski, No. 2002-2257, 2006 WL 5738364 (B.P.A.I. Sept. 26, 2006) ("Board Decision"). Specifically, Applicants argue that the examiner erroneously rejected the claims as not directed to patent-eligible subject matter under 35 U.S.C. § 101, and that the Board erred in upholding that rejection. The appeal was originally argued before a panel of the court on October 1, 2007. Prior to disposition by

the panel, however, we sua sponte ordered en banc review. Oral argument before the en banc court was held on May 8, 2008. We affirm the decision of the Board because we conclude that Applicants' claims are not directed to patent-eligible subject matter, and in doing so, we clarify the standards applicable in determining whether a claimed method constitutes a statutory "process" under § 101.

I.

Applicants filed their patent application on April 10, 1997. The application contains eleven claims, which Applicants argue together here. Claim 1 reads:

A method for managing the consumption risk costs of a commodity sold by a commodity provider at a fixed price comprising the steps of:
(a) initiating a series of transactions between said commodity provider and consumers of said commodity wherein said consumers purchase said commodity at a fixed rate based upon historical averages, said fixed rate corresponding to a risk position of said consumer;

(b) identifying market participants for said commodity having a counter- risk position to said consumers; and

(c) initiating a series of transactions between said commodity provider and said market participants at a second fixed rate such that said series of market participant transactions balances the risk position of said series of consumer transactions

'892 application cl.1. In essence, the claim is for a method of hedging risk in the field of commodities trading. For example, coal power plants (i.e., the "consumers") purchase coal to produce electricity and are averse to the risk of a spike in demand for coal since such a spike would increase the price and their costs. Conversely, coal mining companies (i.e., the "market participants") are averse to the risk of a sudden drop in demand for coal since such a drop would reduce their sales and depress prices. The claimed method envisions an intermediary, the "commodity provider," that sells coal to

the power plants at a fixed price, thus isolating the power plants from the possibility of a spike in demand increasing the price of coal above the fixed price. The same provider buys coal from mining companies at a second fixed price, thereby isolating the mining companies from the possibility that a drop in demand would lower prices below that fixed price. And the provider has thus hedged its risk; if demand and prices skyrocket, it has sold coal at a disadvantageous price but has bought coal at an advantageous price, and vice versa if demand and prices fall. Importantly, however, the claim is not limited to transactions involving actual commodities, and the application discloses that the recited transactions may simply involve options, i.e., rights to purchase or sell the commodity at a particular price within a particular timeframe. See J.A. at 86-87.

The examiner ultimately rejected claims 1-11 under 35 U.S.C. § 101, stating: "[r]egarding . . . claims 1-11, the invention is not implemented on a specific apparatus and merely manipulates [an] abstract idea and solves a purely mathematical problem without any limitation to a practical application, therefore, the invention is not directed to the technological arts." See Board Decision , slip op. at 3. The examiner noted that Applicants had admitted their claims are not limited to operation on a computer, and he concluded that they were not limited by any specific apparatus. See id. at 4.

On appeal, the Board held that the examiner erred to the extent he relied on a "technological arts" test because the case law does not support such a test. Id. at 41-42. Further, the Board held that the requirement of a specific apparatus was also erroneous because a claim that does not recite a specific apparatus may still be directed to patent-eligible subject matter "if there is a transformation of physical subject matter from one state to another." Id. at 42. Elaborating further, the Board stated:

3

"'mixing' two elements or compounds to produce a chemical substance or mixture is clearly a statutory transformation although no apparatus is claimed to perform the step and although the step could be performed manually." Id. But the Board concluded that Applicants' claims do not involve any patent-eligible transformation, holding that transformation of "non-physical financial risks and legal liabilities of the commodity provider, the consumer, and the market participants" is not patent-eligible subject matter. Id. at 43. The Board also held that Applicants' claims "preempt[] any and every possible way of performing the steps of the [claimed process], by human or by any kind of machine or by any combination thereof," and thus concluded that they only claim an abstract idea ineligible for patent protection. Id. at 46-47. Finally, the Board held that Applicants' process as claimed did not produce a "useful, concrete and tangible result," and for this reason as well was not drawn to patent-eligible subject matter. Id. at 49-50.

Applicants timely appealed to this court under 35 U.S.C. § 141. We have jurisdiction under 28 U.S.C. § 1295(a)(4)(A).

II.

Whether a claim is drawn to patent-eligible subject matter under § 101 is a threshold inquiry, and any claim of an application failing the requirements of § 101 must be rejected even if it meets all of the other legal requirements of patentability. In re Comiskey , 499 F.3d 1365, 1371 (Fed. Cir. 2007)1 (quoting Parker v. Flook , 437 U.S.

4

584, 593 (1978)); In re Bergy , 596 F.2d 952, 960 (CCPA 1979), vacated as moot sub nom. Diamond v. Chakrabarty , 444 U.S. 1028 (1980). Whether a claim is drawn to patent-eligible subject matter under § 101 is an issue of law that we review de novo. Comiskey , 499 F.3d at 1373; AT&T Corp. v. Excel Commc'ns, Inc ., 172 F.3d 1352, 1355 (Fed. Cir. 1998). Although claim construction, which we also review de novo, is an important first step in a § 101 analysis, see State St. Bank & Trust Co. v. Signature Fin. Group , 149 F.3d 1368, 1370 (Fed. Cir. 1998) (noting that whether a claim is invalid under § 101 "is a matter of both claim construction and statutory construction"), there is no claim construction dispute in this appeal. We review issues of statutory interpretation such as this one de novo as well. Id.

A.

As this appeal turns on whether Applicants' invention as claimed meets the requirements set forth in § 101, we begin with the words of the statute:

Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title.
35 U.S.C. § 101. The statute thus recites four categories of patent-eligible subject matter: processes, machines, manufactures, and compositions of matter. It is undisputed that Applicants' claims are not directed to a machine, manufacture, or composition of matter.2 Thus, the issue before us involves what the term "process" in

5

§ 101 means, and how to determine whether a given claim--and Applicants' claim 1 in particular--is a "new and useful process."3

As several amici have argued, the term "process" is ordinarily broad in meaning, at least in general lay usage. In 1952, at the time Congress amended § 101 to include "process,"4 the ordinary meaning of the term was: "[a] procedure . . . [a] series of actions, motions, or operations definitely conducing to an end, whether voluntary or involuntary." WEBSTER'S NEW INTERNATIONAL DICTIONARY OF THE ENGLISH LANGUAGE 1972 (2d ed. 1952). There can be no dispute that Applicants' claim would meet this definition of "process." But the Supreme Court has held that the meaning of "process" as used in § 101 is narrower than its ordinary meaning. See Flook, 437 U.S. at 588-89 ("The holding [in Benson] forecloses a purely literal reading of § 101."). Specifically, the Court has held that a claim is not a patent-eligible "process" if it claims "laws of nature, natural phenomena, [or] abstract ideas." Diamond v. Diehr, 450 U.S. 175, 185 (1981) (citing Flook, 437 U.S. at 589, and Gottschalk v. Benson, 409 U.S. 63, 67 (1972)). Such

6

fundamental principles5 are "part of the storehouse of knowledge of all men . . . free to all men and reserved exclusively to none." Funk Bros. Seed Co. v. Kalo Inoculant Co., 333 U.S. 127, 130 (1948); see also Le Roy v. Tatham, 55 U.S. (14 How.) 156, 175 (1852) ("A principle, in the abstract, is a fundamental truth; an original cause; a motive; these cannot be patented, as no one can claim in either of them an exclusive right."). "Phenomena of nature, though just discovered, mental processes, and abstract intellectual concepts are not patentable, as they are the basic tools of scientific and technological work." Benson, 409 U.S. at 67; see also Comiskey, 499 F.3d at 1378-79 (holding that "mental processes," "processes of human thinking," and "systems that depend for their operation on human intelligence alone" are not patent-eligible subject matter under Benson).

The true issue before us then is whether Applicants are seeking to claim a fundamental principle (such as an abstract idea) or a mental process. And the underlying legal question thus presented is what test or set of criteria governs the determination by the Patent and Trademark Office ("PTO") or courts as to whether a claim to a process is patentable under § 101 or, conversely, is drawn to unpatentable subject matter because it claims only a fundamental principle.

The Supreme Court last addressed this issue in 1981 in Diehr, which concerned a patent application seeking to claim a process for producing cured synthetic rubber products. 450 U.S. at 177-79. The claimed process took temperature readings during cure and used a mathematical algorithm, the Arrhenius equation, to calculate the time when curing would be complete. Id. Noting that a mathematical algorithm alone is

7

unpatentable because mathematical relationships are akin to a law of nature, the Court nevertheless held that the claimed process was patent-eligible subject matter, stating:
[The inventors] do not seek to patent a mathematical formula. Instead, they seek patent protection for a process of curing synthetic rubber. Their process admittedly employs a well-known mathematical equation, but they do not seek to pre-empt the use of that equation. Rather, they seek only to foreclose from others the use of that equation in conjunction with all of the other steps in their claimed process.
Id. at 187 (emphasis added).6 The Court declared that while a claim drawn to a fundamental principle is unpatentable, "an application of a law of nature or mathematical formula to a known structure or process may well be deserving of patent protection." Id. (emphasis in original); see also Mackay Radio & Tel. Co. v. Radio Corp. of Am., 306 U.S. 86, 94 (1939) ("While a scientific truth, or the mathematical expression of it, is not a patentable invention, a novel and useful structure created with the aid of knowledge of scientific truth may be.").

The Court in Diehr thus drew a distinction between those claims that "seek to pre-empt the use of" a fundamental principle, on the one hand, and claims that seek only to foreclose others from using a particular "application" of that fundamental principle, on the other. 450 U.S. at 187. Patents, by definition, grant the power to exclude others from practicing that which the patent claims. Diehr can be understood to suggest that whether a claim is drawn only to a fundamental principle is essentially an inquiry into the scope of that exclusion; i.e., whether the effect of allowing the claim

8

would be to allow the patentee to pre-empt substantially all uses of that fundamental principle. If so, the claim is not drawn to patent-eligible subject matter.

In Diehr, the Court held that the claims at issue did not pre-empt all uses of the Arrhenius equation but rather claimed only "a process for curing rubber . . . which incorporates in it a more efficient solution of the equation." 450 U.S. at 188. The process as claimed included several specific steps to control the curing of rubber more precisely: "These include installing rubber in a press, closing the mold, constantly determining the temperature of the mold, constantly recalculating the appropriate cure time through the use of the formula and a digital computer, and automatically opening the press at the proper time." Id. at 187. Thus, one would still be able to use the Arrhenius equation in any process not involving curing rubber, and more importantly, even in any process to cure rubber that did not include performing "all of the other steps in their claimed process." See id.; see also Tilghman v. Proctor, 102 U.S. 707, 729 (1880) (holding patentable a process of breaking down fat molecules into fatty acids and glycerine in water specifically requiring both high heat and high pressure since other processes, known or as yet unknown, using the reaction of water and fat molecules were not claimed).

In contrast to Diehr, the earlier Benson case presented the Court with claims drawn to a process of converting data in binary-coded decimal ("BCD") format to pure binary format via an algorithm programmed onto a digital computer. Benson, 409 U.S. at 65. The Court held the claims to be drawn to unpatentable subject matter:

It is conceded that one may not patent an idea. But in practical effect that would be the result if the formula for converting BCD numerals to pure binary numerals were patented in this case. The mathematical formula involved here has no substantial practical application except in connection

9

with a digital computer, which means that if the judgment below is affirmed, the patent would wholly pre-empt the mathematical formula and in practical effect would be a patent on the algorithm itself.
Id. at 71-72 (emphasis added). Because the algorithm had no uses other than those that would be covered by the claims (i.e., any conversion of BCD to pure binary on a digital computer), the claims pre-empted all uses of the algorithm and thus they were effectively drawn to the algorithm itself. See also O'Reilly v. Morse, 56 U.S. (15 How.) 62, 113 (1853) (holding ineligible a claim pre-empting all uses of electromagnetism to print characters at a distance).

The question before us then is whether Applicants' claim recites a fundamental principle and, if so, whether it would pre-empt substantially all uses of that fundamental principle if allowed. Unfortunately, this inquiry is hardly straightforward. How does one determine whether a given claim would pre-empt all uses of a fundamental principle? Analogizing to the facts of Diehr or Benson is of limited usefulness because the more challenging process claims of the twenty-first century are seldom so clearly limited in scope as the highly specific, plainly corporeal industrial manufacturing process of Diehr; nor are they typically as broadly claimed or purely abstract and mathematical as the algorithm of Benson.

The Supreme Court, however, has enunciated a definitive test to determine whether a process claim is tailored narrowly enough to encompass only a particular application of a fundamental principle rather than to pre-empt the principle itself. A claimed process is surely patent-eligible under § 101 if: (1) it is tied to a particular machine or apparatus, or (2) it transforms a particular article into a different state or thing. See Benson, 409 U.S. at 70 ("Transformation and reduction of an article 'to a

10

different state or thing' is the clue to the patentability of a process claim that does not include particular machines."); Diehr, 450 U.S. at 192 (holding that use of mathematical formula in process "transforming or reducing an article to a different state or thing" constitutes patent-eligible subject matter); see also Flook, 437 U.S. at 589 n. 9 ("An argument can be made [that the Supreme] Court has only recognized a process as within the statutory definition when it either was tied to a particular apparatus or operated to change materials to a 'different state or thing'"); Cochrane v. Deener, 94 U.S. 780, 788 (1876) ("A process is . . . an act, or a series of acts, performed upon the subject-matter to be transformed and reduced to a different state or thing.").7 A claimed process involving a fundamental principle that uses a particular machine or apparatus would not pre-empt uses of the principle that do not also use the specified machine or apparatus in the manner claimed. And a claimed process that transforms a particular article to a specified different state or thing by applying a fundamental principle would not pre-empt the use of the principle to transform any other article, to transform the same article but in a manner not covered by the claim, or to do anything other than transform the specified article.

The process claimed in Diehr, for example, clearly met both criteria. The process operated on a computerized rubber curing apparatus and transformed raw, uncured rubber into molded, cured rubber products. Diehr, 450 U.S. at 184, 187. The claim at issue in Flook, in contrast, was directed to using a particular mathematical formula to calculate an "alarm limit"--a value that would indicate an abnormal condition during an

11

unspecified chemical reaction. 437 U.S. at 586. The Court rejected the claim as drawn to the formula itself because the claim did not include any limitations specifying "how to select the appropriate margin of safety, the weighting factor, or any of the other variables . . . the chemical processes at work, the [mechanism for] monitoring of process variables, or the means of setting off an alarm or adjusting an alarm system." See id. at 586, 595. The claim thus was not limited to any particular chemical (or other) transformation; nor was it tied to any specific machine or apparatus for any of its process steps, such as the selection or monitoring of variables or the setting off or adjusting of the alarm. 8 See id.

A canvas of earlier Supreme Court cases reveals that the results of those decisions were also consistent with the machine-or-transformation test later articulated in Benson and reaffirmed in Diehr. See Tilghman, 102 U.S. at 729 (particular process of transforming fats into constituent compounds held patentable); Cochrane, 94 U.S. at 785-88 (process transforming grain meal into purified flour held patentable); Morse, 56 U.S. (15 How.) at 113 (process of using electromagnetism to print characters at a distance that was not transformative or tied to any particular apparatus held unpatentable). Interestingly, Benson presents a difficult case under its own test in that the claimed process operated on a machine, a digital computer, but was still held to be

12

ineligible subject matter.9 However, in Benson, the limitations tying the process to a computer were not actually limiting because the fundamental principle at issue, a particular algorithm, had no utility other than operating on a digital computer. Benson, 409 U.S. at 71-72. Thus, the claim's tie to a digital computer did not reduce the pre-emptive footprint of the claim since all uses of the algorithm were still covered by the claim.

B.

Applicants and several amici10 have argued that the Supreme Court did not intend the machine-or-transformation test to be the sole test governing § 101 analyses. As already noted, however, the Court explicitly stated in Benson that "[t]ransformation and reduction of an article 'to a different state or thing' is the clue to the patentability of a process claim that does not include particular machines."11 409 U.S. at 70 (emphasis added). And the Court itself later noted in Flook that at least so far it had "only

13

recognized a process as within the statutory definition when it either was tied to a particular apparatus or operated to change materials to a 'different state or thing.'" 437 U.S. at 589 n.9. Finally, the Court in Diehr once again applied the machine-or-transformation test in its most recent decision regarding the patentability of processes under § 101. 450 U.S. at 184.

We recognize, however, that the Court was initially equivocal in first putting forward this test in Benson. As the Applicants and several amici point out, the Court there stated:

It is argued that a process patent must either be tied to a particular machine or apparatus or must operate to change articles or materials to a 'different state or thing.' We do not hold that no process patent could ever qualify if it did not meet the requirements of our prior precedents.
Benson, 409 U.S. at 71. In Flook, the Court took note that this statement had been made in Benson but merely stated: "As in Benson, we assume that a valid process patent may issue even if it does not meet [the machine-or-transformation test]." 437 U.S. at 589 n. 9 (emphasis added). And this caveat was not repeated in Diehr when the Court reaffirmed the machine-or-transformation test. See Diehr, 450 U.S. at 184 (quoting Benson, 409 U.S. at 70) ("Transformation and reduction of an article 'to a different state or thing' is the clue to the patentability of a process claim that does not include particular machines."). Therefore, we believe our reliance on the Supreme Court's machine-or-transformation test as the applicable test for § 101 analyses of process claims is sound.

Nevertheless, we agree that future developments in technology and the sciences may present difficult challenges to the machine-or-transformation test, just as the widespread use of computers and the advent of the Internet has begun to challenge it in

14

the past decade. Thus, we recognize that the Supreme Court may ultimately decide to alter or perhaps even set aside this test to accommodate emerging technologies. And we certainly do not rule out the possibility that this court may in the future refine or augment the test or how it is applied. At present, however, and certainly for the present case, we see no need for such a departure and reaffirm that the machine-or- transformation test, properly applied, is the governing test for determining patent eligibility of a process under § 101. 12

C.

As a corollary, the Diehr Court also held that mere field-of-use limitations are generally insufficient to render an otherwise ineligible process claim patent-eligible. See 450 U.S. at 191-92 (noting that ineligibility under § 101 "cannot be circumvented by attempting to limit the use of the formula to a particular technological environment"). We recognize that tension may be seen between this consideration and the Court's overall goal of preventing the wholesale pre-emption of fundamental principles. Why not permit patentees to avoid overbroad pre-emption by limiting claim scope to particular fields of use? This tension is resolved, however, by recalling the purpose behind the Supreme Court's discussion of pre-emption, namely that pre-emption is merely an indication that a claim seeks to cover a fundamental principle itself rather

15

than only a specific application of that principle. See id. at 187; Benson, 409 U.S. at 71-72. Pre-emption of all uses of a fundamental principle in all fields and pre-emption of all uses of the principle in only one field both indicate that the claim is not limited to a particular application of the principle. See Diehr, 450 U.S. at 193 n.14 ("A mathematical formula in the abstract is nonstatutory subject matter regardless of whether the patent is intended to cover all uses of the formula or only limited uses.") (emphasis added). In contrast, a claim that is tied to a particular machine or brings about a particular transformation of a particular article does not pre-empt all uses of a fundamental principle in any field but rather is limited to a particular use, a specific application. Therefore, it is not drawn to the principle in the abstract.

The Diehr Court also reaffirmed a second corollary to the machine-or-transformation test by stating that "insignificant postsolution activity will not transform an unpatentable principle into a patentable process." Id. at 191-92; see also Flook, 437 U.S. at 590 ("The notion that post-solution activity, no matter how conventional or obvious in itself, can transform an unpatentable principle into a patentable process exalts form over substance."). The Court in Flook reasoned:

A competent draftsman could attach some form of post-solution activity to almost any mathematical formula; the Pythagorean theorem would not have been patentable, or partially patentable, because a patent application contained a final step indicating that the formula, when solved, could be usefully applied to existing surveying techniques.
437 U.S. at 590.13 Therefore, even if a claim recites a specific machine or a particular transformation of a specific article, the recited machine or transformation must not

16

constitute mere "insignificant postsolution activity." 14

D.

We discern two other important aspects of the Supreme Court's § 101 jurisprudence. First, the Court has held that whether a claimed process is novel or non-obvious is irrelevant to the § 101 analysis. Diehr, 450 U.S. at 188-91. Rather, such considerations are governed by 35 U.S.C. § 102 (novelty) and § 103 (non-obviousness). Diehr, 450 U.S. at 188-91. Although § 101 refers to "new and useful" processes, it is overall "a general statement of the type of subject matter that is eligible for patent protection 'subject to the conditions and requirements of this title.'" Diehr, 450 U.S. at 189 (quoting § 101). As the legislative history of § 101 indicates, Congress did not intend the "new and useful" language of § 101 to constitute an independent requirement of novelty or non-obviousness distinct from the more specific and detailed requirements of §§ 102 and 103, respectively. Diehr, 450 U.S. at 190-91.15 So here, it is irrelevant to the § 101 analysis whether Applicants' claimed process is novel or non-obvious.

Second, the Court has made clear that it is inappropriate to determine the patent-eligibility of a claim as a whole based on whether selected limitations constitute patent-

17

eligible subject matter. Flook, 437 U.S. at 594 ("Our approach to respondent's application is, however, not at all inconsistent with the view that a patent claim must be considered as a whole."); Diehr, 450 U.S. at 188 ("It is inappropriate to dissect the claims into old and new elements and then to ignore the presence of the old elements in the analysis."). After all, even though a fundamental principle itself is not patent-eligible, processes incorporating a fundamental principle may be patent-eligible. Thus, it is irrelevant that any individual step or limitation of such processes by itself would be unpatentable under § 101. See In re Alappat, 33 F.3d 1526, 1543-44 (Fed. Cir. 1994) (en banc) (citing Diehr, 450 U.S. at 187).

III.

In the years following the Supreme Court's decisions in Benson, Flook, and Diehr, our predecessor court and this court have reviewed numerous cases presenting a wide variety of process claims, some in technology areas unimaginable when those seminal Supreme Court cases were heard.16 Looking to these precedents, we find a wealth of detailed guidance and helpful examples on how to determine the patent-eligibility of process claims.

A.

Before we turn to our precedents, however, we first address the issue of whether several other purported articulations of § 101 tests are valid and useful. The first of these is known as the Freeman-Walter-Abele test after the three decisions of our predecessor court that formulated and then refined the test: In re Freeman, 573 F.2d 1237 (CCPA 1978); In re Walter, 618 F.2d 758 (CCPA 1980); and In re Abele, 684 F.2d

18

902 (CCPA 1982). This test, in its final form, had two steps: (1) determining whether the claim recites an "algorithm" within the meaning of Benson, then (2) determining whether that algorithm is "applied in any manner to physical elements or process steps." Abele, 684 F.2d at 905-07.

Some may question the continued viability of this test, arguing that it appears to conflict with the Supreme Court's proscription against dissecting a claim and evaluating patent-eligibility on the basis of individual limitations. See Flook, 437 U.S. at 594 (requiring analysis of claim as a whole in § 101 analysis); see also AT&T, 172 F.3d at 1359; State St., 149 F.3d at 1374. In light of the present opinion, we conclude that the Freeman-Walter-Abele test is inadequate. Indeed, we have already recognized that a claim failing that test may nonetheless be patent-eligible. See In re Grams, 888 F.2d 835, 838-39 (Fed. Cir. 1989). Rather, the machine-or-transformation test is the applicable test for patent-eligible subject matter.17

The second articulation we now revisit is the "useful, concrete, and tangible result" language associated with State Street, although first set forth in Alappat. State St., 149 F.3d at 1373 ("Today, we hold that the transformation of data, representing discrete dollar amounts, by a machine through a series of mathematical calculations into a final share price, constitutes a [patent-eligible invention] because it produces 'a useful, concrete and tangible result' . . . .");18 Alappat, 33 F.3d at 1544 ("This is not a

19

disembodied mathematical concept which may be characterized as an 'abstract idea,' but rather a specific machine to produce a useful, concrete, and tangible result."); see also AT&T, 172 F.3d at 1357 ("Because the claimed process applies the Boolean principle to produce a useful, concrete, tangible result without pre-empting other uses of the mathematical principle, on its face the claimed process comfortably falls within the scope of § 101."). The basis for this language in State Street and Alappat was that the Supreme Court has explained that "certain types of mathematical subject matter, standing alone, represent nothing more than abstract ideas until reduced to some type of practical application." Alappat, 33 F.3d at 1543; see also State St., 149 F.3d at 1373. To be sure, a process tied to a particular machine, or transforming or reducing a particular article into a different state or thing, will generally produce a "concrete" and "tangible" result as those terms were used in our prior decisions. But while looking for "a useful, concrete and tangible result" may in many instances provide useful indications of whether a claim is drawn to a fundamental principle or a practical application of such a principle, that inquiry is insufficient to determine whether a claim is patent-eligible under § 101. And it was certainly never intended to supplant the Supreme Court's test. Therefore, we also conclude that the "useful, concrete and tangible result" inquiry is inadequate and reaffirm that the machine-or-transformation test outlined by the Supreme Court is the proper test to apply.19

20

We next turn to the so-called "technological arts test" that some amici 20 urge us to adopt. We perceive that the contours of such a test, however, would be unclear because the meanings of the terms "technological arts" and "technology" are both ambiguous and ever-changing.21 And no such test has ever been explicitly adopted by the Supreme Court, this court, or our predecessor court, as the Board correctly observed here. Therefore, we decline to do so and continue to rely on the machine-or-transformation test as articulated by the Supreme Court.

We further reject calls for categorical exclusions beyond those for fundamental principles already identified by the Supreme Court.22 We rejected just such an exclusion in State Street, noting that the so-called "business method exception" was unlawful and that business method claims (and indeed all process claims) are "subject to the same legal requirements for patentability as applied to any other process or method." 149 F.3d at 1375-76. We reaffirm this conclusion.23

21

Lastly, we address a possible misunderstanding of our decision in Comiskey. Some may suggest that Comiskey implicitly applied a new § 101 test that bars any claim reciting a mental process that lacks significant "physical steps." We did not so hold, nor did we announce any new test at all in Comiskey. Rather, we simply recognized that the Supreme Court has held that mental processes, like fundamental principles, are excluded by § 101 because "'[p]henomena of nature, though just discovered, mental processes, and abstract intellectual concepts . . . are the basic tools of scientific and technological work.'" Comiskey, 499 F.3d at 1377 (quoting Benson, 409 U.S. at 67) (emphasis added). And we actually applied the machine-or-transformation test to determine whether various claims at issue were drawn to patent-eligible subject matter.24 Id. at 1379 ("Comiskey has conceded that these claims do not require a machine, and these claims evidently do not describe a process of manufacture or a process for the alteration of a composition of matter."). Because those claims failed the machine-or-transformation test, we held that they were drawn solely to a fundamental principle, the mental process of arbitrating a dispute, and were thus not patent-eligible under § 101. Id.

22

Further, not only did we not rely on a "physical steps" test in Comiskey, but we have criticized such an approach to the § 101 analysis in earlier decisions. In AT&T, we rejected a "physical limitations" test and noted that "the mere fact that a claimed invention involves inputting numbers, calculating numbers, outputting numbers, and storing numbers, in and of itself, would not render it nonstatutory subject matter." 172 F.3d at 1359 (quoting State St., 149 F.3d at 1374). The same reasoning applies when the claim at issue recites fundamental principles other than mathematical algorithms. Thus, the proper inquiry under § 101 is not whether the process claim recites sufficient "physical steps," but rather whether the claim meets the machine-or-transformation test. 25 As a result, even a claim that recites "physical steps" but neither recites a particular machine or apparatus, nor transforms any article into a different state or thing, is not drawn to patent-eligible subject matter. Conversely, a claim that purportedly lacks any "physical steps" but is still tied to a machine or achieves an eligible transformation passes muster under § 101. 26

B.

With these preliminary issues resolved, we now turn to how our case law elaborates on the § 101 analysis set forth by the Supreme Court. To the extent that some of the reasoning in these decisions relied on considerations or tests, such as "useful, concrete and tangible result," that are no longer valid as explained above, those aspects of the decisions should no longer be relied on. Thus, we reexamine the facts of

23

certain cases under the correct test to glean greater guidance as to how to perform the § 101 analysis using the machine-or-transformation test.

The machine-or-transformation test is a two-branched inquiry; an applicant may show that a process claim satisfies § 101 either by showing that his claim is tied to a particular machine, or by showing that his claim transforms an article. See Benson, 409 U.S. at 70. Certain considerations are applicable to analysis under either branch. First, as illustrated by Benson and discussed below, the use of a specific machine or transformation of an article must impose meaningful limits on the claim's scope to impart patent-eligibility. See Benson, 409 U.S. at 71-72. Second, the involvement of the machine or transformation in the claimed process must not merely be insignificant extra-solution activity. See Flook, 437 U.S. at 590.

As to machine implementation, Applicants themselves admit that the language of claim 1 does not limit any process step to any specific machine or apparatus. See Appellants' Br. at 11. As a result, issues specific to the machine implementation part of the test are not before us today. We leave to future cases the elaboration of the precise contours of machine implementation, as well as the answers to particular questions, such as whether or when recitation of a computer suffices to tie a process claim to a particular machine.

We will, however, consider some of our past cases to gain insight into the transformation part of the test. A claimed process is patent-eligible if it transforms an article into a different state or thing. This transformation must be central to the purpose of the claimed process. But the main aspect of the transformation test that requires clarification here is what sorts of things constitute "articles" such that their

24

transformation is sufficient to impart patent-eligibility under § 101. It is virtually self-evident that a process for a chemical or physical transformation of physical objects or substances is patent-eligible subject matter. As the Supreme Court stated in Benson:
[T]he arts of tanning, dyeing, making waterproof cloth, vulcanizing India rubber, smelting ores . . . are instances, however, where the use of chemical substances or physical acts, such as temperature control, changes articles or materials. The chemical process or the physical acts which transform the raw material are, however, sufficiently definite to confine the patent monopoly within rather definite bounds.
409 U.S. at 70 (quoting Corning v. Burden, 56 U.S. (15 How.) 252, 267-68 (1854)); see also Diehr, 450 U.S. at 184 (process of curing rubber); Tilghman, 102 U.S. at 729 (process of reducing fats into constituent acids and glycerine).

The raw materials of many information-age processes, however, are electronic signals and electronically-manipulated data. And some so-called business methods, such as that claimed in the present case, involve the manipulation of even more abstract constructs such as legal obligations, organizational relationships, and business risks. Which, if any, of these processes qualify as a transformation or reduction of an article into a different state or thing constituting patent-eligible subject matter?

Our case law has taken a measured approach to this question, and we see no reason here to expand the boundaries of what constitutes patent-eligible transformations of articles.

Our predecessor court's mixed result in Abele illustrates this point. There, we held unpatentable a broad independent claim reciting a process of graphically displaying variances of data from average values. Abele, 684 F.2d at 909. That claim did not specify any particular type or nature of data; nor did it specify how or from where the data was obtained or what the data represented. Id.; see also In re Meyer, 688 F.2d

25

789, 792-93 (CCPA 1982) (process claim involving undefined "complex system" and indeterminate "factors" drawn from unspecified "testing" not patent-eligible). In contrast, we held one of Abele's dependent claims to be drawn to patent-eligible subject matter where it specified that "said data is X-ray attenuation data produced in a two dimensional field by a computed tomography scanner." Abele, 684 F.2d at 908-09. This data clearly represented physical and tangible objects, namely the structure of bones, organs, and other body tissues. Thus, the transformation of that raw data into a particular visual depiction of a physical object on a display was sufficient to render that more narrowly-claimed process patent-eligible.

We further note for clarity that the electronic transformation of the data itself into a visual depiction in Abele was sufficient; the claim was not required to involve any transformation of the underlying physical object that the data represented. We believe this is faithful to the concern the Supreme Court articulated as the basis for the machine-or-transformation test, namely the prevention of pre-emption of fundamental principles. So long as the claimed process is limited to a practical application of a fundamental principle to transform specific data, and the claim is limited to a visual depiction that represents specific physical objects or substances, there is no danger that the scope of the claim would wholly pre-empt all uses of the principle.

This court and our predecessor court have frequently stated that adding a data-gathering step to an algorithm is insufficient to convert that algorithm into a patent-eligible process. E.g., Grams, 888 F.2d at 840 (step of "deriv[ing] data for the algorithm will not render the claim statutory"); Meyer, 688 F.2d at 794 ("[data-gathering] step[s] cannot make an otherwise nonstatutory claim statutory"). For example, in Grams we

26

held unpatentable a process of performing a clinical test and, based on the data from that test, determining if an abnormality existed and possible causes of any abnormality. 888 F.2d at 837, 841. We rejected the claim because it was merely an algorithm combined with a data-gathering step. Id. at 839-41. We note that, at least in most cases, gathering data would not constitute a transformation of any article. A requirement simply that data inputs be gathered--without specifying how--is a meaningless limit on a claim to an algorithm because every algorithm inherently requires the gathering of data inputs. Grams, 888 F.2d at 839-40. Further, the inherent step of gathering data can also fairly be characterized as insignificant extra-solution activity. See Flook, 437 U.S. at 590.

Similarly, In re Schrader presented claims directed to a method of conducting an auction of multiple items in which the winning bids were selected in a manner that maximized the total price of all the items (rather than to the highest individual bid for each item separately). 22 F.3d 290, 291 (Fed. Cir. 1994). We held the claims to be drawn to unpatentable subject matter, namely a mathematical optimization algorithm. Id. at 293-94. No specific machine or apparatus was recited. The claimed method did require a step of recording the bids on each item, though no particular manner of recording (e.g., on paper, on a computer) was specified. Id. But, relying on Flook, we held that this step constituted insignificant extra-solution activity. Id. at 294.

IV.

We now turn to the facts of this case. As outlined above, the operative question before this court is whether Applicants' claim 1 satisfies the transformation branch of the machine-or-transformation test.

27

We hold that the Applicants' process as claimed does not transform any article to a different state or thing. Purported transformations or manipulations simply of public or private legal obligations or relationships, business risks, or other such abstractions cannot meet the test because they are not physical objects or substances, and they are not representative of physical objects or substances. Applicants' process at most incorporates only such ineligible transformations. See Appellants' Br. at 11 ("[The claimed process] transforms the relationships between the commodity provider, the consumers and market participants . . . ."). As discussed earlier, the process as claimed encompasses the exchange of only options, which are simply legal rights to purchase some commodity at a given price in a given time period. See J.A. at 86-87. The claim only refers to "transactions" involving the exchange of these legal rights at a "fixed rate corresponding to a risk position." See 892 application cl.1. Thus, claim 1 does not involve the transformation of any physical object or substance, or an electronic signal representative of any physical object or substance. Given its admitted failure to meet the machine implementation part of the test as well, the claim entirely fails the machine-or-transformation test and is not drawn to patent-eligible subject matter.

Applicants' arguments are unavailing because they rely on incorrect or insufficient considerations and do not address their claim's failure to meet the requirements of the Supreme Court's machine-or-transformation test. First, they argue that claim 1 produces "useful, concrete and tangible results." But as already discussed, this is insufficient to establish patent-eligibility under § 101. Applicants also argue that their claimed process does not comprise only "steps that are totally or substantially practiced in the mind but clearly require physical activity which have [sic] a tangible

28

result." Appellants' Br. at 9. But as previously discussed, the correct analysis is whether the claim meets the machine-or-transformation test, not whether it recites "physical steps." Even if it is true that Applicant's claim "can only be practiced by a series of physical acts" as they argue, see id. at 9, its clear failure to satisfy the machine-or-transformation test is fatal. Thus, while we agree with Applicants that the only limit to patent-eligibility imposed by Congress is that the invention fall within one of the four categories enumerated in § 101, we must apply the Supreme Court's test to determine whether a claim to a process is drawn to a statutory "process" within the meaning of § 101. Applied here, Applicants' claim fails that test so it is not drawn to a "process" under § 101 as that term has been interpreted.

On the other hand, while we agree with the PTO that the machine-or- transformation test is the correct test to apply in determining whether a process claim is patent-eligible under § 101, we do not agree, as discussed earlier, that this amounts to a "technological arts" test. See Appellee's Br. at 24-28. Neither the PTO nor the courts may pay short shrift to the machine-or-transformation test by using purported equivalents or shortcuts such as a "technological arts" requirement. Rather, the machine-or-transformation test is the only applicable test and must be applied, in light of the guidance provided by the Supreme Court and this court, when evaluating the patent-eligibility of process claims. When we do so here, however, we must conclude, as the PTO did, that Applicants' claim fails the test.

Applicants' claim is similar to the claims we held unpatentable under § 101 in Comiskey. There, the applicant claimed a process for mandatory arbitration of disputes regarding unilateral documents and bilateral "contractual" documents in which

29

arbitration was required by the language of the document, a dispute regarding the document was arbitrated, and a binding decision resulted from the arbitration. Comiskey, 499 F.3d at 1368-69. We held the broadest process claims unpatentable under § 101 because "these claims do not require a machine, and these claims evidently do not describe a process of manufacture or a process for the alteration of a composition of matter." Id. at 1379. We concluded that the claims were instead drawn to the "mental process" of arbitrating disputes, and that claims to such an "application of [only] human intelligence to the solution of practical problems" is no more than a claim to a fundamental principle. Id. at 1377-79 (quoting Benson, 409 U.S. at 67 ("[M]ental processes, and abstract intellectual concepts are not patentable, as they are the basic tools of scientific and technological work.")).

Just as the Comiskey claims as a whole were directed to the mental process of arbitrating a dispute to decide its resolution, the claimed process here as a whole is directed to the mental and mathematical process of identifying transactions that would hedge risk. The fact that the claim requires the identified transactions actually to be made does no more to alter the character of the claim as a whole than the fact that the claims in Comiskey required a decision to actually be rendered in the arbitration--i.e., in neither case do the claims require the use of any particular machine or achieve any eligible transformation.

We have in fact consistently rejected claims like those in the present appeal and in Comiskey. For example, in Meyer, the applicant sought to patent a method of diagnosing the location of a malfunction in an unspecified multi-component system that assigned a numerical value, a "factor," to each component and updated that value

30

based on diagnostic tests of each component. 688 F.2d at 792-93. The locations of any malfunctions could thus be deduced from reviewing these "factors." The diagnostic tests were not identified, and the "factors" were not tied to any particular measurement; indeed they could be arbitrary. Id. at 790. We held that the claim was effectively drawn only to "a mathematical algorithm representing a mental process," and we affirmed the PTO's rejection on § 101 grounds. Id. at 796. No machine was recited in the claim, and the only potential "transformation" was of the disembodied "factors" from one number to another. Thus, the claim effectively sought to pre-empt the fundamental mental process of diagnosing the location of a malfunction in a system by noticing that the condition of a particular component had changed. And as discussed earlier, a similar claim was rejected in Grams.27 See 888 F.2d at 839-40 (rejecting claim to process of diagnosing "abnormal condition" in person by identifying and noticing discrepancies in results of unspecified clinical tests of different parts of body).

Similarly to the situations in Meyer and Grams, Applicants here seek to claim a non-transformative process that encompasses a purely mental process of performing requisite mathematical calculations without the aid of a computer or any other device, mentally identifying those transactions that the calculations have revealed would hedge each other's risks, and performing the post-solution step of consummating those transactions. Therefore, claim 1 would effectively pre-empt any application of the

31

fundamental concept of hedging and mathematical calculations inherent in hedging (not even limited to any particular mathematical formula). And while Applicants argue that the scope of this pre-emption is limited to hedging as applied in the area of consumable commodities, the Supreme Court's reasoning has made clear that effective pre-emption of all applications of hedging even just within the area of consumable commodities is impermissible. See Diehr, 450 U.S. at 191-92 (holding that field-of-use limitations are insufficient to impart patent-eligibility to otherwise unpatentable claims drawn to fundamental principles). Moreover, while the claimed process contains physical steps (initiating, identifying), it does not involve transforming an article into a different state or thing. Therefore, Applicants' claim is not drawn to patent-eligible subject matter under § 101.

CONCLUSION

Because the applicable test to determine whether a claim is drawn to a patent-eligible process under § 101 is the machine-or-transformation test set forth by the Supreme Court and clarified herein, and Applicants' claim here plainly fails that test, the decision of the Board is

AFFIRMED.

1 Although our decision in Comiskey may be misread by some as requiring in every case that the examiner conduct a § 101 analysis before assessing any other issue of patentability, we did not so hold. As with any other patentability requirement, an examiner may reject a claim solely on the basis of § 101. Or, if the examiner deems it appropriate, she may reject the claim on any other ground(s) without addressing § 101. But given that § 101 is a threshold requirement, claims that are clearly drawn to unpatentable subject matter should be identified and rejected on that basis. Thus, an examiner should generally first satisfy herself that the application's claims are drawn to patent-eligible subject matter.

2 As a result, we decline to discuss In re Nuijten because that decision primarily concerned whether a claim to an electronic signal was drawn to a patent-eligible manufacture. 500 F.3d 1346, 1356-57 (Fed. Cir. 2007). We note that the PTO did not dispute that the process claims in Nuijten were drawn to patent-eligible subject matter under §101 and allowed those claims.

3 Congress provided a definition of "process" in 35 U.S.C. § 100(b): "The term 'process' means process, art or method, and includes a new use of a known process, machine, manufacture, composition of matter, or material." However, this provision is unhelpful given that the definition itself uses the term "process."

4 The Patent Act of 1793 originally used the term "art" rather than "process," which remained unchanged until Congress enacted the current version of § 101 in 1952. But the Supreme Court has held that this change did not alter the scope of patent eligibility over processes because "[i]n the language of the patent law, [a process] is an art." Diamond v. Diehr, 450 U.S. 175, 182-84 (1981) (quoting Cochrane v. Deener, 94 U.S. 780, 787-88 (1877)); see also Comiskey, 499 F.3d at 1375.

5 As used in this opinion, "fundamental principles" means "laws of nature, natural phenomena, and abstract ideas."

6 Mathematical algorithms have, in other cases, been identified instead as abstract ideas rather than laws of nature. See, e.g., State St., 149 F.3d at 1373. Whether either or both views are correct is immaterial since both laws of nature and abstract ideas are unpatentable under § 101. Diehr, 450 U.S. at 185.

7 While the Court did not give explicit definitions of terms such as "tied to," "transforms," or "article," a careful analysis of its opinions and the subsequent jurisprudence of this court applying those decisions, discussed infra, informs our understanding of the Court's machine-or-transformation test.

8 To the extent it may be argued that Flook did not explicitly follow the machine-or-transformation test first articulated in Benson, we note that the more recent decision in Diehr reaffirmed the machine-or-transformation test. See Diehr, 450 U.S. at 191-92. Moreover, the Diehr Court explained that Flook "presented a similar situation" to Benson and considered it consistent with the holdings of Diehr and Benson. Diehr at 186-87, 189, 191-92. We thus follow the Diehr Court's understanding of Flook.

9 We acknowledge that the Supreme Court in Benson stated that the claims at issue "were not limited . . . to any particular apparatus or machinery." 409 U.S. at 64. However, the Court immediately thereafter stated: "[The claims] purported to cover any use of the claimed method in a general-purpose digital computer of any type." Id. And, as discussed herein, the Court relied for its holding on its understanding that the claimed process pre-empted all uses of the recited algorithm because its only possible use was on a digital computer. Id. at 71-72. The Diehr Court, in discussing Benson, relied only on this latter understanding of the Benson claims. See Diehr, 450 U.S. at 185-87. We must do the same.

10 See, e.g., Br. of Amicus Curiae Am. Intellectual Prop. Law Ass'n at 17-21; Br. of Amicus Curiae Regulatory Datacorp, Inc. at 10-15.

11 We believe that the Supreme Court spoke of the machine-or- transformation test as the "clue" to patent-eligibility because the test is the tool used to determine whether a claim is drawn to a statutory "process"--the statute does not itself explicitly mention machine implementation or transformation. We do not consider the word "clue" to indicate that the machine-or-implementation test is optional or merely advisory. Rather, the Court described it as the clue, not merely "a" clue. See Benson, 409 U.S. at 70.

12 The Diehr Court stated: "[W]hen a claim containing a mathematical formula implements or applies that formula in a structure or process which, when considered as a whole, is performing a function which the patent laws were designed to protect (e.g., transforming or reducing an article to a different state or thing), then the claim satisfies the requirements of § 101." 450 U.S at 192 (emphases added). When read together with Benson and Flook, on which the Diehr Court firmly relied, we believe this statement is consistent with the machine-or-transformation test. But as we noted in AT&T, language such as the use of "e.g." may indicate the Supreme Court's recognition that the machine-or-transformation test might require modification in the future. See AT&T, 172 F.3d at 1358-59.

13 The example of the Pythagorean theorem applied to surveying techniques could also be considered an example of a mere field-of-use limitation.

14 Although the Court spoke of "postsolution" activity, we have recognized that the Court's reasoning is equally applicable to any insignificant extra-solution activity regardless of where and when it appears in the claimed process. See In re Schrader, 22 F.3d 290, 294 (Fed. Cir. 1994) (holding a simple recordation step in the middle of the claimed process incapable of imparting patent-eligibility under § 101); In re Grams, 888 F.2d 835, 839-40 (Fed. Cir. 1989) (holding a pre-solution step of gathering data incapable of imparting patent-eligibility under § 101).

15 By the same token, considerations of adequate written description, enablement, best mode, etc., are also irrelevant to the § 101 analysis because they, too, are governed by other provisions of the Patent Act. Section 101 does, however, allow for patents only on useful inventions. Brenner v. Manson, 383 U.S. 519, 532-35 (1966).

16 We note that the PTO, too, has been active in analyzing § 101 law. See, e.g., Ex parte Lundgren, 76 USPQ2d 1385 (B.P.A.I. 2004); Interim Guidelines for Examination of Patent Applications for Patent Subject Matter Eligibility, Off. Gaz. Pat. & Trademark Office, Nov. 22, 2005.

17 Therefore, in Abele, Meyer, Grams, Arrhythmia Research Technology, Inc. v. Corazonix Corp., 958 F.2d 1053 (Fed. Cir. 1992), and other decisions, those portions relying solely on the Freeman-Walter-Abele test should no longer be relied on.

18 In State Street, as is often forgotten, we addressed a claim drawn not to a process but to a machine. 149 F.3d at 1371-72 (holding that the means-plus-function elements of the claims on appeal all corresponded to supporting structures disclosed in the written description).

19 As a result, those portions of our opinions in State Street and AT&T relying solely on a "useful, concrete and tangible result" analysis should no longer be relied on.

20 See, e.g., Br. of Amicus Curiae Consumers Union et al. at 6-10; Br. of Amicus Curiae William Mitchell Coll. of Law Intellectual Prop. Inst. at 14-15.

21 Compare Appellee's Br. at 24-28 (arguing that patents should be reserved only for "technological" inventions that "involve[] the application of science or mathematics," thereby excluding "non-technological inventions" such as "activities whose ability to achieve their claimed goals depended solely on contract formation"), with Br. of Amicus Curiae Regulatory Datacorp, Inc. at 19-24 (arguing that "innovations in business, finance, and other applied economic fields plainly qualify as 'technological'" since "a fair definition of technological is 'characterized by the practical application of knowledge in a particular field'" and because modern economics has "a closer affinity to physics and engineering than to liberal arts like English literature").

22 See, e.g., Br. of Amicus Curiae Fin. Servs. Indus. at 20 ("[E]xtending patent protection to pure methods of doing business . . . is contrary to the constitutional and statutory basis for granting patent monopolies . . . .").

23 Therefore, although invited to do so by several amici, we decline to adopt a broad exclusion over software or any other such category of subject matter beyond the exclusion of claims drawn to fundamental principles set forth by the Supreme Court. See, e.g., Br. of Amicus Curiae End Software Patents; Br. of Amicus Curiae Red Hat, Inc. at 4-7. We also note that the process claim at issue in this appeal is not, in any event, a software claim. Thus, the facts here would be largely unhelpful in illuminating the distinction between those software claims that are patent-eligible and those that are not not.

24 Our statement in Comiskey that "a claim reciting an algorithm or abstract idea can state statutory subject matter only if, as employed in the process, it is embodied in, operates on, transforms, or otherwise involves another class of statutory subject matter, i.e., a machine, manufacture, or composition of matter," 499 F.3d at 1376, was simply a summarization of the Supreme Court's machine-or-transformation test and should not be understood as altering that test.

25 Thus, it is simply inapposite to the §101 analysis whether the process steps performed by software on a computer are sufficiently "physical."

26 Of course, a claimed process wherein all of the process steps may be performed entirely in the human mind is obviously not tied to any machine and does not transform any article into a different state or thing. As a result, it would not be patent-eligible under §101.

27 We note that several Justices of the Supreme Court, in a dissent to a dismissal of a writ of certiorari, expressed their view that a similar claim in Laboratory Corp. of America Holdings v. Metabolite Laboratories, Inc. was drawn to unpatentable subject matter. 126 S. Ct. 2921, 2927-28 (2006) (Breyer, J., dissenting; joined by Stevens, J., and Souter, J.). There, the claimed process only comprised the steps of: (1) "assaying a body fluid for an elevated level of total homocysteine," and (2) "correlating an elevated level of total homocysteine in said body fluid with a deficiency of cobalamin or folate." Id. at 2924.

Will This Lead To: Buh-Bye Software Patents?
Authored by: iceworm on Thursday, October 30 2008 @ 03:56 PM EDT

My thought is: all software, not just business applications, embody methods that humans use to do things. That is, accounting, word processing, and scientific programs are methods of having routine human activities done by a machine.

In the mundane world of Monday - wash day, a particular form of wash board may be patentable, but the general idea and method of using a wash board should not be patentable. Software appears to me to be in this category of embodying the general idea of doing something.

So what happens now?
Authored by: Aladdin Sane on Thursday, October 30 2008 @ 05:46 PM EDT
Does the USPTO have to go their database and find all the business method patents and draw a line through them (white-out, black Sharpie redaction, something)?

Or do people have to sue each and every business method patent holder to use the method described in each and every business method patent?

BTW, my understanding is that Dell is a big fan of business method patents.

Hold the champagne!
Authored by: dwheeler on Thursday, October 30 2008 @ 07:09 PM EDT
Hold that champagne! I don't think this ruling is as wonderful as you're making
it. This ruling EXPLICITLY continues its support for business method patents,
and seems to be explicitly supporting software patents too.

See page 21: "We rejected just such an
exclusion [of business method patents] in State Street, noting that the
so-called "business method exception" was
unlawful and that business method claims (and indeed all process claims) are
"subject to the same legal requirements for patentability as applied to any
other process or method." 149 F.3d at 1375-76. We reaffirm this
conclusion."

In the Bilski case, even the Patent Office agrees that it shouldn't be patented
- and the patent office gleefully grants patents that "obviously"
shouldn't be granted (well, obvious to most software developers anyway). The
patent office was happy to grant display XORing, the setuid bit, and other
nonsense. In fact, this whole case shows that the patent office is having
trouble figuring out how to say 'no'. It seems to say 'yes' so often that it's
having trouble justifying ANY limits on patentability that is consistent and
justifiable.

This ruling states a few limits, but I suspect that they will be easily
subverted. "Transforms an article into a different state or thing"?
ANY process produces SOME different "state or thing", so people will
work hard to drive through that loophole, slowly distorting its meaning.

"Useful, concrete and tangible results" / "tied to a
machine" ?

A stop to patent saber-rattling by Microsoft?
Authored by: rehdon on Friday, October 31 2008 @ 07:58 AM EDT
I wonder if this will be enough to stop Microsoft's obscure threats (I could
just call them FUD, I know) about patent infringements occurring in the Linux'
kernel. What do you think? I surely hope so.

Also, it will be interesting to follow Mono and Silverlight from now on: in my
humble opinion Microsoft encouraged development of their technologies on Linux
to be able to cash on them some time in the future, but if the prospective
patent threats are (at least partially) defanged the free/open source world
could embrace them having less to fear.

The Bilski Decision Is In: Buh-Bye [Most] Business Methods Patents - As text & updated 3Xs

I want to highlight a comment Gene Quinn himself left on his blog. I couldn't
put it in words any better: this is why software patents suck.

That is exactly why data processing can't be subject matter.

He later talks about non-obviousness and prior art, so that makes it complete.
Of course his conclusion is the exact opposite of mine, but those words are
priceless.

THE FEDERAL CIRCUIT - AYE AYE BOSS
Authored by: rsteinmetz70112 on Friday, October 31 2008 @ 10:41 AM EDT
For years the Federal Circuit has been enlarging patents beyond all reason.
Recently the Supreme Court stepped in and indicated that they had reached their
limit.

It looks like the Federal Circuit got the message loud and clear.

A Framework for Distinguishing Working and Broken Patent Systems
Authored by: Anonymous on Friday, October 31 2008 @ 11:38 AM EDT
I think the following framework might be useful in understanding how a patent system should work and what the specific problems are with some of the things being patented now.

Example of a Working Patent System

It's 70 years ago and "Inventor" invents a remarkable new mousetrap with an ingenious design that works much better than anything on the market.

Without a patent system: as soon as Inventor tries to sell a few through a neighbourhood hardware store, the big manufacturing chains see it. With their extensive production facilities and distribution network they build their own (based on Inventor's design) much more cheaply and sell it in every store. Inventor gets very little profit from his invention and the big companies get a lot.

With the patent system, the big companies have to negotiate a royalty payment with Inventor before they can make and sell the mousetrap. This a restraint on trade, but that's fair because they're only able to build the mousetrap because of Inventor's work, so it's only fair they have to pay something in return for the benefit they've gained. Also, commercial trade is a sphere in which some form of regulation is always present so this restraint is just an additional regulation.

In contrast to the restraint on trade, there is no restraint on speech. Indeed, the patent system encourages dissemination and discussion of the new design. It is taught in classes and described in books.

There is also no practical restraint on individual's private lives. If Handyman wants to tinker in his/her basement and build his/her own mousetrap out of scrap materials, nobody's going to care. I don't know whether it's technically permitted or not under patent law, but in practice nobody would care. Unless of course he/she were to start making and selling them out of the home, but then that would be commercial trade and the restraint would kick in. Or if a business were to build it's own 1000 mousetraps for its premises instead of buying them from a royalty-paying manufacturer, then the patent holder would probably sue, but that's because it's a measurable loss of business.

Characteristics of a Working Patent System

  1. It applies to tangible things (machines built according to an ingenious design, or substances made by an ingenious process).
  2. It protects the inventor of the design/process by imposing a limited monopoly on the manufacture and sale of these tangible things.
  3. This monopoly constitutes restraint of trade, an area in which restraints and regulations are appropriate. This particular restraint is fair exchange for the benefit gained in the ability to manufacture these tangible things, an ability which is only possible because of Inventor's work.
  4. There is no restraint on speech. Dissemination and discussion of the design is encouraged.
  5. There is no practical restraint on the private lives of individuals and their freedom to tinker and build.
  6. The private lives and inner working of companies is restrained only because, if the company were to manufacture these things for its own use, it would be instead of buying them from an authorized manufacturer.

The Problem with Patents on Business Methods

Patents on business methods impose restraint on speech or restraint on private lives, areas in which government restraint is inappropriate, rather than restraint on commercial trade where it is more appropriate. In order to prohibit a financial advisor from implementing a patented investment method with a private client, you either have to restrain the advisor's speech (so he/she has to lie when answering a client's question about what the best strategy is) or restrain the client's ability to make personal investments based on information provided by the advisor, whch is an inappropriate restraint on the client's private life.

Even if one were to say that a business method patent weren't enforceable on an adviser with a private client but only on a business's internal activities, it's still a much more unfair restraint because it means a business that doesn't want to pay royalties is prohibited from carrying out its normal affairs in a particular manner, rather than being prohibited from making its own tangible product instead of buying it elsewhere. The former imposes restraints on how the business is allowed to operate. The latter imposes no such restraint, merely a restraint on where it is allowed to obtain certain tangible products.

The Problem with Too-Obvious Patents

The particular method in this patent is probably also one which someone who had never heard of this patent or its "inventor" would quite likely end up "infringing" when trying to use common sense and general knowledge to conduct business. The whole reason patent systems are "fair" is that they restrain manufacture which would not have been possible without the inventor's work, so the monopoly grant is a fair exchange for the benefit gained.

Of course, independent invention (and therefore unwitting infringement and the unfair need to pay a royalty to someone from whom you have received no benefit) is always possible, but in a fair patent system it needs to be so unlikely that the few times it happens are an acceptable price to pay for the benefits of the patent system. Once it becomes even "fairly likely", the patent system is broken.

The Problem With Software

The problem with patenting software is that software blurs the line between a tangible invention and speech. On the one hand, there's a lot of inventiveness involved, and without patent protection small software inventors are vulnerable to having their ideas swallowed up just like the hypothetical mousetrap inventor above. That's why advocates of software patents push for them, at least in the case of particularly ingenious pieces of software. (Most software patents are for things so obvious they should be disallowed on those grounds, not just because they're software).

On the other hand, since the dissemination of software does not require the manufacture or sale of a tangible thing, attempting to grant a monopoly runs the risk of interfering with freedom of speech. Also, because every home is equipped with a computer which can "manufacture" a tangible instance of a compiled and operating computer program based solely on "information", the distinction is blurred between commercial trade and the private lives of individual software developers.

To see this dilemma more clearly, imagine a future when every home has a robot capable of manufacturing anything you tell it to, once you tell it the key ideas of how it's to be made. In such a future, a working patent system would no longer be possible. For once you encourage dissemination of the precise design information on how an object is to be built (which is what a patent system is supposed to encourage), ordinary individuals can then pass the idea on to the robot and bingo! They have the item they need just as if they'd bought it in a store. So you can no longer grant a monopoly on the manufacture and sale of the product without also granting a monopoly on the communication of ideas.

What is the solution? I think in this hypothetical future one would need to abandon the patent system altogether. This would be reasonable because then the reasons for the patent system would no longer be present. Patents were intended to disseminate information and knowledge, and protect and encourage inventors. If products are no longer bought in stores but are built by individuals based on design information, then the first goal of the patent system has already been met. And since information and knowledge has a zero dissemination cost and can be spread widely on the Internet by anyone, the advantage by which the big hardware companies could squash the mousetrap inventor (lower production costs and a wider distribution network) are no longer present.

For software, the situation is somewhat similar to this hypothetical future. I'm not sure it's quite the same; I think big software companies probably still do have some edge over small developers in terms of distribution. But perhaps the same arguments can still be made to disallow software patents: that not only do software patents result in unfair restraint on speech and private activities, but also the need for them is less because the zero-margin cost of distribution and ability of anyone to distribute over the Internet lessen the need for patents to protect small inventors and render the goal of wide dissemination of information more naturally reachable than in the old manufacturing days.

It was said that Novel sold out to the devil with the
MS$ patent deal. In light of this decision, is Novel
now vindicated, and MS$ out a half billion?

Maybe ... I thinks ... Novel was "crazy like a fox."

Nice Climb-down - should help stop software patents in the EU.
Authored by: SilverWave on Saturday, November 01 2008 @ 12:41 PM EDT
A lot of the argument in the EU was along the lines of "Look we need to
match the system in the USA to be competitive."

This decision allows us all to reply "Hah the USA got it wrong, saw the
problems it caused and corrected it!"

Nice :)

I think its a good decision pity they didn't go further and out right ban them
though.

A lot of the dodgy MS patents, all the ones they wouldn't point to in any detail
or give any specifics to, just dried up and blew away.

Even Nicer :P

Bilski creates business for systems consultants
Authored by: Anonymous on Sunday, November 02 2008 @ 07:01 AM EST
The Bilski decision is good news, but not for the reason you think.

The biggest winners from the Bilski decision might be systems consultants. As a
US patent agent specializing in business method patents, one of the strategies
I’ve emphasized for software professionals seeking a patent is for them to spend
a little extra money to hire a systems consultant to spec out the hardware
implementation of their inventions. We then include those specifications in the
patent application with the tech consultant as a coinventor.

The strategy has been very successful and with Bilski taking such a strong stand
on the importance of tying a new software invention to a “particular machine”,
it should be even more effective in the future.

Depressing
Authored by: Jose on Monday, November 03 2008 @ 04:05 PM EST
Patent law has to change through Congress because it is unfair and taxing on
society. It might even be Unconstitutional.

With respect to this new development, a huge loophole seems to exist because
many useful effects can be linked to something that in many cases is needed in
order to make use of a computer, eg, a display monitor.

From pgs 25 and 26:

>> Our predecessor court's mixed result in Abele illustrates this point.
There, we held unpatentable a broad independent claim reciting a process of
graphically displaying variances of data from average values. Abele, 684 F.2d at
909. That claim did not specify any particular type or nature of data; nor did
it specify how or from where the data was obtained or what the data represented.
Id.; see also In re Meyer, 688 F.2d

>> 789, 792-93 (CCPA 1982) (process claim involving undefined
"complex system" and indeterminate "factors" drawn from
unspecified "testing" not patent-eligible). In contrast, we held one
of Abele's dependent claims to be drawn to patent-eligible subject matter where
it specified that "said data is X-ray attenuation data produced in a two
dimensional field by a computed tomography scanner." Abele, 684 F.2d at
908-09. This data clearly represented physical and tangible objects, namely the
structure of bones, organs, and other body tissues. Thus, the transformation of
that raw data into a particular visual depiction of a physical object on a
display was sufficient to render that more narrowly-claimed process
patent-eligible.

>> We further note for clarity that the electronic transformation of the
data itself into a visual depiction in Abele was sufficient; the claim was not
required to involve any transformation of the underlying physical object that
the data represented. We believe this is faithful to the concern the Supreme
Court articulated as the basis for the machine-or-transformation test, namely
the prevention of pre-emption of fundamental principles. So long as the claimed
process is limited to a practical application of a fundamental principle to
transform specific data, and the claim is limited to a visual depiction that
represents specific physical objects or substances, there is no danger that the
scope of the claim would wholly pre-empt all uses of the principle.

Continuing on 26 and 27, we see examples of what is not patentable, but these
cases fail because of *trivial* combinations. The implied suggestion is that a
not-so-trivial combination might be patentable.

>> This court and our predecessor court have frequently stated that
adding a data-gathering step to an algorithm is insufficient to convert that
algorithm into a patent-eligible process. E.g., Grams, 888 F.2d at 840 (step of
"deriv[ing] data for the algorithm will not render the claim
statutory"); Meyer, 688 F.2d at 794 ("[data-gathering] step[s] cannot
make an otherwise nonstatutory claim statutory"). For example, in Grams we

>> held unpatentable a process of performing a clinical test and, based on
the data from that test, determining if an abnormality existed and possible
causes of any abnormality. 888 F.2d at 837, 841. We rejected the claim because
it was merely an algorithm combined with a data-gathering step. Id. at 839-41.
We note that, at least in most cases, gathering data would not constitute a
transformation of any article. A requirement simply that data inputs be
gathered--without specifying how--is a meaningless limit on a claim to an
algorithm because every algorithm inherently requires the gathering of data
inputs. Grams, 888 F.2d at 839-40. Further, the inherent step of gathering data
can also fairly be characterized as insignificant extra-solution activity. See
Flook, 437 U.S. at 590.

>> Similarly, In re Schrader presented claims directed to a method of
conducting an auction of multiple items in which the winning bids were selected
in a manner that maximized the total price of all the items (rather than to the
highest individual bid for each item separately). 22 F.3d 290, 291 (Fed. Cir.
1994). We held the claims to be drawn to unpatentable subject matter, namely a
mathematical optimization algorithm. Id. at 293-94. No specific machine or
apparatus was recited. The claimed method did require a step of recording the
bids on each item, though no particular manner of recording (e.g., on paper, on
a computer) was specified. Id. But, relying on Flook, we held that this step
constituted insignificant extra-solution activity. Id. at 294.

I think Congress is going to have to see what FOSS is creating and realize that
software patents hold back progress. They unfairly enrich a few (monopolies are
being granted for long periods of time) to the detriment of many inventors
(*many* because of the low costs to design and implement software inventions).

As for obvious vs not obvious.. Whatever happened to allowing competition among
the 20 "smartest" developers for inventions not obvious to the
millions of others but obvious to this small group? Why reward Jack Smith with a
monopoly and deny Jane and the 19 other geniuses a chance to make the discovery
for themselves within a short time and then compete? It's not as if closed
source and trade secret protections don't already exist.

Adding lubrication to patent creation for FOSS defense?
Authored by: Jose on Monday, November 03 2008 @ 04:12 PM EST
And this next link
http://boycottnovell.com/2008/10/30/combat-free-software-bait/ gives a
suggestion that may help the creation of FOSS patents, but it may actually
hinder it if it alienates some folks.

The main points (not sure if the email covered these all) are that when you
contribute to a project working under this model, you give permission to others
to draw up a patent on anything you might partially invent. They'd list you as a
co-author. They would get rights as might you. Importantly, that project and
other FOSS would automatically get a liberal patent license revokable only for
various violations (like attacking another FOSS project with patents).

>> The issue is that patents aren't granted automatically as are
copyrights. You have to write them up. If we add *lubrication* as suggested
above, we can have legal and patent-minded individuals contribute to the
community while those that simply want to code things up and not deal with
patents, also go forward.

>> "If we can't beat patent law, at least leverage it for good
cause." As things are, if we make an "invention" (and don’t
patent it), we open it up to the world to use (like BSD), but if Microsoft
creates one (and patents it), we can't use theirs. In both cases, a person stood
on shoulders of giants, but only one of these "inventors" allowed
others to stand even higher... and it was the nice inventors (FOSS) that ended
up with the short end of the stick! That is bad way to reward innovation -- a
fundamental screw-up of patent law.

Also, I am not sure how to attract patent writers (even trolls) to our side. If
we give them the ability to use the patents against closed source products (eg,
they get rights to license, sue, etc, and a cut of royalties) but kept some
interests for ourselves, could this provoke a patent attack in return? What if
we gave up all interests in the patents (keeping the protections for FOSS, of
course)?

Also, how would we define "any FOSS project," which would be an ideal
thing to protect.

And would the patent writers be able to write multiple compatible patents
(usable in combinations) so that they would keep most of the powerful stuff for
themselves in the adjuct patents?

For those with times on their hands to read through IRC logs, see also the
discussion here (mostly under my username):
http://boycottnovell.com/2008/10/30/irc-log-29102008/ .

In short, this sounded nice to me initially, but I'm not sure if it would ever
be put into practice.
