Back on July 18, I reported that then-Caldera employee Christoph Hellwig contributed to the Linux kernel. One commenter opined that if he broke an NDA, he was going to be in trouble. Ever since, I have been looking for proof positive that Caldera's employees -- and we have found more than one -- contributed with the knowledge and approval of their employer. Here's what I found, plus something helpful from mathfox, a Groklaw reader:I scanned the linux-2.6.0-test2 source tree for the name Caldera and found a few occurrences: In the file net/ipx/af_ipx.c the following text can be found:
* Portions Copyright (c) 1995 Caldera, Inc.
* Neither Greg Page nor Caldera, Inc. admit liability nor provide
* warranty for any of this software. This material is provided
* "AS-IS" and at no charge.
They knew the implications of the GPL. It is likely that the code was
contributed to Linux a few years after 1995, but before 2000.
In 1997-1998 Caldera contributed the ThunderLAN (tlan) drivers.
During the year 2001 several bugfixes were provided by engineers from
Caldera Germany. As an example: Marcus Meissner contributed to the sound/oss/esssolol.c and sound/oss/maestro.c drivers. This doesn't prove that they knew of each and every individual contribution, but it shows that they knew contributions were being made and that they were made officially, with Caldera's blessing.
The next question would be: what kind of ... nah, I don't want to tell them. They might rewrite history. I figure by now they probably read Groklaw. I then found a Bradley Kuhn interview, back in May, where he says Caldera assigned copyrights on employee contributions to the FSF: Indeed, FSF holds documents from SCO regarding some of this code. SCO has disclaimed copyright on changes that were submitted and assigned by their employees to key GNU operating system components.
Note he is here talking not about the kernel, judging from the quotation. But it's obvious and I think now settled, that Caldera knew of and approved of its employees contributing to GNU/Linux. There you go, Christoph. In case anybody comes after you.
On the patent front: I found an article in the
Virginia Journal of Law and Technology, written by attorney Rod Dixon, in which he argues that open source code is so vital now that copyright for software code ought to be done away with completely. His view is that most of it doesn't meet the originality requirement, and further that open source makes it possible to quit reinventing the wheel, something proprietary methods doom programmers to have to do over and over, since they can't look at each other's code. The benefit is to society from rapid improvements built into the open source method, in his view, make a complete review of copyright law necessary as it relates to software. Here's part of his conclusion: The DMCA's ostensible approval of locking up access to source code regardless of whether the source code meets the originality requirement may violate copyright's constitutional mandate under circumstances where the technological barrier protects an unoriginal work. It's not an "easy read" by any means, and his view is not mainstream, but it certainly is thorough, with cases and analysis you may find of interest. The actual pdf is here . The article is in Virginia Journal of Law and Technology, Spring 2003, titled, "Breaking into Locked Rooms to Access Computer Source Code: Does the DMCA Violate a Constitutional Mandate When Technological Barriers of Access Are Applied to Software?" by Rod Dixon
8 Va. J.L.& Tech.2 (2003)There is also a New Yorker piece saying patents have gotten out of hand. Here is one snip: The new regime's defenders insist that in today's economy such vigilance is necessary: ideas are the source of our competitive strength. Fair enough. But you don't compete by outlawing your competition.
Want a laugh? Here's an Onion story on MS patenting ones and zeroes. It's dated 1998, so some of you may have seen it already. Nevertheless, it's funnier than ever in the midst of the SCO soap opera.

I've had some email conversations with the OSI about the 1956 AT&T Consent
Decree. They won't or can't admit that two of it's provisions created the
commercial Unix market place, i.e. AT&T was restricted to the common carrier
business - and AT&T had to license it's patents to competitors on resonable and
non-discriminatory terms, e.g. US Patent 3,568,156, entitled "Text Matching
Algorithm," 2 Mar 1971, inventor Ken Thompson; or US Patent 4,135,240 entitled
"Protection of Data File Contents" 16 Jan 1979, inventor Dennis Ritchie. Unix
may never have been declared to be an Essential Public Facility, but that didn't
stop it from being treated exactly like one. If patents and copyrights are just
grants of monopoly power from the government- this consent decree was the
government denying those grants of power to AT&T.
After providing a safe harbor for twenty years, Judge Greene wrote a few pages
of text (the Modified Final Judgement) that simply altered the 1956 decree. It
was only intended to allow AT&T to enter the computer business. It actually gave
them an instant monopoly over all of their Unix competitors works and a whole
generation of CS students who had studied Unix concepts and methods. When AT&T's
attempts at competition proved themselves to be financial disasters they
resorted to the courts instead in USL v BSDI. Novell settled that suit, but
never figured out how to profit from the Unix IP they had purchased either. They
left the business for the same reasons AT&T did. It's not surprising to see that
SCO Group is playing it's monopoly IP card in court.
I find it odd that Intel CPU technology is considered an Essential Public
Facility (Intergraph v Intel), but that neither of the two dominant operating
systems you might need to operate one for desktop or server use are. Both
operating systems were created and controlled by monopolies (or their successors
in interest) that have had multiple consent decress imposed on them - AT&T and
Microsoft. The world is so small, how can it contain this much irony? Harlan[ Reply to This | # ]

Here, take a look at this, something I started a few weeks ago, finally put it
up on the twiki last week.
http:
//twiki.iwethey.org/twiki/bin/view/Main/SCOvsIBMLawEnforcement
And tell me if complaints to the FTC can take advantage of your observations. I
already have a bunch of stuff about attempted monopolization, illegal means of
getting a monopoly
With the addition of what you just wrote it seems like a cut-and-dried extension
of the theory FTC is using in the Rmbs/Unocal cases. Sanjeev[ Reply to This | # ]

There are a number of major differences between this and Rambus. I'm saying that
without the government's 1956 Consent Decree there would never have been an
unfettered market for the supply of Unix operating systems. Can anyone even name
another commercial computer operating system that has been offered by so many
companies on so many hardware platforms? Why are there so many attempts like
Linux the BSD's, OSF/1, or GNU to duplicate Unix with code that isn't encumbered
with any AT&T code? Why are we all re-inventing that same wheel? AT&T was so
constrained by the prohibition against entering new markets outside of their
common carrier business that they sold Unix "as is" without even offering
support, bug fixes, or porting to other hardware platforms. Under those
circumstances something like USENIX and a development community was a practical
necessity. AT&T sold Unix to universities and allowed employees like Ken
Thompson to take sabbaticals where he was teaching it and helping create the BSD
distribution that was given to CS students. AT&T could not refuse to deal with
it's competitiors. It had to license it's patents under reasonable and
non-discriminatory terms. Hundreds of businesses entered the market and hired
the cheap CS Unix talent that the universities were producing.
Here are just a few: Cray,Apollo, DEC, Hewlett-Packard, IBM, Bull, Nixdorf,
Philips, Siemens, Hitachi,Amdahl, Motorola, Novell, Sun Microsystems, ICL Plc.,
Olivetti,Fujitsu Limited, Institute for Information Industry (Taiwan); NEC, OKI,
and Toshiba.
You may have noticed that many of these are still trying to replace encumbered
code with something standard like Linux in their businesses today. At the
slightest hint that AT&T had purchased 20 percent of Sun and was going to do
further development work with them, many of these vendors felt threatened and
founded The Open Software Foundation. It had the goal of creating a Unix
specification and operating system that were free of any AT&T code or IP. Under
the Modified Final Judgement the government simply abandoned it's controls and
left the Unix market that it had created to the mercy of a monopolist. They did
that, even though conduct remedies had failed to curb AT&T's illegal behavior in
the past.
There is our first big problem. Copyright, trademark, and patents are always
government granted monopolies. AT&T couldn't compete on a level playing field.
Everyone familiar with the history recognizes that they weren't playing fair in
the BSDI case. However, without "market power", they looked just like any other
ordinary IP owner excercising their property rights. The government has
conveniently forgotten how we all got on the hook in the first place. If Unix
ever was an Essential Public Facility then it still should be unless something
else has replaced it.
If we look at Judge Nelson's comments in Intergraph v Intel you see the same
things he mentions happening in USL V BSDI or SCO V IBM i.e. increasing returns,
lock-in, monopoly leveraging, coercive reciprocity, unconscionable termination
of access to technical data needed to develop interoperable products, and a host
of other similarities. SCO has sold licenses to everyone that sells a Unix or a
product that uses their API including Sun and Microsoft. They claim that Linux,
the BSDs, OS X, place your ad here, and just about anything else you can think
of might (or definately does) infringe on their "broad rights". That's some
market.
Unfortunately, the FTC or DOJ may challenge the enforcement of invalid
intellectual property rights as antitrust violations, but only when some other
element of an antitrust violation exists. I wish they would use what I call
"Harlan's Rule of Reason". Under my rule attempting to enforce invalid
intellectual property rights is like printing your own money, or impersonating a
police officer. It's prima facia evidence of an antitrust violation because all
IP protections are government granted monopolies and you are using them
wrongfully. Harlan[ Reply to This | # ]
