What I've never been able to figure out...

Legalese used in patents? I thought patents must be written to be understandable to a person who understands the subject. Doesn't some law say so?

But maybe the art in ordinary skill in the art refers to the art of writing patents. Because the few patents that I've seen are not written in a language that either programmers or computer scientists use to discuss their art.

The patent means whatever the plaintiff's lawyer needs it to
mean at any given point in time.

The patent is supposed to fully disclose.

I gather though, that the application can change over time and in an
insignificant way.

Does the invention of an electrical transformer become invalidated because
"the ground" ceases to be "the ground"? Like when it is on a
boat?

Agreed. I have provided ideas to my employer that they gleefully announced were patentable. Soon after, a lawyer calls and asks questions like:
  • Did you really mean 'table' or would this work on any flat surface?
  • You mentioned 'every 5 seconds' but really, didn't you mean 'at a fixed interval'? For that matter, does it need to be fixed? What if it were dynamic?
  • You mention a diagnostic device, but really, it could be any device with these capabilities, right?

It's the lawyer's job to expand the idea you presented as broadly as possible, because that provides maximum value to the company. In addition, if they need to yield during prosecution, they now have room to do that.

All the attention was flattering at the time, but having seen patents from both sides now, I don't like the sausage that comes out the other end.

who defends the patent?

From what I recall, if a patent is challenged,
the person listed as the inventor has to defend it.
