No, it's not. Prior art doesn't mean "an example of something having
been done before". The question to ask is, "Given the claim in this
patent, would it be obvious to a skilled software engineer how to
implement it?". "Obvious" is generally taken to mean that the idea, or
some close parallel, has been published.

No, you're not comparing like with like. Linux is Free Software. If you
accept that source code is speech (which is what makes this arguable),
having the code around is essentially equivilent to publishing. It's a
reference work, if you like. SunOS is proprietary software; it is most
definitely not a published work (not counting the current SCSL or
whatever release, since we're talking 1993). How it works internally is
a trade secret almost, you can't argue that it has contributed to the
art. Sun's implementation of raw network access will help no-one except

Rubbish. We're not talking about copying ideas, we're talking about what
is obvious. Obvious means "yes, I know how to do that", not "give me 18
months of research and I should be able to do it". I would suggest that
many features "copied" from Sun, patented or not, would have taken
considerable time to research and implement, and would not have been

I wasn't even aware of them, so it's unlikely that I regret the fact
that they are available. If you can find an RFC on raw network access
describing the internals of SunOS dated before 1993, then you probably
have prior art.
Don't turn this into a Sun vs. Linux argument again please, we've had
enough of that...
