Patents don't always require licensing. Ever Unix system extant
has a patented piece in it [or perhaps HAD is more appropriate]
as the patents had expired.
I saw the copy of it years ago and I looked for it recently but
can't figure out where it is.

The key thing with patents is that they are meaningless until the
patent holder decides to protect them in court by challenging the
people who are supposedly in violation of the patent. If a patent
holder decides to go after you, it can be costly even if you win.
They can't
This whole thread is kind of silly. Don't people realize the sheer
number of patent infringments there are in FreeBSD (or, indeed,
Linux?) Sure, you could add a flag to turn each and every instance of
such patent infringment off but the end-result would be something that
didn't even resemble an

So it looks like we have prior art by around 6 years, which would
invalidate the patent iff it was the same thing.
