This is exactly what patents are intended to do.  *Identify* and
*publicize* key concepts that would *not* be known to ordinary
practitioners.  Patents are not about rewarding creativity or
breakthrough ideas.  They're about rewarding *innovation*, which means
invention *plus practice*.

The existing patent system fails on the publicization part to date.
Looking around at the various search services now available, however,
I wonder if that is going to be true much longer.

It also creates contradictory incentives concerning innovation.
That's inherent in the kind of monopoly granted.  But that's a
completely different argument from the one you are making.

Emerson applies here: "A foolish consistency is a hobgoblin of little
minds."  As does Professor Bernardo de la Paz: "Revolution is an art I
pursue, not an objective I expect to achieve."

There's no such obligation in the open source community.  That's
precisely Stallman's issue with it.  You can of course impose such an
obligation by using the GPL, but there are alternative licenses,
including copyleft alternatives, that do not.

Tom, you did that work how many years ago?  For shame, not researching
and publishing such a simple thing! :-/

Even more shameful :-, you're not thanking Prof. Cameron for saving
you the few months' effort, which you can now apply to something
else.  Which is *precisely* what the patent system is for.

The *problem* with the patent system is that you might have already
done 5 of 6 months' worth of work.  Then you'd have a complaint,
although the social benefit of the patent system on average might
overrule you.  But the situation you find yourself in is *exactly* the
best possible outcome for the patent system!  You haven't done the
work yet, the technique is published *before* you would (could!) have
published it, and *your valuable time* is freed for other R&D.

Of course you can, as long as your code is not derivative of GPL'ed
code.  AFAIK, you don't have to offer the GPL protections to your
licensees, even though they have to offer them to downstream.  The GPL
you offer simply lays out the restrictions that you put on their
redistribution; it doesn't promise them that there are no third-party
restrictions they must also satisfy.  As far as I can see, you
statisfy the conditions of the covenant, so you run no risk from
International Characters litigation.

BTW, that's why the economics literature calls it a "patent race."
