[vorbis-dev] patents

[Robert M. Bultman]

Same company or a different company, published or not.  One use of
discussing
prior art is to say in effect, "Here is what all of these other people
have done.
Here is where we are doing it differently.  See, it is novel and
different and
therefore deserving of a patent."  People have cited the Amazon (?)
1-click patent
and how someone else got around the patent by using 2-click ordering. 
The 2-click
patent, if it exists, probably lists the Amazon patent as prior art,
then goes to
show how it uses 2-clicks for ordering.  You probably get the picture.
