As far as GPL goes, GPLed code can't be distributed if using it would 
violate a patent.  If the patent is held by the author of the code, 
then free use is granted for that code.  A patent held by some other 
party could also block distribution of GPLed code.

For every patent that one becomes aware of, there are another ten 
patents you are not aware of which will be revealed when your market 
share becomes large enough to produce some money.
