There is a difference (that I should have put in my previous email) between a 
patented protocol and a dissector that requires patented material.

So if the patented part was in producing a particular datagram, but there was 
no patent on decoding it, then there is no conflict. Or perhaps we can do 
part of it - the laplink protocol that I'm decoding has a patented 
compression scheme (with clear, patented prior art and probably some other 
prior art, mind you). I just plan on flagging that content, not decoding it.
