Only if you're using someone else's patented algorithm inappropriately.  My
code had IDEA (for PGP 2.x support) in it, I included Ascom Tech's patent
statement in the docs as they requested giving the T&C under which it could be
used, and sent them a courtesy note about it.  I got a reply from them that
said something like "thanks for the note, and all the best with your work". So
provided you play by the rules (whether you agree with them or not), things
should be OK.

Peter.
