Most cryptographic algorithms which can be used with OpenPGP infringe some patents in some countries (except RSA in the US, where the patent has expired last year, and Rijndeal/AES). Fortunately, only the IDEA patent seems to be enforced actively, so GnuPG provides most (if not all) OpenPGP algorithms except IDEA.
