From: "Matthew James Gering" <mgering@ricochet.net> To: <cryptography@c2.net> Date: Wed, 16 Jul 1997 15:44:30 -0700 Would someone have to sue RSA and/or the US PTO in order to invalidate the patent, or would they have to violate the patent and sucessfully defend themselves? I've often wondered why it hasn't been done already.
