I mentioned before that I have a copy of a public key cryptosystem
using RSA that has been released in the public domain. So how is
this effected? One possible point is that the person who wrote it
lives in Canada. Does this mean he doesn't have to abide by US
Patents? How about importing such a thing into the US? Maybe the
guy is just not aware that it is patented and should be notified?
