I thought in the US one has one year from when one first publishes the idea to seek any patents. More specifically in 35 USC 102 lists the conditions or "barring events" for a patent: http://www4.law.cornell.edu/uscode/35/102.html So if AT&T published a paper a year ago, TMDA used the idea, and then AT&T just submitted a patent then TMDA would not count as prior art. > > What about prior art? Ezmlm was the first place I saw keyed addresses used. I do not know where DJB got the idea from, but he is involved in the crypto community. He may have invented the idea, I do not know. Ezmlm calls them "cookie" addresses. I know I have an ezmlm key file dated August 1, 1999. So I have been using keyed addresses since at least then. I was using ezmlm before that, but I have no idea how long before that and I have no idea when ezmlm started using "cookies". Benjamin J.
