------- begin appended copy of letter Hi Zooko, I tried following up to cryptography@randombit.net but haven't taken the time to figure out which hoops to jump through to make messages actually appear there. Anyway, you have to read the "parent case" section of the patent: This is a continuation of PCT/CA95/00452, filed on Jul. 31, 1995, which is a continuation-in-part of Ser. No. 08/282,263, filed on Jul. 29, 1994, now abandoned. This means that the patent can survive prior art after July 1993, but it also means that the patent expires in 2014. ---Dan _______________________________________________ cryptography mailing list cryptography@randombit.net http://lists.randombit.net/mailman/listinfo/cryptography
