Larry Sorry that I answered before seeing that others had already said the same thing. However, even after reading your subsequent email, I am unconvinced. Requesting a re-examination is a lengthy process, and if unsuccessful further strengthens the party holding the patent (as it has gone through 2 examinations). On the other hand, the patent holder can force you to respond in a Texas court within 30 days, incurring the costs of representation. BTW, this kind of patent busting is hardly new. There used to be a "patent busters" site where bounties were offered. Y(J)S _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
