However,... Larry, just to try to answer the implied question... Remember that the RFC series contains many documents that are not standards, some of which have not significantly passed through the IETF and some of which few people would actual consider implementing -- not because of patent restrictions, but because of what they are. To try to suggest that nothing should be published in the series that has any encumbrances would be a huge step, possibly justified on the basis of a philosophical war on patents, but hard to justify on any other basis -- after all, reading about an encumbered technology for purposes of education, etc., is not an infringement, as others (and I think you) have explained on this list more than once. So the answer to your question is that Experimental RFCs are different from Standards Track ones because, among other things, there is no implicit IETF recommendation of implementation and deployment of the technology and because part of the purpose of publication is educational. In addition, while I take your point that experimental use is infringing (my recollection is that there are some fine points there if the use is strictly to learn about the invention, but you are the expert), no one sane would try to deploy a product strictly on the basis of an Experimental Protocol publication (with or without patent involvement). I would also imagine that, all other things being equal, some people's risk assessment would be different for small-scale experimental uses than for larger-scale product development and deployment. john _______________________________________________ Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
