Dear IETF, Moved by the FSF's public call, I have read the Fourth Last Call on draft-housley-tls-authz-extns at http://www.ietf.org/mail-archive/web/ietf-announce/current/msg05617.html, and the associated IPR disclosure 1026. As far as I understand those documents, their meaning is that while the standard per se can be implemented without licensing RedPhone Security's patent, such implementations will actually not be interoperable with implementations using patented techniques and formats. In addition, RedPhone's pledge to grant licenses in a 'fair and nondiscriminatory manner' all but makes it certain that some implementors will be forced to due without such licenses, as what is usually considered 'fair' in patent licensing, can be, and usually is, incompatible with Free Software. Accepting the standard will serve only to drive wedges in the Internet, the opposite of the purpose of any standard. It will attempt to marginalize Free Software, which can probably only marginalize the standard itself, or, even, the standards body. Please don't go there. Please don't settle for RAND licensing, and only accept Perpetual Royalty-Free licenses for patents required for implementing standards. Sincerely, Shai Berger. _______________________________________________ Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
