Hello! I'm writing in because I've been made aware that the IETF is considering a standard (currently called "TLS authorization") that would be encumbered by a patent. In this case, that patent is held by a company called RedPhone. I have held the IETF and its work in the highest esteem over the years. I hope that you will not jeopardize your stature and relevance by approving a standard that is encumbered by a patent. Patent-encumbered standards hurt those both inside and outside of the technology industry. I hope it is obvious that a standard, especially for a communications protocol, can't be beneficial if it cannot be widely implemented, by organizations large and small, by individuals, and by free and open source software developers (whose work powers so much of the internet's infrastructure). I hope you will continue to oppose this standard until RedPhone provides a royalty-free license for all users.
