Dear IETF committee members, In February 2006, a standard for "TLS authorization" was introduced in the IETF for consideration. Very late in the discussion, a company called RedPhone Security disclosed (this disclosure has subsequently been unpublished from the IETF website) that they applied for a patent which would need to be licensed to anyone wanting to practice the standard. After this disclosure, the proposal was rejected. Despite claims that RedPhone have offered a license for implementation of this protocol, users of this protocol would still be threatened by the patent. The IETF should continue to oppose this standard until RedPhone provide a royalty-free license for all users. Sincerely yours, ------------------------------------------- Pedro J.
