I oppose the publication of "Transport Layer Security (TLS) Authorization Extensions" (draft-housley-tls-authz-extns) due to patent restrictions on the use of these extensions. The implementation appears to be released from any potential patent claims for implementing the protocol(s) as described in draft-housley-tls-authz-extns-07.txt Yet the release of IPR for implementation is followed by patent claims as to the use of part or all of those implementations. This puts the IETF in the position of approving for use a protocol standard whose implementation is unimpeded but whose actual use incurs potential risk to users of AUTHZ protocol extension implementations. The language stating that "RedPhone Security agrees to grant licenses for such uses in a fair and non-discriminatory manner" does not explicitly or implicitly indicate that such grants would be royalty-free or free of other charges or limitations by RedPhone Security. In essence, a private company with patented IPR is proposing a protocol standard that, if adopted by the IETF, may well lead to IPR lawsuits against those using such implementations. This is neither in the intent nor spirit of Internet protocols nor in the best interests of the public at large. As such this draft standard must be rejected by the IETF until RedPhone Security releases all IPR with respect to the implementation and use of the AUTHZ extensions protocol or submits to granting a royalty-free license to implement and use the protocol extensions.
