Dear IETF: There appears to be a show-stopper in draft-housley-tls-authz-extns-07.txt https://datatracker.ietf.org/idtracker/ballot/2081/ It appears that the proposed standard is patent-encumbered. 1) This violates the EU definition of open standard 2) It hinders, and in some cases, prevents *use*, and use is what standards are about. So as such it threatens to impair e-commerce and general web security 3) It puts the IETF in a bad light to have allowed an apparently patent encumbered payload to get so far along in the standards discussion The solution is to remove any items claimed to be patented, or else follow the EU's requirements for open standard and put in writing that there are no constraints on re-use. Grant the copyright and patents irrevocably, royalty-free for implementation, use and distribution.
