Howdy all,
Over on the IETF discussion list, I've been asked to "present evidence" about the patent-encumbered status of the technology in 'draft-housley-tls-authz-extns'.
I don't have that information to hand, and am not sure where to look. Can anyone help?
As far as I know, there is only a patent application at this time, but it is likely to be published as a patent eventually. The author's company was founded in 2005. I'm not sure what "patent enforcement" means in practice. In any case, I'm not aware of any lawsuits from them, but I haven't looked. They have been trying to get GnuTLS to sign their patent license though.

I'm aware of evidence that a party has claimed to have patents that cover the technology. That's significantly weaker than your claim 1.

Thanks. Can you point us to information about the specific patent application?

I don't suppose any of this is online where I can point others to it?

It is mentioned in the IETF IPR notification:
https://datatracker.ietf.org/ipr/912/ https://datatracker.ietf.org/public/ipr_detail_show.cgi?ipr_id=833
It seems down now though... searching for the patent number given in that notification should work.

Some of it is available on the ietf@ietf.org list, but I think the specific requests were in private emails. The license is available directly from them:

Since I wouldn't be able to sign anything on behalf of GnuTLS or the FSF anyway, I asked them to talk to the FSF instead.
