IV. Disclosure of Patent Information i.e., patents or patent applications required to be disclosed by Section 6 of RFC 3979

A. For granted patents or published pending patent applications, please provide the following information:

Patent, Serial, Publication, Registration, or Application/File number(s)

No idea. See http://www.microsoft.com/openspecifications/en/us/programs/osp/security/default.aspx and https://datatracker.ietf.org/ipr/434/
Date: 2006
Country: US

Notes: See http://www.microsoft.com/openspecifications/en/us/programs/osp/security/default.aspx and https://datatracker.ietf.org/ipr/434/.

Note that the form insisted I fill in the above; I have no idea whether any of it is right. Please see the links for the information I have.

I think Microsoft registered their IPR against MARID forms of the I-Ds, and the ones that were published were not those.

B. Does this disclosure relate to an unpublished pending patent application?:

Has patent pending
