Dear Msr DE FURST

I note your filing of an IPR claim against the HTTP Digest
Authentication method described in RFC 4768 and RFC 2069.

I note further that the claim is made in respect of a patent
application made in 2008 whereas RFC 2069 was published in 1997 and
the original proposal on which it was based was published by myself on
the www-talk mailing list in 1993.

In what imaginable universe could you possibly conceive that a patent
application made in 2008 would establish a proprietary claim over
prior art published as an international standard fifteen years prior?

The purpose of an IPR filing is to declare an interest in an existing
specification. It is not for soliciting interest in the addition of
features to support a subsequent invention.

Further, I believe that if your clients were to fully consider their
proposed realization that it is in any case anticipated in United
States Patent Application	20050021982, to which an offer of
Royalty-Free Reasonable and Non-Discriminatory licensing for
implementation in RFC 4226 is already on file:

https://datatracker.ietf.org/ipr/1104/


I am Sir, yours etc,

Phillip Hallam-Baker
