IV. Disclosure of Patent Information
i.e., patents or patent applications required to be disclosed by 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)

EP97103790, US6,163,844
Date: march 06, 1997
Country: Germany

Notes: I was an inventor. The Siemens subsidiary involved no longer
exists. I don't know where the ownership ended up.
The filing is extremely unclear, even for a patent - the reason is that
the lawyer translated my input to German, filed that and later translated
back to English, all without checking back with any of the inventors.
The German version may be more easily understood, I don't know.
The original filing was to protect a product that sent SESAME PACs (inside
GSS tokens) to & fro in order to do access control for web clients &
servers. The I-D isn't doing that, but the claims might be written
broadly enough to be a concern.

B. Does this disclosure relate to an unpublished pending patent application?:

Has patent pending No
