Title: Cisco's Statement about IPR Claimed in draft-fenton-identified-mail-00.txt
Received: 14 June 2004
From: Robert Barr <rbarr@cisco.com>

Cisco is the owner of one or more pending patent applications relating to
the subject matter of " Identified Internet Mail " <draft-fenton-identified-mail-00.txt>.
If technology in this document is included in a standard adopted by IETF and
any claims of any Cisco patents are necessary for practicing the standard, any party will be
able to obtain a license from Cisco to use any such patent claims under reasonable,
non-discriminatory terms, with reciprocity, to implement and fully comply with the standard.

The reasonable non-discriminatory terms are:

If this standard is adopted, Cisco will not assert any patents owned or
controlled by Cisco against any party for making, using, selling, importing
or offering for sale a product that implements the standard, provided,
however that Cisco retains the right to assert its patents (including the
right to claim past royalties) against any party that asserts a patent it
owns or controls (either directly or indirectly) against Cisco or any of
Cisco's affiliates or successors in title; and Cisco retains the right to
assert
its patents against any product or portion thereof that is not necessary for

compliance with the standard.

Royalty-bearing licenses will be available to anyone who prefers that
option.
