Cisco's Statement about IPR claimed in draft-charny-pcn-single-marking-00.txt
Date: 21 December 2006
From: Rachel Albright<[email protected]>

Cisco is the owner of one or more pending unpublished patent applications
relating to the subject matter of "Pre-Congestion Notification Using Single
Marking for Admission and Pre-emption" <draft-charny-pcn-single-marking-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 have the right 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 or
against any products of Cisco or any products of any of Cisco's affiliates either
alone or in combination with other products; 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.
