Cisco's Statement about IPR claimed in draft-ietf-pce-path-key-00.txt
Date: 7 August 2007
From: Rachel Albright<[email protected]>

Cisco is the owner of US published patent application 20060098657 relating to the
subject matter of "Preserving Topology Confidentiality in Inter-Domain Path Computation
using a key based mechanism" <draft-ietf-pce-path-key-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.
