Cisco's Statement about IPR claimed in draft-baker-sava-implementation-00
Date: 4 December 2007 
From: Mary Shannon<mashanno@cisco.com>

Cisco is the owner of US Patent Application Serial Numbers 10/654,388 and 
10/971,523 relating to the subject matter of "Source address validation in 
the local environment" <draft-baker-sava-implementation-00>.

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.
