Cisco's Statement about IPR Claimed in draft-sajassi-l2vpn-pbb-vpls-cmac-flush-00.txt
Date: 5 August 2008 
From: 	Rachel Albright<ralbrigh@cisco.com>

Cisco is the owner of US Patent Application Serial No. 11/948,405 relating to the 
subject matter of "Customer MAC Address Flushing Mechanisms for Provider Backbone 
Bridging over VPLS" <draft-sajassi-l2vpn-pbb-vpls-cmac-flush-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.
