Title: Cisco System's Statement About IPR Claimed in draft-gurbani-soc-overload-control-01.txt
Date: 2010-07-22

Cisco is the owner of US Patent No. 7,760,639 relating to the subject matter of "Session 
Initiation Protocol (SIP) Overload Control" <draft-gurbani-soc-overload-control-01>. 

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.
