Title:  Cisco's Statement of IPR related to RFC 5107
Date:  Tuesday, June 30th 2009
Submitter:  Rachel Albright

Cisco is the owner of US Patent No. 7,139,818 relating to the subject matter of Request for Comments (RFC)
 5107 "DHCP Server Identifier Override Suboption".

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.
