Cisco's Statement about IPR claimed in draft-ietf-dhc-subnet-alloc-04.txt
Date: 27 February 2007 
From: Rachel Albright<ralbrigh@cisco.com>

Cisco is the owner of US Patent No. 7,051,089 relating to the subject matter 
of "Subnet Allocation Option" <draft-ietf-dhc-subnet-alloc-04.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.
