Cisco's Statement about IPR claimed in draft-pruss-dhcp-auth-dsl-00.txt
Date: 12 October 2007
From: Rachel Albright<ralbrigh@cisco.com>

Cisco is the owner of US published patent applications 20070204330, 20070203990, 
and 20070203999 relating to the subject matter of "Authentication Extensions for 
the Dynamic Host Configuration Protocol" <draft-pruss-dhcp-auth-dsl-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.
