Cisco's Statement about IPR claimed in RFC 3963
Date: 10 April 2006 
From: Dan Lang<dlang@cisco.com>

Cisco is the owner of US Patent No. 6636498 and one or more pending 
unpublished patent applications relating to the subject matter of Request 
for Comments (RFC) 3963, entitled "Network Mobility (NEMO) Basic Support 
Protocol."

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; 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.
