Cisco's Statement about IPR claimed in draft-sgundave-mip6-proxymip6
Date: 28 February 2007 
From: Rachel Albright 

Cisco was notified on February 6, 2007, that the IETF had received a
Third-Party IPR Disclosure (see
ip6.txt) relating to the IETF document entitled "Proxy Mobile IPv6"
 and Cisco's US Patent Nos. 6,795,857 and
6,982,967 and published patent applications US20040114559,
US20040213260, and EP1618723.

If technology in this IETF 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
