If technology in this document is included in a standard adopted by IETF and any claims

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

Royalty-bearing licenses will be available to anyone who prefers that option.
