Title: Juniper's Statement of IPR related to RFC 4951 Date: February 9, 2009 Submitter: Heidi Woods Juniper is the owner of US Patent Application Serial No(s). 10/997,470 (and any foreign counterparts) relating to the subject matter of "Fail Over Extensions for Layer 2 Tunneling Protocol (L2TP) "failover"" . If technology in this document is included in a standard adopted by IETF and any claims of any Juniper 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, Juniper will not assert any patents owned or controlled by Juniper against any party for making, using, selling, importing or offering for sale a product that implements the standard, provided, however that Juniper 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 Juniper or any of Juniper's affiliates or successors in title or against any products of Juniper or any products of any of Juniper's affiliates either alone or in combination with other products; and Juniper 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.
