V. Licensing Declaration

The Patent Holder states that its position with respect to licensing any patent claims contained in the patent(s) or patent application(s) disclosed above that would necessarily be infringed by implementation of the technology required by the relevant IETF specification ("Necessary Patent Claims"), for the purpose of implementing such specification, is as follows(select one licensing declaration option only):

See Text Below for Licensing Declaration
Licensing information, comments, notes, or URL for further information

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. Cisco retains the right to assert its patents
against any product or portion thereof that is not necessary for
compliance with the standard.

To maintain reciprocity, notwithstanding anything to the contrary,
Cisco retains the right to assert its patents (including the right to
claim past royalties) against any party that asserts a claim of a
patent it owns or controls (either directly or indirectly), where such
claim is necessary for practicing the standard, 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, where such assertion by such party
is directed against implementation of the standard.

Note: The individual submitting this template represents and warrants that he or she is authorized by the Patent Holder to agree to the above-selected licensing declaration.
