'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):

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

SRI International has filed one or more patents (the "Patents")
protecting the inventions described in its TBRPF submission to the
IETF. If SRI's submission, or material portions thereof, is accepted
and becomes part of an IETF standard (the "Standard"), then SRI will
and hereby does grant any entity wishing to practice the Standard a
non-exclusive, royalty-free license under the Patents to the extent,
but only to the extent, that such license is required to implement (a)
mandatory elements of the Standard; or (b) elements of SRI's submission
that are explicitly specified (and not merely incorporated by
reference) in the Standard. Such license shall automatically become
effective at the time the IETF formally adopts the Standard.

In addition, if any element(s) of SRI's TBRPF submission to the IETF is
included in a standards-track protocol (the "Joint Protocol") that is
developed jointly by SRI and other members of the IETF Mobile Ad-Hoc
Networks working group, SRI will -- whether or not such Joint Protocol
is ultimately adopted as the Standard -- grant any entity wishing to
practice such Joint Protocol a non-exclusive, royalty-free license
under the Patents to incorporate such Joint Protocol into their
research and/or products. Such license shall automatically become
effective at the time any element of SRI's TBRPF submission to the IETF
is included in a standards-track protocol.

Use of any elements of SRI's submission that are neither required in
order to implement the Standard nor explicitly specified in the
Standard will require an additional license from SRI under terms to be
negotiated between the parties.

While the protocol disclosed in SRI's submission is being evaluated by
the IETF or is described in an experimental RFC, whether on the
standards track or otherwise, SRI will and hereby does grant any party
a license to utilize, test and evaluate such protocol for
non-commercial, research purposes.

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.
