INTRODUCTION
Google Inc. acquired Global IP Solutions, Inc. (GIPS) in 2011, and GIPS is now a
subsidiary of Google. Google Inc. and its subsidiaries and affiliates ("Google")
would like to update and clarify their position with respect to any patents and
patent applications it may own that cover the iLBC (internet low bit-rate) codec
technology that is the subject of IETF RFC 3951 and RFC 3952. This notice is
provided in accordance with RFC 3979 and RFC 4879 covering IPR in the IETF.
DECLARATION
"iLBC Specification" means IETF RFC 3951 and RFC 3952.
Google hereby grants to you a perpetual, worldwide, non-exclusive, no-charge,
irrevocable (except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, transfer, and otherwise run, modify and
propagate implementations of the iLBC Specification, where such license applies
only to those patent claims, both currently owned by Google and acquired in the
future, licensable by Google that must necessarily be infringed because of what
is specifically required by the normative portions of the iLBC Specification.
This license is offered on the condition that you grant a reciprocal license
under the same terms as this license to all parties for implementations of the
iLBC Specification under those patent claims, both currently owned by you and
acquired in the future, licensable by you that must necessarily be infringed
because of what is specifically required by the normative portions of the iLBC
Specification. If you or your agent or exclusive licensee institute or order or
agree to the institution of patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that any implementation of the
iLBC Specification constitutes direct or contributory patent infringement, or
inducement of patent infringement, then any patent rights granted to you under
this license shall terminate as of the date such litigation is filed.
In addition to the license above relating to what is required by the specification,
the following license relating to the reference implementation is offered.
"The iLBC reference implementation" means the c-code reference implementation in
Appendix A of IETF RFC 3951.
Google hereby grants to you a perpetual, worldwide, non-exclusive, no-charge,
irrevocable (except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, transfer, and otherwise run, modify and propagate
the iLBC reference implementation, where such license applies only to those patent
claims, both currently owned by Google and acquired in the future, licensable by
Google that are necessarily infringed by the iLBC reference implementation. This
grant does not include claims that would be infringed only as a consequence of
further modification of the iLBC reference implementation. If you or your agent or
exclusive licensee institute or order or agree to the institution of patent
litigation against any entity (including a cross-claim or counterclaim in a
lawsuit) alleging that the iLBC reference implementation constitutes direct or
contributory patent infringement, or inducement of patent infringement, then any
patent rights granted to you under this License shall terminate as of the date such
litigation is filed.
