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.
