WebRTC Additional IP Rights Grant
Additional IP Rights Grant (Patents)
"This implementation" means the copyrightable works distributed by
Google as part of the WebRTC code package.
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 contents of this
implementation of the WebRTC code package, 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 this implementation of the WebRTC code package. This
grant does not include claims that would be infringed only as a
consequence of further modification of this 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 this
implementation of the WebRTC code package or any code incorporated
within this implementation of the WebRTC code package constitutes
direct or contributory patent infringement, or inducement of patent
infringement, then any patent rights granted to you under this License
for this implementation of the WebRTC code package shall terminate as
of the date such litigation is filed.
