 Google hereby grants to you a perpetual, worldwide, non-exclusive, no-charge,
 royalty-free, 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 these implementations of WebM, 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 these implementations of WebM. This grant does not include claims
 that would be infringed only as a consequence of further modification of these

 or agree to the institution of patent litigation or any other patent

 counterclaim in a lawsuit) alleging that any of these implementations of WebM
 or any code incorporated within any of these implementations of WebM
 constitute direct or contributory patent infringement, or inducement of
 patent infringement, then any patent rights granted to you under this License
 for these implementations of WebM shall terminate as of the date such
 litigation is filed.
