     Additional IP Rights Grant (Patents)
     ------------------------------------

     &quot;These implementations&quot; means the copyrightable works that implement the WebM
     codecs distributed by Google as part of the WebM Project.

     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
     implementations. If you or your agent or exclusive licensee institute or order
     or agree to the institution of patent litigation or any other patent
     enforcement activity against any entity (including a cross-claim or
     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.
