| "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. |
