| Additional IP Rights Grant (Patents) | |
| "This implementation" means the copyrightable works distributed by | |
| Google as part of this crate | |
| 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 this 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 | |
| this implementation. 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 or any other | |
| patent enforcement activity against any entity (including a | |
| cross-claim or counterclaim in a lawsuit) alleging that this | |
| implementation constitutes direct or contributory patent | |
| infringement, or inducement of patent infringement, then any patent | |
| rights granted to you under this License for this implementation | |
| shall terminate as of the date such litigation is filed. |
