 | "This implementation" means the copyrightable works distributed by | 
 | Google as part of the Fuchsia 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 this implementation of Fuchsia, 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 of Fuchsia 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 | 
 | Fuchsia shall terminate as of the date such litigation is filed. |
