     6  Google hereby grants to You a perpetual, worldwide, non-exclusive,
     7  no-charge, royalty-free, irrevocable (except as stated in this section)
     8  patent license to make, have made, use, offer to sell, sell, import,
     9  transfer and otherwise run, modify and propagate the contents of this
    10  implementation of Go, where such license applies only to those patent
    11  claims, both currently owned or controlled by Google and acquired in
    12  the future, licensable by Google that are necessarily infringed by this
    13  implementation of Go.  This grant does not include claims that would be
    14  infringed only as a consequence of further modification of this
    15  implementation.  If you or your agent or exclusive licensee institute or
    16  order or agree to the institution of patent litigation against any
    17  entity (including a cross-claim or counterclaim in a lawsuit) alleging
    18  that this implementation of Go or any code incorporated within this
    19  implementation of Go constitutes direct or contributory patent
    20  infringement, or inducement of patent infringement, then any patent
    21  rights granted to you under this License for this implementation of Go
    22  shall terminate as of the date such litigation is filed.
