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, and otherwise

where such license applies only to those
patent claims licensable
by such Contributor that are necessarily
infringed by their
Contribution(s) alone or by combination of
their Contribution(s)
with the Work to which such Contribution(s)

institute patent litigation against any entity
(including a
cross-claim or counterclaim in a lawsuit)
alleging that the Work
or a Contribution incorporated within the Work
constitutes direct
or contributory patent infringement, then any
patent licenses
granted to You under this License for that
Work shall terminate
as of the date such litigation is filed.
