Additional Grant of Patent Rights Version 2 | |
"Software" means the React software distributed by Facebook, Inc. | |
Facebook, Inc. ("Facebook") hereby grants to each recipient of the Software | |
("you") a perpetual, worldwide, royalty-free, non-exclusive, irrevocable | |
(subject to the termination provision below) license under any Necessary | |
Claims, to make, have made, use, sell, offer to sell, import, and otherwise | |
transfer the Software. For avoidance of doubt, no license is granted under | |
Facebook's rights in any patent claims that are infringed by (i) modifications | |
to the Software made by you or any third party or (ii) the Software in | |
combination with any software or other technology. | |
The license granted hereunder will terminate, automatically and without notice, | |
if you (or any of your subsidiaries, corporate affiliates or agents) initiate | |
directly or indirectly, or take a direct financial interest in, any Patent | |
Assertion: (i) against Facebook or any of its subsidiaries or corporate | |
affiliates, (ii) against any party if such Patent Assertion arises in whole or | |
in part from any software, technology, product or service of Facebook or any of | |
its subsidiaries or corporate affiliates, or (iii) against any party relating | |
to the Software. Notwithstanding the foregoing, if Facebook or any of its | |
subsidiaries or corporate affiliates files a lawsuit alleging patent | |
infringement against you in the first instance, and you respond by filing a | |
patent infringement counterclaim in that lawsuit against that party that is | |
unrelated to the Software, the license granted hereunder will not terminate | |
under section (i) of this paragraph due to such counterclaim. | |
A "Necessary Claim" is a claim of a patent owned by Facebook that is | |
necessarily infringed by the Software standing alone. | |
A "Patent Assertion" is any lawsuit or other action alleging direct, indirect, | |
or contributory infringement or inducement to infringe any patent, including a | |
cross-claim or counterclaim. |
