("Facebook") hereby grants to each recipient of the Software 6("you") a perpetual, worldwide, royalty-free, non-exclusive, irrevocable 7(subject to the termination provision below) license under any Necessary 8Claims, to make, have made, use, sell, offer to sell, import, and otherwise 9transfer the Software. For avoidance of doubt, no license is granted under 10Facebook’s rights in any patent claims that are infringed by (i) modifications 11to the Software made by you or any third party or (ii) the Software in 12combination with any software or other technology. 13 14The license granted hereunder will terminate, automatically and without notice, 15if you (or any of your subsidiaries, corporate affiliates or agents) initiate 16directly or indirectly, or take a direct financial interest in, any Patent 17Assertion: (i) against Facebook or any of its subsidiaries or corporate 18affiliates, (ii) against any party if such Patent Assertion arises in whole or 19in part from any software, technology, product or service of Facebook or any of 20its subsidiaries or corporate affiliates, or (iii) against any party relating 21to the Software. Notwithstanding the foregoing, if Facebook or any of its 22subsidiaries or corporate affiliates files a lawsuit alleging patent 23infringement against you in the first instance, and you respond by filing a 24patent infringement counterclaim in that lawsuit against that party that is 25unrelated to the Software, the license granted hereunder will not terminate 26under section (i) of this paragraph due to such counterclaim. 27 28A "Necessary Claim" is a claim of a patent owned by Facebook that is 29necessarily infringed by the Software standing alone. 30 31A "Patent Assertion" is any lawsuit or other action alleging direct, indirect, 32or contributory infringement or inducement to infringe any patent, including a 33cross-claim or counterclaim. 34
