| Additional Grant of Patent Rights Version 2
 | |
| 
 | |
| "Software" means the Zstandard 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.
