-Additional Grant of Patent Rights Version 2
-
-"Software" means the FBMarkdown software contributed 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.
