Additional Grant of Patent Rights Version 2
2+
3+
"Software" means the FBX2glTF software contributed by Facebook, Inc.
4+
5+
Facebook, Inc. ("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
8+
Claims, to make, have made, use, sell, offer to sell, import, and otherwise
9+
transfer the Software. For avoidance of doubt, no license is granted under
10+
Facebook’s rights in any patent claims that are infringed by (i) modifications
11+
to the Software made by you or any third party or (ii) the Software in
12+
combination with any software or other technology.
13+
14+
The license granted hereunder will terminate, automatically and without notice,
15+
if you (or any of your subsidiaries, corporate affiliates or agents) initiate
16+
directly or indirectly, or take a direct financial interest in, any Patent
17+
Assertion: (i) against Facebook or any of its subsidiaries or corporate
18+
affiliates, (ii) against any party if such Patent Assertion arises in whole or
19+
in part from any software, technology, product or service of Facebook or any of
20+
its subsidiaries or corporate affiliates, or (iii) against any party relating
21+
to the Software. Notwithstanding the foregoing, if Facebook or any of its
22+
subsidiaries or corporate affiliates files a lawsuit alleging patent
23+
infringement against you in the first instance, and you respond by filing a
24+
patent infringement counterclaim in that lawsuit against that party that is
25+
unrelated to the Software, the license granted hereunder will not terminate
26+
under section (i) of this paragraph due to such counterclaim.
27+
28+
A "Necessary Claim" is a claim of a patent owned by Facebook that is
29+
necessarily infringed by the Software standing alone.
30+
31+
A "Patent Assertion" is any lawsuit or other action alleging direct, indirect,
32+
or contributory infringement or inducement to infringe any patent, including a
33+
cross-claim or counterclaim.
