Additional Grant of Patent Rights

Additional Grant of Patent Rights Version 2

"Software" means the React software distributed by Facebook, Inc.

Facebook hereby grants you a perpetual, worldwide, royalty-free, non-exclusive,

irrevocable (subject to the termination provision below) license under any

rights in any patent claims owned by Facebook, 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 a third party,

or (ii) the Software in combination with any software or other technology

provided by you or a third party.

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,

for anyone that makes any claim (including by filing any lawsuit, assertion or

other action) alleging (a) direct, indirect, or contributory infringement or

inducement to infringe any patent: (i) by Facebook or any of its subsidiaries or

affiliates, whether or not such claim is related to the Software, (ii) by any

party if such claim arises in whole or in part from any software, product or

service of Facebook or any of its subsidiaries or affiliates, whether or not

such claim is related to the Software, or (iii) by any party relating to the

Software; or (b) that any right in any patent claim of Facebook is invalid or

unenforceable.

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.
