Oculus 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 Oculus, to make, have made, use, sell, offer to 
sell, import, and otherwise transfer the Software. For avoidance of doubt, no 
license is granted under Oculus’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.  
 
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 Oculus 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 Oculus 
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 Oculus is invalid or unenforceable.
