License Grant. Xiph.Org Foundation (“Xiph”) hereby grants to you a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable (except as stated in this license) license under Licensed Patents to make, have made, use, offer to sell, sell, import, transfer, and otherwise run, modify (in a way that still complies with the Specification), and reproduce any Implementation.
Definitions. Specification means, and includes the following, both individually and collectively, (a) any standard specification of the Opus codec adopted by the IETF Codec Working Group (“Standard”) and (b) any reference implementation (each, a “Reference Implementation”) published by the IETF Codec Working Group in the request for comments (“RFC”) issued by the IETF for the Specification draft for which this License is issued, or any RFC that is issued as an update or new version thereof. An Implementation means any Reference Implementation, or another implementation that complies with the Specification. Licensed Patents means all patents currently owned by Xiph or acquired hereafter that Xiph has the right to license as set forth above and that are necessarily infringed by the Specification, where “necessarily infringed” means: in the case of (a) above, there is no commercially viable means of implementing the Specification without infringing such patent; in the case of (b) above, use of the reference implementation to the extent it infringes such patent.
Termination. If you, directly or indirectly via controlled affiliate or subsidiary, agent, or exclusive licensee, file a Claim for patent infringement against any entity alleging that an Implementation in whole or in part constitutes direct or contributory patent infringement, or inducement of patent infringement (a “Claim”), provided that a Reference Implementation also infringes the patents asserted in the Claim, then any patent rights granted to you under this License shall automatically terminate retroactively as of the date you first received the grant. Claims made against an Implementation in part will only trigger termination if the Implementation in part was done for the purpose of combining it with other technology that complies with the Specification so that the technology’s ultimate use will be consistent with the Standard as a whole.
