VI. Licensing Declaration

The Patent Holder states that its position with respect to licensing any patent claims contained in the patent(s) or patent application(s) disclosed above that would necessarily be infringed by implementation of the technology required by the relevant IETF specification ("Necessary Patent Claims"), for the purpose of implementing such specification, is as follows(select one licensing declaration option only):

Previous (#1447) This (#1526)
See Text Below for Licensing Declaration Licensing See Text Below for Licensing Declaration

If the technology in this document is included in a standard adopted by IETF ("the Standard") and any claims of the disclosed patent applications become Necessary Patent Claims for practicing the Standard, Broadcom will not assert any such patent claims (“Subject Claims”) against any party for making, using, selling, importing or offering for sale a product that implements and fully complies with the Standard, provided, however, that Broadcom retains the right to assert the Subject Claims (including the right to claim past royalties) against any party that asserts a patent it owns or controls (either directly or indirectly), where such patent relates to codec technology, against Broadcom or any of Broadcom's affiliates or successors in title, or against any products of Broadcom or products of any of Broadcom’s affiliates either alone or in combination with other products. Broadcom retains the right to assert the Subject Claims against any product or portion thereof that is not necessary for compliance with the Standard.

VIII. Other Notes

Additional notes

License Grant. Broadcom Corporation (“Broadcom”) 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 Broadcom or acquired hereafter
that Broadcom 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.
