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 (#1297)This (#1525)
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 the IETF, any entity will have the right to use any claims of any Skype patents that are necessary for practicing the technology to the extent that the technology is included in the standard, under royalty free, reasonable and non discriminatory terms, to implement and fully comply with the standard. These terms shall include: Skype retains the right to terminate any license grants and assert its patents (including the right to claim past royalties) against any entity (including its affiliates) that asserts a patent owned or controlled by it or its affiliates (either directly or indirectly) or that brings any lawsuit against Skype or any of Skype’s affiliates or successors in title; Skype retains the right to assert its patents against any product or portion thereof that is not necessary to comply with the standard; and the entity will agree not to assert any patents that are necessarily infringed by practicing the technology against any other entity practicing the technology, or against Skype or its licensees. A royalty-bearing option will also be available.

Licensing information, comments, notes, or URL for further information

If the technology in this document is included in an audio codec standard adopted by the IETF (“Standard”), Skype will grant a royalty free license to any claims of the disclosed patents that are infringed by a reference implementation of the standard, to any person or entity for using, making, selling, offering for sale, or importing (i) a decoder that fully complies with the Standard (“Compliant Decoder”) or (ii) an encoder that encodes a bit stream that is capable of being decoded by a Compliant Decoder (“Compliant Encoder”). The foregoing license will be limited to those portions of any Compliant Encoder that are used solely to encode a bit stream that can be decoded by a Compliant Decoder, and those portions of any decoder that are used to decode a bit stream that can be encoded by a Compliant Encoder.

Skype will grant the license subject to the licensee undertaking not to assert any patents, against Skype or any third party, that are infringed by any implementation of the Standard or part of the technology included therein, and granting a royalty free license to any such patents to any party implementing the Standard or technology included therein. Skype will retain the right to terminate the license and assert its patents (including the right to claim past royalties) against any licensee that asserts or whose affiliate asserts any patent (either directly or indirectly) against Skype or any of Skype’s affiliates or successors in title. A royalty bearing option will also be available.

Note: The individual submitting this template represents and warrants that he or she is authorized by the Patent Holder to agree to the above-selected licensing declaration.
