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

Apple Inc. ("Apple") is the owner of the unpublished application referred to herein (Subject Application) relating to the subject matter in the Internet Draft "Hybrid Unicast/Multicast DNS-Based Service Discovery" dated January 26, 2013 <draft-cheshire-mdnsext-hybrid-01>. If technology in this document is included in a standard adopted by the IETF ("the Standard") and any claims of the Subject Application are necessary for practicing the Standard, any party will have the right to use any such patent claims ("Subject Claims") under reasonable, nondiscriminatory terms, with reciprocity, to implement and fully comply with the Standard.

The reasonable, non-discriminatory terms are:

If the Standard is adopted by the IETF, Apple will not assert the 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 Apple 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) against Apple or any of Apple's affiliates or successors in title; and Apple retains the right to assert the Subject Claims against any product or portion thereof that is not necessary for compliance with the Standard.

Royalty-bearing license will be available to anyone who prefers that option.

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.
