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

Yahoo! is the owner of the Subject Patents listed below relating to the subject matter in the Internet Calendar Scheduling Protocol (iSchedule) https://datatracker.ietf.org/doc/draft-desruisseaux-ischedule/. If technology in this document is included in a standard adopted by IETF ("the Standard") and any claims of the Subject Patents are necessary for practicing the Standard, any party will have the right to use any such patent claims (“Subject Claims”) under reasonable, non-discriminatory terms, with reciprocity, to implement and fully comply with the Standard.

The reasonable, non-discriminatory terms are:
In the event that the Standard is adopted by IETF, Yahoo! 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 Yahoo! 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 Yahoo or any of Yahoo's affiliates or successors in title; and Yahoo 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 licenses will be available to anyone who prefers that option.

“Subject Patents/Applications” means US Patents 6,986,049 and 7,313,700
