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
