Licensing
See Text Below for Licensing Declaration
Licensing information, comments, notes, or URL for further information

Apple Inc. (“Apple”) has one or more pending unpublished patent applications ("Subject Patents") that
include one or more claims that Apple believes may be essential for implementing technology set forth
in Informational Internet Draft “Making Multipath TCP robust for stateless web servers” dated
April 27, 2015 <draft-paasch-mptcp-syncookies-00>. 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:

If the Standard is adopted by 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 licenses 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.
