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.
