Holders of essential patents must submit letters of assurance during the standards development process. Copies of those letters are posted below.
The user’s attention is called to the possibility that compliance with these standards may require use of an invention covered by patent rights.
By publication of these standards, no position is taken with respect to the validity of any such claim(s) or of any patent rights in connection therewith. If a patent holder has filed a statement of willingness to grant a license under these rights on reasonable and nondiscriminatory terms and conditions to applicants desiring to obtain such a license, then details may be obtained from the standards developer.
