(a) Authority and responsibility. Acknowledgments and oaths required in connection with applications for registration of trademarks may be made, in a foreign country, before any diplomatic or consular officer of the United States or before any official authorized to administer oaths in the foreign country whose authority must be proved by a certificate of a diplomatic or consular officer of the United States (15 U.S.C. 1061). The responsibility of officers of the Foreign Service in this connection is the same as that where notarial services in connection with patent applications are involved (see § 92.72(a)). (See § 92.72(c) regarding the authentication of the authority of a foreign official who performs a notarial service in connection with a patent application.)

(b) Fees. The fee for administering an oath, taking an acknowledgment, or supplying an authentication, in connection with an application for registration of a trademark, or with the assignment or transfer of rights thereunder, is as prescribed in item 49 of the Tariff of Fees, Foreign Service of the United States of America (§ 22.1 of this chapter).
