(d) Verified statement that trademark is used in commerce 

(1) Within six months after the date on which the notice of allowance with respect to a mark is issued under section 1063 (b)(2) of this title to an applicant under subsection (b) of this section, the applicant shall file in the Patent and Trademark Office, together with such number of specimens or facsimiles of the mark as used in commerce as may be required by the Director and payment of the prescribed fee, a verified statement that the mark is in use in commerce and specifying the date of the applicants first use of the mark in commerce and those goods or services specified in the notice of allowance on or in connection with which the mark is used in commerce. Subject to examination and acceptance of the statement of use, the mark shall be registered in the Patent and Trademark Office, a certificate of registration shall be issued for those goods or services recited in the statement of use for which the mark is entitled to registration, and notice of registration shall be published in the Official Gazette of the Patent and Trademark Office. Such examination may include an examination of the factors set forth in subsections (a) through (e) of section 1052 of this title. The notice of registration shall specify the goods or services for which the mark is registered.
(2) The Director shall extend, for one additional 6-month period, the time for filing the statement of use under paragraph (1), upon written request of the applicant before the expiration of the 6-month period provided in paragraph (1). In addition to an extension under the preceding sentence, the Director may, upon a showing of good cause by the applicant, further extend the time for filing the statement of use under paragraph (1) for periods aggregating not more than 24 months, pursuant to written request of the applicant made before the expiration of the last extension granted under this paragraph.

(3) The Director shall notify any applicant who files a statement of use of the acceptance or refusal thereof and, if the statement of use is refused, the reasons for the refusal. An applicant may amend the statement of use.
(4) The failure to timely file a verified statement of use under paragraph (1) or an extension request under paragraph (2) shall result in abandonment of the application, unless it can be shown to the satisfaction of the Director that the delay in responding was unintentional, in which case the time for filing may be extended, but for a period not to exceed the period specified in paragraphs (1) and (2) for filing a statement of use.
(e) Designation of resident for service of process and notices 
If the applicant is not domiciled in the United States the applicant may designate, by a document filed in the United States Patent and Trademark Office, the name and address of a person resident in the United States on whom may be served notices or process in proceedings affecting the mark. Such notices or process may be served upon the person so designated by leaving with that person or mailing to that person a copy thereof at the address specified in the last designation so filed. If the person so designated cannot be found at the address given in the last designation, or if the registrant does not designate by a document filed in the United States Patent and Trademark Office the name and address of a person resident in the United States on whom may be served notices or process in proceedings affecting the mark, such notices or process may be served on the Director.
