Subject to the provisions of section 1058 of this title, each registration may be renewed for periods of 10 years at the end of each successive 10-year period following the date of registration upon payment of the prescribed fee and the filing of a written application, in such form as may be prescribed by the Commissioner. Such application may be made at any time within 1 year before the end of each successive 10-year period for which the registration was issued or renewed, or it may be made within a grace period of 6 months after the end of each successive 10-year period, upon payment of a fee and surcharge prescribed therefor. If any application filed under this section is deficient, the deficiency may be corrected within the time prescribed after notification of the deficiency, upon payment of a surcharge prescribed therefor.

If the registrant is not domiciled in the United States, the registrant shall designate by a written document filed in the Patent and Trademark Office the name and address of some 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, such notice or process may be served upon the Commissioner.
