If papers are transmitted by an attorney at law, or a written power of attorney is filed, the United States Patent and Trademark Office will send correspondence to the attorney at law transmitting the papers, or to the attorney at law designated in the power of attorney. If an application or proceeding is not being prosecuted by an attorney at law, and the applicant, registrant or party to a proceeding before the Office has appointed a domestic representative, the Office will send correspondence to the domestic representative, unless the applicant, registrant or party designates in writing another address to which correspondence is to be sent.
