(a) Except as otherwise provided in this subpart, any summons or complaint to be served in person or by registered or certified mail or as otherwise authorized by law on the Department, a component or the Secretary or a Department employee in their official capacity, shall be served on the General Counsel of the United States Department of Commerce, Washington, DC 20230.

(b) Any summons or complaint to be served in person or by registered or certified mail or as otherwise authorized by law on the Patent and Trademark Office or the Commissioner of Patents and Trademarks or an employee of the Patent and Trademark Office in his or her official capacity, shall be served on the Solicitor for the Patent and Trademark Office or a Department employee designated by the Solicitor.

(c) Except as otherwise provided in this subpart, any component or Department employee served with a summons or complaint shall immediately notify and deliver the summons or complaint to the office of the General Counsel. Any employee of the Patent and Trademark Office served with a summons or complaint shall immediately notify and deliver the summons or complaint to the office of the Solicitor.

(d) Any Department employee receiving a summons or complaint shall note on the summons or complaint the date, hour, and place of service and whether service was by personal delivery or by mail.

(e) When a legal proceeding is brought to hold a Department employee personally liable in connection with an action taken in the conduct of official business, rather than liable in an official capacity, the Department employee by law is to be served personally with process. Service of process in this case is inadequate when made upon the General Counsel or the Solicitor or their designees. Except as otherwise provided in this subpart, a Department employee sued personally for an action taken in the conduct of official business shall immediately notify and deliver a copy of the summons or complaint to the office of the General Counsel. Any employee of the Patent and Trademark Office sued personally for an action taken in the conduct of official business shall immediately notify and deliver a copy of the summons or complaint to the Office of the Solicitor.

(f) A Department employee sued personally in connection with official business may be represented by the Department of Justice at its discretion. See 28 CFR 50.15 and 50.16 (1987).

(g) The General Counsel or Solicitor or Department employee designated by either, when accepting service of process for a Department employee in an official capacity, shall endorse on the Marshal's or server's return of service form or receipt for registered or certified mail the following statement: “Service accepted in official capacity only.” The statement may be placed on the form or receipt with a rubber stamp.

(h) Upon acceptance of service or receiving notification of service, as provided in this section, the General Counsel and Solicitor shall take appropriate steps to protect the rights of the Department, component, the Secretary or Department employee involved.
