37 CFR 104.12 - Acceptance of service of process.
(a) Any summons and complaint to be served in person or by registered or certified mail or as otherwise authorized by law on the Office, on the Director, or on an employee in his or her official capacity, shall be served as indicated in § 104.2.
(b) Any employee of the Office served with a summons and complaint shall immediately notify, and shall deliver the summons and complaint to, the Office of the General Counsel.
(c) Any employee receiving a summons and complaint shall note on the summons and complaint the date, hour, and place of service and whether service was by hand or by mail.
(d) When a legal proceeding is brought to hold an employee personally liable in connection with an action taken in the conduct of official business, rather than liable in an official capacity, the employee by law is to be served personally with process. See Fed. R. Civ. P. 4(e). An employee sued personally for an action taken in the conduct of official business shall immediately notify and deliver a copy of the summons and complaint to the General Counsel.
(f) The Office will only accept service of process for an employee in the employee's official capacity.
