The party not domiciled in the United States may designate by submission filed in the Office the name and address of a person residing in the United States on whom may be served notices or process in the proceeding. If the party has appointed a domestic representative, official communications of the Office will be addressed to the domestic representative unless the proceeding is being prosecuted by an attorney at law or other qualified person duly authorized under § 11.14(c) of this chapter. If the party has not appointed a domestic representative and the proceeding is not being prosecuted by an attorney at law or other qualified person, the Office will send correspondence directly to the party, unless the party designates in writing another address to which correspondence is to be sent. The mere designation of a domestic representative does not authorize the person designated to prosecute the proceeding unless qualified under § 11.14(a) of this chapter, or qualified under § 11.14(b) of this chapter and authorized under § 2.17(f) .(e) Every submission filed in an inter partes proceeding, and every request for an extension of time to file an opposition, must be signed by the party filing it, or by the party's attorney or other authorized representative, but an unsigned submission will not be refused consideration if a signed copy is submitted to the Office within the time limit set in the notification of this defect by the Office. 81 FR 69975 , Oct. 7, 2016 Part 3 pertaining to both patents and trademarks is placed in the grouping pertaining to patents regulations.
