602.03(c) Documents Filed by Foreign Attorneys and Agents
A foreign attorney or agent who is not authorized to practice before the USPTO under 37 C.F.R. §11.14 may receive correspondence from the USPTO and transmit it to the applicant or registrant. However, a foreign attorney or agent cannot prepare an application, response, post-registration maintenance document, or other document to be filed in the USPTO, sign responses to Office actions, or authorize issuance of examiner’s amendments and priority actions. Preparing a document, authorizing an amendment to an application, and submitting legal arguments in response to a requirement or refusal all constitute examples of representation of a party in a trademark matter. See 37 C.F.R. §11.5(b)(2); TMEP §608.01.
If a foreign attorney or agent who does not meet the requirements of 37 C.F.R. §11.14(c) is designated or acts as a representative of a party in a trademark matter, the USPTO will treat any document submitted by the attorney or agent as a document filed by an unauthorized party and follow the procedures in TMEP §§611.05–611.05(c).
