Sec. 2.193. Trademark correspondence and signature requirements.
(2) An electronic signature that meets the requirements of paragraph (c) of this section, personally entered by the person named as the signatory. The Office will accept an electronic signature that meets the requirements of paragraph (c) of this section on correspondence filed on paper, by facsimile transmission (§2.195(c)), or through TEAS or ESTTA.
(b) Copy of original signature. If a copy, such as a photocopy or facsimile copy of an original signature is filed, the filer should retain the original as evidence of authenticity. If a question of authenticity arises, the Office may require submission of the original.
(2) Sign the verified statement using some other form of electronic signature specified by the Director.
(d) Signatory must be identified. The name of the person who signs a document in connection with a trademark application, registration, or proceeding before the Trademark Trial and Appeal Board must be set forth in printed or typed form immediately below or adjacent to the signature, or identified elsewhere in the filing ( e.g., in a cover letter or other document that accompanies the filing).
(iii) An attorney as defined in §11.1 of this chapter who has an actual written or verbal power of attorney or an implied power of attorney from the owner.
(ii) If the owner is not represented by a practitioner qualified to practice under §11.14 of this chapter, the individual owner or someone with legal authority to bind the owner ( e.g., a corporate officer or general partner of a partnership) must sign. In the case of joint owners who are not represented by a qualified practitioner, all must sign.
(3) Powers of attorney and revocations of powers of attorney. Powers of attorney and revocations of powers of attorney must be signed by the individual applicant, registrant or party to a proceeding pending before the Office, or by someone with legal authority to bind the applicant, registrant, or party ( e.g., a corporate officer or general partner of a partnership). In the case of joint applicants, registrants, or parties, all must sign. Once the applicant, registrant or party has designated a qualified practitioner(s), the named practitioner may sign an associate power of attorney appointing another qualified practitioner(s) as an additional person(s) authorized to prosecute the application or registration. If the applicant, registrant, or party revokes the original power of attorney, the revocation discharges any associate power signed by the practitioner whose power has been revoked. If the practitioner who signed an associate power withdraws, the withdrawal discharges any associate power signed by the withdrawing practitioner upon acceptance of the request for withdrawal by the Office.
(4) Petitions to revive under §2.66. A petition to revive under §2.66 must be signed by someone with firsthand knowledge of the facts regarding unintentional delay.
(ii) If the petitioner is not represented by a practitioner authorized to practice before the Office under §11.14 of this chapter, the individual petitioner or someone with legal authority to bind the petitioner ( e.g., a corporate officer or general partner of a partnership) must sign. In the case of joint petitioners, all must sign.
(6) Requests for correction, amendment or surrender of registrations. A request for correction, amendment or surrender of a registration must be signed by the owner of the registration, someone with legal authority to bind the owner ( e.g., a corporate officer or general partner of a partnership), or a practitioner qualified to practice before the Office under §11.14 of this chapter. In the case of joint owners who are not represented by a qualified practitioner, all must sign.
(7) Renewal applications. A renewal application must be signed by the registrant or the registrant's representative.
(8) Designations and revocations of domestic representative. A designation or revocation of a domestic representative must be signed by the applicant or registrant, someone with legal authority to bind the applicant or registrant ( e.g., a corporate officer or general partner of a partnership), or a practitioner qualified to practice under §11.14 of this chapter. In the case of joint applicants or registrants, all must sign.
(ii) If the applicant or registrant is not represented by a practitioner qualified to practice before the Office under §11.14, the individual applicant or registrant or someone with legal authority to bind the applicant or registrant ( e.g., a corporate officer or general partner of a partnership) must sign. In the case of joint applicants or joint registrants, all must sign.
(10) Cover letters. A person transmitting paper documents to the Office may sign a cover letter or transmittal letter. The Office neither requires cover letters nor questions the authority of a person who signs a communication that merely transmits paper documents.
(f) Signature as certification. The presentation to the Office (whether by signing, filing, submitting, or later advocating) of any document by any person, whether a practitioner or non-practitioner, constitutes a certification under §11.18(b) of this chapter. Violations of §11.18(b) of this chapter may jeopardize the validity of the application or registration, and may result in the imposition of sanctions under §11.18(c) of this chapter. Any practitioner violating §11.18(b) of this chapter may also be subject to disciplinary action. See §§10.23(c)(15) and 11.18(d) of this chapter.
(g) Separate copies for separate files.
(1) Since each file must be complete in itself, a separate copy of every document to be filed in connection with a trademark application, registration, or inter partes proceeding must be furnished for each file to which the document pertains, even though the contents of the documents filed in multiple files may be identical.
(2) Parties should not file duplicate copies of correspondence in a single application, registration, or proceeding file, unless the Office requires the filing of duplicate copies. The Office may dispose of duplicate copies of correspondence.
(h) Separate documents for separate branches of the Office. Since different branches or sections of the Office may consider different matters, each distinct subject, inquiry or order must be contained in a separate document to avoid confusion and delay in answering correspondence.
(i) Certified documents required by statute. When a statute requires that a document be certified, a copy or facsimile transmission of the certification is not acceptable.
