This article is Part 2 in a series, discussing the USPTO Office of Enrollment and Discipline’s (OED’s) disciplinary opinions impacting trademark attorneys. For other posts in the series, review the Ethics category in this blog.
As promised in the prior post, this article addresses violations of the USPTO’s Signature Rules which have been discussed in myriad OED disciplinary decisions relating to trademark practitioners. For a full collection of all of OED’s decisions dating back to 1996, see https://foiadocuments.uspto.gov/oed/. For a more truncated list that the USPTO recently recommended that trademark attorneys read carefully, see In re Nardone, Proceeding No. D2025-32 at 12-13 (USPTO, May 20, 2026) (also reprinted with active hyperlinks at the end of the prior post).
USPTO Rules Require Personal Signature by Named Signatory
The USPTO’s Signature Rules have been operative for more than 20 years. See In re Stelcore Management Services, LLC et al., Final Order for Sanctions, 2025 WL 1733552 at 3 (USPTO, June 13, 2025) (precedential) (citing Reorganization of Correspondence and Other General Provisions, 68 Fed. Reg. 48289, 48290 (USPTO Final Rule, Aug. 13, 2003) (discussing separation of trademark rules from patent rules, moving the trademark signature requirements from § 1.4 to § 2.193) (PDF copy here)). As of 2003, the Signature Rule required:
(c)(1) Each piece of correspondence that requires a person’s signature, must:
(i) Be an original, that is, have an original signature personally signed in permanent ink by that person; or
(ii) Be a copy, such as a photocopy or facsimile transmission (§ 2.195(c)), of an original. In the event that a copy of the original is filed, the original should be retained as evidence of authenticity. If a question of authenticity arises, the Office may require submission of the original; or
(iii) Where an electronically transmitted trademark filing is permitted or required, the person who signs the filing must either:
(A) Place a symbol comprised of numbers and/or letters between two forward slash marks in the signature block on the electronic submission; or
(B) Sign the verified statement using some other form of electronic signature specified by the Director.
37 C.F.R. § 2.193(c)(1) (Aug. 13, 2003) (emphasis added).
In addition, the Trademark Manual of Examining Procedure (“TMEP”) has long included examples of conduct that would violate these rules. In re Stelcore, Final Order for Sanctions, at 3; see also TMEP § 611.01(b) (Oct. 2012 ed.) (“All documents must be personally signed. … Another person (e.g., paralegal, legal assistant, secretary) may not sign the name of an attorney or other authorized signatory.”) (quoting In re Dermahose Inc., Ser. No. 76585901, 82 USPQ2d 1793, 2007 TTAB LEXIS 25, slip op. (TTAB Feb. 13, 2007); In re Cowan, Reg. No. 1225389, 18 USPQ2d 1407, 1990 Commr. Pat. LEXIS 24 (Comm’r Pats. 1990)).
This “personally signed” requirement applies regardless of whether the signature at issue is handwritten or typed. 37 CFR §§ 2.193 (a) & (c); TMEP § 611.01(c) (“… Just as signing the name of another person on paper does not serve as the signature of the person whose name is written, typing the electronic signature of another person is not a valid signature by that person.”). Instead, only the person whose name is identified in the signature block may enter their own signature – in any form. Id.
This signatory authority cannot be delegated to anyone else. In re Stelcore, Final Order for Sanctions, at 3 (“A person may not delegate the authority to sign trademark-related submissions, and no party may sign the name of another.”); see also TMEP § 611.01(b). In other words, you cannot authorize anyone else to sign your name for you. Neither may an attorney nor their staff – or any other third-party – sign a client’s name in the client’s signature block – even if that client provided you with express written authorization to do so. Instead, the named signatory on any filing must personally apply their own signature – in whatever form such signature would be captured. 37 C.F.R. §2.193(a)(1), (c)(1).
The USPTO recently confirmed in a precedential opinion that this requirement is substantive, not merely technical. In re Stelcore, Final Order for Sanctions, at 3. As a result, failure to comply with the requirement for all signatures to be “personally signed” or “personally entered” can invalidate a trademark filing and “may jeopardize the validity of an application or registration.” 37 C.F.R. § 2.193(f). Applications improperly signed have been deemed void ab initio, and such signature violations cannot be corrected. In re Stelcore, Final Order for Sanctions, at 10 (“Although Respondents request to correct the signatures, correction is not available. The defects in these signatures are more than mere technical errors and cannot be corrected or perfected under 35 U.S.C. § 26.”); id. at 12 (“Respondents’ conduct [of forging signatures] has infected these trademark matters, resulting in false submissions being made to the USPTO that in most if not all cases would render the applications void ab initio.”).
Common Fact Patterns
Many of the OED opinions addressing signature violations reveal the following fact patterns:
- An attorney signed a client’s name on a declaration before filing;
- An attorney allowed (or instructed) a paralegal or other support staff in their practice to sign the attorney’s (or client’s) name on documents to be filed with the USPTO;
- A paralegal or other support staff signed the attorney’s name (or the client’s name) on documents to be filed with the USPTO, without the attorney’s (or client’s) knowledge or consent; or
- A foreign filing firm acting as an intermediary between the attorney and the individual clients applied the attorney’s signature (or the individual client’s signature) on their behalf (with or without their knowledge) to documents for filing with the USPTO.
In more recent OED decisions, the USPTO listed disciplinary opinions that it recommended trademark attorneys read and become familiar with. The most recent list appeared at the end of the OED’s decision in In re Nardone, Proceeding No. D2025-32, Final Order (USPTO, May 20, 2026) – and was reprinted with active links at the end of the prior post in this series.
