Filing Format and Who May Sign

Two USPTO rules: the non-DOCX surcharge from 17 January 2024, and signing software from 22 March 2024. Read from the primary document; quotations verified against its own text.

What it says

The USPTO delayed its non-DOCX filing surcharge to January 17, 2024, and separately, effective March 22, 2024, began permitting patent correspondence to be signed through third-party document-signing software such as DocuSign or Acrobat Sign, provided the software preserves the signature data and the named signer personally makes their own signature.

Two rules govern how a filing is formatted and who may sign it. The first delayed the non-DOCX filing surcharge until January 17, 2024, so a utility application whose specification, claims and abstract are not filed in DOCX now carries an extra fee. The second, effective March 22, 2024, permits signing through third-party software such as DocuSign or Acrobat Sign, which the USPTO had not previously allowed. That flexibility comes with a limit worth reading twice: the software may carry the signature, but the named signer must personally make it. Delegating the act to staff is not what the rule permits, whatever the software makes technically possible.

The two rules share no authority, no date and no subject beyond filing integrity. They sit on one page because a practitioner meets them as one problem. Anyone citing either should cite the rule, not this page.

The DOCX Rule Moves a Date

It does one thing. The surcharge itself was created by an earlier rule in 2020, "implementing a non-DOCX filing surcharge fee" at 37 CFR 1.16(u); this rule delays its bite: "the USPTO is delaying the effective date of this fee until January 17, 2024."

The operational consequence is that the surcharge's authority and its date live in different documents. A reader who finds only the 2023 rule learns when the fee starts and not what it is; a reader who finds only the 2020 rule learns the reverse. The amount lives in neither; it is in the fee schedule. And the surcharge is a fee decision, not a validity one. Nothing in it affects a filing's legal effect, only its cost, which distinguishes it from the foreign-representation rule in this corpus, where a formatting defect can destroy a benefit claim.

The Signature Rule Opens a Mechanism, Not a Role

The three conditions in the electronic-signature rule, 89 FR 20321, and how each is tested. As of 15 August 2026.
Condition What the rule says How it is tested
The softwareMust "preserve signature data for later inspection in the form of a digital certificate, token, or audit trail"Presumed satisfied
The presumption"USPTO personnel may presume that the document-signing software preserves signature data" unless the Office notifies them otherwiseCuts in the filer's favour; nobody asks which software
The signer"The signer must personally make their own signature, regardless of what type of signature is used"Not relaxed at all

The rule revised the signature requirements to provide for "the broader permissibility of electronic signatures using third-party document-signing software," naming DocuSign and Acrobat Sign as examples, in order to "more closely align signature requirements with the rules of practice in trademark cases."

The conditions divide cleanly. The software requirement is presumed satisfied. The human requirement is not relaxed at all. A signature workflow that routes a document through compliant software but lets someone other than the named signer apply the signature satisfies the presumed half and violates the unrelaxed half. Only the condition is enforceable against the filer: nobody will ask which software was used, and the question that could be asked is who pressed the button.

"The signer must personally make their own signature" is not defined against any workflow. The rule states the requirement and does not say what supervision, delegation or automation would breach it. Where the line sits is an inference from the sentence, not a holding, and a workflow that makes it impossible for staff to apply a practitioner's or an inventor's signature on their behalf is the one that does not depend on the answer.

What This Does Not Decide

Naming a product is reporting, not recommending. The rule names DocuSign and Acrobat Sign as examples of a category. Repeating that is description. Treating it as an endorsement of either product is not, and this page does not endorse one.
  • It does not say whether a particular signature workflow complies.
  • It does not say whether a specific filing owes the surcharge.
  • It concerns filing format and signature mechanics, and says nothing about patentability.

Educational, not legal advice. This page reports what an authority says. Applying it to a matter is work for a registered practitioner with the file in front of them.
