What Is a Statement of Use for a Trademark Application and When Is It Due?

What a Statement of Use is

A Statement of Use is the USPTO filing where an intent-to-use applicant proves they have started using the mark in commerce for the goods or services in the application. In plain English, it is the "we are live now" paperwork. The USPTO needs it before the application can proceed to registration. Markavo describes it the same way: a declaration that the mark is actively used on the goods and services listed, supported by real evidence of use in commerce (Markavo).

When it is required

A Statement of Use is required only for intent-to-use applications. If the application was already filed on a use-in-commerce basis, this extra step is not the same thing, because use has already been claimed from the start.

And yes, this matters. Without the Statement of Use, an intent-to-use application does not make it to registration. The application may sit there looking important and official, but it is still waiting on proof that the mark is actually in use.

When it is due

The due date ties directly to the Notice of Allowance. After the USPTO issues that notice, the applicant must file the Statement of Use within the USPTO deadline that follows, or request an extension if eligible. The USPTO’s rules and filing guidance lay out this timing in the intent-to-use process, including the Notice of Allowance step and the post-notice filing deadlines (USPTO intent-to-use filing guidance).

So the practical rule is straightforward, even if your docketing calendar makes it annoying: once the Notice of Allowance arrives, the clock starts.

What must be shown in the filing

Before filing, the applicant should confirm three practical things:

• Proof of actual use. There needs to be real evidence that the mark is being used in commerce.
• The mark as used. The version shown in the evidence should match the mark in the application.
• The evidence matches the goods or services. The specimen or proof of use should line up with what the application covers, not some nearby category the business also happens to sell.

This is the part where applicants often learn that "close enough" is not a filing strategy.

Worked example: intent-to-use application timeline

Imagine a company files an intent-to-use trademark application for a brand of stationery. At filing, the product line is still being finalized, so there is no actual use yet. The application is examined, and later the USPTO issues a Notice of Allowance.

Now the company starts selling the stationery with the mark on the packaging. Once that launch happens, the applicant files the Statement of Use with evidence showing the mark on the goods as sold.

Why does the filing date matter? Because the application cannot just coast forever on good intentions. The Statement of Use has to land within the USPTO’s allowed window after the Notice of Allowance, or the application stalls, and nobody likes a stalled application unless they are a parking brake.

Why this matters if you monitor new trademark filings

If you monitor a competitor’s trademark filing, you are usually seeing application status, not final rights. A pending intent-to-use application can still be sitting in the queue before the Statement of Use is filed, which means registration is not yet available.

That is why monitoring is useful, but incomplete. It tells you where the application is in the process, not whether the applicant has cleared the final use hurdle. If you want the broader monitoring picture, our guide on how to monitor new trademark filings at the USPTO explains how status tracking fits into a larger watch process, and what tracking USPTO trademark filings tells you about competitors shows why application timing can still matter even before registration.

FAQ

What happens if the Statement of Use is late?

If it is not filed by the USPTO deadline, the application will not move forward to registration unless the applicant has properly extended the time or otherwise preserved the application under the USPTO’s rules.

Can an applicant extend the deadline?

Yes, in the intent-to-use process the applicant can request extensions if eligible, and those extensions are part of the USPTO timeline after the Notice of Allowance.

Is a Statement of Use the same as proof of registration?

No. It is proof of use for an intent-to-use application, not proof that the trademark is already registered. Registration comes later, if the USPTO accepts the filing and the application clears the remaining steps.
