Filing a Statement of Use: Avoid These Common Mistakes That Delay Your Trademark

October 2, 2025/Adams Law Office/

When filing a Statement of Use with the USPTO under an “Intent to Use” (ITU) basis, it’s one of the most critical steps before your trademark can be registered. 

While the concept seems straightforward, proving that your trademark is actively being used in commerce, many applicants make errors that can cause costly delays, extensions, or even abandonment of the application.

Common Mistakes to Avoid Trademark Delay While Filing a Statement of Use

In this guide, we will break down the most common mistakes people make when filing an SOU and how you can avoid them.

1. Submitting Incorrect Specimens of Use

One of the top reasons SOUs are delayed is due to inadequate or incorrect specimens. A specimen must clearly show the trademark being used in commerce, not just on marketing materials.

  • For goods, acceptable specimens often include product packaging, labels, or photos of the mark directly on the goods.
  • For services, a proper specimen could be a website screenshot offering the service, a brochure, or an advertisement that clearly associates the trademark with the service being sold.

Submitting a digital mock-up, printer’s proof, or placeholder image will almost always lead to refusal.

2. Filing the SOU Too Early or Too Late

Timing is everything. Filing too early, before your mark is genuinely used in commerce, can result in a refusal. Filing too late risks missing USPTO deadlines, which could lead to application abandonment.

The USPTO typically gives you six months from the Notice of Allowance (NOA) to file an SOU, with possible extensions of up to three years. Miscalculating these deadlines is a costly mistake.

3. Misidentifying Goods and Services in the SOU

Applicants often mistakenly expand or change the scope of goods/services when filing the SOU. The SOU must align with what was listed in the application. If the description does not match, it can trigger an Office Action or delay approval.

4. Problems with Declarations and Signatures

Every SOU requires a sworn declaration and signature affirming that the mark is being used in commerce. Common issues include:

  • Having the wrong party sign the form.
  • Using an electronic signature incorrectly.
  • Submitting a declaration with false or incomplete information.

Errors in this step may invalidate the filing or cause processing delays.

5. Overlooking Attorney Review

Many DIY applicants underestimate the complexity of the SOU process. Small errors like a weak specimen, a wrong filing date, or an incomplete declaration can snowball into a full refusal. A trademark attorney can review your SOU, confirm that your specimens meet USPTO standards, and ensure everything is filed correctly.

6. Correcting Mistakes After Filing an SOU

If you realize after submission that you’ve made a mistake, you may be able to amend certain aspects of the SOU. However, not all issues are fixable. For instance, if you filed with a non-acceptable specimen, you may need to submit a new specimen or request additional time.

Delays from correcting these mistakes can push your registration timeline back by months.

7. Missing SOU Deadlines and Facing Abandonment

Missing the SOU deadline without filing an extension request is one of the fastest ways to lose your trademark application entirely. Once abandoned, you will either have to restart the application process or fight to revive it, both of which cost extra time and money.

8. Extra Costs of Correcting Mistakes

Each SOU filing has an associated government fee, and so do extensions. If you make errors, correcting them can add up quickly both in filing fees and attorney costs. Avoiding mistakes at the start is far more affordable than fixing them later.
