US Statement of Use Extensions: 2026 USPTO Rules

US Statement of Use Extensions: 2026 USPTO Rules

After the USPTO issues a Notice of Allowance, you get six months to file a complete Statement of Use or a six‑month extension. You can request up to five extensions in total, which sets a hard 36‑month outer limit from the NOA. Later extensions need good cause. Each request costs $125 per class via TEAS. The USPTO also endorses an insurance extension to preserve time. (Sources: USPTO ITU forms page; USPTO ITU overview; USPTO guidance on insurance extensions; TMEP § 1108.01.)

You likely know the cadence. What most applicants miss are the failure modes. Below is the practical playbook we use for ITU clients, with dates, fees, what to say in good‑cause statements, and when we pull the insurance trigger.

What are the SOU deadlines and the extension cap in 2026?

You have six months from the NOA to either file the SOU or request an extension. You may then file additional six‑month extensions, up to a total of five. That creates a non‑extendable outer limit of 36 months from the NOA to submit a complete SOU. If you do not file a complete SOU or a valid extension on time, the application goes abandoned, and you cannot file an SOU after the 36‑month cap. (USPTO ITU forms and overview; TMEP § 1108.01.)

• NOA date, start the first 6‑month window.
• End of each window, file either the SOU or another 6‑month extension.
• Absolute stop at 36 months from NOA for a complete SOU.

How many extensions can you request, and what qualifies as good cause?

Up to five six‑month extensions are allowed. The first request is straightforward. Later requests must include a good‑cause statement, which explains concrete, ongoing steps to get the mark into use in commerce. Vague intent language will not do. (USPTO insurance extension guidance; TMEP § 1108.01.)

Examples that typically support good cause:

• Signed or pending manufacturing agreements, tooling, or packaging orders.
• Beta testing or pilot sales with a defined rollout plan and dates.
• Active distributor or retailer negotiations, including draft POs.
• Regulatory steps that affect launch timing, such as label approvals or safety testing.
• Website build, app store listing preparations, or logistics contracts tied to a go‑live date.

Risky or weak statements:

• “We still intend to use the mark.” Too bare.
• “We are considering changes.” Non‑committal.
• “We were busy.” No ongoing commercial steps.

Try this structure:

• What you are launching, with the exact goods or services as filed.
• The specific tasks completed since the last period, with dates.
• The next milestones in the next six months, also with dates.

As counsel, we attach brief exhibits when helpful, for example a redacted purchase order or a screen capture of pre‑launch product pages. You do not need to over‑share, but substance helps.

What must a complete SOU include?

A complete SOU includes three pillars, per the USPTO overview page:

• A verified statement that the mark is in use in commerce for the listed goods or services in each class.
• A proper specimen of use for each class.
• The required USPTO fees.

Specimens are the most common tripwire. If you are not sure what the USPTO will accept for your goods or services, read our guide on Trademark Specimens: What the USPTO Accepts and Rejects.

What is an insurance extension, and when should you use it?

An insurance extension is a timing tactic. You file an extension request on the last day of your current extension period, then file the SOU the next day. If the SOU is perfect, the extension simply expires without effect. If the SOU is refused or deficient, you preserved another six months to cure. The USPTO describes and endorses this approach. (See USPTO guidance on maximizing use of an insurance extension.)

When we recommend it:

• You are close to launch and confident in use, but the specimen or dates might draw questions.
• You are filing for multiple classes and use is solid in some but not all.
• Your specimen is new to the category, for example software onboarding flows for SaaS services.

How we execute it for clients:

1) Calendar the last day of the extension period. File the extension that day.

2) File the SOU the very next day for the classes already in use.

3) If an examining attorney refuses the specimen or asks for more, respond within the new 6‑month buffer.

This tactic has saved more than one launch. For example, a footwear client filed a Class 25 SOU with an e‑commerce product page as a specimen. The examiner questioned the image‑only display. Because we had banked an insurance extension, we switched to a hangtag photograph and a dated invoice without losing the filing.

How much do SOU extensions cost, and how should you plan by class?

Each SOU extension request costs $125 per class, filed through TEAS. That fee repeats with each request. If you have three classes and you extend three times, you will pay 3 classes × 3 requests × $125 per class. Build that into your budget. (USPTO ITU forms page.)

Two practical tips from our files:

• If you are already in use in some classes but not others, consider filing the SOU for the used classes now and extending only the rest. You pay only for the classes you extend.
• Draft goods and services precisely at filing. Overbroad identifications are harder to support with in‑commerce specimens a year later.

What happens if you miss a deadline or hit the 36‑month cap?

If you fail to file either a complete SOU or a valid extension on time, the application abandons. Once the 36‑month outer limit from the NOA passes, you cannot file an SOU for that application. At that point, your practical option is to refile. You may lose your original priority date and may face new citations that were not there before. (USPTO ITU overview; TMEP § 1108.01.)

We have seen founders cut it too close on a final window, then learn the specimen was not acceptable. Without an insurance extension in place, there was no time left to cure. They had to start over.

How we help

We are an attorney‑led team. We calendar every SOU date, prepare good‑cause narratives with concrete evidence, and file through TEAS. If an examining attorney raises issues, we handle the response. If you want us to take this off your plate, start here: /services/sou-filing.
