Statement of Use & Extension Deadline Tracking

What Is a Statement of Use?

A Statement of Use (SOU) is a filing required by the USPTO to prove that your trademark is actually being used in commerce. It applies specifically to applications filed under Section 1(b), the "intent-to-use" basis. When you file an intent-to-use application, you are telling the USPTO that you have a bona fide intention to use the mark but have not started using it yet. The Statement of Use is where you prove you followed through.

The SOU must include a specimen showing the mark as used in commerce in connection with the goods or services identified in the application. For goods, this typically means a photograph of the product or packaging bearing the mark. For services, it usually means advertising or marketing materials showing the mark in connection with the services offered. The specimen must show actual use, not merely an intent to use.

You cannot skip this step. Without a Statement of Use, your application will never mature into a registration. The USPTO issues a Notice of Allowance (NOA) to confirm that your mark has passed examination and any opposition period, but the NOA is not a registration. It is a conditional approval that says: "We will register this mark once you prove you are using it." The SOU is the proof.

For attorneys managing a portfolio of intent-to-use applications, SOU deadlines represent one of the most complex tracking challenges in trademark practice. Each application has its own timeline, its own extension chain, and its own drop-dead date. Unlike office action deadlines that arrive unpredictably, SOU deadlines follow a predictable but multi-step sequence that must be tracked precisely.

Statement of Use Deadlines After Notice of Allowance

Once the USPTO issues a Notice of Allowance, the clock starts. You have 6 months from the NOA issue date to either file a Statement of Use or request your first extension of time.

The initial timeline is straightforward:

• Day 0: Notice of Allowance issued by the USPTO
• Month 6: Deadline to file either a Statement of Use or a Request for Extension of Time to File a Statement of Use

If the mark is already in use at the time the NOA issues, filing the SOU promptly is the best course. But many intent-to-use applications are filed well before the product or service launches. In those cases, extensions are necessary.

Each extension request costs $125 per class of goods or services and must be filed before the current period expires. You cannot request an extension after the deadline has passed. There is no grace period and no petition to revive for a missed SOU or extension deadline. The application is abandoned, full stop.

The extension must include a verified statement that the applicant has a continued bona fide intention to use the mark in commerce. For the first five months of extensions (extensions 1-5), this statement alone is generally sufficient. However, the applicant must be truthful: if there is no genuine intent to use the mark, filing the extension constitutes fraud on the USPTO.

SOU Extension Chains: How Many Can You File?

The USPTO allows up to 5 extensions of time to file a Statement of Use. Each extension grants an additional 6-month period. Combined with the initial 6-month window, this means you have a maximum of 36 months (3 years) from the Notice of Allowance date to file your Statement of Use.

Here is how the full extension chain breaks down:

• Initial period: 6 months from NOA (no fee beyond the original filing)
• Extension 1: Months 6-12 ($125/class)
• Extension 2: Months 12-18 ($125/class)
• Extension 3: Months 18-24 ($125/class)
• Extension 4: Months 24-30 ($125/class)
• Extension 5: Months 30-36 ($125/class). This is the final extension. No further extensions are available.

The total extension cost for a single-class application is $625 (5 extensions at $125 each). For a multi-class application, multiply by the number of classes. An application covering 3 classes would cost $1,875 in extension fees alone over the full 36-month period.

Knowing which extension you are on is critical. Each extension must be filed before the current period expires, and each period is exactly 6 months. If you lose track of where you are in the chain, you risk missing a deadline or, worse, attempting to file a 6th extension that does not exist. DeadlineDocket tracks the extension number for each application and makes it visible in the dashboard, so you always know exactly where you stand.

At the 5th extension, attorneys often face a strategic decision: file the SOU with whatever specimen is available, or let the application go. If the mark still is not in use after 3 years, the applicant must seriously assess whether the intent-to-use basis is still legitimate. Filing a Statement of Use with a specimen that does not show genuine use in commerce can result in a refusal and potential fraud allegations.

What Happens If You Miss a Statement of Use Deadline

If a Statement of Use or extension request is not filed before the current period expires, the application is abandoned. This is not a provisional status. The application is dead.

Unlike office action deadlines, where a petition to revive is available for unintentional delays, there is no petition to revive a missed SOU deadline. The statute is absolute: if the applicant fails to file within the prescribed period, the application is deemed abandoned. The only path forward is to file a new application, which means:

• Loss of priority date: Your new application's filing date becomes the priority date. If a competing mark was filed or used in commerce between your original filing date and the new one, that competitor may now have superior rights.
• Loss of examination work: All the examination, publication, and opposition proceedings that your original application went through are wasted. You start over from scratch.
• Loss of extension fees: Every extension fee you paid on the original application is gone. For multi-class applications with multiple extensions, this can amount to thousands of dollars.
• Re-examination risk: The trademark landscape may have changed. New registrations or applications filed in the interim could create likelihood-of-confusion refusals that did not exist when you originally filed.
• Client relationship damage: Explaining to a client that their application was abandoned because of a missed deadline is one of the most difficult conversations in trademark practice.

The finality of a missed SOU deadline makes it one of the highest-stakes deadlines in trademark prosecution. The 6-month periods feel generous in isolation, but across a portfolio of intent-to-use applications, each at a different stage in its extension chain, the tracking burden adds up quickly. A single missed deadline can undo years of work and thousands of dollars in fees.

How DeadlineDocket Tracks Statement of Use Deadlines

DeadlineDocket detects Notice of Allowance events from the USPTO TSDR record and automatically generates the initial 6-month SOU deadline. From there, the system tracks the entire extension chain.

Here is how the tracking works at each stage:

• NOA detection: When you import a trademark or when a periodic TSDR refresh detects a new Notice of Allowance event, the system generates the initial SOU deadline (6 months from the NOA date).
• Extension chain management: When you mark an SOU deadline as "Filed Extension," the system generates the next 6-month deadline and records which extension number you are on (1 through 5). The dashboard shows the extension number so you can see at a glance how many extensions remain.
• SOU filing tracking: When you mark the deadline as "Filed Statement of Use," the system moves the deadline to a verification state and begins monitoring TSDR for the corresponding filing event.
• Verification: The system checks TSDR for events confirming that the USPTO received your SOU or extension filing. If verification succeeds, the deadline is marked as verified. If it fails after multiple attempts, you receive an alert with enough time to investigate and re-file if necessary.
• Auto-completion: If the TSDR record shows that an SOU or extension was already filed before you started tracking the application, the system detects the relevant events and marks the corresponding deadlines as complete. This prevents false alerts when importing applications that are already mid-chain.

The extension chain is one of the most error-prone areas of manual trademark docketing. Each extension looks the same on a calendar (a 6-month window), but missing one has different consequences depending on where you are in the chain. DeadlineDocket makes the chain state explicit and surfaces the deadline in your weekly digest with the extension number and remaining extensions clearly indicated.

For firms with multiple intent-to-use applications at various stages, the dashboard groups all SOU-related deadlines under the NOA/SOU tab, sorted by urgency. This gives you a single view of every application that needs attention, whether it is approaching its initial SOU deadline or nearing the end of its final extension.
