If you are a trademark owner, receiving notice from the United States Patent and Trademark Office that your registration is under review can be stressful. A post-registration audit ensures that trademarks are actively used for the goods or services listed in the registration.
The USPTO randomly selects certain filings, but sometimes audits occur when there is a concern about compliance. Responding properly is critical to maintaining your trademark rights for businesses and the public.
This guide explains the audit process, how to respond to an office action, what evidence to submit, and the possible outcomes.

What Is a Trademark Registration Audit?
A trademark registration audit is a formal review conducted by the USPTO to verify that the trademark is still used in commerce for the goods or services listed. The goal is to maintain an accurate trademark register and provide notice of trademark rights to businesses relying on the registry.
During the audit, the USPTO may request a response to an office action requiring the trademark owner to submit proof of use. This proof shows that the trademark is actively used in commerce for the audited items. If the mark is no longer used for certain services in your registration, the USPTO may require the deletion of those goods or services.
Why the USPTO Conducts Audits?
Audits exist to protect both trademark owners and the public. Over time, registrations may become inaccurate due to:
- Services are longer in use
- Changes in the business model
- Overly broad goods or services listed
- Past filings without adequate documentation
Maintaining accuracy helps prevent disputes and ensures that trademark rights are enforced only for active products and services identified in the registration.
| Did You Know? A US Department of Commerce study found that nearly fifty percent of registrations reviewed contained at least one item no longer in use. |
How Trademark Owners Are Notified?
Trademark owners receive an audit office action, also referred to as a notice of trademark rights verification.
The office action details:
- Which goods or services are under review
- Deadline to respond, typically six months
- Instructions on what documentation is acceptable
Failing to respond to the audit or provide acceptable proof of use may lead the USPTO to delete goods or services or, in extreme cases, the entire registration will be canceled.
What You Must Submit During an Audit
The USPTO requires evidence that shows the trademark is used for each item listed in the trademark registration.
Examples of acceptable submissions include:
- Photographs of the mark on products, packaging, or labels
- Screenshots of online sales or listings showing the trademark is actively used
- Point-of-sale material or marketing content
- Declarations from the business confirming commercial use
Tips for submitting proof:
- Include multiple types of evidence for each good and service
- If an item is no longer in use, proactively delete goods or services
- Keep records organized for easier response to the office action

Common Outcomes of a Trademark Audit
The audit process can result in several scenarios:
- Audit accepted
The submitted documentation satisfies the USPTO, and no changes are required.
- Partial deletion
Items no longer used are deleted from the registration.
- Second office action
If the response is unclear or insufficient, the USPTO may request more evidence.
- The entire registration will be canceled
Rare, but possible if no acceptable proof of use is provided.
- Additional monitoring
Some registrations may undergo follow-up checks or future audits.
Proper preparation can reduce the risk of deletion or cancellation.
How to Avoid Problems During a Trademark Audit
Proactive steps to prevent audit issues:
- Regularly review your services in your registration and remove items no longer in use
- Maintain detailed records of commercial use, including sales receipts, labels, or photographs of the mark
- Conduct internal checks years after registration as part of registration maintenance
- Work with a trademark attorney to ensure compliance and organize your response
| Key point: Businesses that maintain organized records and accurate registrations experience fewer challenges during audit office actions. |
