The USPTO’s audit procedure sets up a ‘use it or lose it’ proposition. The owner of a registered trademark has to file a declaration of use between the 5th and 6th year after registration and then on every 10th anniversary of registration. The USPTO will conduct random audits of about 10% of the filed declarations of use. The USPTO’s audit system will maintain the integrity of the trademark registration system by insuring that a trademark is actually being used for the registered goods and services. If the trademark owner cannot provide sufficient specimens of use, the goods or services will be deleted from the trademark registration.

**WHY YOU SHOULD KNOW THIS. **Over time, a trademark owner may drop or develop new goods or services. When it comes time to file maintenance and renewal documents, the specimens of use will change too. A trademark owner can avoid audit problems by conducting a detailed review of their registrations before filing maintenance and renewal documents. If product lines or services are no longer being offered, the maintenance and renewal documents should reflect the changes.
