A trademark statement of use is a document that is filed with the United States Patent and Trademark Office (USPTO) to demonstrate that a trademark that was the subject of an intent-to-use application is now in use in commerce.

An intent-to-use application is a type of trademark application that is filed when the applicant has a good faith intention to use the trademark in commerce, but the trademark has not yet been used. In order to obtain a trademark registration, the applicant must demonstrate that the trademark is being used in commerce. This can be done by filing a statement of use, along with a specimen showing how the trademark is being used in commerce.

A trademark statement of use must be filed within a certain time period after the USPTO approves the intent-to-use application. The specific time period will depend on the circumstances of the application, and may be extended in certain circumstances.

If the USPTO determines that the statement of use and specimen provided by the applicant meet the necessary requirements, the trademark registration will be issued. If the USPTO determines that the statement of use and specimen do not meet the requirements, the applicant may be required to file a revised statement of use or may need to abandon the application.

It is a good idea to consult with a trademark attorney or other professional to assist with the process of filing a trademark statement of use and to ensure that your application meets the necessary requirements.
