SOU — a sworn statement attesting to use of the mark in commerce. The Statement of Use is signed by the applicant or a person authorized to sign on behalf of the applicant.
An SOU must be submitted with:
- The required filing fee for each class of goods/services; and
- A specimen showing use of the mark in commerce for each class of goods/services.
A Statement of Use must be filed within 6 months from the date the USPTO issues a notice of allowance. Failure to submit the statement of use in a timely manner results in abandonment of the application. The Amendment to Allege Use and the Statement of Use include the same information, and differ only as to the time when it is filed.
