Status date

Deadline

November 30, 2026

Status 641 means the USPTO mailed a non-final Office Action identifying issues with your application. You typically have three months to respond with arguments, amendments, or evidence. Missing the deadline can abandon the application.

The examiner has identified that your application requires a U.S.-licensed attorney because your address is outside the United States, and the search for conflicting trademarks has been temporarily deferred during an administrative review.
