Deadline

November 25, 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 requires you to be represented by a U.S.-licensed attorney due to your foreign domicile, and the search for conflicting trademarks has been temporarily deferred.
