Deadline

January 20, 2027

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 appoint a U.S.-licensed attorney because your domicile is outside the United States and your previous attorney was removed from the record. Additionally, the search for conflicting trademarks has been deferred until this requirement is met.
