Deadline

November 28, 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 you need to appoint a U.S.-licensed attorney because your address is outside the United States, and that the search for conflicting marks has been deferred.
