Status date

Deadline

December 8, 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 appoint a U.S.-licensed attorney because your previous representative was removed from the record, and has deferred the search for conflicting marks until this requirement is addressed.
