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 must appoint a U.S.-licensed attorney to represent you, and the search for conflicting trademarks has been temporarily deferred until this requirement is met.
