Deadline

November 13, 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 USPTO requires you to be represented by a U.S.-licensed attorney due to an administrative review of your previous representative, and the substantive examination of your trademark has been temporarily deferred.
