Deadline

November 24, 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 appoint a U.S.-licensed attorney because your business is located abroad and your previous attorney's details were removed, and the search for conflicting trademarks has been deferred until this is addressed.
