Status date

Aug 25, 2026

Deadline

November 25, 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 have a U.S.-licensed attorney represent you because your address is outside the United States, and the search for conflicting trademarks has been temporarily deferred.
