Status date

Deadline

September 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 because your address is outside the United States, and the search for conflicting trademarks has been temporarily deferred.
