Status date

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 us to appoint a U.S.-licensed attorney for your application because your previous representative is no longer on record and your address is outside the United States. Additionally, the search for conflicting trademarks has been temporarily deferred.
