Status date

Deadline

September 29, 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 found no conflicting marks, but requires you to be represented by a U.S.-licensed attorney because your address is outside the United States.
