Status date

Deadline

January 25, 2027

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 examiner requires you to appoint a U.S.-licensed attorney because your address is outside the United States, and has deferred the search for conflicting trademarks until current issues are resolved.
