Status date

Deadline

January 20, 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 USPTO examiner requires you to appoint a U.S.-licensed attorney because your previous attorney was removed from the record, and has deferred the search for conflicting trademarks until this requirement is addressed.
