Deadline

January 22, 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 update your application with your actual permanent domicile address instead of a registered agent address, and notes that you must appoint a U.S.-licensed attorney if your domicile is outside the United States.
