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 domicile is located outside the United States.
