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 has identified that you must appoint a U.S.-licensed attorney to represent your application, and the search for conflicting marks has been deferred until this requirement is met.
