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 a U.S.-licensed attorney to be appointed for your application because your business is located outside the U.S. and your previous attorney's information was removed from the record. Additionally, the examination and search for conflicting marks have been deferred until this representation requirement is satisfied.
