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 your application is undergoing an administrative review and that you need to appoint a U.S.-licensed attorney. Additionally, the search for conflicting marks has been deferred until these issues are resolved.
