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 requires administrative review due to your previous representative and that you need to have a U.S.-licensed attorney represent you.
