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 service description is indefinite and spans multiple international classes, and that your attorney bar credentials must be formally provided to the USPTO.
