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 requires you to appoint a U.S.-licensed attorney due to an administrative review of your previous representative, and the search for conflicting trademarks has been temporarily deferred. This is a serious issue that will require attention regarding your trademark application.
