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 requires you to appoint a U.S.-licensed attorney because your previous representative is under administrative review, and the search for conflicting marks has been deferred. This is a serious issue for your application.
