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 trademark office requires your application to be represented by a U.S.-licensed attorney, and the search for conflicting trademarks has been temporarily deferred until this requirement is met.
