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 an acceptable domicile street address and determined that your claim of acquired distinctiveness based on five years of use is insufficient.
