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 issued a refusal due to potential likelihood of confusion with an existing registered mark and an insufficient specimen showing your services.
