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 found no conflicting marks, but requires you to clarify and properly classify your services across multiple classes and submit the required fees for the additional class.
