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 additional information regarding your Class 41 and 42 services and maintains the specimen refusals for those classes. You will need to submit acceptable substitute specimens and respond directly to the examiner's questions about your services.
