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 found no conflicting marks with your trademark, but the examiner requires a substitute specimen demonstrating proper use of your mark with your software services.
