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 requires updated examples of how your trademark is used with your goods and needs a more specific description of the software services included in your application.
