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 has identified that your trademark is considered merely descriptive, that your proof of business use is unacceptable, and that your goods description needs to be made more specific.
