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 refused registration because your mark is considered merely descriptive and confusingly similar to an existing registered mark.
