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 a prior-filed application may pose a potential conflict and that you need to address a disclaimer requirement for your mark.
