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 you have a potential prior-filed application conflict, need to submit a new drawing and updated description, and must add a disclaimer for a descriptive word.
