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 your trademark application due to a potential likelihood of confusion with an existing registration for 'CDX' and requires an acceptable substitute specimen showing your mark in actual commercial use.
