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 registration due to a likelihood of confusion with existing registered marks and requires an acceptable substitute specimen showing proper use in commerce for your Class 5 goods.
