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 your trademark is too similar to existing registered marks, resulting in a refusal based on likelihood of confusion.
