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 USPTO trademark examiner has refused your application due to a potential likelihood of confusion with an existing registered trademark. This is a serious issue that requires careful review.
