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 perceived likelihood of confusion with existing registered trademarks. We are evaluating these citations to determine the best path forward.
