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 examiner has refused your trademark application due to a likelihood of confusion with an existing registered mark [Registration No. 2825709], which is a serious issue that may not be fixable.
