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 refused your trademark registration due to a likelihood of confusion with an existing registered mark. This is a serious issue requiring our review.
