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 application faces a likelihood of confusion refusal and potential conflicts with earlier-filed applications, while also requiring updates to your goods descriptions, entity details, email address, and representation by a U.S.-licensed attorney.
