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 you need to address a likelihood of confusion refusal, provide your email address, and appoint a U.S.-licensed attorney.
