Deadline

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 maintained refusals based on descriptiveness and likelihood of confusion with existing registrations, and denied your alternative claim of acquired distinctiveness.
