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 requires a substitute specimen or an amended filing basis showing proper use of your mark in commerce, along with responses to inquiries regarding your use and the significance of your mark's wording. Additionally, the search of USPTO records found no conflicting marks.
