Status date

Deadline

February 9, 2027

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 refused registration because your application appears to be a duplicate of a prior-filed pending application (Serial No. 98770136).
