Deadline

16 Oct 2026

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 requires a U.S.-licensed attorney to represent you due to your foreign domicile, and has refused your current product specimen because it appears to be a digital mockup.
