Status date

Deadline

Oct 31, 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 you to be represented by a U.S.-licensed attorney, and the official search for conflicting trademarks has been deferred until this requirement is met.
