Status date

Deadline

November 25, 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 examiner has temporarily deferred the review of your application due to an administrative review, and requires you to appoint a U.S.-licensed attorney because your address is outside the United States.
