Deadline

November 24, 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 requires you to appoint a U.S.-licensed attorney because your address is outside the United States, and has deferred reviewing the merits of your application while suggesting you consider abandoning and filing a new application due to administrative review of your previous representative.
