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 examiner requires you to appoint a U.S.-licensed attorney because your previous attorney is under review, and has deferred the search for conflicting marks while suggesting you consider abandoning the application and filing a new one, which is a serious issue.
