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 requires a U.S.-licensed attorney to represent your application because your address is abroad, and the search for conflicting trademarks has been temporarily postponed until this requirement is met.
