Status date

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 requires your application to be represented by a U.S.-licensed attorney due to your international address, and has temporarily deferred the search for conflicting trademarks pending these updates.
