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 requires you to have a U.S.-licensed attorney represent your application because your address is outside the U.S. and your previous representative was suspended, while also temporarily deferring the search for conflicting trademarks until this requirement is met.
