Status date

Deadline

September 10, 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 raised a likelihood of confusion refusal with an existing registration and required you to be represented by a U.S.-licensed attorney because your address is outside the United States.
