Status date

Deadline

July 28th, 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 has refused your application because your mark is too similar to existing registrations, you need to disclaim a descriptive word, and you must provide a valid physical business address.
