Office Action checkout

Owner

William E Kelleher

Status date

Aug 5, 2026

Deadline

11 Jul 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 an existing trademark registration for 'DIA', which could cause consumer confusion.
