Deadline

November 14, 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 issued a refusal because your mark is considered an equation rather than a source indicator, and noted issues with your specimens, service descriptions, required information, and filing fees.
