Office Action checkout

Owner

Signal Layer, Inc.

Status date

Jun 12, 2026

Deadline

12 Sep 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 issued a refusal because it views 'SIGNAL LAYER' as a descriptive term for your services, and it also requires more specific descriptions for the services listed in your application.
