USPTO registered the CABLE HOUND trademark for a device used to locate underground cables. The device comprises a tone source, tone probe, and receiver unit. This is a standard trademark registration notice providing IP protection.

For most organizations, no action is required. Companies manufacturing or selling underground cable locator devices or similar electronic testing equipment should verify their product names do not conflict with the CABLE HOUND mark. Businesses developing competing products in Class 9 (scientific/electrical devices) should conduct trademark clearance searches before adopting similar names.
