Colorado Trademark Search | Secretary of State

The Colorado trademark search is a tool available on the Secretary of State website that enables users to research any trademark registered with the state. The portal allows users to search the business database generally or perform an advanced trademark to narrow the results.

Registering a trademark in Colorado does not protect it on a federal level.^[1] Registrations are valid for a period of 5 years and must be renewed within 180 days of expiration.^[2] Expired trademarks cannot be renewed.
