The California trademark search is a free tool provided by the Secretary of State that enables users to access available information on state-registered trademarks and service marks. The service was introduced in 2019 as an expansion of bizfile California and can be used to both research mark availability and investigate records.[1]
Trademark registration is valid for five years and renewal must occur within six months of expiration.[2] There is no limit on the number of renewals.[3]
