Free Trademark Search

U.S. Trademark Search
This trademark database provides access to the same text and image database of trademarks as currently provided to examining attorneys at the US Patent and Trademark Office via the X-Search system. This database is updated daily on Tuesdays through Saturdays and contains those trademarks that are federally registered or that are pending (applications undergoing examination at the USPTO). The fact that a mark is not present in this database does not necessarily mean that the mark is not currently being used as a trademark. Information on applications and registrations that were inactive prior to 1984 are generally not available on this database.

International Trademark Search
The so-called Madrid Express database by the World Intellectual Property Office allows trademark search for marks internationally filed under Madrid Protocol via any of the member states. Boolean search available. Includes all international registrations that are currently in force or have expired within the past six months. This database also includes data relating to international applications and subsequent designations that have been received by the International Bureau but have not yet been recorded in the international register of marks.

Japanese Trademark Search
Japan Patent Office (JPO) provides public access to this Japanese Trademark Database or the Industrial Property Digital Library (IPDL) allowing trademark search in English. Pre-examined trademarks and registered trademarks in JPO are searchable using English key words.
