The Trademark Clearinghouse is a global repository that stores authenticated trademark information. Registering trademarks in the Clearinghouse allows companies to participate in Sunrise periods for new generic top level domains, where they can register matching domain names before they become publicly available. It also provides the Trademark Claims service, which notifies both potential registrants and trademark holders of possible infringements. While there is no first come, first served policy, identical trademarks from different owners can be stored as long as they are valid. Registering trademarks for multiple years provides protection as new gTLDs are launched and ensures companies only have to complete the registration process once.
