What is TMCH?

  • tmch
  • TMCH Trademark Clearinghouse was created by ICANN as part of the new gTLD initiative, and is an integral mechanism in domain trademark protection. Official operation began on March 26, 2013.

    The Trademark Clearinghouse is a unique, global repository of authenticated information from trademark holders. All trademark holders are able to register for TMCH before or during the release of new gTLD for protection.

Upon submission and payment of a trademark record, the trademark record and the provided information will be verified in order to determine whether: 1) all provided information is accurate and complete and 2) the trademark meets the eligibility requirements as established by these Clearinghouse guidelines.

Sunrise Services:
Sunrise services allow trademark holders an advance opportunity to register domain names corresponding to their marks either defensively or with a view to exploiting a valuable new web address before new names are made available to the public. New gTLD registries are required to offer a Sunrise period of at least 30 days.

Claims Services:
Claims service follows the Sunrise Period. It is a notification service mandated by ICANN for all new gTLDs – to warn both potential domain name registrants as well as trademark holders (with their marks in the Clearinghouse) of possible infringements.
