TMCH(Trademark Clearinghouse)是在 [[icann|ICANN]] 授权下运营的经验证商标记录集中数据库,被广泛用于新 [[gtld|gTLD]] 的发布。商标持有人向 TMCH 提交商标后,经所有权验证可获得两项保护:一是在 [[sunrise-period|日出期]] 期间的优先注册权,二是在任何参与新 gTLD 中注册完全相同标识时的实时通知(商标声明)。这意味着,每当有人尝试在所有新 gTLD 中注册与其商标完全相同的字符串时,已在 TMCH 注册的品牌所有者将在 24 小时内收到通知。
示例
Nike registered its trademark in the TMCH; when someone tried to register nike.sport during general availability, the registrar displayed a Trademark Claims notice warning the applicant of Nike's existing rights.
