商标交换所(TMCH)是由 [[icann|ICANN]] 建立的中央存储库,旨在新通用顶级域名推出期间保护商标权人的权益。权利持有人向 TMCH 注册经过验证的商标,从而获得两项关键保护:在新 TLD 向公众开放前的 [[sunrise-trademark|日出]] 期间享有优先注册权,以及当有人尝试注册匹配域名时,向注册人和商标持有人双方发送商标声明通知。TMCH 验证需要提交商标证书,可覆盖多个司法管辖区的文字商标,为减少数百个新 TLD 扩展名中的 [[cybersquatting|域名抢注]] 提供了可扩展机制。
示例
By registering its brand in the Trademark Clearinghouse, Nike received advance notice when a third party attempted to register 'nike.photography' during the new TLD rollout, allowing it to block the registration during the claims period.
