Trademark holders only
Owners of a registered trademark have the possibility to apply this mark at TradeMark ClearingHouse. It's important your mark application has been entirely completed before you apply at TMCH.
Registration = necessary
Registering your trademark at TMCH is necessary if you wish to register your trademark under a new gTLD during the sunrise of that new gTLD.
TMCH will check whether the info you supplied about your mark is correct. Once registered, you'll benefit from the free 'claims' service: this service will send you a warning when someone else tries to register your mark under such a new TLD.
Signing in already possible
Signing in is already possible thanks to the so called “early bird period”. This means you can already register your trademark at TMCH but your registration will only be activated once the first extension is released. Let's say you sign in today at TMCH for a period of 3 years and the first extension is released mid July 2013. Your registration at TMCH will be active from mid July 2013 until mid July 2016.
