Can I register a domain in Sunrise that includes my trademark?
No, this is not possible. In the Sunrise, the domain name should exactly match your trademark or one of its labels. If you own a trademark 'Apple', you can register apple.forum but not applehelp.forum (that would require the trademark "Apple Help").
For a registration of a domain that includes your trademark (but is not an exact match), you will have to wait until the Sunrise is over and register the domain in one of the phases following the Sunrise phase. Refer to the launch calendar to investigate your options. You may be able to register the domain in Landrush or Early Access Program phases.
You can also submit your domain as a pre-registration. Openprovider will then send your application to the registry as soon as the General Availability opens.
