The UDRP only allows you to take a domain for trademark infringement if:
a) the domain name is identical or confusingly similar to a trademark or service mark in which the complainant has rights; and
b) he/she has no rights or legitimate interests in respect of the domain name; and
c) the domain name has been registered and is being used in bad faith
