The courts have ruled on this before. Not actually using a domain name is not enough reason to be forced to transfer the domain name. Unfortunately, the Court has not ruled on the descriptiveness of the name and that there are also dozens of other trademarks with OK. The Supreme Court has now put an end to all discussion. It rejects the appeal of FuelPlaza. An active website is not necessary. Only one option remains, get in touch with the holder and offer to buy the domain name at a reasonable price.
