The "Teesside Airport" trademark is owned by Chris Joseph who also (interestingly) owns the dormant companies: "Teesside Airport Limited", "Teesside International Airport Limited", "Tees Valley Airport Limited" and "Tees Valley International Airport Limited". Owning these companies will strengthen the argument that he has genuine rights to the trademark.
Really? Setting up and "running" a dormant Ltd. costs a few quid annually, so it is not really much different from registering a domain.
