Trade mark – Infringement. The Intellectual Property and Enterprise Court held that a word mark 'CASPIAN', registered in respect of restaurants and related services had been invalidly registered, pursuant to s 5(4)(a) of the Trade Marks Act 1994 and art 4(4)(b) of the Trade Mark Directive. Another mark had been validly registered, neither of the trade marks had been infringed by the defendants and the claimant's action for passing off failed.
