Icescape Ltd v Ice-World International BV and others

Patent – Infringement. The Chancery Division allowed the claimant company's claim for, among other things, a declaration of non-infringement in respect of a patent concerning a cooling member for a mobile ice rink, which the claimant had commenced following allegations of infringement by the defendants. The court held that the priority of the patent had been the date of its filing. Since invalidity was conceded if the patent was not entitled to the priority date of the priority document, the patent had to be revoked.
