*Environmental Defence Systems Ltd v Synergy Health plc and others

Patent – Infringement. The claimant company owned a European patent for a method of manufacturing barrage units for flood defence. It brought proceedings, claiming that the defendants had infringed the patent. The Intellectual Property Enterprise Court considered, as a preliminary issue, whether there was an inventive step in the activities to which elements of its claim related. The court held that there was no inventive step, and hence the claim would be dismissed.
