Patent – Practice. The Intellectual Property Enterprise Court ruled on a number of applications made in respect of a claim concerning a patent for a snap-in insert which was used in display panels for shops. Among other things, it held that the English courts had jurisdiction over the dispute; granted the claimants' application for an order, under CPR 6.15(1) and (2) that good service was deemed to have been achieved by delivery to the defendants of a copy of an unsigned claim form; and dismissed a claim against one of the defendants where there were no arguable pleaded grounds on which the claimants could allege that that defendants had infringed the patent.
