W L Gore & Associates GmbH v Geox SPA

W L Gore & Associates GmbH v Geox SPA

The Court of Appeal upheld the trial judge's construction of the patent claims. 'Mid-sole' and 'filler layer' were not limited as Gore contended; the filler layer need not have a specific thickness or function beyond being a layer between the insole and membrane. 'Unitary upper assembly' required a pre-prepared, free-standing assembly, not merely components held together in a mould. Gore's arguments based on the drawings and technical distinctions were rejected. The appeals and cross-appeals were dismissed.
