Daniel Alexander QC and James Abrahams represented the Claimant Armour and Richard Meade QC and Robert Smith represented Leisuretech Electronics in the trial held in October 2008. Armour sought revocation of Leisuretech’s patent for a system for the provision of stereo sound to different rooms from a single source using a particular type of ‘Cat 5 cable’. Armour claimed that the patent was obvious over the common general knowledge. It was accepted by both parties that if the patent was valid then Leisuretech would be liable for infringement. The Judge held that the patent was invalid as it lacked an inventive step.
