The Court of Appeal upheld the first instance decision that the patent in suit lacked novelty and inventive step over the prior art. The Court confirmed, following Halliburton v Smith, that despite the fact the parties had reached a confidential settlement and Sony was not involved in the appeal, it was necessary to hear the appeal on its merits as it would not be right to restore a patent which had been held invalid by the court below unless that decision had been shown to be wrong.
