DuPont wins patent case
The most recent round in the Guenoun/Marthens patent litigation has resulted in a victory for the companies arguing that the patents are invalid. On 29 March the French Court of Appeal upheld the earlier decision that the French Guenoun patent should be revoked, agreeing with the arguments presented by Cuirs de Futur (formerly SOCOP), together with DuPont and Boot Shop. The decision to revoke the patent means that both French infringement actions brought against Cuirs de Futur and DuPont therefore fail.
Mr Jeff Turner, acting as spokesman for DuPont, said: "We had always believed the Guenoun patent was invalid but it has taken a long battle through the courts to get the decision showing we were right. We will work to achieve the same result in the cases before the Italian courts and in the European Patent Office".
