In November 2005 Vestas Wind Systems A/S stated that Enercon GmbH had claimed that the Vestas Group might be infringing patent rights for electricity grid codes.
The owner of Enercon GmbH, Mr Aloys Wobben, has now taken out a writ against Vestas-Celtic Wind Technology Limited claiming the infringement of these patent rights in England and Scotland. The mentioned company is 100 per cent owned by Vestas Wind Systems A/S. It is the opinion of the management of Vestas Wind Systems A/S that Vestas Wind Systems A/S is not infringing the patent rights of Aloys Wobben, which has been confirmed by an evaluation of the patent rights made by independent patent experts.
