Status on lightning protection patent dispute with Enercon GmbH, Aloys Wobben   

In stock exchange announcements Nos. 27/2005 of 19 August 2005, 30/2005 of 16   
September 2005, 39/2005 of 22 November 2005, 22/2006 of 5 April 2006, 12/2007 of
2 April 2007 and 15/2007 of 12 April 2007, Vestas Wind Systems A/S has informed 
of various patent disputes with Mr Aloys Wobben/Enercon GmbH.                   

In the case trying validity of Aloys Wobben's patent on lightning protection,   
Vestas Wind Systems A/S has prevailed in three instances as the German Federal  
Supreme Court has now rejected the appeal. This implies that the parallel       
infringement proceedings regarding this patent will also be rejected or         
withdrawn.                                                                      

For the time being, there are no further comments to the case.
