Vestas Wind Systems, additional patent disputes with Enercon GmbH

In Stock exchange announcement Nos. 27/2005 and 30/2005, Vestas informed that Enercon GmbH had taken out a writ against Vestas claiming that a patent owned by Enercon GmbH had been infringed. Enercon GmbH is now claiming that the Vestas Group may be infringing additional patent rights. The claim concerns patents related to electricity grid codes. If possible negotiations with the counterparty do no lead to a result, the case is expected to be brought before the courts.
