Status on patent disputes with Enercon GmbH, Mr Aloys Wobben

Randers, 16 January 2008. In previous company announcements Vestas Wind Systems A/S has informed of various patent disputes with Enercon GmbH/Mr Aloys Wobben. Mr Aloys Wobben claims that Vestas Wind Systems A/S infringes various patents; primarily in the area of grid connection, but also in other technical areas.

As mentioned in previous announcements, all cases regarding other technical areas have been decided in favour of Vestas.

In the area of grid connection, Mr Aloys Wobben has initiated court proceedings in Holland, England and Scotland, Canada and Ireland as previously announced.

In part of the case regarding the Dutch market, judgment was handed down by the Dutch District Court of The Hague on 16 January 2008 acquitting Vestas.

The case concerned the following patens owned by Mr Aloys Wobben:

• Voltage control I (EP 1 040 564)
• Voltage control II (EP 1 164 691)

The District Court has denied Mr Aloys Wobben’s claims and ruled both patents invalid.

At the moment, it is not known whether Mr Aloys Wobben will appeal the decision.

Vestas’ management is very satisfied with the decision, which is in accordance with the ruling made by the British High Court on 14 November 2007, as mentioned below.

The case regarding the third and last patent (frequency EP 1 282 774) in Holland will be heard at the District Court in The Hague on 8 February 2008, and the decision is not expected until later this year.
