Enercon expands action against Vestas to Ireland

The patent dispute between Denmark's Vestas and Aloys Wobben, owner of German turbine manufacturer Enercon, continues. In late May, Vestas informed shareholders that it has prevailed for a third time in a case it brought questioning the validity of Aloys Wobben's patent on lightning protection: the German Federal Supreme Court rejecting an appeal by Wobben. This implies parallel proceedings lodged by Enercon against Vestas citing infringement of the patent "will also be rejected or withdrawn," says Vestas. Ten days later, Vestas told shareholders that Wobben has expanded his legal action against Vestas for alleged infringement of a grid connection patent to Ireland. Wobben has already launched challenges against Vestas on the issue in England, Scotland, the Netherlands and Canada (Windpower Monthly, May 2007). "For the time being there are no further comments," says Vestas.
