Patent clash takes a new twist

Vestas warns its shareholders that its patent battle with Enercon may be deeper and broader than anticipated. It says Enercon's additional claim "concerns patents related to electricity grid codes, however it may also concern other issues." Enercon counters that "although much has been said" it has not threatened another writ. "There is no basis for this whatsoever," although Vestas "may have interpreted the situation differently," it says. In August, Vestas said that Enercon's patent claim was "not lawful." Discussions between the two have ground to a halt for now, says Knottnerus-Meier.
