Wobben Properties is taking to court Siemens, companies that have purchased wind turbines from Siemens, companies that install the wind turbines for Siemens and some of Siemens’ customers, for patent infringement.
The patented invention on Enercon's Storm Control technology relates to a method of operating a pitch-controlled wind turbine. Wobben Properties, who owns Enercon's patents, believes Siemens' high wind ride through technology (HWRT) infringes its patent.
Commenting on this, Siemens managing director for UK offshore wind power Clark Macfarlane said: "Siemens is confident that the features and functionalities marketed by Siemens including HWRT do not infringe any valid third parties’ intellectual property rights and intends to therefore continue to defend these court actions.”
A hearing at a High Court in London is scheduled for June.
