Press Release: Düsseldorf Regional Court dismisses action brought by Wobben Properties against Light:Guard

A decision has been reached in the patent case between Wobben Properties GmbH and Light:Guard GmbH. The Düsseldorf Regional Court dismissed the action brought by Wobben Properties GmbH, which manages patents for wind turbine manufacturer Enercon, at first instance. The dispute concerned European patent EP 1 984 622 B1, which relates to transponder-based Aircraft Detection Lighting Systems (ADLS) on wind turbines.

The aim of the court proceedings was to clarify whether the light:guard system uses a technology that is covered by the patent claim of Wobben Properties GmbH. The District Court of Düsseldorf denied that the system used by Light:Guard GmbH infringes the patent claim. An out-of-court settlement prior to the lawsuit could not be reached. “We are pleased that the court, after examining our technology, came to the conclusion that we have not committed any infringement. We also hope that this clarification will lead to an even better and more intensive cooperation with the Enercon Group,” explains Willi Lehmann, CEO of Light:Guard.
