GE Renewable Energy alters designs for Haliade-X following patent ruling

GE Renewable Energy announced it has filed an application with the court in the Siemens Gamesa Renewable Energy (Siemens Gamesa) patent case for two design-around options for the Haliade-X that seeks to have the court confirm that those designs are not subject to the injunction ruled last month.

The two additional designs cover current and future generations of the the Haliade-X line, with the former concerning its products at 12-14.7 MW ratings. According to the GE Renewable Energy it has redesigned the turbines so that neither the rotating shaft nor the front bearing is in the interior of the rotor hub. It has requested that these designs be made exempt from the injunction against its turbines.

To remind, a lawsuit was filed back in 2020 in which Siemens Gamesa's alleged that GE’s offshore wind turbine Haliade-X infringes two of its offshore Direct Drive technology patents. One concerned the enhancement of direct drive technology (776) and the other concerned its novel structural support arrangement (413).

The resulting legal proceedings led to U.S. District Judge William Young's ruling last month (7 September 2022) in favour of Siemens Gamesa, and prevented GE Renewable Energy from using a specific design for the Haliade-X that has been deemed to infringe the ‘413 patent. It follows a jury's decision back in June that GE Renewable Energy infringed patent 413 and as a result Siemens Gamesa was entitled to a royalty rate of $30,000 per MW GE Renewable Energy's use of infringing turbines.

The Ocean Wind 1 and Vineyard Wind projects have been made exempt from the ruling and will be supplied with GE Renewable Energy's turbine. However, as per the jury's finding previously, for each infringing Haliade-X wind turbine installed GE Renewable Energy shall pay Siemens Gamesa a royalty consisting of $30,000 per megawatt for Vineyard Wind. A royalty rate for Ocean Wind 1 is to determined upon further hearing.
