The International Trade Commission (ITC) has rejected all of GE´s claims against the company in regard to GE’s so-called Zero Voltage Ride Through Patent (US 7,629,705).
While the ITC did rule in favour of a limited infringement on GE’s claims in regard to the so-called Low Voltage Ride Through Patent (US 6,921,985), it targets only full converter wind turbines running pre-2021 versions of software, which Siemens Gamesa no longer sells or imports in the USA. The ITC expressly found turbines running later versions of software did not infringe the ‘985 patent. As these issues continue to be subject to legal actions in a number of jurisdictions the company will not comment further on the matter at this time.
