GE has filed a patent infringement complaint against Mitsubishi Heavy Industries, Ltd. (MHI). The complaint includes GE’s patented zero voltage ride through technology system and its bed-frame for wind turbines.
The GE-patented zero voltage ride through technology system helps wind turbines remain connected to the electricity grid when grid voltage drops to zero. The bed-frame supports the weight of the rotor, gearbox, and drive shaft.
GE has 148 issued US patents related to wind energy, and the company said in a release that it believed that there are “multiple areas where MHI’s 2.4 MW wind turbines infringe on GE’s existing patents.”
GE has filed the complaint with the US District Court, Northern District of Texas, Dallas Division, but has also announced plans to appeal the International Trade Commission’s recent ruling saying that GE’s review of the ruling indicated errors that provide grounds for an appeal.
The statement added, “GE believes strongly in the merits of its case against MHI, and will continue to protect its technology in the US and around the world.”
