GE files patent infringement complaint against MHI

General Electric Company (GE) announced today that it has filed a patent infringement complaint against Mitsubishi Heavy Industries, Ltd. (MHI).

In the complaint GE alleges that MHI infringes on two additional patents.? Patents infringed by MHI include:

• GE’s patented zero voltage ride through technology system that helps wind turbines remain connected to the electricity grid when grid voltage drops to zero.??
• GE’s patented bed-frame for supporting the weight of the rotor, gearbox and drive shaft.

GE believes that there are multiple areas where MHI’s 2.4 MW wind turbines infringe on GE’s existing patents.
