February 12, 2010 - General Electric Co., which has 148 issued U.S. patents related to wind energy, has sued Mitsubishi Heavy Industries Ltd. for patent infringement of two of those patents.

One of the patents-in-suit relates to the base frame that supports the rotor's weight, and the other concerns a way of keeping the turbine connected to the electricity grid even when the voltage drops.

The suit was filed in the United States Federal District Court for the Northern District of Texas.
