March 8 Mitsubishi Heavy Industries Ltd.
was ordered on Thursday to pay General Electric Co.
$169 million after a Dallas jury found that the company
had infringed GE's wind-turbine patent.
GE, the largest U.S. maker of wind turbines, sued Japanese
manufacturer Mitsubishi Heavy Industries and two U.S. units in
federal court in Texas in 2010, accusing them of infringing two
patents used in variable-speed wind turbines.
The jury's finding on Thursday relates to a GE patent that
helps wind turbines remain connected to the electricity grid,
even when the grid's voltage drops to zero.
The other patent was ruled invalid by U.S. District Judge
Royal Ferguson on Feb. 10.
Sonia Williams, a spokeswoman for Mitsubishi
Heavy, could not immediately be reached for comment.
Chet Lasell, a spokesman for GE, said: "GE firmly believes
that protecting our intellectual property rights is the
foundation for innovation, investing in high technology
industries and creating high-value jobs."
GE filed the Dallas lawsuit after it lost a case in January,
2010, at the U.S. International Trade Commission (ITC), which
found that Mitsubishi Heavy did not infringe on three GE
After GE appealed the decision, the U.S. Court of Appeals
for the Federal Circuit on Feb. 29 ordered the ITC to reconsider
infringement claims on one of the patents.
The lawsuit is General Electric v. Mitsubishi Heavy
Industries, Mitsubishi Heavy Industries America and Mitsubishi
Power Systems Americas, U.S. District Court for the Northern
District of Texas, No. 10-00276.
