The Justice Department says China's largest wind turbine company and three people are accused of stealing trade secrets from a U.S. software company.
An indictment handed up in Wisconsin alleges Sinovel Wind Group and the three individuals stole proprietary wind turbine software technology from Devens, Mass.-based AMSC, formerly known as American Superconductor Inc., cheating the American company out of more than $800 million.
It alleges the defendants stole software that was developed in Wisconsin by downloading it from an AMSC computer in Middleton, Wis., to a computer in Austria.
AMSC says the stolen software was used in four Sinovel turbines that have been installed in Massachusetts.
None of the individual defendants is in custody. The Justice Department says two of them are Sinovel employees who live in China, while one who now lives in Serbia formerly worked for an AMSC subsidiary in Austria.
