Power technology firm alleges espionage
American Superconductor Corp. alleged that a Chinese maker of wind turbines hired a former employee to steal its technology. The Devens company registered a complaint with officials in China and is seeking criminal complaints against Sinovel Wind Group. The former employee was arrested in Austria in July and charged with economic espionage. The former staffer stole software source code used to control turbines and passed it to Sinovel, the company said. Sinovel has denied those claims.
