Earlier this year, a Northern California grand jury had indicted the Pangang Group and others for conspiracy to commit economic espionage and other crimes including conspiracy to steal trade secrets.
The case against Pangang alleged that the company, which is situated in Sichuan, China, had been working with a California businessman and others to obtain several valuable trade secrets from chemical giant DuPont. Prosecutors argued that they had notified Pangang properly through a U.S. company, Pan America that was Pangang’s agent.
However, the court ruled on Monday that there was insufficient evidence to prove that Pangang exercised sufficient control over Pan America for the latter company to qualify as agent of the former. In the same case, California businessman Walter Liew and his wife Christina, also face charges of conspiracy to commit economic espionage. Liew, who is a U.S. citizen, is alleged to have paid former DuPoint engineers for assistance in designing chloride-route titanium dioxide. Currently, DuPont is the world’s largest producer of the white pigment which is used in a variety of products including plastics, paint, and paper. Both Liew and his wife have pleaded not guilty to the charges against them.
