A former research scientist was convicted of charges he stole trade secrets from Michigan''s Dow Chemical Co. and sold them to companies in China, the Associated Press reports. After a three-week trial, a federal jury in Baton Rouge convicted Wen Chyu Liu, 74, also known as David Liou, of conspiracy to commit trade secret theft and perjury. Liu worked at the Midland, Mich.-based chemical giant''s facility in Plaquemine, La., before he retired in 1992. Prosecutors said he conspired with at least four other Dow employees in Louisiana and Germany to sell confidential information about the company''s production of a polymer called chlorinated polyethylene, which is used in automotive hoses, vinyl siding and other products. Liu bribed one employee at the Plaquemine facility with $50,000 in cash in exchange for Dow''s process manual and other information, according to prosecutors. Prosecutors said Liu, who was sued by Dow, lied under oath during a deposition for the civil case when he denied making arrangements for a coconspirator to travel to China to meet with a company''s representative. The Houston resident faces a maximum sentence of 15 years in prison. His sentencing date wasn''t immediately set.
