Ex-Dow scientist sentenced to five years in prison for stealing trade secrets

January 17, 2012

BATON ROUGE, La. — A former Dow Chemical Co. research scientist was handed a five-year prison sentence for stealing trade secrets and selling them to Chinese companies, Bloomberg reported.

In February 2011, Wen Chyu Liu, also known as David W. Liou, was convicted of perjury and conspiring to steal Dow trade secrets.

The 75-year-old scientist, who worked for Dow from 1965 to 1992, had access to secrets related to the manufacture of chlorinated polyethylene or CPE, used in the making of vinyl siding, electrical cable jackets and industrial hoses.

“Liu traveled extensively throughout China to market the stolen information, and evidence introduced at trial showed that he paid current and former Dow employees for Dow’s CPE-related material and information,” the U.S. Justice Department said in a statement.
