Man Gets 15 Years’ Prison for Stealing DuPont Secrets

Walter Liew, a California businessman who is the first person in the U.S. convicted by a jury of economic espionage, was sentenced to 15 years in prison for stealing DuPont Co. trade secrets to help a Chinese company build a manufacturing plant.

U.S. District Judge Jeffrey White in Oakland, California, issued the sentence today after prosecutors sought a prison term of at least 17 years. He said Liew’s conduct was “a virtual white-collar crime spree” and “a loud message has to go out” to those who would sell U.S. trade secrets.
