A California engineer has been found guilty of stealing DuPont’s recipe for producing white pigment and selling it to a state-owned Chinese company. As Bloomberg News reports, a federal jury in San Francisco this week found consultant Martin Liew guilty of 22 counts of economic espionage, trade-secret theft, witness tampering, and making false statements. Liew, 56, was found guilty of selling the secrets to Pangang Group, a China-based company that is building a new plant to produce titanium dioxide — a white pigment used in a wide range of products, including paper, whitening chemicals, and Oreo filling.
