Chinese American Couple Charged With Theft of Trade Secrets From Ohio Hospital Masood Farivar A Chinese American couple has been arrested and charged with stealing scientific trade secrets from a children's hospital in Ohio in the latest federal prosecution aimed at clamping down on China's alleged theft of American intellectual property. The couple -- Yu Zhou, 49, and Li Chen, 46 -- worked in separate labs at the Nationwide Children's Hospital in Columbus, Ohio, for 10 years, stealing proprietary research for use in personal business ventures, law enforcement officials announced Monday. The purloined exosome-related trade secrets play a key role in the diagnosis and treatment of a range of pediatric medical conditions, including liver cancer and a condition found in premature babies, according to a 27-page federal indictment. .
