Between 2002 and 2007, Ji Wang worked on an $11.4 million  Defense Advanced Research Projects Agency (DARPA) project to develop high-powered optical-fiber lasers with military applications, and he later stole proprietary manufacturing files with the intent to commercialise the technology in China. The jury found him guilty of two counts of economic espionage, one count of theft of trade secrets, and attempted versions of both charges, underscoring the U.S. government’s focus on prosecuting illicit transfer of critical dual-use technology.
