Wenfeng Lu was seemingly living the American dream—a comfortable life in Irvine, California, with his family and a career in medical device research and development.

Yet Lu’s secret goal was to use trade secrets stolen from his employer to strike it rich in his native China. However, thanks to an FBI investigation, his plan was thwarted, and Lu is now serving a 27-month prison sentence.

Lu worked for several different U.S. companies, all of which developed high-tech medical equipment, such as clot retrieval tools and balloon-guide catheters. In each job, Lu signed a non-disclosure agreement for his research and development work.
