A former nanotechnology scientist of Sandia National Laboratories pleaded not guilty to federal charges of selling intellectual property and research to institutes in China.

Jianyu Huang was arraigned last week on 1 count of false statements and 5 counts of federal program fraud as he was accused of sharing information from his post in the Sandia lab’s Center for Integrated Nanotechnologies since 2009. However, the charge was only for theft of federal property and was not for stolen classified information.

He reportedly sold research on nanotech that belongs to the US to government-run Chinese schools like Harbin Institute of Technology and Peking University, claiming them as his own.

The indictment accuses Huang of selling USD 25,000 worth of “materials, equipment, time and work product of the company staff along with intangible property” between 2009 and 2012, on 5 different instances.
