Sixing Liu was arrested at his home in Deerfield, Ill., in March 2011 and accused of taking restricted military data and presenting it at two conferences in his native China the previous fall.

Liu worked at Space & Navigation, a New Jersey division of New York-based L3 Communications. His attorney says Liu is innocent and simply took his laptop to a conference.

Liu was charged with exporting defense-related data without a license, lying to authorities and possessing stolen trade secrets. Prosecutors say the technology could be used for target locators and other military applications.

The trial is being held in federal court in Newark.
