Hanjuan Jin, a software engineer formerly employed by Motorola, was sentenced to four years in prison on Wednesday for stealing trade secrets from the company. According to the Wall Street Journal, Jin had perpetrated the crime on behalf of Sun Kaisens, a Chinese military contractor specializing in telecommunications technology. Jun was caught in 2007 after being stopped by customs officials as she attempted to leave the US on a one-way ticket to China. Authorities discovered she was carrying more than 1,000 Motorola documents along with classified Chinese military documents and $30,000.

Jin had been convicted of three counts of trade secret theft back in February, but the sentencing only happened this week. Upon hearing her sentence, Jin reportedly said she was "so sorry for what happened." US District Judge Ruben Castillo, however, stressed the importance of protecting trade secrets, even going so far as to say that "The most important thing this country can do is protect its trade secrets." Jin was also fined $20,000, and will be forced to wear an electronic monitoring device at her home until her sentence begins on October 25th.
