The United States Court of Appeals for the Seventh Circuit addressed the case of Hanjuan Jin, who was convicted of theft of trade secrets under the Economic Espionage Act but acquitted of economic espionage. Jin, a naturalized American citizen of Chinese descent with advanced degrees in physics and computer science, worked as a software engineer at Motorola until 2007, primarily on the iDEN telecommunications system. During a medical leave, she sought employment with a Chinese company, Sun Kaisens, and upon her return to the U.S., downloaded thousands of proprietary Motorola documents related to iDEN before purchasing a one-way ticket to China.

The government’s case hinged on three specific documents, arguing that Jin intended to use them for personal economic benefit, evidenced by her substantial cash reserves and travel plans. Jin contended that the downloaded information did not meet the statutory definition of a trade secret, which requires that the information possesses independent economic value from being kept confidential. Additionally, she argued that she neither intended nor knew her actions would harm Motorola, which she claimed was not significantly impacted by the theft as iDEN was becoming outdated yet still had numerous customers. The court's analysis focused on the legal definitions of trade secrets and theft of trade secrets, including the economic harm element necessary for her conviction.

Motorola treated the iDEN technology as a trade secret, restricting its sale and service to itself and its licensees. The defendant contended that the declining commercial value of iDEN meant that theft could not harm Motorola, arguing there was no economic benefit from keeping the technology secret. However, the defendant, as an engineer familiar with iDEN, would have known that if she had taken the iDEN documents to China, Motorola would need to alert customers about potential privacy risks and incur expenses for countermeasures. Additionally, her new employment with a company servicing the Chinese military raised concerns that she might share the stolen information, potentially enabling the Chinese government to compromise iDEN networks.

Motorola had invested in precautions to maintain the secrecy of iDEN, driven by the fear of adverse consequences if the technology were public. The secrecy provided Motorola with a temporary monopoly, which, while diminishing due to technological advances, still generated significant profits that competition could undermine if the technology became public. Although the defendant claimed her intent was solely to use the documents as study aids, the implication was that her enhanced knowledge of iDEN could benefit her career and possibly assist foreign entities in duplicating or hacking the system. 

The legal perspective indicated that the government does not need to demonstrate actual economic loss resulting from the theft; it is sufficient to show that the information retains potential independent economic value as long as it remains confidential. The case referenced, United States v. Lange, illustrated that information could qualify as a trade secret even if it might be obtainable through legal means like reverse engineering, highlighting the importance of maintaining competitive advantages through secrecy.

Lange, a former employee, attempted to sell information necessary for certifying components identical to those certified by RAPCO. The legal precedent from United States v. Chung illustrates that even without immediate profit loss, the theft of trade secrets can be actionable if it reveals valuable problem-solving methods that competitors might exploit. A hypothetical scenario involving a stolen iDEN technology illustrates that economic value can exist even if not immediately monetizable, as it could harm Motorola's reputation for secrecy and security against competitors.

In the case at hand, the district judge acquitted Lange of economic espionage—requiring intent to benefit a foreign entity—due to insufficient proof beyond a reasonable doubt. However, he increased her offense level by two under sentencing guidelines for misappropriating a trade secret, which he determined by a preponderance of evidence, allowing such findings to influence sentencing. This adjustment raised her total offense level to 28, leading to a guideline range of 78 to 97 months. Ultimately, she received a 48-month sentence, significantly lower than the guideline range, attributed to her poor health and family circumstances. Additionally, the judge surprisingly reduced her offense level for acceptance of responsibility, despite her not guilty plea and trial. The ruling was affirmed.
