Linwei Ding, a former software engineer at Google, has been convicted of stealing trade secrets related to artificial intelligence (AI) for the benefit of China. The US Department of Justice announced that a federal jury found the 38-year-old guilty on seven counts of economic espionage and seven counts of theft of trade secrets following an 11-day trial in the US District Court in the Northern District of California.
Ding's actions, which took place between May 2022 and April 2023, involved the theft of more than 2,000 pages of confidential information from Google's network. He uploaded this sensitive data to his personal Google Cloud account while simultaneously working with two technology companies based in China. According to court documents, Ding's affiliations included a startup he founded in 2023, which focused on AI and machine learning.
The conviction is particularly notable as it marks the Justice Department's first successful prosecution related to AI-focused economic espionage. US Attorney Craig Missakian emphasized that Silicon Valley remains at the forefront of AI innovation and that such theft poses risks to national security and economic stability.
Evidence presented at the trial indicated that Ding sought to gain a competitive advantage for the companies he collaborated with by leveraging Google's proprietary technology. He allegedly claimed to potential investors that he could create an AI supercomputer based on the stolen technology. Furthermore, Ding applied to a talent plan sponsored by the Chinese government, aiming to bolster the country’s computing infrastructure.
The FBI has underscored the implications of Ding's theft, asserting that the misuse of advanced AI technology threatens the US's technological edge. FBI Special Agent Sanjay Virmani stated, "This conviction reinforces the FBI's steadfast commitment to protecting American innovation and national security.".
Ding’s attorney argued that Google failed to adequately protect its information, suggesting that the documents were too widely accessible to be classified as trade secrets. However, the jury's decision indicates a strong stance against such rationalizations in cases of economic espionage.
The former engineer's trial revealed a pattern of deceit, including using his company access badge to mislead colleagues about his whereabouts while working on his startup in China. Ding downloaded the stolen trade secrets shortly before resigning from Google in December 2023, creating a timeline that suggested premeditated intent to exploit the company's resources.
As Ding faces a potential maximum sentence of 10 years for each count of theft of trade secrets and 15 years for each count of economic espionage, the case serves as a warning to others about the consequences of stealing sensitive technology. His next court appearance is scheduled for February 3, 2026.
The Ding case highlights the growing concerns over economic espionage, particularly in the technology sector, where the race for AI supremacy is intensifying. As US companies continue to innovate, the federal government is committed to ensuring that trade secrets remain protected from foreign adversaries seeking to gain an unfair advantage.
This landmark case not only reflects the serious legal repercussions of corporate espionage but also underscores the importance of safeguarding intellectual property in the rapidly evolving field of artificial intelligence.
