Linwei Ding, who joined Google in 2019, is guilty of seven counts of economic espionage and seven counts of trade secret theft following an 11-day trial. The verdict came after prosecutors presented evidence that Ding uploaded proprietary information to his personal cloud account between May 2022 and April 2023, then used that knowledge to establish competing ventures in China.
Stolen materials included more than 2,000 pages of confidential documentation detailing Google’s AI supercomputing infrastructure. Ding accessed proprietary information about the company’s tensor processing unit and graphics processing unit system technologies, orchestration software designed for managing large-scale AI workloads and SmartNIC networking technology.
While employed at Google, Ding maintained undisclosed affiliations with two China-based technology companies. He negotiated a position as chief technology officer at one firm and later founded Shanghai Zhisuan Technology, where he worked as chief executive officer. Prosecutors said Ding pitched potential investors by claiming he could replicate Google’s AI supercomputing capabilities.
Federal prosecutors said that evidence showed Ding applied to a Shanghai government-sponsored talent program. His application indicated that he “planned to ‘help China to have computing power infrastructure capabilities that are on par with the international level.'”
The trial included testimony about Chinese government initiatives designed to recruit technical talent. “The jury heard evidence pertaining to the PRC government’s establishment of talent plans to encourage individuals to come to China to contribute to the PRC’s economic and technological growth,” the Department of Justice said in a statement.
Prosecutors argued that Ding intended to assist entities controlled by the Chinese government. “The evidence at trial also showed that Ding intended to benefit two entities controlled by the government of China by assisting with the development of an AI supercomputer and collaborating on the research and development of custom machine learning chips,” Justice said.
Ding took steps to conceal his activities from Google. He never disclosed his business relationships with the Chinese firms or reported travel to China. Court evidence showed he asked a colleague to scan his employee badge at the workplace periodically, creating the false impression that he remained in the United States and was reporting to the office.
Google initiated an internal investigation after detecting irregularities. Ding was indicted in March 2024 after prosecutors said he lied during the company’s inquiry and failed to cooperate with investigators. He was subsequently arrested in California.
Each count of economic espionage carries a maximum prison sentence of 15 years, while each trade secret theft count carries a maximum of 10 years. The court has not yet announced a sentencing date.
