The high-stakes world of artificial intelligence just saw its first major criminal reckoning in a San Francisco courtroom. On Thursday, a federal jury found 38-year-old Linwei Ding, also known as Leon Ding, guilty on fourteen total counts—seven for economic espionage and seven for the theft of trade secrets.
This wasn’t just a simple case of a disgruntled employee taking files on his way out the door; it was a systematic, year-long effort to siphon the “brains” of Google’s supercomputing power for the benefit of the Chinese government.
During the eleven-day trial, prosecutors painted a picture of a man living a double life. While Ding was officially drawing a paycheck from Google, he was secretly building a parallel career in the People’s Republic of China.

Evidence showed that between 2022 and 2023, Ding funneled over two thousand pages of highly sensitive data from Google’s internal network into his personal cloud account. He didn’t just stop at data theft; he was reportedly shopping himself around to Chinese tech firms, even positioning himself as a prospective Chief Technology Officer and launching his own AI startup while still employed in California.
The stolen information wasn’t just random code. It focused on the very foundation of modern AI: the hardware and software that allow massive data centers to train large-scale language models.
This included blueprints for Google’s custom Tensor Processing Unit (TPU) chips and specialized networking hardware known as SmartNICs. In pitches to overseas investors, Ding was bold, essentially promising that he could replicate Google’s massive supercomputing infrastructure by modifying the tech he had taken. He even applied for a state-sponsored “talent plan” in Shanghai, explicitly stating his goal was to help China’s computing power reach international standards.
U.S. officials didn’t mince words after the verdict was read. Assistant Attorney General John A. Eisenberg called the move a “calculated breach of trust” that occurred at a pivotal moment in the global AI race.
Meanwhile, the FBI emphasized that this conviction marks the first time AI-related economic espionage charges have successfully gone through a trial, signaling a much more aggressive stance by the Department of Justice toward protecting Silicon Valley’s intellectual property from foreign adversaries.
Ding’s legal journey is far from over. He is scheduled for a status conference on February 3, 2026, where the next steps for his sentencing will be laid out. He faces a staggering maximum penalty: up to ten years for each count of trade secret theft and fifteen years for each count of economic espionage.
While the final sentence will depend on federal guidelines, the message from the Northern District of California is clear: the bridge between Silicon Valley innovation and foreign state interests is now under heavy, high-tech surveillance.
