U.S. District Judge Vince Chhabria in San Francisco partially overturned the conviction of Linwei Ding, a former Google software engineer, on August 20, 2026, after finding the government had not proven the core element of an economic-espionage charge Reuters.
Ding was convicted in January 2026 on 14 counts total: seven counts of economic espionage and seven counts of theft of trade secrets. Judge Chhabria's ruling vacated all seven economic-espionage convictions but left the trade-secrets counts standing Bloomberg Law. The ruling means Ding remains convicted of stealing thousands of pages of confidential information from Google, but prosecutors failed to convince the court beyond a reasonable doubt that he acted with the specific intent to benefit China's government.
The judge determined the evidence was insufficient for a rational jury to conclude Ding knew or intended his conduct would serve the interests of the Chinese state during the relevant period. In written opinions cited by Bloomberg Law, Chhabria characterized Ding's efforts as "ad hoc, disorganized, and feeble." The distinction matters legally: economic espionage requires proof of knowledge and intent to benefit a foreign government, while trade-secrets theft does not.
Ding, identified as a Chinese national by Reuters, had transferred stolen AI-related information as he prepared to depart Google, but the government's case for showing deliberate coordination with Beijing faltered under judicial scrutiny. The ruling reflects a narrow but significant window in how courts interpret the mens rea—the guilty mind requirement—necessary for federal espionage convictions.
At the time of the August 20 ruling, Reuters reported that sentencing remained pending. No fine, restitution amount, or prison term has been announced publicly.
The case underscores ongoing tensions in prosecuting insider threats at major AI labs. While Ding's conviction on trade-secrets counts stands—a serious felony carrying potential prison time—the vacatur of economic-espionage charges signals judicial caution about connecting isolated insider theft to foreign government conspiracy without explicit evidence of coordination or intent. For AI companies and prosecutors alike, the ruling clarifies the evidentiary bar required to prove that a departing engineer's data theft crossed the threshold from corporate crime into national-security offense.
