What happened? A US federal judge has partially overturned the conviction of former Google engineer Linwei Ding. Judge Vince Chhabria threw out all seven economic espionage counts while upholding the seven trade secrets theft convictions. The decision was reported by Reuters and Benzinga on August 20 and 21.
How did the judge reason? Economic espionage requires prosecutors to prove the defendant knew or intended that his conduct would benefit a foreign government. That is precisely where the case fell short, per Chhabria: there was insufficient evidence that Ding "intended or knew his conduct would benefit the government of China". The theft itself — thousands of pages of confidential material on Google's AI hardware and training software, including chip blueprints — stands as legally established.
What was the case about? Ding, a Chinese national, joined Google in May 2019 and, as the jury found, began systematically copying material around 2022 while being courted by a Chinese tech startup. In January 2026, after an 11-day trial, a jury found him guilty on all 14 counts; he had been indicted since March 2024.
What changes for sentencing? A great deal. The overturned espionage counts carried up to 15 years in prison and a $5 million fine each; the upheld theft counts carry a maximum of 10 years and $250,000 each. Sentencing is scheduled for September 1, 2026. Ding's defense said it was gratified by the partial reversal.
Why does the case matter? It was one of the US justice system's showcase prosecutions against alleged AI technology transfer to China. The partial reversal shows how high the evidentiary bar for the espionage charge sits — and is likely to shape future cases involving stolen model and chip secrets.
