A federal judge has overturned seven economic espionage convictions against former Alphabet Inc. (NASDAQ: GOOGL) software engineer Linwei Ding, ruling that prosecutors failed to prove he intended to benefit the Chinese government.
U.S. District Court Judge Vince Chhabria in San Francisco issued the ruling on Thursday, noting that while the evidence supported Ding’s convictions for stealing trade secrets, it did not meet the higher burden required for economic espionage charges.
Convictions and Sentencing Details
Ding, also known as Leon Ding, was convicted in January following an 11-day trial. The judge’s decision vacates the seven economic espionage counts, each carrying a potential sentence of up to 15 years in prison and a $5 million fine.
However, his seven convictions for stealing trade secrets remain intact. These charges carry a maximum penalty of 10 years in prison and a $250,000 fine per count. Ding is scheduled to be sentenced on Sept. 1.
Allegations and Evidence
Prosecutors accused Ding of stealing thousands of pages of confidential information from Google starting around 2022. The allegedly stolen material included details about the hardware infrastructure and software platforms used to train large AI models.
According to court documents, Ding joined Google in May 2019 and began misappropriating data while being recruited by an early-stage Chinese technology company. His lawyers had sought an acquittal shortly after the trial, arguing that prosecutors did not prove the charges beyond a reasonable doubt.
Market Reaction
Alphabet Class A shares closed at $340.67 on Thursday, down 1.17%, while Class C shares fell 1.02% to close at $338.20. The stock movement reflects broader market sentiment rather than a direct reaction to the legal ruling, as the company’s core business operations remain unaffected.
The Justice Department and Google did not immediately respond to requests for comment regarding the judicial decision.
How might this ruling influence the DOJ's strategy in prosecuting future cases involving alleged Chinese-linked intellectual property theft?
Will Alphabet face increased pressure to tighten internal data access controls for engineers working on sensitive AI infrastructure projects?
Could the distinction between trade secret theft and economic espionage set a legal precedent that complicates future espionage charges against tech employees?
