U.S. District Judge Vince Chhabria in San Francisco overturned half of Linwei Ding's conviction on August 20, 2026, ruling that prosecutors failed to prove a critical element of economic espionage: that the former Google software engineer intended or knew his conduct would benefit the government of China Reuters.
Ding, a Chinese national and former Google engineer, was originally found guilty in January 2026 after an 11-day trial on 14 counts total—seven counts of economic espionage and seven counts of theft of trade secrets. The judge's ruling eliminates the espionage convictions but leaves the seven trade-secret theft counts in place, supported by evidence that Ding stole thousands of pages of confidential information from Google.
In his decision, Judge Chhabria stated: "There was insufficient evidence Ding intended or knew his conduct would benefit the government of China." This finding is critical to economic espionage law, which requires prosecutors to demonstrate that a defendant acted with knowledge or intent to benefit a foreign state—a higher bar than simple trade-secret theft.
Prosecutors alleged that Ding stole confidential materials and intended to benefit two Chinese companies, not the Chinese government itself. While that conduct satisfied the elements of theft of trade secrets, it did not meet the statutory requirements for economic espionage under federal law. Each economic espionage count carried a maximum 15-year prison term and $5 million fine; each trade-secret theft count carried a maximum 10-year term and $250,000 fine Reuters.
Google was not charged in the case and said it cooperated with law enforcement throughout the investigation.
The ruling underscores the legal distinction between benefiting private foreign entities and benefiting foreign governments—a distinction that has shaped prosecutions in the AI and advanced-technology sectors. While Ding's trade-secret convictions remain, the overturning of the espionage counts may narrow prosecutors' charging strategy in similar cases involving technology transfer to Chinese companies.
Sentencing and the final penalty imposed have not yet been announced.
