The AI Theft Verdict That Split in Two
The valuable asset was not a chatbot answer, but the engineering behind it.
Read in slides1. An engineer with valuable access
Linwei Ding, also known as Leon Ding, worked at Google on technology associated with advanced computing for artificial intelligence. His position provided access to confidential technical material. The later criminal case concerned the movement of that information and his outside business activities, placing a dispute over employee conduct inside a period of intense international competition over AI infrastructure.
The valuable asset was not a chatbot answer, but the engineering behind it.
2. Files leave the company’s system
Prosecutors presented evidence that Ding uploaded confidential Google material to a personal account during 2022 and 2023. The information concerned technology supporting AI computing, rather than simply public research papers. The case therefore required examination of specific protected material and what he did with it, not an assumption that every engineer’s interest in another business amounted to theft.
The question was what crossed the boundary—and with whose permission.
3. The outside ventures
Evidence linked Ding to Chinese technology ventures while he remained employed by Google. Prosecutors argued that his activities and presentations showed a plan to use the material outside the company. The legal issues were more exacting than the broad political story: different criminal charges required proof of different intentions and benefits at relevant points in time.
One set of events would be judged under two different legal tests.
4. The January verdict
In January 2026, a federal jury convicted Ding on seven counts of trade-secret theft and seven counts of economic espionage. The verdict attracted attention as an AI security case, but it was not the last ruling. Post-trial motions required the judge to assess whether the evidence legally supported all the conclusions the jury had reached.
Fourteen guilty findings were about to face another examination.
5. The distinction inside the charges
Economic espionage required proof concerning intended or known benefit to a foreign government, beyond the elements of trade-secret theft. A connection with a Chinese company was not by itself sufficient to establish that government-related element. The timing of Ding’s knowledge or intention became central to the court’s review of whether that part of the prosecution had been proved.
A foreign company and a foreign government were not interchangeable legal facts.
6. The August reversal
On 20 August 2026, Judge Vince Chhabria granted acquittal on the economic espionage counts because the evidence did not sufficiently establish the required government-benefit element under the theory tried. The trade-secret theft verdicts remained. The court had separated proof that company material was stolen from proof that its theft was intended to benefit a foreign government.
The headline conviction had split into surviving verdicts and acquittals.
7. What remained after the order
The August order left Ding with the trade-secret theft verdicts while removing the economic espionage convictions. The same file transfers had produced different legal outcomes because the offences required different proof. The courtroom’s ending had become more complicated than the original announcement, with the government-benefit question changing what could legally be concluded from the evidence presented at trial.
The files mattered. So did the legal boundary the headlines nearly erased.
