Big Tech Apple Apple adds more allegations to its trade secrets lawsuit against OpenAI It claims a laptop proves that a former employee accessed and used proprietary files for the AI company.

As part of a push to obtain expedited discovery, Apple filed a support document that revealed information found on a MacBook laptop used by a former employee after he began working at OpenAI. The filing centers on former Apple senior system electrical engineer Chang Liu. Apple’s initial forensic investigation of a laptop Liu used after leaving the company alleges that the former employee knew he had access to Apple’s third-party cloud storage and used it to download "dozens of confidential Apple files," including a circuit schematic.

Apple further claimed that Liu used that schematic to run simulations in the course of his work for OpenAI. It claimed the laptop revealed previously unknown instances of stolen information, claiming that Liu "referred to using a tool and related software packages with names identical to proprietary internal engineering tools used at Apple." The next arguments by Apple claim that, after learning that he was the subject of its internal investigation, Liu directed a coworker at OpenAI to "restore" any Apple-issued devices, which Apple claimed was a way to erase forensic evidence that could be used against him. This is the latest salvo in a trade secret lawsuit Apple brought against OpenAI earlier this year.

Apple today submitted new evidence in its lawsuit against OpenAI, with the hope that the new information will persuade the judge to grant an expedited discovery process. Apple filed a theft of trade secrets lawsuit against OpenAI employees Chang Liu and Tang Tan in July, accusing them of using multiple methods to steal data from Apple.

Apple has filed a new document in its ongoing lawsuit against OpenAI as it continues to push for expedited discovery. In today’s filing, Apple says that it has new “shocking evidence” based on early forensic inspection of a laptop used by former engineer Chang Liu.

Liu kept an Apple-issued MacBook after he left for OpenAI, and Apple got it back after the lawsuit was filed. Apple now says forensic analysis of the laptop has uncovered more evidence of Liu’s use of Apple information and his attempts to hide what he’d done.

From the lawsuit: Mr. Liu not only downloaded a confidential Apple circuit schematic but also used it in his work at OpenAI; Far from his unauthorized access to Apple’s third-party cloud storage being unknown to him, Mr.

Liu and others at OpenAI were well-aware of that access; Mr. Liu, upon learning of Apple’s internal investigation of him, sent instructions for destroying evidence to an OpenAI colleague who confirmed she would comply; and Mr.

Liu used a tool in his work at OpenAI that has the same name as an internal Apple engineering application used for Apple development work. Liu downloaded the circuit schematic from Apple in March, two months after he left the company.

Liu used the schematic to run a simulation using electrical engineering tool LTspice, and then messaged people telling them he ran the simulation for power conversion development work. Liu described how he trained an AI agent to run LTspice.

According to the filing, he said he was "[f]eeling AI all day long," and that "[i]n the past hour," his AI "agent learned how to run LTspice, look at result, tune compensation parameter." "I try to make a behavior buck," he wrote. "With voltage outer and current inner.

It still took me a day.. Including learning fresh." "Oh man!

Why do they even need you then?" the person Liu was talking to reportedly replied. Liu used the Apple schematic on a Mac mini that later synced to the MacBook he took from Apple, which is why Apple knows about it.
