Bloomberg Reveals Apple's Lawsuit Against OpenAI Insider Details

Bloomberg has reported new details in the lawsuit filed by Apple against OpenAI. The case centers on former Apple engineer Chang Liu and the way he allegedly retained access to internal systems after leaving the company.

The complaint describes how Liu kept a company MacBook that was not returned. He later used an overlooked software flaw to reach Apple network storage. When the access worked, he sent a short message to a coworker that read roughly "haha, I can still reach the storage."

That exchange is now cited by Apple as evidence of coordinated access to proprietary files. The documents claim the coworker helped retrieve additional information. Apple alleges the materials described internal product processes that OpenAI later tried to replicate.

The filing states that more than 400 Apple employees have moved to OpenAI in recent years. One of them, Tang Tan, now serves as OpenAI chief hardware officer. Apple claims this movement of staff increased the value of any information that left with Liu.

According to the complaint, Apple first attempted to resolve the dispute quietly in February. OpenAI did not respond to that outreach. The company then filed the lawsuit in federal court.

The suit accuses OpenAI of building elements of its hardware and product development structure on information taken from Apple. Apple says the copied elements include specific review cycles and cross-team coordination methods used on the iPhone line.

OpenAI has not issued a detailed public response to the latest filing. In earlier statements the company has maintained that it hires talent openly and builds its own systems from public research and its own data.

Industry analysts note that employee departures between large technology firms are common. What stands out in this case is the specific technical access described and the internal message Apple chose to highlight in court papers.

The core tension is between the normal flow of talent and the line Apple draws around proprietary development processes. The "haha" message is presented as the moment casual access turned into documented sharing.

Apple's filing lists several categories of documents it says were taken. These include unreleased hardware specifications, internal tooling guidelines, and meeting notes from product review sessions. No customer data is mentioned.

The complaint does not provide independent verification that OpenAI actually used the materials. Instead it argues the timing and similarity of certain internal practices raise the inference of use.

OpenAI has previously described its hardware efforts as independent projects led by its own teams. The company has not released detailed public roadmaps that would allow direct comparison with the Apple documents cited in the suit.

Observers say the case may test how courts treat residual access that was never explicitly revoked. Many companies assume accounts are closed at termination, yet older storage systems sometimes retain cached credentials.

The suit also names the colleague who received the message. Apple claims that person forwarded additional links and credentials. Both individuals are listed as former employees and are not currently defendants.

Apple is asking the court for an injunction and damages. The company has not disclosed a specific dollar amount in public filings.

The case arrives at a time when hardware ambitions at OpenAI are expanding. The company has stated plans for custom inference systems and consumer devices. Any finding that early designs drew on Apple processes could affect those plans.

Legal experts note that trade secret cases often settle before trial. Apple tried that route once already. If talks resume, the public record may stay limited to the initial complaint.

For now the narrative rests on the short internal exchange and the unreturned laptop. Both details are drawn directly from the court filing.

The next steps are likely a motion to dismiss or an answer from OpenAI followed by possible discovery. Any technical exhibits filed under seal could limit further public reporting.

Readers following AI hardware should watch for OpenAI product announcements that reference new internal review processes. Parallel announcements from Apple about tightened access controls would also be relevant signals.

The episode illustrates how small oversights in offboarding can become central evidence in later litigation.

Further coverage from established outlets will clarify whether additional technical details surface in unsealed exhibits. The current record already shows how quickly a single retained credential can expand into a broader dispute.
