Apple claims former employees stole proprietary files to aid OpenAI’s hardware business. The lawsuit involves over 400 staff departures to the AI startup.

Apple has filed new evidence in its ongoing trade secret lawsuit against OpenAI, alleging that a former senior system electrical engineer used a company-issued laptop to download confidential circuit schematics and proprietary engineering tools after joining the AI firm [1]. The legal escalation, which now encompasses allegations involving 11 former Apple employees, underscores a deepening conflict over intellectual property and talent poaching between the two tech giants [1].

## The forensic evidence
Apple’s latest filing centers on Chang Liu, a former senior system electrical engineer who the company claims accessed Apple’s third-party cloud storage to download dozens of confidential files [1]. Forensic analysis of a MacBook used by Liu allegedly revealed that he utilized software packages with names identical to internal Apple engineering tools to run simulations for his work at OpenAI [1]. Furthermore, Apple alleges that after becoming aware of an internal investigation, Liu instructed a coworker to "restore" Apple-issued devices, an act the company characterizes as an attempt to destroy forensic evidence [1].

OpenAI has rejected these claims as "meritless" and has requested that a federal judge dismiss the case [2]. In a 28-page response, OpenAI’s legal team argued that Apple’s accusations are a pretextual attempt to compensate for its own failures in AI integration and talent retention [2]. OpenAI contends that the alleged file access was limited to helping former colleagues locate information after Liu's departure in January, and that other interactions cited by Apple constitute "routine recruitment and hardware-development activity" [2]. The startup also pointed to Apple’s own workplace policies, noting that the company allows employees to access work documents via personal iCloud accounts, which OpenAI claims blurs the line between private and corporate data [3].

## A broader talent war
The litigation highlights the intensifying competition for specialized engineering talent in Silicon Valley. Apple, which has been perceived as a late entrant to the generative AI market compared to competitors, has seen more than 400 of its former employees move to OpenAI [2]. This friction has been exacerbated by OpenAI’s recent expansion into hardware, including its acquisition of IO, a company founded by former Apple executive Jony Ive and former Apple employee Tang Tan [2]. While Apple and OpenAI entered a partnership in June 2024 to integrate ChatGPT into Siri, the relationship has soured as OpenAI continues to build out its own hardware capabilities [2].

## What to watch
*   **Court discovery rulings:** Monitor whether a federal judge grants Apple’s request for expedited discovery, which would force OpenAI to turn over more internal documents [1].
*   **Evidence of hardware impact:** Watch for further filings that attempt to link specific stolen schematics to tangible products or features currently under development at OpenAI [3].
*   **Talent retention metrics:** Observe if the legal pressure impacts the rate of high-level engineering departures from Apple to AI-focused startups [2].

The core of the dispute remains whether Apple can prove that specific, actionable trade secrets were used to gain a competitive advantage in hardware, or if the lawsuit is a strategic response to the industry-wide migration of talent toward AI-native firms. With both companies accusing the other of bad faith, the resolution of this case may set a new precedent for how tech giants protect intellectual property in the era of rapid AI development.
