Apple has filed a federal lawsuit against OpenAI and several individuals, alleging the AI company illegally obtained trade secrets and used them to advance its own hardware ambitions. The complaint, lodged in U.S. District Court in San Jose, California, names OpenAI, a company called io Products, and two ex-Apple employees—Tang Yew Tan and Chang Liu—as defendants. Apple is seeking financial damages and a court order that would block all defendants from possessing or using the disputed trade secrets. The case, first reported by Bloomberg Law, escalates a hidden tension between two tech giants racing to build next-generation computing devices.

The Allegations: What Apple Claims Was Stolen

The lawsuit details a coordinated effort to divert Apple’s confidential hardware technologies to OpenAI. According to the filing, Tan and Liu—both former Apple engineers—allegedly transferred proprietary information to io Products, a firm they joined after leaving Apple. That company subsequently shared those trade secrets with OpenAI, which is now using them to design custom chips, sensors, or other hardware components for its AI products. Apple’s legal team identifies a range of protected trade secrets, including:

  • Custom silicon designs and chip architectures developed over years of R&D.
  • Manufacturing processes and supply-chain optimizations unique to Apple’s hardware ecosystem.
  • Sensor integration techniques that combine optics, motion tracking, and power management.
  • Proprietary testing and validation frameworks used to ensure hardware reliability at scale.

The complaint stops short of specifying exactly which OpenAI products may have derived from these secrets, but it notes that the AI company’s recent pivot toward hardware—such as custom ASICs for training and inference—raises “substantial concerns” about the origins of its technical knowledge.

Who Is io Products and What’s Its Role?

io Products emerges as a key intermediary in this dispute. Public records show it was founded shortly after Tan and Liu departed Apple. The company has kept a low profile, but its incorporation papers list “integrated hardware and AI systems” as its primary business. Apple alleges that io Products served as a vehicle to collect and repackage Apple’s trade secrets before passing them to OpenAI, possibly to obscure the paper trail. OpenAI’s involvement, according to the complaint, was not passive; the AI firm actively recruited the two engineers and “knew or should have known” that their knowledge was tainted by confidentiality obligations.

This is not the first time a technology startup has been accused of acting as a middleman for stolen intellectual property. In 2022, a similar case saw Tesla sue Rivian over allegedly poaching employees to gain battery secrets. Such suits rest on the legal doctrine of “inevitable disclosure,” which holds that a former employee’s new role may inherently lead to the use of their previous employer’s trade secrets, even without direct evidence of theft.

What the Lawsuit Means for Apple, OpenAI, and the Tech Industry

For Apple, this case is about protecting its most precious asset: hardware design know-how. The company invests billions annually in custom silicon, like the M-series and A-series chips, and has spent decades optimizing the interplay between hardware and software. Allowing a rival to shortcut that process could erode a competitive moat that underpins the iPhone, Mac, and Vision Pro.

For OpenAI, the suit poses an existential risk to its hardware roadmap. CEO Sam Altman has publicly stated that the company needs specialized chips to reduce Cloud AI costs and enable more capable models. Reports suggest OpenAI is developing its own “AI accelerator” chips, with possible manufacturing partnerships at TSMC. An injunction could freeze that project, force OpenAI to license technology from a clean source, or even push it to settle by paying significant royalties to Apple.

For the broader tech industry, the litigation sends a chilling signal about the fluid movement of talent between Big Tech and AI startups. Many AI companies, including OpenAI, have hired aggressively from Apple’s hardware divisions. If Apple wins, it could set a precedent that makes it riskier for engineers to jump ship, especially when their new role closely mirrors their old one. That could slow innovation by locking knowledge within legacy firms.

How We Got Here: A Pattern of Trade Secret Crackdowns

Apple’s hardball legal strategy isn’t new. The company has a long history of suing former employees who allegedly took secrets to competitors. In 2018, it won a high-profile case against a chip designer who left for a Chinese startup. More recently, in 2023, it settled with Rivos, an AI chip startup, after bringing similar trade secret claims. Those cases underscore Apple’s willingness to litigate rather than tolerate what it sees as intellectual property theft.

This latest suit, however, is remarkable because it directly names OpenAI—a company that, until now, has largely avoided public legal battles over core technology. OpenAI has positioned itself as a research-first organization, but its commercial ambitions increasingly rely on hardware differentiation. The fact that Apple is targeting not just individuals but the AI giant itself suggests that Apple believes OpenAI is a willing participant in the misappropriation.

Legal experts say Apple’s decision to seek an injunction—rather than just monetary damages—shows it intends to disrupt OpenAI’s hardware development immediately. “If Apple can show that the trade secrets are being used in current OpenAI prototypes, they might get a preliminary injunction in a matter of months,” said Sarah Burstein, a trade secret law professor who reviewed the complaint for our publication. “That could stop a product launch dead in its tracks.”

What Windows Users Need to Know

While the lawsuit is between two companies that compete with Microsoft, it has direct implications for the Windows ecosystem. Microsoft is OpenAI’s largest investor and deeply integrates its models into Windows, through Copilot features and Azure AI. If OpenAI’s hardware plans are disrupted, Microsoft may need to rely more heavily on third-party hardware partners like NVIDIA for the compute power needed by future AI models. That could increase costs or delay the rollout of more advanced Windows AI features.

Furthermore, any slowdown in OpenAI’s ability to reduce inference costs could mean that premium AI features stay behind a paywall longer. Windows users who rely on free Copilot tiers might see slower improvements or fewer features if OpenAI’s capacity is constrained. Conversely, if Apple succeeds, it might accelerate its own AI hardware development, potentially widening the gap between Apple’s M-series chips and the Intel/AMD processors common in Windows PCs. Competition could push all sides to innovate faster, but legal gridlock usually does the opposite.

Actionable Steps for IT Professionals and Developers

If you work in or manage a technology team, this case offers concrete lessons:

  • Review your onboarding and exit procedures. Trade secrets often walk out the door when employees leave. Ensure your HR and legal teams tighten nondisclosure agreements and exit interviews, especially for roles involving hardware or AI design.
  • Audit your supply chain. If you license technology from startups or rely on third-party hardware IP, verify that their innovations are legitimately developed and not derived from a competitor’s secrets. A lawsuit could disrupt your own product pipeline.
  • Stay informed on the legal landscape. The outcome of this case could influence how courts view trade secret protection in the AI era. If you develop AI models or hardware, consult with IP counsel to understand your exposure.
  • Diversify your AI hardware bets. If your business depends on OpenAI’s models, consider backup plans that use alternative hardware providers—like AMD, Intel, or even run-on-device AI through Windows PCs with NPUs. That way, a potential injunction against OpenAI’s custom chips won’t leave you stranded.

For consumers, there’s not much direct action to take, but it’s wise to be aware that behind-the-scenes IP disputes can delay product updates. If you rely on a specific AI tool or device that might incorporate contested technology, keep an eye on the manufacturer’s legal disclosures.

Outlook: What to Watch Next

The lawsuit is in its earliest stages. Apple has 90 days to serve the defendants, and then OpenAI will have 21 days to respond. Expect a series of motions: OpenAI may move to dismiss for lack of evidence, while Apple will push for a preliminary injunction. Key hearings could happen in the first half of 2025. For Windows users and the industry at large, the real question is whether this sparks a broader wave of litigation that forces the AI and hardware communities to re-examine the ethics and legality of employee mobility. The outcome could reshape how the next generation of AI hardware is built—and who gets to build it.
