On July 10, 2026, Apple filed a 41-page trade secret complaint in the Northern District of California against OpenAI and io Products — the hardware design firm OpenAI acquired in 2025 for $6.4 billion that Jony Ive co-founded after leaving Apple. The complaint names OpenAI’s Chief Hardware Officer Tang Tan and a former Apple engineer Chang Liu, and alleges that OpenAI ran a systematic program to extract Apple’s unreleased hardware secrets through its recruiting pipeline. Part of our Builder’s Log.

The Core Allegation

Apple’s complaint accuses OpenAI of intellectual property theft “at every level, from members of its Technical Staff to its Chief Hardware Officer.” The company calls OpenAI’s hardware ambitions built on a “foundation rotten to its core” by the alleged misappropriation.

The complaint is not about software or LLMs. It is specifically about consumer hardware product secrets — the kind of information that would help a new entrant understand how to design, manufacture, and source components for a competitive AI device.

The Named Individuals

Tang Tan — OpenAI Chief Hardware Officer

Tan spent 24 years at Apple as VP of product design for iPhone and Apple Watch before joining OpenAI following the io Products acquisition. Apple’s complaint alleges that Tan:

  • Used confidential Apple project codenames during external recruiting calls
  • Directed job candidates still employed by Apple to bring “actual parts” from Apple to their OpenAI interviews for “show and tell”
  • Coached departing Apple employees on how to evade Apple’s internal security procedures when downloading files

Apple argues that the “show and tell” recruiting practice was not incidental but deliberately designed to extract physical hardware samples and accompanying knowledge before candidates officially left.

Chang Liu — OpenAI Senior Systems Electrical Engineer

Liu spent eight years at Apple as a senior systems electrical engineer before moving to OpenAI in 2026. Apple’s complaint alleges that Liu:

  • Failed to return an Apple-issued laptop after departing
  • Downloaded dozens of confidential Apple technical documents on that computer before leaving — including unreleased product specifications and engineering presentations
  • Shared Apple confidential information with other Apple employees who were interviewing at OpenAI
  • Instructed a current Apple employee on how to bypass Apple’s security protocols to retrieve additional materials

What Apple Says Was Stolen

The complaint identifies several categories of allegedly misappropriated information:

  • Unreleased hardware product specifications
  • Engineering presentations for unannounced technologies
  • Component, vendor, and supplier relationship data (contact information for Apple’s supply chain)
  • A proprietary metal finishing technique
  • Confidential Apple project codenames
  • Apple’s internal terminology and organizational language

The vendor and supplier list may be the most commercially sensitive item here. Building an AI consumer device requires negotiating with component manufacturers, display suppliers, RF hardware vendors, and battery suppliers — most of whom have existing Apple relationships. If OpenAI had access to Apple’s supplier contacts and pricing arrangements, that is a meaningful head start.

The io Products Connection

OpenAI acquired io Products in May 2025 for $6.4 billion. io Products was co-founded by Jony Ive — Apple’s former Chief Design Officer, who designed the iMac G3, iPod, iPhone, and Apple Watch. Ive is not named as a defendant in this complaint.

OpenAI has described the io Products acquisition as the foundation of its consumer hardware effort — widely reported to be an AI-first smartphone that would replace apps with AI agents as the primary interface. Apple’s complaint directly targets that product direction, arguing that the hardware division now being built at OpenAI rests on illegally obtained knowledge of how Apple builds its own devices.

Apple’s filing puts a legal cloud over the io Products roadmap. If a court issues the injunctive relief Apple is requesting — barring OpenAI from using or disclosing the alleged trade secrets — OpenAI’s hardware team would need to demonstrate that each component of its design process is free of tainted information. That is a difficult affirmative showing in trade secret litigation.

Relief Apple Is Seeking

Apple has asked the court to:

  • Bar OpenAI from using or disclosing Apple’s trade secrets in any form
  • Compel the return of all confidential Apple materials, including the unreturned laptop
  • Preserve all evidence relevant to the allegations

Apple is also seeking compensatory and punitive damages, though the specific dollar figures are not disclosed in the public complaint.

OpenAI denied the allegations in a statement: “we have no interest in other companies’ trade secrets.”

The Partnership That Curdled

This lawsuit is notable not just for its allegations but for its context. In 2024, Apple and OpenAI signed a landmark partnership: ChatGPT became integrated into iOS 18 and macOS Sequoia through Siri, making OpenAI the first third-party AI provider embedded at the OS level on an Apple device.

At the time, the deal was described as mutually beneficial — Apple got a capable AI model without building it, OpenAI got access to Apple’s hardware install base. Apple-specific instructions, privacy protections, and Siri routing made it the deepest third-party AI integration Apple had ever permitted.

Relations between the two companies began to chill in early 2026 when OpenAI announced its hardware ambitions publicly and the io Products acquisition became common knowledge. An AI device designed to bypass the App Store and reduce iPhone dependency would directly undercut Apple’s platform control. The trade secret complaint is the legal escalation of what was already a commercial and strategic confrontation.

What This Means for the iOS-ChatGPT Integration

The 2024 ChatGPT-in-iOS integration agreement is a separate contract from this lawsuit. Apple has not announced plans to terminate the arrangement, and there is no injunction yet.

However:

The integration sits in a precarious position. If litigation intensifies — particularly if Apple seeks discovery into OpenAI’s communications about its hardware plans — the relationship between the two companies will become adversarial in ways that make maintaining an OS-level partnership awkward for both sides.

Apps that depend on the ChatGPT-Siri integration have a new risk factor to track. The iOS-ChatGPT flow is not a standard API call — it runs through Apple’s specific Siri routing architecture and Apple’s data privacy representations to users. If that integration breaks for legal or commercial reasons, there is no direct fallback.

Apple’s own model strategy is relevant here. Apple announced its Foundation Models framework at WWDC 2026, with third-generation on-device models and Private Cloud Compute for server-side inference. Apple’s long-term interest is to reduce reliance on external AI providers. This lawsuit accelerates that calculus.

What Builders Should Watch

The injunction hearing timeline. Apple is seeking preliminary relief. If Apple moves for a temporary restraining order or preliminary injunction, there will be an emergency hearing. A TRO could immediately constrain what OpenAI’s hardware team is allowed to do — even before a full trial. Watch for filings over the next 30-60 days.

OpenAI’s hardware launch timeline. OpenAI had indicated its AI device could launch in 2026-2027. This lawsuit creates legal risk that could delay a launch if key design decisions become entangled in discovery.

The Apple-ChatGPT API traffic. If Apple and OpenAI renegotiate or terminate the iOS integration, there will be a disclosure or App Store policy change that becomes visible. Monitor Apple’s iOS 27 developer notes and ChatGPT iOS release notes for any changes to the Siri routing architecture.

Talent practices generally. The Tang Tan “show and tell” allegation — asking candidates to physically bring proprietary hardware to interviews — is unusually specific. It suggests Apple has forensic evidence (device logs, communications records) supporting the claim. For engineers recruiting in AI hardware, this case will sharpen awareness of what behavior crosses into trade secret misappropriation territory.

Bottom Line

This is not a routine IP spat. Apple is alleging that a systematic, leadership-directed program extracted the specific hardware knowledge needed to build a competing device — and that the knowledge now sits inside the company they acquired from Jony Ive for $6.4 billion. Whether the allegations hold up in court, the lawsuit puts OpenAI’s hardware ambitions on legal hold and puts the iOS-ChatGPT partnership in a new adversarial frame. For builders whose products depend on either platform, it is worth tracking the injunction proceedings closely.
