Apple Sues OpenAI Over Alleged Trade Secret Theft

Apple sued OpenAI on July 10, 2026, accusing the company and two former Apple employees of misappropriating confidential hardware designs, manufacturing methods, supplier information, and other trade secrets related to future consumer devices.

OpenAI denied any interest in competitors’ trade secrets, and no court has ruled that any defendant engaged in wrongdoing.

The lawsuit places employee departures, recruitment practices, access controls, and trade secret protection under renewed scrutiny as AI companies compete to build next-generation hardware.

This article explains Apple’s allegations, the events that led to the lawsuit, the claims against former Apple employees and OpenAI’s hiring practices, the legal standards under the Defend Trade Secrets Act, the damages Apple seeks, and the compliance lessons the case presents.

It examines insider-risk controls, employee offboarding, recruitment safeguards, supplier oversight, data protection, the potential impact on OpenAI’s hardware ambitions and IPO plans, and the legal questions that remain unresolved as the case moves through federal court.

What Does Apple Allege OpenAI Took?

Apple alleges that OpenAI obtained information covering unreleased products, hardware engineering, component design, manufacturing processes, product roadmaps and supplier relationships. Apple says the information had economic value because it was secret and could reduce the time and investment required for a competitor to develop consumer hardware.

The complaint alleges that OpenAI obtained information through several routes:

• Former employees allegedly retained Apple documents and equipment.
• OpenAI personnel allegedly questioned job candidates about confidential Apple projects.
• Candidates were allegedly asked to bring physical Apple components to interviews.
• Departing employees allegedly received guidance on avoiding Apple’s exit-security procedures.
• OpenAI, through io, allegedly had a trusted Apple partner perform a specific trade secret metal-finishing technique after misleading the partner into believing Apple had authorized the work.

Apple says the affected information included technical presentations, engineering records, unreleased product details, component-testing methods and manufacturing information.

The Verge and other outlets quote the complaint as alleging that Liu downloaded “dozens of Apple’s confidential hardware-related files.” JURIST separately reported that the downloaded material exceeded 1,000 pages. The figures measure different things: one describes the number of files, while the other describes the combined page volume of the material.

Apple has not assigned a public dollar value to the allegedly taken information. The company says it invested decades of research and substantial financial resources in the hardware, manufacturing and supply-chain systems covered by the complaint.

How Did Apple’s Trade Secret Dispute With OpenAI Develop?

Apple says the dispute developed after Chang Liu left the company for OpenAI in January 2026. Tech industry coverage describes Liu as a senior systems electrical engineer who spent 8 years at Apple. Apple alleges that he did not complete normal exit procedures, failed to return at least one company computer and later accessed internal network storage after his employment ended.

Apple alleges that Liu used an authentication flaw and a current employee’s Apple computer to reach internal systems. The complaint says he downloaded dozens of confidential hardware-related files around February 2026, including information related to main logic board manufacturing and testing. Apple says the authentication problem has since been corrected.

Apple wrote to OpenAI in February 2026 to report its initial concerns and request a response. The complaint says OpenAI did not reply, leading Apple to continue its internal investigation before filing the lawsuit.

The dispute developed while the companies remained commercial partners. Apple and OpenAI signed an agreement in 2024 to integrate ChatGPT with Apple Intelligence. Apple states that the integration agreement is separate from the alleged trade secret conduct and is not challenged in this lawsuit.

What Does Apple Allege Against Tang Tan And OpenAI’s Hiring Team?

Apple alleges that Tang Tan used knowledge gained during 24 years at Apple to obtain confidential information from current employees interviewing for OpenAI jobs. Tan previously served as an Apple vice president of product design and now leads OpenAI’s hardware operations.

The complaint says Tan asked candidates to bring “actual parts” to interviews for demonstrations. The requested materials allegedly included batteries, logic boards, shields, prototypes and design information connected to unreleased Apple projects.

Apple claims OpenAI interviewers used internal Apple project codes to ask targeted questions about confidential programs. The company says this allowed former Apple insiders to recognize projects and request information that an outside interviewer would not know to ask for.

The complaint further alleges that Tan retained an Apple document marked “Need to Know” that described security procedures for departing employees. Apple says OpenAI personnel circulated the document to recruits and gave them advance notice of exit interviews, forensic checks and access-removal procedures.

OpenAI spokesperson Drew Pusateri said the company has no interest in other companies’ trade secrets and remains focused on developing its own technology. Tan and Liu had not publicly provided detailed responses to the allegations when the complaint was reported.

Which Defend Trade Secrets Act Claims Did Apple File?

Apple filed 4 claims under the federal Defend Trade Secrets Act and 2 breach-of-contract claims. The federal claims individually target Liu, Tan, OpenAI and io Products, while the contract claims allege that Liu and Tan violated intellectual property agreements signed during their Apple employment.

The Defend Trade Secrets Act protects financial, technical, scientific, engineering and business information when the owner has taken reasonable measures to keep it secret and the information receives economic value from remaining unknown. Misappropriation can include improper acquisition, disclosure or use of protected information.

Apple must prove that the claimed information qualifies as protected trade secrets. It must further show that one or more defendants acquired, disclosed or used the information through improper means.

The company cites confidentiality markings, restricted systems, intellectual property agreements, exit procedures and monitoring of company-owned devices as measures used to protect the information. OpenAI can challenge whether the information was secret, whether Apple’s safeguards were reasonable and whether the defendants used any protected information.

The lawsuit is a private civil action. No regulator has announced a separate enforcement proceeding based on the allegations in the public sources reviewed through July 14, 2026.

What Damages And Injunctions Is Apple Seeking From OpenAI?

Apple seeks preliminary and permanent injunctions that would prevent OpenAI and the other defendants from possessing, using or disclosing its alleged trade secrets. It requests the return of Apple information and property, preservation of electronic evidence, compensatory damages, unjust-enrichment damages, a reasonable royalty and attorneys’ fees.

Apple has not specified a damages amount. It says the final figure should account for lost competitive advantage, reduced trade secret value and any research or development costs that OpenAI allegedly avoided.

The Defend Trade Secrets Act permits a court to award damages for actual loss and unjust enrichment. A court may substitute a reasonable royalty when other damage calculations are unsuitable. Willful and malicious misappropriation can result in exemplary damages of up to 2 times the compensatory damages awarded.

The requested injunction could carry greater operational consequences than a monetary award. A court order could require OpenAI to isolate design work, review devices and repositories, return materials or demonstrate that its hardware development does not rely on Apple information. The court has not granted such relief.

Apple has requested a jury trial. The case remains at an early stage, and the defendants must receive an opportunity to respond before the court determines whether the allegations are supported.

What Compliance Failures Does The Apple v. OpenAI Lawsuit Put Under Scrutiny?

The Apple lawsuit places employee offboarding, access governance, recruitment controls, device recovery and third-party confidentiality under scrutiny. Because a departing engineer allegedly kept credentials and company hardware, the case reads as a study in insider threat risks and mitigation, where one unresolved account, retained computer or poorly controlled interview creates exposure across trade secrets, contracts and incident response.

Apple’s allegations point to several compliance risks.

1. Delayed Access Termination. Accounts, sessions, tokens and shared-storage permissions should be disabled when employment ends or when an employee enters a high-risk departure process.
2. Unreturned Company Devices. Organizations should maintain an asset inventory and confirm that laptops, phones, storage media, prototypes and authentication devices are returned.
3. Weak Recruitment Boundaries. Interviewers should be prohibited from requesting confidential documents, physical components, source code or details about unreleased projects from another company.
4. Poor Data-Loss Monitoring. In the window around a departure notice, unusual bulk downloads, screenshots and external file transfers are the clearest signals to watch when working to prevent data exfiltration, so security teams should flag personal-email activity and access to sensitive repositories.
5. Supplier Authorization Gaps. Vendors should confirm that a company has authority to request proprietary manufacturing work, component information or techniques originally developed for another customer.
6. Incomplete Evidence Preservation. Legal and security teams should issue litigation holds and preserve emails, messages, access logs, device images, metadata and directory records when suspected theft is reported.

Trade secret protection depends partly on whether the owner used reasonable secrecy measures. Policies that exist only on paper may provide weaker evidence than documented access restrictions, device controls, confidentiality training and enforced offboarding procedures.

How Could Apple’s Lawsuit Affect OpenAI’s Hardware Plans And IPO?

The lawsuit could affect OpenAI’s hardware program through legal costs, discovery demands, supplier uncertainty and possible restrictions on using disputed information. OpenAI announced the io Products acquisition in May 2025, but published reports value the transaction differently. AP, Axios and several technology outlets reported approximately $6.5 billion, while other reporting placed it at approximately $6.4 billion. The transaction is therefore best described as an acquisition valued at about $6.4 billion to $6.5 billion.

Apple alleges that OpenAI has hired more than 400 former Apple employees. Staff movement alone does not prove misappropriation. The number increases the importance of recruitment rules, information-separation procedures and records showing that new employees did not bring materials from prior employers.

OpenAI announced on June 8, 2026, that it had confidentially submitted a draft Form S-1 to the Securities and Exchange Commission. The company said it had not decided when to proceed with an initial public offering.

Regulation S-K Item 103 requires registration statements to describe material pending legal proceedings, including the parties, factual basis and relief sought. OpenAI and its advisers must determine whether the Apple dispute is material to its business, finances or planned hardware operation. That determination has not been made public.

What Remains Unresolved In Apple’s Lawsuit Against OpenAI?

The court must determine whether Apple has adequately defined its trade secrets, whether its controls were reasonable and whether the defendants obtained or used protected information through improper means. Discovery may examine OpenAI’s recruitment records, hardware repositories, internal messages, supplier communications and product-development history.

OpenAI has provided a brief denial but has not filed a detailed public answer addressing each allegation. The individual defendants have not publicly presented their full defenses.

The effect on the Apple and OpenAI commercial partnership remains unclear. Apple expressly excluded the ChatGPT integration agreement from the lawsuit, meaning the filing does not directly seek to end ChatGPT access through Apple Intelligence.

No court has ruled that OpenAI, Liu, Tan or io Products misappropriated Apple information. The complaint states Apple’s allegations, and the defendants remain entitled to challenge the facts, legal claims and requested remedies.
