Apple Sues OpenAI: From Honeymoon to Full Confrontation, Battle for "Trade Secrets" Over AI Devices

OpenAI, a representative of generative AI, and Apple, one of the world's largest consumer device manufacturers, are set to face off in court.

In July 2026, Apple filed a lawsuit against OpenAI and several former Apple employees working there, accusing them of illegally acquiring and using trade secrets and confidential information, in the U.S. District Court for the Northern District of California.

According to Apple, the issue is not a simple case of information leakage where a departing employee took materials personally. There is suspicion that OpenAI systematically gathered information by leveraging relationships with Apple employees, job candidates, and even business partners and component supply networks to enter the consumer hardware business.

On the other hand, OpenAI denies the allegations, stating that it is not interested in other companies' trade secrets and is focused on independently developing innovative technologies that empower people.

The claims disclosed so far are based solely on Apple's complaint. The court has not determined the facts, nor has the legal responsibility of OpenAI and the former employees been established.

Nevertheless, the impact of this lawsuit on the technology industry is significant.

This is because the dispute is not only about past information leaks. Behind the conflict between Apple and OpenAI lies a competition over a massive market: who will hold the "main device of the AI era" that people will use after smartphones.

Apple's Allegation of "Systematic Information Acquisition" in the Complaint

It is reported that the complaint Apple submitted extends to 41 pages.

In it, Apple claims that the acquisition of confidential information by OpenAI was not an accidental act by some employees but occurred at multiple levels, from technical staff to executives and business partners.

The lawsuit targets not only OpenAI itself but also OpenAI Foundation, the commercial division OpenAI Group PBC, io Products related to consumer device development, and former Apple employees currently working at OpenAI.

One of the individuals named is Tan Tan, who leads OpenAI's hardware division.

Tan is known for his long tenure at Apple, deeply involved in the design of products like the iPhone and Apple Watch. He left Apple after about 24 years and joined a hardware business involving former Apple Chief Design Officer Jony Ive.

Another individual is Chan Liu, who was reportedly involved in electrical systems development at Apple.

Apple alleges that Liu exploited authentication flaws in the internal system to access highly confidential hardware-related files even after leaving the company. According to reports, the complaint states that he did not immediately return the company-issued laptop and downloaded multiple confidential documents.

However, these are Apple's claims, and in the upcoming trial, the focus will be on what files were actually accessed, whether the information was passed to OpenAI, and whether OpenAI directed or was aware of the acquisition or use.

Suspicion of Bringing Apple Components to Job Interviews

A particularly notable aspect of this lawsuit is Apple's claim regarding OpenAI's hiring practices.

According to Apple, OpenAI allegedly not only asked candidates to explain the technologies and unreleased products they were responsible for during job interviews but also encouraged them to bring physical Apple components.

The complaint reportedly includes an instance where a job candidate reacted in a way suggesting they did not think they could take items outside the company.

Generally, in technical job interviews, questions are asked about past work, problem-solving methods, and design philosophies. However, bringing confidential information, unpublished components, blueprints, or manufacturing data from a previous job could significantly exceed the bounds of normal hiring practices.

If Apple's claims are true, the issue goes beyond a simple breach of confidentiality by a job changer. It raises the question of whether the hiring process was used as a means to gather information from a competitor.

It is also crucial to determine whether OpenAI as an organization approved such actions or if they were the unilateral actions of certain individuals.

Component Manufacturers and Manufacturing Partners Also in Focus

Apple's competitiveness is not solely based on product appearance and software.

Choosing materials, selecting factories, using specific processing methods, and producing millions of devices with consistent quality—this integration of design, manufacturing, and procurement is one of Apple's strengths.

Particularly, technologies like casing processing, surface treatment, component miniaturization, thermal management, battery placement, sensor implementation, and yield improvement are not easily replicated by merely observing the product.

In the lawsuit, Apple claims that OpenAI attempted to obtain information about secret manufacturing techniques and supply networks through relationships with Apple's suppliers and business partners.

It is also reported that some business partners may have been misled into believing that OpenAI had Apple's permission.

If manufacturing techniques intended for Apple are used in other companies' products, the issue extends beyond individual blueprints. The criteria for selecting components, processing conditions, inspection methods, mass production issues, and their solutions—all accumulated practical knowledge over the years—becomes a competitive asset.

Apple's strong criticism of OpenAI's actions in this lawsuit likely stems from a wariness of having such manufacturing know-how utilized by new competitors.

Why the Two Formerly Cooperative Companies Are Now in Conflict

Apple and OpenAI were not adversaries from the start.

In 2024, the two companies announced a cooperative relationship to integrate ChatGPT into Apple products. Apple users could utilize ChatGPT's functions for specific tasks like text creation and image understanding.

At that time, the structure was such that Apple provided devices and OS like iPhones and Macs, while OpenAI provided advanced generative AI models. The relationship seemed more complementary than competitive.

However, the situation changed as OpenAI began to seriously develop its own consumer devices, moving beyond software.

OpenAI strengthened its collaboration with a hardware company involving renowned designer Jony Ive and eventually incorporated the related business under its umbrella. While details of the devices being developed are limited, there is anticipation for a new device centered around AI, differing from screen-centric smartphones.

If OpenAI's devices utilize voice, cameras, environmental recognition, and personal data to perform various tasks on behalf of users, it could create a different user experience from the current smartphone operation of individual apps.

In that case, the central role of connecting users to digital services might shift from the iPhone OS to AI assistants.

For Apple, OpenAI has become not only a partner supplementing AI functions but also a competitor that could potentially usurp the role of the iPhone itself.

What Apple Aims to Protect Is the Leadership of the "Next Device"

In this lawsuit, Apple aims to protect not only the secrets of products developed in the past.

For years, the company has built a strong business foundation by integrally managing devices, OS, semiconductors, services, and sales networks. Users purchase Apple devices, use Apple's OS, and utilize Apple's app distribution, payment, cloud, and content services.

However, as AI agents understand user instructions and process tasks across multiple services, the presence of OS and apps may diminish.

In a world where users ask AI to "book a flight," "share plans with family," or "compile necessary materials," and AI handles everything behind the scenes, what matters more is which AI is used as the interface rather than which app is opened.

If OpenAI provides devices optimized for its AI, it can directly hold the point of contact with users.

This poses a potential threat to the platform dominance Apple has maintained for years.

This lawsuit is not only a legal case over the illegal acquisition of trade secrets but also an industrial competition over who will dominate the next generation of computing environments.

What Apple Must Prove in the Lawsuit

In lawsuits over trade secrets, simply claiming "information was taken" does not guarantee a win.

Apple must first demonstrate that the information in question was not generally known and had economic value due to its secrecy.

Furthermore, it is important to show that reasonable measures were taken to protect that information, such as access restrictions, confidentiality designations, non-disclosure agreements, and device management.

Additionally, Apple must prove that the former employees illegally acquired the information and that OpenAI used it knowingly.

Particularly, to hold OpenAI itself accountable, the connection between individual former employees' actions and the company's instructions or benefits will be a focal point.

Whether Apple can present concrete evidence such as emails, access logs, download histories, internal chats, interview records, and communications with business partners will be crucial.

Conversely, OpenAI may attempt to demonstrate that it independently developed the disputed technology, prohibited the receipt of Apple's information, and took appropriate action when suspicious information was brought in.

Moreover, it is generally permissible for engineers to use general experience and skills after changing jobs. The distinction between Apple's proprietary trade secrets and the general knowledge acquired by individual engineers could also become a point of contention.

OpenAI's Rebuttal and Future Actions

OpenAI explained to the media that it is not interested in other companies' trade secrets and is focused on building innovative technologies that empower people.

This brief statement effectively denies Apple's claims.

Once OpenAI submits a formal answer to the court, more detailed rebuttals are expected to be revealed.

One possible rebuttal is that Apple's complaint unjustly links the personal actions of former employees with OpenAI's organizational conduct.

Additionally, OpenAI might argue that some of the information Apple claims as trade secrets is vague, already known in the industry, or independently obtained or developed by OpenAI.

If OpenAI can prove that its hardware plans do not rely on Apple's technology, it can mitigate the business impact of the lawsuit.

However, if internal communications reveal that OpenAI actively sought Apple's confidential information, it poses a significant risk to OpenAI.

This is because, beyond damages, there is a possibility of being ordered to cease product development using specific information or to make design changes.

Potential Impact on AI Device Launch Plans

The biggest concern for OpenAI is that the lawsuit could affect the development and launch of its hardware products.

For consumer devices, the timing of announcements and market launches is crucial. Falling behind competitors could disadvantage OpenAI in building relationships with users, developers, and component manufacturers.

If Apple requests the court to prohibit the use of disputed trade secrets or to halt product development and it is granted, OpenAI may be forced to review its designs.

Even if a halt is not ordered, significant time and costs may be required for internal investigations and evidence disclosure to confirm which technologies originated from Apple's information.

Furthermore, suppliers and manufacturing contractors may become cautious about dealing with OpenAI due to legal risks.

To mass-produce new devices, OpenAI needs not only design capabilities but also to establish systems for component procurement, manufacturing, quality control, logistics, repair, and post-sales support.

For OpenAI, which has limited hardware experience, the lawsuit with Apple adds complexity to an already challenging business.

Impact on IPO and Fundraising

The original article also touches on the possibility that this lawsuit could complicate OpenAI's future plans for a public offering.

The lawsuit does not immediately make an IPO impossible. However, large-scale legal disputes become risk factors when investors evaluate a company's value.

This is because they must consider the possibility of significant damages being awarded in the lawsuit, potential delays in product launches, and potential issues with corporate governance and compliance systems.

In particular, Apple's claims are that the actions occurred across multiple levels of the company, not just as isolated incidents in OpenAI's hardware division.

If proven, investors will scrutinize not only the technical capabilities but also the hiring methods, information management, legal reviews, and oversight systems of the management team.

Conversely, if Apple's claims are dismissed, OpenAI can demonstrate that its hardware development is an independent and legitimate endeavor.

Therefore, this trial could influence OpenAI's credibility and future strategy more than the amount of damages.

Notable Reactions on Social Media

Once the lawsuit was reported, related posts and news shares quickly followed on platforms like X and Reddit.

However, the following are trends observed from some public posts and threads and do not represent the opinion of society as a whole. As these are reactions immediately following the incident, evaluations may change as new evidence or rebuttals emerge.

1. Voices Taking Apple's Claims Seriously, Saying "If True, It's Serious"

The most straightforward reaction is that if the actions described in Apple's complaint are true, it goes beyond ordinary talent acquisition competition.

Particularly notable were posts expressing surprise at the allegations of accessing internal systems after resignation, downloading confidential files, and bringing company components to job interviews.

While it is not uncommon for engineers to move to competing companies, taking materials or components from a previous job is a different issue.

Some posts also expressed concern that the rapid growth of the AI industry might mean that legal and compliance measures are not keeping pace with business expansion.

2. Voices Questioning Apple's Information Management

Not all reactions are fully supportive of Apple.

Regarding the claim that former employees could access the internal network after resignation, questions arose about why accounts and devices were not properly deactivated at a company like Apple.

If there were authentication flaws, some users believe that there was room for improvement in Apple's management of retirees and security audits, separate from the responsibility of the individuals who committed unauthorized access.

The responsibility to protect trade secrets lies not only with employees
