The legal dispute intensifies between Apple and OpenAI
Apple initiated legal proceedings against OpenAI last month, accusing it of acquiring confidential trade secrets from former Apple employees to further its own hardware development. The suit specifically claims these individuals accessed Apple’s private information before and after their time at the company. OpenAI has now taken a more active stance, responding with a detailed blog post addressing the allegations.
Following Apple’s lawsuit, OpenAI issued a brief denial, stating no interest in trade secrets from other companies. For three weeks, it remained largely quiet. On August 4, OpenAI published an extensive blog post titled “Apple is getting this wrong,” offering a full explanation of its side and countering Apple’s claims with specifics and supporting evidence. Apple has now filed a motion seeking a preliminary injunction against OpenAI and two former Apple employees, Chang Liu and Tang Tan, to prevent them from accessing, using, or disclosing Apple’s alleged confidential information.
OpenAI's Response and Criticism
In the blog post, OpenAI criticized Apple for its approach, calling the legal action “careless, aggressive, and oddly personal.” It argued that Apple failed to properly communicate its concerns and missed opportunities to resolve the matter without legal escalation. The blog highlighted the company’s belief that Apple did not make a genuine effort to resolve the issue before pursuing the lawsuit.
Communication and evidence challenges
Communication and Evidence Challenges
OpenAI pointed out that Apple’s legal team initially failed to contact the correct person, due to confusion over two similar Asian last names. The AI company also corrected Apple’s claim that a meeting occurred with its General Counsel, revealing it had never taken place. This, OpenAI suggested, led to unnecessary misunderstandings and fueled the legal conflict. OpenAI published iMessage exchanges it says show Apple employees repeatedly asking Liu for help locating files and technical information after his January 22 departure, including directing a colleague to AirDrop files from his Apple-linked iCloud account. The same messages show an Apple employee still asking Liu about internal files as late as March 5, with another participant in the thread calling the exchange "highly irregular."
The blog included a series of email exchanges to support OpenAI’s position. It also highlighted flaws in Apple’s access management system, noting that when employees leave, they might still retain access to sensitive documents. OpenAI claimed this creates situations where former staff might unintentionally view confidential information, even without intent or awareness of access.
Focus on Key Individual and Accusations
One central figure in the dispute is Tang Tan, a long-time Apple employee with 24 years of experience. OpenAI defended him, stating that he had always made it clear to the team that OpenAI had no interest in using or even seeking out confidential data from Apple or other firms. His reputation at Apple as a respected and innovative leader was cited as proof of his integrity. Tang Tan co-founded io Products, the hardware startup that merged with OpenAI in July 2025.
OpenAI expressed disappointment that Apple had not reached out for a resolution before filing the lawsuit. The company accused Apple of making vague and broad claims about other former employees in a move it described as an attempt to shift blame and widen the legal battle. OpenAI suggested that Apple's actions were more focused on legal pressure and public perception than on uncovering the truth.
The blog post rejected Apple’s request for a preliminary injunction, calling it unnecessary and based on false information. OpenAI reaffirmed its position that it has no interest in Apple’s trade secrets and stressed its commitment to developing technologies that empower users globally. The company emphasized its focus on advancing innovation and expanding the possibilities in artificial intelligence.
By publishing this blog, OpenAI offered the most detailed response to date regarding the allegations. While not a formal legal response, it provides a structured and evidence-based rebuttal to Apple’s claims. The blog serves as a valuable source for those seeking to understand OpenAI’s perspective and the broader implications of the legal conflict. Apple has requested expedited discovery in the case and emphasized that "Apple will be irreparably harmed absent a preliminary injunction." Apple has now revealed that 11 other former employees could be witnesses or otherwise involved in the case. The company alleges that one former Apple employee met with Mr. Liu and Ms. Peng in advance of Ms. Peng’s interview at OpenAI and discussed Apple proprietary information relating to unannounced products. Another former Apple employee is said to have taken screenshots of confidential Apple documents relating to an unannounced product before an interview at OpenAI. After filing the lawsuit, multiple former Apple employees now working at OpenAI reached out to discuss returning Apple-issued work devices they kept when they left.
The dispute between two major tech firms continues to unfold, with OpenAI now making its position clearer and more defined. The blog post is a significant step in the company’s efforts to defend its reputation and counter the accusations made by Apple. It remains to be seen how this legal battle will develop next and what impact it might have on the tech industry.
For now, OpenAI has chosen to focus on explaining its stance rather than immediately entering formal legal proceedings. The blog, as well as Apple’s initial complaint, provide contrasting narratives that highlight the complexities of trade secret cases in the fast-moving field of artificial intelligence. Apple's complaint claims that more than 400 former Apple employees now work at OpenAI. The outcome of this case could set important precedents for future disputes in the tech world.
As both companies work through this legal issue, they will likely face increased public and industry scrutiny. The case raises questions about corporate ethics, data security, and the responsible use of confidential information. It also underscores the growing tension between Apple’s tightly controlled innovation and the open development approaches often seen in AI companies like OpenAI.
With OpenAI now speaking out more directly, the stage is set for further developments in this high-profile legal dispute. The blog has provided a more detailed defense from OpenAI, but the case is far from settled. As the situation continues to evolve, all eyes will be on how both companies navigate this complex and challenging situation.
