In brief
- OpenAI published a detailed rebuttal to Apple's trade secrets lawsuit.
- The company says Apple misstated key facts before filing suit and released emails to support its claims.
- OpenAI also argues Apple employees continued seeking help from a former engineer after he joined the company.
OpenAI has publicly challenged Apple's trade secrets lawsuit, publishing emails, text messages, and a point-by-point rebuttal that accuses the iPhone maker of making factual errors before filing its complaint.
In a blog post published Monday, OpenAI said Apple confused two employees with similar names, falsely claimed the company ignored its outreach, and incorrectly asserted that Apple's outside counsel had spoken with OpenAI General Counsel Che Chang before filing a lawsuit against OpenAI.
The email and text dump comes after Apple sued OpenAI in July, accusing the company, former Apple engineer Chang Liu, former Apple design executive Tang Tan, and io Products of misappropriating hardware trade secrets as OpenAI expanded its consumer hardware efforts following its acquisition of Jony Ive's startup in 2025.
“Apple is one of the greatest companies of all time, and built a reputation for obsessing over the smallest details,” OpenAI wrote. “This careless, aggressive and oddly personal lawsuit sadly doesn’t live up to that reputation.”
In its lawsuit, Apple accuses former Apple engineer Chang Liu of retaining a company laptop after leaving, exploiting an authentication bug to access Apple's internal systems, and downloading confidential engineering documents. The lawsuit also claims former Apple executive Tang Tan used confidential Apple information to benefit OpenAI's hardware efforts and that the company's recruiting process encouraged prospective hires to bring sensitive Apple materials.
OpenAI disputes those allegations, saying Apple contacted the wrong person after confusing two employees with similar surnames and incorrectly claimed its lawyers had spoken with OpenAI General Counsel Che Chang before filing suit.
To support its case, OpenAI published iMessage exchanges between Liu and Apple employees sent after he left the company in January, showing them asking for help locating files, transferring documents, and answering technical questions—conversations OpenAI says undermine Apple's claims that Liu improperly retained access to confidential information.
According to OpenAI, those exchanges show Apple employees relied on Liu's access and that any remaining access resulted from Apple's own offboarding process rather than deliberate misconduct.
As for Tan, OpenAI says the former Apple executive was repeatedly instructed not to bring or use confidential information from his previous employer. The company also argues Apple's request for a preliminary injunction, which could restrict OpenAI's activities while the case proceeds, is unnecessary.
“Apple’s request for a preliminary injunction is both based on false information and completely unnecessary because we do not have, nor want, any of their trade secrets,” the company wrote. “We’re much more interested in building innovative products and technologies that push the frontier.”

Executive Summary
Apple is currently engaged in a legal battle with OpenAI over allegations of misappropriating hardware trade secrets. Apple contends that former employees Chang Liu and Tang Tan improperly transitioned sensitive engineering and design information to OpenAI during the latter's expansion into consumer hardware following the 2025 acquisition of Jony Ive's startup. Specifically, Apple points to unauthorized system access and the retention of company hardware as evidence of misconduct.
OpenAI has responded by publicly challenging the factual basis of the lawsuit. Through a release of internal communications, OpenAI argues that Apple's claims are marred by administrative errors—such as confusing employees with similar names—and that Apple employees continued to rely on Chang Liu's expertise post-employment. OpenAI maintains that any remaining system access was a failure of Apple's own offboarding processes rather than a deliberate breach. While Apple seeks a preliminary injunction to protect its intellectual property, OpenAI asserts such measures are unnecessary as they have no interest in Apple's trade secrets.
Full Take
The strongest version of this narrative is a classic corporate clash over "talent poaching" and intellectual property boundaries, where a legacy giant attempts to protect its moat against a disruptive challenger. OpenAI's strategy is not merely legal but communicative; by "dumping" emails and texts, they are attempting to shift the public perception of Apple from a meticulous innovator to a "careless" litigator.
The narrative relies heavily on a pattern of juxtaposition: contrasting Apple's reputation for "obsessing over the smallest details" with the alleged factual errors in their legal filings. This serves to undermine the credibility of the entire lawsuit by highlighting specific, easily verifiable clerical mistakes.
Patterns detected: none
The root cause is the intensifying arms race in AI-integrated hardware. As OpenAI moves from software into the physical realm, the "human capital" bridge—engineers moving between firms—becomes the primary vector for technology transfer. This echoes the historical "Employee Raiding" battles of the Silicon Valley era, where the line between an individual's professional expertise and a company's trade secret is perpetually blurred.
The implication is a chilling effect on labor mobility. If "offboarding failures" are litigated as "misappropriation," employees may face heightened liability for simple administrative oversights. The benefit accrues to the entity capable of sustaining the most aggressive legal posture.
If this were a coordinated influence campaign, the playbook would involve "leak-driven delegitimization"—releasing selective communications to make a sophisticated opponent look incompetent before the case ever reaches discovery. The current content follows a standard corporate PR rebuttal format and does not exhibit the hallmarks of a coordinated psychological operation.
Bridge Questions:
How does the industry distinguish between a "trade secret" and the general professional competence of a high-level engineer?
If Apple's offboarding process was indeed flawed, does that absolve the employee of the responsibility to return company hardware?
What evidence would be required to prove that a recruiting process "encourages" the theft of secrets versus simply hiring the best talent in a field?
