OpenAI has flipped the script on Apple’s trade-secret lawsuit, publishing a detailed rebuttal, complete with private emails and text messages, that calls the suit “careless, aggressive, and oddly personal.” The move escalates a growing feud between the two companies. Apple, meanwhile, has fired back with a motion for a preliminary injunction, and a court has ruled on none of it.

Key Takeaways

• OpenAI publicly rebutted Apple’s July trade-secret lawsuit
• It called the suit “careless, aggressive, and oddly personal”
• OpenAI published private emails and texts to counter Apple’s claims
• Apple filed a motion for a preliminary injunction against OpenAI
• All allegations remain unproven, with no court ruling yet

What OpenAI Said

On August 3, 2026, OpenAI published a blog post titled “Apple is getting this wrong,” responding to the lawsuit Apple filed in July. The tone was pointed: OpenAI described the suit as careless, aggressive, and oddly personal, while calling Apple “one of the greatest companies of all time.”

The core of OpenAI’s response:

• It said Apple’s injunction request is “based on false information and completely unnecessary” because it doesn’t have and doesn’t want Apple’s trade secrets
• It said it has “no interest in other companies’ trade secrets”
• It published iMessage and email exchanges it argues challenge Apple’s version of events
• The post was signed by the company rather than a named executive

It’s worth stating clearly that these are competing claims in active litigation. A court has not ruled on the allegations, and OpenAI’s published messages represent its side of a contested dispute.

The Background to the Suit

Apple filed its lawsuit on July 10, 2026, in California, and the stakes tie directly to Apple’s and OpenAI’s rivalry in consumer hardware. Apple alleged OpenAI conspired with former Apple employees to misappropriate trade secrets related to unreleased technologies.

The two individuals at the center of Apple’s complaint:

• Tang Yew Tan (Tang Tan): A former Apple design executive of more than 24 years, whom Apple describes as a chief hardware figure, now at OpenAI
• Chang Liu: A former Apple engineer whose last day was January 22, 2026

Apple’s specific allegations, which OpenAI denies:

• That Liu failed to return a work laptop, exploited an authentication bug, and downloaded dozens of confidential hardware-related files
• That Tan directed job candidates still at Apple to bring “actual parts” to show OpenAI personnel at interviews
• That OpenAI’s recruitment process doubled as a way to collect Apple’s proprietary information to aid its hardware ambitions

OpenAI’s Rebuttals

OpenAI’s response went point by point, and the published communications are its central evidence. Here is how it addressed the main claims:

• On Chang Liu’s access: OpenAI says Apple now admits its own employees reached out to Liu asking for help locating certain information after he had left, and that Apple tried to “shift the blame to ‘residual access'” caused by its own failure to manage system access when people leave
• On Tang Tan: OpenAI says Tan was always clear with his team that the company does not want and must not use confidential information from other firms
• On the February contact: OpenAI disputes Apple’s claim that it contacted OpenAI in February and got no response, saying Apple’s outside counsel emailed the wrong person after confusing two Asian last names, and only admitted the error after OpenAI pointed it out
• On follow-up: OpenAI says Apple never raised the specific allegations in the complaint beforehand, telling OpenAI only that it was “resolving any issues” before suing five months later

Apple’s Countermove

Apple has not backed down. On the same Monday timeframe as OpenAI’s post, Apple escalated on the legal front.

Apple’s filings:

• A motion to bar the two former employees and OpenAI from accessing, using, or disclosing the alleged confidential information, per Reuters
• A motion for expedited discovery, including production of documents relating to the defendants’ alleged access of Apple’s confidential information
• An argument that Apple would be “irreparably harmed” absent an injunction

The suit names OpenAI, its hardware unit io Products, and the two former employees. Apple maintains the alleged conduct benefited OpenAI’s breakout into consumer hardware.

A Pattern of Talent-War Lawsuits

This dispute doesn’t exist in isolation. It reflects a broader wave of litigation as AI companies poach top talent from one another.

The wider legal landscape:

• OpenAI previously defended itself against similar trade-secret allegations brought by Elon Musk’s xAI, which OpenAI called an attempt to “intimidate” it and distract from xAI’s own competitive shortcomings
• xAI has separately sued Apple, alleging it conspired with OpenAI to suppress rival platforms, which Apple and OpenAI deny
• Musk is also suing OpenAI over its conversion to a for-profit, and OpenAI has countersued Musk for harassment

The pattern is clear: as OpenAI scales and attracts talent from competitors, those competitors increasingly turn to the courts.

Why It Matters

The clash marks a dramatic escalation between two companies whose relationship has grown increasingly tense. OpenAI’s decision to publish private communications, rather than issue a brief statement, signals it intends to fight this publicly and aggressively.

The broader stakes:

• Legal risk for OpenAI: The suit adds to a growing pile of litigation as OpenAI’s stock-market debut reportedly slips toward 2027
• The hardware angle: Both companies are racing into AI-powered consumer devices, making the disputed knowledge genuinely valuable
• The talent war: The case underscores how aggressively AI firms now litigate over the engineers moving between them

For now, this is a public-relations and legal offensive from OpenAI against unproven allegations, met by Apple’s push for a court injunction. Nothing has been decided, and both sides are presenting selective evidence. How a judge weighs Apple’s injunction motion will be the next real signal of where this heads.

A note for readers following the story: this is the latest development in an ongoing Apple-OpenAI dispute, and the earlier filings and OpenAI’s initial response provide useful context worth revisiting alongside this piece.
