Apple vs OpenAI: Why the lawsuit could become Sam Altman's biggest hardware setback yet

Apple has filed a lawsuit accusing OpenAI and two former Apple employees of unlawfully obtaining confidential company information, opening a new front in the increasingly competitive race to build AI-powered consumer hardware.

The lawsuit targets Tang Tan, OpenAI's chief hardware officer and a former Apple vice president who spent 24 years at the company, along with Chang Liu, another former Apple employee who later joined OpenAI. Apple alleges the pair were involved in the improper acquisition and use of confidential information related to unreleased products, manufacturing techniques and internal engineering processes.

The legal action comes at a crucial time for OpenAI, which has been aggressively expanding its hardware ambitions following its acquisition of Jony Ive's startup, io. Although Ive is not named in the lawsuit, the dispute lands just as OpenAI is assembling a team of former Apple engineers to build what many believe could become a new generation of AI-first consumer devices.

Apple alleges recruitment was used to obtain confidential information

According to Apple's complaint, OpenAI's recruitment of Apple engineers went beyond hiring talent and crossed into the acquisition of proprietary information.

Among the central allegations is Apple's claim that Tang Tan instructed Apple employees interviewing with OpenAI to bring physical Apple components to interviews. According to the filing, those "show and tell" sessions were allegedly used to extract confidential technical knowledge.

Apple further alleges that OpenAI advised departing Apple employees on how to avoid the company's internal security procedures designed to safeguard sensitive information. In a separate claim, the company accuses Chang Liu of taking an Apple-issued laptop after leaving the company.

An Apple spokesperson told CNBC that the lawsuit follows the discovery of what it described as significant new evidence.

"Recently, significant evidence has emerged suggesting individuals employed by OpenAI wrongfully took Apple's secret and confidential information regarding our unreleased technologies, processes, and products," the spokesperson said.

The complaint goes beyond broad claims of trade secret theft, identifying specific proprietary technologies, including specialised metal finishing techniques that Apple says it developed and carefully protected.

Hardware ambitions could face fresh uncertainty

The lawsuit has the potential to extend far beyond a courtroom dispute over intellectual property. OpenAI has been steadily positioning itself as a future hardware company, bringing together experienced Apple veterans under the leadership of Jony Ive to develop AI-native consumer devices.

Industry observers believe Apple sees that effort as a genuine competitive challenge. Bloomberg's Mark Gurman has reported that Apple views OpenAI's hardware programme as one of the most credible emerging threats because it combines some of the world's leading hardware engineers with advanced AI capabilities. A successful legal challenge could therefore slow, reshape or significantly complicate OpenAI's efforts to bring rival consumer devices to market.

The timing is also significant. The lawsuit comes weeks after reports suggested OpenAI had considered legal action against Apple over disagreements surrounding their ChatGPT partnership. While the two matters are unrelated, the latest case underscores how relations between the companies have become increasingly strained despite their ongoing collaboration in artificial intelligence.

Apple's filing leaves little room for ambiguity about the seriousness of its accusations.

"This much is clear, however: at every level, from members of its Technical Staff to its Chief Hardware Officer, and in coordination with business partners, OpenAI has been stealing Apple's trade secrets and confidential information," the company said in the legal filing.

If Apple's claims are upheld, the consequences could extend beyond financial damages. The litigation could delay product development, disrupt recruitment efforts and force changes to OpenAI's hardware strategy at a time when the company is attempting to expand beyond AI software into consumer electronics.

For Apple, the lawsuit reinforces its determination to protect its intellectual property as competition in artificial intelligence intensifies. For OpenAI, it represents one of the most significant legal challenges yet to its long-term vision of building the next generation of AI-powered devices.
