Apple filed a federal lawsuit against OpenAI on July 10 in the Northern District of California, alleging that the AI company systematically stole Apple’s hardware trade secrets — a stunning reversal for two companies that had publicly celebrated a landmark partnership less than two years earlier.
What Happened
Apple’s complaint alleges that OpenAI’s leadership — from technical staff to its Chief Hardware Officer — coordinated a scheme to extract confidential information from Apple employees who were interviewing at or transitioning to OpenAI. The filing names Tang Tan, a former Apple vice president who now serves as OpenAI’s hardware chief, as a central figure. According to Apple, Tan directed interviewing candidates to bring “actual parts” from Apple to interview sessions for “show and tell” demonstrations of Apple’s internal engineering work.
Apple further alleges that OpenAI coached departing employees on how to evade Apple’s internal security protocols when leaving the company. In one specific claim, the complaint identifies a former employee, Chang Liu, who Apple says stole an Apple laptop before departing for OpenAI. The lawsuit states the scheme operated “at every level, from members of its Technical Staff to its Chief Hardware Officer, and in coordination with business partners.”
Why It Matters
The lawsuit is significant on multiple levels. Apple and OpenAI announced a high-profile commercial partnership in 2024, when ChatGPT was integrated into iOS and Apple Intelligence. The relationship gave OpenAI distribution across hundreds of millions of Apple devices — a deal that helped legitimize ChatGPT as a mainstream consumer product and accelerated OpenAI’s path toward profitability. Apple’s decision to sue in federal court signals a fundamental breakdown in that relationship and raises questions about the future of the ChatGPT-iOS integration.
The timing is also notable for OpenAI, which is gearing up for what is expected to be one of the largest technology IPOs in history. Trade secret litigation of this scale — with allegations involving coordinated misappropriation directed from leadership — represents a material legal risk that prospective investors will need to assess. OpenAI has also recently been in discussions about offering the US government an equity stake as part of a broader strategy to position itself as a national strategic asset ahead of the public offering, making a high-profile lawsuit from one of America’s most recognizable corporations an unwelcome complication.
Background & Context
Trade secret litigation in Silicon Valley is not new — the landmark Waymo v. Uber case, which settled for $245 million in 2018, remains the most prominent precedent — but a case between two of the world’s most valuable technology companies, involving hardware design intellectual property and alleged employee-directed espionage, is rare in its scope and ambition. Apple’s complaint does not specify exact damages but trade secret cases involving deliberate misappropriation can carry substantial financial penalties under the Defend Trade Secrets Act.
The alleged hardware focus is particularly significant. Apple has been investing heavily in custom silicon for AI inference, including a recently renewed chip partnership with Broadcom focused on AI server applications. If OpenAI gained access to Apple’s proprietary hardware or chip designs, the competitive implications could extend well beyond the immediate lawsuit — particularly if OpenAI is developing its own consumer AI hardware, as multiple reports have suggested.
Apple itself is no stranger to legal battles in this period. Apple recently lost its legal challenge against the EU’s Digital Markets Act classification of iOS and the App Store as gatekeeper services — a ruling that could require structural changes to how the company operates in European markets. The combination of an offensive lawsuit against OpenAI and defensive litigation in Europe paints a picture of a company willing to fight on multiple fronts simultaneously to protect its competitive position.
What Comes Next
OpenAI had not issued a detailed public response to Apple’s complaint as of the time of writing. Cases of this complexity typically take months to reach pre-trial motion stages, and both companies will likely engage in extensive discovery processes. The case will be closely watched by the broader technology industry as a test of how courts handle trade secret allegations involving AI hardware — a category of intellectual property that did not exist in its current form when most leading legal precedents were established.
For Apple, the lawsuit marks a significant strategic statement: the company views its investments in AI hardware as core competitive assets to be protected aggressively, even at the cost of a partnership that gave ChatGPT its widest mainstream distribution channel. Whether that calculation proves correct will likely depend not just on court outcomes, but on whether OpenAI’s reported consumer hardware ambitions materialize into products that compete directly with Apple’s device ecosystem.
