The fight over who owns Apple’s hardware secrets has turned into a fight over how the lawsuit itself may be argued. Apple told a federal court this week that OpenAI is improperly adding new arguments to the trade-secrets case between the two companies, an accusation that keeps the dispute alive even as the two remain bound together by a multibillion-dollar deal over ChatGPT.
The case began when Apple sued OpenAI, alleging that former Apple engineers carried proprietary product designs, supplier information and other trade secrets into the startup when they joined it. Apple’s complaint was built around a narrow claim, one the company has repeated as the dispute has widened: that specific individuals took specific Apple trade secrets in specific ways. The phrasing matters, because it anchors the case in concrete acts rather than a general accusation of poaching.
OpenAI has called the suit meritless and moved to have it dismissed. In a public rebuttal titled “Apple is getting this wrong,” the company argued that Apple had not done enough to protect the information it now calls secret, and that much of what Apple describes as confidential was ordinary supplier relationships and parts anyone could buy. OpenAI has also said the former employees in question did nothing improper.
Apple’s latest filing pushes back on those arguments and, more sharply, on the idea that OpenAI can introduce them now. The company contends that OpenAI is adding new points that were not part of its original motion, according to AppleInsider, which reported the filing on Tuesday. In Apple’s telling, the motion to dismiss is being retooled on the fly, and the court should not weigh arguments the company never properly raised.
The procedural objection sits on top of a deeper standoff. Apple and OpenAI are partners and adversaries at once. Apple has built ChatGPT into its devices, and executives have described the arrangement as central to Apple’s AI strategy. A lawsuit over stolen trade secrets runs directly against that posture, and every filing in the case now doubles as a negotiation over how much of the relationship the two can salvage.
The individuals at the center of the case give the dispute its edge. Apple has pointed to a former engineer who later took a senior hardware role at OpenAI, and the complaint describes a pattern in which that person and others sought out Apple employees with access to sensitive designs. OpenAI has countered by publishing messages it says show Apple kept working with one of the engineers after the alleged conduct, a claim meant to undercut the idea that the information was ever treated as secret.
What Apple wants from the court now is comparatively modest: a ruling that keeps the case to the claims and arguments as they were filed. The stakes beneath that request are larger. A trade-secrets trial between two of the most visible companies in consumer technology would drag internal documents and deposition testimony into public view, and each side has an interest in controlling how much of that record gets built before a jury ever sees it.
For Apple, the case is a test of how aggressively it will defend its hardware pipeline at a moment when AI companies are hiring silicon and product designers at a pace the industry has rarely seen. For OpenAI, the case is a distraction from a rollout schedule that now runs through chips of its own, an effort that depends in part on the same kind of design talent Apple is accusing it of taking.
The companies have spent months fighting while continuing to do business. Neither has moved to unwind the ChatGPT integration that put the assistant on hundreds of millions of iPhones, and the commercial terms of that deal remain untouched. But a legal fight built on accusations of theft makes the partnership harder to explain in public, and the tone of the filings has grown sharper rather than softer.
The immediate question is procedural: whether the judge accepts Apple’s argument that OpenAI is shifting ground mid-case. The longer question is whether two companies that sell to each other can keep a product partnership alive while their lawyers accuse each other of bad faith in court. For now, the case that began as an argument about secrets has become an argument about how the argument itself is being waged.
The dispute arrives as both companies race toward hardware of their own. Apple’s custom silicon has long been a differentiator for the iPhone and Mac, and the company treats its chip road map as closely held. OpenAI, meanwhile, has begun building inference chips to reduce its dependence on outside suppliers, a project that needs exactly the kind of engineers the lawsuit is about. That overlap is what makes the litigation more than a routine squabble over ex-employees.
Neither company has signaled that the case will derail their product work. Apple continues to ship devices with OpenAI’s models inside, and OpenAI continues to describe the relationship as stable. But the filings tell a different story, one in which each side questions the other’s good faith in writing, and the argument about new arguments is only the latest turn.
