Apple sues OpenAI over alleged trade secret theft by ex-employees

OpenAI's legal troubles have multiplied throughout the year, but Apple's lawsuit represents a particularly high-stakes challenge because it targets the company's hardware ambitions at a critical moment. OpenAI has confidentially filed a Form S-1 with the SEC for a public offering and is under investor pressure to turn a profit. The hardware initiative, funded by OpenAI's nearly $6.5 billion（約1兆円） acquisition of Jony Ive's startup io, is central to the company's strategy to diversify beyond software — an area where it allegedly struggles relative to Apple's decades of expertise. The lawsuit directly threatens this path: Apple is known as a determined and stubborn litigant, and experts expect the case to stretch over years through discovery and potential appeals.

The broader context reveals that trade secret lawsuits are rampant in the AI industry, with Scale AI, xAI, and Tesla all pursuing similar cases against competitors or employees who left for rivals. What makes Apple's lawsuit noteworthy to legal observers is not the novelty of the allegations themselves — hiring-stage extraction, interview solicitation, and internal collusion are, as one cybersecurity researcher noted, "run-of-the-mill in terms of insider threats" — but rather that a major company like Apple is pursuing all of them together against another major player. The irony is not lost on legal experts that an AI industry built on consuming vast amounts of data aggressively polices when that information moves between companies. Still, the industry has historical precedent: pre-generative AI tech spent decades in similar disputes, from Google's book-scanning project to YouTube's early piracy enablement.
