OpenAI rebuts Apple trade secrets allegations in new response and evidence

OpenAI has published a detailed blog post rebutting many of Apple’s claims after Apple filed a lawsuit against OpenAI last month. Apple accused the firm behind ChatGPT of stealing trade secrets related to hardware development. Nearly a month after that filing, OpenAI’s response lays out its side of the dispute and addresses a large share of the allegations Apple brought.

The dispute centers on alleged misuse of confidential know-how tied to hardware development, not on a public product release or a shared software API. OpenAI’s reply is structured as a public, claim-by-claim style response backed by evidence rather than a short denial. That format matters because trade-secret cases often turn on what was shared, under what controls, and whether any protected material was used in a competing effort. A blog post that engages many of Apple’s specific claims signals OpenAI is trying to frame the factual record outside the courtroom as well as inside it.

For engineers and builders, the case is a reminder that hardware-adjacent work—device design, silicon choices, form-factor research, and related R&D—can become litigation risk when people, partners, or prior employment touch both companies. Teams shipping AI products that sit next to phones, wearables, or other consumer hardware should treat access controls, clean-room practices, and documentation of independent development as operational requirements, not legal afterthoughts. Hiring from a rival’s hardware groups, or collaborating across product lines, now carries clearer visibility risk because both Apple and OpenAI are airing parts of the fight in public.

Competitively, the suit puts two of the most influential consumer-tech players in direct conflict: Apple as a hardware and platform company, and OpenAI as the company behind ChatGPT and a major force in generative AI. Allegations about hardware trade secrets sit at the intersection of on-device AI, assistant experiences, and who controls the stack from model to silicon. A public rebuttal from OpenAI keeps the dispute in the news cycle and pressures both sides to defend their narratives with customers, partners, and regulators watching.

What to watch next is whether Apple’s complaint and OpenAI’s evidence-backed response narrow the issues or expand discovery into hardware roadmaps and personnel histories. Builders should track how courts treat trade-secret claims in AI-plus-hardware settings, and whether either company changes hiring, contractor, or partner practices as the case proceeds. Until more court filings or official statements surface, treat both the original Apple allegations and OpenAI’s blog-post rebuttal as contested positions, not settled fact.
