Status: confirmed
Sources: complaint (CourtListener), CNBC, HN discussion
Summary: Apple filed suit in the Northern District of California on 2026-07-10 (Apple Inc. v. Liu, 5:26-cv-07078) for trade-secret misappropriation and breach of contract against OpenAI Foundation, OpenAI Group PBC, io Products LLC, and two former Apple employees now at OpenAI: Chang Liu, a former senior systems electrical engineer, and Tang Yew Tan, OpenAI's hardware chief and former Apple VP of product design for iPhone and Apple Watch. The complaint alleges Liu skipped his exit interview, kept an Apple laptop, and used a bug to reach Apple internal cloud storage after leaving to download confidential files including over a thousand pages of technical documents, and that Tan directed Apple job candidates to bring "actual parts" to OpenAI interviews for show-and-tell.
Comments: HN commenters posted the complaint and highlighted the alleged instruction to recruits to email themselves confidential material and to conceal their OpenAI offers. Several framed it as competitive litigation echoing Apple v. Samsung.
Why it matters: The suit targets the talent and IP flow behind OpenAI's io Products hardware effort and marks a sharp break between two firms that partnered on Apple Intelligence in 2024.
