The iPhone-maker claims OpenAI encouraged poached Apple employees to bring over confidential presentations, secret prototypes, and key supplier details. Apple filed a lawsuit against OpenAI and its hardware chief on Friday for allegedly stealing the iPhone-maker's trade secrets, including unreleased parts and prototypes, confidential designs, and documents about stealth projects. The lawsuit accuses OpenAI chief hardware officer Tang Tan, who spent 24 years at Apple and oversaw iPhone product design, and his colleagues at the AI company of encouraging people departing or considering leaving Apple to bring with them proprietary and unreleased technology. Tan allegedly helped coach recruits on how to evade Apple's data security protocols and directed them to bring confidential Apple parts to job interviews at OpenAI. "OpenAI's nascent hardware business now rests on the shakiest of foundations, rotten to its core by its illegal reliance on misappropriated trade secrets," Apple says in the lawsuit, which was filed in US district court in San Jose.

Sony Corp. and Line Corp., Japan's most popular messaging service, are considering joining forces to develop devices powered by artificial intelligence. The companies are exploring opportunities around digital personal assistant technology to co-create a new communication experience, Sony said in a statement at the Mobile World Congress in Barcelona on Monday. Sony unveiled concept earphones powered by Xperia Agent, a virtual butler that responds to voice commands and head gestures. While Sony's Xperia smartphones are an also-ran in a market dominated by Apple Inc. and Samsung Electronics Co., Chief Executive Officer Kazuo Hirai has resisted pressure to shutter the mobile business. He argues it will serve as a springboard into the nascent market for wearable and interconnected devices known as the Internet of Things.
