Legal Action Taken

OpenAI and io Products Inc., an AI hardware startup OpenAI acquired for $6.5 billion in May, filed a notice of appeal Thursday in the US District Court for the Northern District of California. The company’s seeking Ninth Circuit review of the California court’s June 20 decision granting IYO a temporary restraining order, leading OpenAI to remove promotional materials about the Io partnership from its website.

IYO sued OpenAI over its use of the 'io' name, which has led to a legal battle between the two AI companies. OpenAI is known for its AI-powered legal analytics, workflow tools and premium legal & business news.
