According to PANews on December 1, Musk's lawyers have filed for a preliminary injunction against OpenAI, several of its co-founders, and its investor and close collaborator Microsoft to prevent OpenAI and other defendants from engaging in anti-competitive behavior as claimed by Musk's lawyers.

The motion for the injunction was submitted to the U.S. District Court for the Northern District of California late last Friday, accusing OpenAI, its CEO Sam Altman, President Greg Brockman, Microsoft, LinkedIn co-founder and former OpenAI board member Reid Hoffman, and former OpenAI board member and Microsoft Vice President Dee Templeton of engaging in various illegal activities and attempting to obstruct these activities. The allegations include:

  1. Prevent investors from supporting OpenAI's competitors, such as Musk's own AI company xAI.

  2. Benefit from 'improperly obtained competitive sensitive information' through the relationship between OpenAI and Microsoft.

  3. Transform OpenAI's governance structure into a for-profit entity and 'transfer any significant assets, including intellectual property owned, held, or controlled by OpenAI, its subsidiaries, or affiliates.'

  4. Engage in business with organizations that have 'significant economic interests' with any defendant.

Musk's lawyers claim that if the injunction is not granted, it will cause 'irreparable harm.'
