Meta and CEO Mark Zuckerberg are facing renewed legal challenges over the company’s use of copyrighted material in artificial intelligence training. Major publishers and author Scott Turow have filed a class-action lawsuit in a US federal court, alleging that Meta used copyrighted books and academic works without permission to train its Llama large language models.

Key Highlights

• Meta and Mark Zuckerberg face a new US lawsuit over AI training with copyrighted materials.
• Publishers and author Scott Turow allege Meta used books and academic works without permission.
• Plaintiffs seek damages and broader representation for copyright holders in the legal case.
• Meta argues its AI practices are legal and plans to contest the copyright violation claims.
• Other AI firms, including OpenAI, are also involved in major legal disputes over similar issues.

Details of the Lawsuit

The lawsuit was filed in Manhattan federal court. Plaintiffs include Hachette, Macmillan, McGraw Hill, Elsevier, Cengage, and Scott Turow. They claim Meta copied and distributed millions of copyrighted works without authorization or compensation. The complaint also alleges that Mark Zuckerberg directly approved these practices.

The plaintiffs argue that Meta relied on pirated materials, such as textbooks, research papers, and novels, to train its AI systems. They are seeking damages and want the case expanded to represent a wider group of copyright holders.

Context and Industry Response

This is not the first time Meta’s AI training methods have faced legal scrutiny. Previous lawsuits have made similar allegations, but authors have not always succeeded in proving copyright infringement. Other AI firms, including Anthropic, have also faced lawsuits. Courts have given mixed responses, sometimes suggesting piracy-related arguments may be stronger than general copyright claims.

Meta maintains that its AI training practices are legal. The company argues that using copyrighted material for training can fall under fair use. Meta has stated it will contest the latest claims in court.

Related Legal Actions in AI

Other major legal battles are unfolding in the AI sector. OpenAI and Elon Musk are involved in a high-profile lawsuit. Musk has sued OpenAI and CEO Sam Altman, alleging the company shifted to a for-profit model to generate revenue, moving away from its original mission to help humanity. Musk seeks damages and the removal of Altman and Greg Brockman from OpenAI leadership.

These cases highlight ongoing legal uncertainties around AI training practices and the use of copyrighted material. The outcomes could set important precedents for technology companies and content creators.
