US judge permits authors to jointly sue Anthropic over copyright infringement

A US judge has cleared the way for a group of writers to sue AI company Anthropic over claims their books were used without permission to train an artificial intelligence model.

The decision means the authors can proceed as a group in a class action lawsuit. It is the latest sign that tensions are boiling over between artists and AI firms that rely on vast amounts of online content, often created by real humans, to make their bots smarter.

The authors, all published professionals, say Anthropic trained its Claude chatbot on their copyrighted books without asking or paying. They argue the company crossed the line by using their stories to teach AI how to sound more human, even mimicking their styles and ideas.

Judge says authors can band together against Anthropic

Judge Vince Chhabria, sitting in San Francisco, ruled that the authors shared enough in common to make the case a class action. That’s big. It means this won’t be dozens of separate, drawn-out lawsuits; instead, one case, with collective weight.

The core questions? Did Anthropic actually copy their work? And if it did, was that use “fair,” or did it break copyright law?

Anthropic had hoped to knock the case down before it got off the ground by insisting each writer should sue separately, but the judge did not buy it. He said the underlying issues were basically the same, and better dealt with all at once. This puts more legal heat on AI developers, many of whom are already under scrutiny for how they gather the data that trains their tools.

The lawsuit is far from an isolated incident. Around the world, creative professionals are pushing back against what they see as unauthorized and unfair use of their work by AI companies.

Getty Images is currently in a fierce battle with Stability AI over claims that millions of its photos were used without a license. In the music world, big record labels are suing companies making AI-generated songs. Music publishers have accused AI firms, including Anthropic, of using copyrighted music lyrics in training Claude.

And over in Hollywood, studios like Disney are accusing Midjourney of borrowing too freely from their film characters. The trend is clear: creators are drawing lines in the sand. And the tech world is being forced to listen.

AI firms, Anthropic included, say they are just “learning”

Anthropic and others in the industry argue that they are not stealing, but they are training. They say the process is a lot like how a person reads a ton of books and then writes something in their own words. According to this logic, the AI is not copying, but is learning.

OpenAI CEO Sam Altman has made that case publicly. Without copyrighted material, he has said, the world would not have tools like ChatGPT at all. But many artists are not buying it, especially when the AI-generated output feels eerily close to the original source.

It is one thing to be inspired, while it is another to blur the line between borrowing and ripping off. With the class action now moving forward, more authors could join the case. If the group wins, it could lead to financial compensation and maybe even force AI companies to rethink how they gather training data.

This legal battle is not just about books or bots. It is about who gets to profit from human creativity, and whether machines should be allowed to learn from art without consent.

As the AI boom races ahead, courts will likely play a huge role in deciding where the boundaries lie. The case could determine how AI firms approach copyrighted work when training their AI models going forward. And for now, writers are fighting to make sure they are not erased in the process.
