The race to build the most advanced artificial intelligence generative AI technology has continued to be a story about data: who possesses it, who seeks it, and what methods they use for its acquisition. A recent federal court ruling involving Anthropic, creator of the AI assistant Claude, offered a revealing look into these methods. The company received a partial victory alongside a potentially massive liability in a landmark copyright case. The legal high-five and hand slap draw an instructive, if blurry, line in the sand for the entire AI industry.
This verdict is complex, likely impacting how AI large language models (LLMs) will be developed and deployed going forward. The decision seems to be more than a legal footnote, but rather a signal that fundamentally reframes risk for any company developing or even purchasing AI solutions.

My Fair Library
First, the good news for Anthropic and its ilk. U.S. District Judge William Alsup ruled that the company’s practice of buying physical books, scanning them, and using the text to train its AI was “spectacularly transformative.” In the court’s view, this activity falls under the doctrine of “fair use.” Anthropic was not simply making digital copies to sell. In his ruling, Judge Alsup wrote that the models were not trained to “replicate or supplant” the books, but rather to “turn a hard corner and create something different.”
The literary ingestion process itself was strikingly industrial. Anthropic hired former Google Books executive Tom Turvey, to lead the acquisition and scanning of millions of books. The company purchased used books, stripped their bindings, cut their pages, and fed them into scanners before tossing the paper originals. Because the company legally acquired the books and the judge saw the AI’s learning process as transformative, the method held up in court. An Anthropic spokesperson told CBS News it was pleased the court recognized its training was transformative and “consistent with copyright’s purpose in enabling creativity and fostering scientific progress.”
For data and analytics leaders, this part of the ruling offers a degree of reassurance. It provides a legal precedent suggesting that legally acquired data can be used for transformative AI training.

However, the very same ruling condemned Anthropic for its alternative sourcing method: using pirate websites. The company admitted to downloading vast datasets from “shadow libraries” that host millions of copyrighted books without permission. Judge Alsup was unequivocal on this point. “Anthropic had no entitlement to use pirated copies for its central library,” he wrote. “Creating a permanent, general-purpose library was not itself a fair use excusing Anthropic’s piracy.”
As a result, Anthropic now faces a December trial to determine the damages for this infringement. This aspect of the ruling is a stark warning for corporate leadership. However convenient, using datasets from questionable sources can lead to litigation and reputational damage. The emerging concept of “data diligence” is no longer just a best practice, it’s a critical compliance mechanism.
A Tale Of Two Situs
This ruling points toward a new reality for AI development. It effectively splits the world of AI training data into two distinct paths. One is the expensive, but legally defensible route of licensed content. The other is the cheap, but legally treacherous path of piracy.
The decision has been met with both relief and dismay. While the tech industry now sees a path forward for AI training, creator advocates see an existential threat. The Authors Guild, in a statement to Publishers Weekly, expressed its concern. The organization said it was “relieved that the court recognized Anthropic’s massive, criminal-level, unexcused e-book piracy,” but argued that the decision on fair use “ignores the harm caused to authors.” The Guild added that “the analogy to human learning and reading is fundamentally flawed. When humans learn from books, they don’t make digital copies of every book they read and store them forever for commercial purposes.”
Judge Alsup directly addressed the argument that AI models would create unfair competition for authors. In a somewhat questionable analogy, he wrote that the authors’ argument “is no different than it would be if they complained that training schoolchildren to write well would result in an explosion of competing works.”
The Story Continues
This legal and ethical debate will likely persist, affecting the emerging data economy with a focus on data provenance, fair use, and transparent licensing. For now, the Anthropic case has turned a new page on the messy, morally complex process of teaching our silicon-based co-workers. It reveals a world of destructive scanning, digital piracy, and legal gambles. As Anthropic clawed its way through millions of books, it left the industry still scratching for solid answers about content fair use in the age of AI.
