US judge sides with Meta in AI copyright lawsuit

A US federal judge has ruled in favor of Meta Platforms in a lawsuit filed by authors who alleged the company infringed their copyrights by using their books to train its AI system, Llama.

US District Judge Vince Chhabria said that the plaintiffs did not provide enough evidence to show that Meta’s actions would harm the market for their works, a key factor under US copyright law.

He noted that using copyrighted materials for AI training could be unlawful in many situations, but the plaintiffs failed to support their claims.

The decision contrasts with a ruling earlier in the week where another judge found Anthropic’s use of copyrighted materials for AI training qualified as “fair use.”

Meta welcomed the ruling and emphasized the importance of fair use in AI development.

The lawsuit, filed in 2023, is part of a wider wave of copyright disputes targeting AI companies like OpenAI, Microsoft, and Anthropic.

🧠 Food for thought

1️⃣ Courts are establishing nuanced rather than sweeping AI copyright precedents

Recent rulings demonstrate that courts are carefully evaluating specific arguments and evidence rather than making broad proclamations about AI training legality.

Judge Chhabria explicitly stated his ruling “does not stand for the proposition that Meta’s use of copyrighted materials to train its language models is lawful” but rather that “these plaintiffs made the wrong arguments”1.

This contrasts with Judge Alsup’s decision on Anthropic, which found AI training was “quintessentially transformative” and constituted fair use, while simultaneously holding the company liable for using pirated books2.

The divergent rulings demonstrate how courts are establishing case-specific boundaries rather than one-size-fits-all precedents, focusing on the particular evidence and arguments presented in each case.

These early decisions suggest that the legality of AI training will develop through careful judicial analysis of specific circumstances rather than broad declarations about the technology as a whole.

2️⃣ Market impact emerges as a critical factor in AI copyright cases

Despite ruling for Meta, Judge Chhabria expressed significant concern about AI’s potential to undermine creative markets, highlighting how market impact is becoming central to these cases.
