Anthropic’s Supporters Tell Court “Novel” Fair Use Arguments Put Forward by Music Publishers Are “Unconstitutional”

Key Takeaways

• Tech trade groups and scholars back Anthropic’s fair‑use claim
• Publishers allege AI training dilutes market for original lyrics
• EFF references Betamax case to argue against expanding copyright
• Ruling will guide licensing negotiations between AI firms and music owners

Pulse Analysis

The clash between Anthropic and major music publishers reflects a broader legal battle over how copyright law applies to generative AI. As AI models like Claude ingest vast corpora of copyrighted lyrics, companies argue that such training is a transformative, non‑commercial use protected by the fair‑use doctrine. Opponents, led by ABKCO, Concord and Universal, contend that the resulting AI‑generated songs compete with human‑created works, creating market dilution that outweighs any fair‑use justification. Their novel “dilution” theory seeks to extend copyright protection to entire genres, a move the Electronic Frontier Foundation warns could echo the failed Betamax arguments of the 1980s.

Legal scholars supporting Anthropic, including Harvard’s Rebecca Tushnet and Santa Clara’s Edward Lee, emphasize that copyright law historically favors competition and innovation. They argue that the publishers’ approach stretches the doctrine beyond its constitutional limits, attempting to grant a monopoly over ideas rather than expression. The Betamax precedent, where the Supreme Court rejected a similar expansion of copyright to curb new technology, is cited as a cautionary tale: courts should not rewrite copyright to stifle emerging tools. This perspective underscores the tension between protecting creators’ revenues and preserving the public’s right to build upon existing works.

The outcome of this case will have immediate commercial ramifications. A ruling favoring Anthropic could embolden AI firms to rely on fair‑use defenses, reducing the urgency for costly licensing deals and potentially exposing publishers to billions in lost royalties. Conversely, a decision that upholds the dilution argument may force AI companies into extensive licensing negotiations, reshaping revenue streams across the music ecosystem. Stakeholders across tech, entertainment, and law are watching closely, as the precedent set here will likely influence dozens of parallel lawsuits and the future trajectory of AI‑driven creativity.
