What is the case about?
It is alleged that Meta knowingly acquired and used copyright works, without authority or licence, for the training of its Llama 4 AI model. The source of those works is believed to be a Russian-compiled literary database known as “LibGen”, containing approximately 7.5 million copyright works.
The proposed action will seek damages and other remedies for the unlawful acquisition and use of copyright-protected works.
Why this matters for authors?
Copyright law exists to protect investment, labour and skill in original works, including original literary works under the Copyright, Designs and Patents Act 1988.
Infringement of copyright is actionable by the copyright owner and a claim would seek damages on behalf of authors affected by the infringement.
Who is bringing the claim?
Forum Chambers: specialist intellectual property barristers.
Humphries Kerstetter LLP: London law firm with extensive experience in group/collective redress claims.
How will the claim be funded?
The proposed action will be funded by a third‑party litigation funder.
