Thomson Reuters has achieved a significant victory in the realm of artificial intelligence and copyright law, marking the first major AI copyright case win in the United States. The decision stems from a lawsuit the company filed in 2020 against legal AI startup Ross Intelligence. Thomson Reuters accused Ross of unlawfully reproducing materials from its Westlaw legal research platform, and a judge has now ruled that this claim holds merit.
U.S. District Court Judge Stephanos Bibas delivered a decisive summary judgment, dismissing all of Ross Intelligence’s defenses. He firmly stated, “None of Ross’s possible defenses holds water,” reinforcing Thomson Reuters’ stance on copyright infringement.
This ruling has far-reaching ramifications, especially amid a surge of legal disputes concerning how generative AI companies use copyrighted content, which often includes works from books, music, and various forms of media. The ruling comes at a time when numerous cases are navigating the U.S. court system as well as facing challenges in other countries, including China, Canada, and the UK.
A crucial aspect of the ruling involved the fair use doctrine, a legal principle that can allow for limited use of copyrighted material without permission under specific conditions. In assessing fair use, courts typically consider four factors, including the purpose and character of the use, the nature of the copyrighted work, the amount of material used, and the effect on the market value of the original work. The court concluded that while Thomson Reuters succeeded on two factors, the most pivotal was that Ross intended to compete with Westlaw by creating a market substitute.
Thomson Reuters’ spokesperson, Jeffrey McCoy, expressed satisfaction with the judgment, emphasizing that the editorial content created by their attorneys is protected by copyright and cannot be utilized without consent, declaring that Ross’s replication of this content did not qualify as fair use.
The implications of this ruling are especially severe for Ross Intelligence, which had already shut down in 2021 as a result of the legal pressure and associated costs. Unlike smaller players, larger AI firms such as OpenAI and Google are more financially positioned to endure ongoing litigation.
Legal experts predict that this decision will complicate the landscape for generative AI companies, particularly regarding their arguments around fair use. Cornell University’s James Grimmelmann highlighted that if this ruling is mirrored in other cases, it could significantly hinder AI companies’ defenses citing fair use as a crucial safeguard against claims of unauthorized copyright use.
