A US judge ruled in favor of Thomson Reuters, establishing a significant precedent in AI copyright law. The ruling affirmed that Westlaw, Reuters' legal research platform, doesn't infringe copyright by using data from rival legal databases like Casetext to train its generative AI models. The judge found the copied material constituted fair use because the AI uses the data differently than the original databases, transforming the information into new formats and features. This decision indicates that using copyrighted data for AI training might be permissible if the resulting AI product offers a distinct and transformative function compared to the original source material.
HN commenters generally agree that Westlaw's terms of service likely prohibit scraping, regardless of copyright implications. Several point out that training data is generally considered fair use, and question whether the judge's decision will hold up on appeal. Some suggest the ruling might create a chilling effect on open-source LLMs, while others argue that large companies will simply absorb the licensing costs. A few commenters see this as a positive outcome, forcing AI companies to pay for the data they use. The discussion also touches upon the potential for increased competition and innovation if smaller players can access data more affordably than licensing Westlaw's content.
