Stability AI achieved a significant legal victory against Getty Images in a British court regarding the use of copyrighted material to train its AI model, Stable Diffusion. The UK High Court's decision, delivered by Judge Joanna Smith, ruled that while Stability AI did infringe Getty's trademark by generating images that included its watermarks, it did not commit secondary copyright infringement because the AI does not store or reproduce copyrighted works. This ruling leaves the central question of whether AI companies need permission to use copyrighted material for training unresolved. Getty Images initially pursued a more comprehensive claim focused on the legality of using its images for training AI but dropped this aspect during the trial due to insufficient evidence. The case marks a notable moment in the ongoing struggle between AI developers and creative rights holders, highlighting the legal uncertainty surrounding AI and copyright law in the UK. Getty Images has also filed a related lawsuit in the US, which was initially in Delaware but has since been refiled in California. The broader context includes other high-profile copyright disputes in the AI industry, such as Anthropic's $1.5 billion settlement with authors and Universal Music's decision to drop its claims against AI startup Udio. These developments reflect the complex and evolving landscape of copyright law as it intersects with AI technology.
