Stability AI Prevails in UK Court Against Getty Images' Copyright Infringement Claims

Background of the Case

In January 2023, Getty Images initiated legal proceedings against Stability AI in the UK High Court, alleging that Stability AI had unlawfully used millions of Getty's copyrighted images to train its AI model, Stable Diffusion. Getty contended that this unauthorized use constituted a "brazen infringement" of its intellectual property on a massive scale. (independent.co.uk)

Key Developments During the Trial

During the trial, several pivotal developments occurred:

• Withdrawal of Primary Copyright Claims: Getty Images withdrew its primary copyright infringement claims, citing insufficient evidence to prove that the training of Stable Diffusion occurred within the UK jurisdiction. This strategic move allowed the court to focus on other aspects of the case. (techcrunch.com)

• Focus on Secondary Infringement and Trademark Claims: The court examined whether the Stable Diffusion model itself could be considered an "infringing copy" under UK law and whether the presence of Getty's watermarks on AI-generated images constituted trademark infringement. (dentons.com)

Court's Ruling

On November 4, 2025, the UK High Court delivered its judgment:

• Secondary Copyright Infringement: The court determined that the Stable Diffusion model does not store or reproduce copyrighted works and, therefore, is not an "infringing copy" under the Copyright, Designs and Patents Act 1988. Consequently, Stability AI was not liable for secondary copyright infringement. (dentons.com)

• Trademark Infringement: The court found that earlier versions of Stable Diffusion (v1.x and v2.x) had generated images containing Getty's watermarks, leading to limited instances of trademark infringement. However, these findings were described as "historic and extremely limited in scope," with no evidence that current versions of the model produce such watermarked images. (trowers.com)

Implications for the AI Industry

This ruling has several significant implications:

• Clarification on AI Training Practices: The decision provides clarity on the legality of using copyrighted materials for training AI models, particularly when the training occurs outside the UK. It suggests that AI developers may not be held liable for copyright infringement if their models do not store or reproduce the original copyrighted works. (dentons.com)

• Trademark Considerations: The court's acknowledgment of limited trademark infringement underscores the importance for AI developers to ensure that their models do not generate outputs containing identifiable trademarks without authorization.
