In a 4 November 2025 judgment, the UK High Court found that Stability AI is not liable for secondary copyright infringement in the UK, holding that the trained Stable Diffusion model does not constitute an "infringing copy" because model weights never stored or contained copies of copyright works, even though training used copyrighted images. Getty withdrew primary infringement claims (training within UK) due to insufficient evidence and abandoned output infringement claims after blocking disputed prompts. The court confirmed electronic copies in intangible media can be "articles" under copyright law, and downloads of the model into the UK amount to importation, but the model itself is not tainted by upstream training activity. This creates a territorial gap: UK rightsholders now lack a mechanism to prevent models trained outside the UK from being commercialized in UK, and are worse off than EU rightsholders who benefit from AI Act compliance requirements.
