IP analysis: This appeal is part of a broader legal dispute over the alleged misuse of Getty Images (US), Inc's (‘Getty’) content by Stability AI Ltd (‘Stability’) to train its generative AI model, Stability Diffusion. In this particular claim, Getty alleged that the model's ability to generate offensive material, including pornography and child sexual abuse material (‘CSAM’), could tarnish Getty's brand. The High Court ruled that ‘pornography’ in Getty's pleadings excluded CSAM, thus preventing such material from being introduced. On appeal, Getty claimed the CSAM should be included. The Court of Appeal agreed that the High Court had misinterpreted the term and that CSAM did fall under the scope of ‘pornography’, but found that Getty's own pleadings explicitly excluded CSAM-related allegations. Therefore, the exclusion of CSAM evidence stood. This case highlights the importance of precise pleadings, especially in such complex litigation. Regardless of the fact that this particular case dealt with novel issues and technological context, the court will continue to enforce strict procedural boundaries, highlighting the importance of adhering carefully to court procedure.
