LONDON - Getty Images' landmark copyright lawsuit against artificial intelligence company Stability AI begins at London's High Court on Monday, with the photo provider's case likely to set a key precedent for the law on AI.

The Seattle-based company, which produces editorial content and creative stock images and video, accuses Stability AI of breaching its copyright by using its images to "train" its Stable Diffusion system, which can generate images from text inputs.

Getty, which is bringing a parallel lawsuit against Stability AI in the United States, says Stability AI unlawfully scraped millions of images from its websites and used them to train and develop Stable Diffusion.

Stability AI – which has raised hundreds of millions of dollars in funding and in March announced investment by the world's largest advertising company, WPP – is fighting the case and denies infringing any of Getty's rights.

A Stability AI spokesperson said that "the wider dispute is about technological innovation and freedom of ideas," adding: "Artists using our tools are producing works built upon collective human knowledge, which is at the core of fair use and freedom of expression."

Getty's case is one of several lawsuits brought in Britain, the US and elsewhere over the use of copyright-protected material to train AI models, after ChatGPT and other AI tools became widely available more than two years ago.

Wider impact

Creative industries are grappling with the legal and ethical implications of AI models that can produce their own work after being trained on existing material. Prominent figures including Elton John have called for greater protections for artists.

Lawyers say Getty's case will have a major impact on the law, as well as potentially informing government policy on copyright protections relating to AI.

"Legally, we're in uncharted territory. This case will be pivotal in setting the boundaries of the monopoly granted by UK copyright in the age of AI," Rebecca Newman, a lawyer at Addleshaw Goddard, who is not involved in the case, said.

She added that a victory for Getty could mean that Stability AI and other developers will face further lawsuits.

Cerys Wyn Davies, from the law firm Pinsent Masons, said the High Court's ruling "could have a major bearing on market practice and the UK's attractiveness as a jurisdiction for AI development".
