Artificial intelligence company Stability AI largely emerged victorious in a British court battle with Getty Images over intellectual property rights.

Seattle-based Getty Images, which owns a vast online collection of images and videos, filed the lawsuit challenging Stability AI’s use of its library to train the Stable Diffusion AI model. The case, which went to trial at Britain’s High Court in June, was closely watched amid a global wave of copyright disputes involving AI training data.

According to Tuesday’s ruling, Getty secured a limited win on trademark infringement, but its claims of secondary copyright infringement were dismissed. Both parties declared partial victories.

“This is a significant win for intellectual property owners,” Getty said in a statement, though its U.S. shares fell 3% before the opening bell. Stability AI said it welcomed the ruling, noting that “the final decision resolves the core copyright concerns,” according to General Counsel Christian Dowell.

Justice Joanna Smith noted that Getty’s trademark claims were only partially successful and described the findings as “historic but extremely limited in scope.”

The ruling highlights the ongoing tensions between tech companies and creative industries over AI’s use of copyrighted works. Similar lawsuits are underway in the U.S., including cases against Stability AI, Midjourney, and Anthropic.
