Author Art Kleiner filed a proposed class-action lawsuit against Adobe on February 11, 2026. The complaint alleges the company utilized copyrighted books without permission to train its SlimLM small language models.
The litigation challenges Adobe’s public commitment to ethical AI development, a stance the company previously emphasized regarding its Firefly image generator. This suit contributes to a broader trend of legal challenges facing technology firms over generative AI training data.
Analyst commentary released the same day noted that fears of AI disruption have recently pressured Adobe’s stock price. While analysts maintain the company’s fundamentals remain strong, the combination of legal risks and AI-related business uncertainty is creating significant market headwinds.
