AI company Ross Intelligence loses copyright fight with Thomson Reuters

A US judge has ruled in favor of Thomson Reuters in a AI training fight against Ross Intelligence, a legal AI startup, according to The Verge. Thomson Reuters sued Ross Intelligence in 2020 for using the company’s legal research platform Westlaw to train Ross Intelligence’s AI without permission. Westlaw indexes large amounts of non-copyrighted material, but mixes it with its own content.

Ross Intelligence argued that the training should be classified under “fair use” practices, but the judge disagreed. Instead, the court held that Ross Intelligence’s use of the copyrighted material affected its original value because the company intended to develop a direct competitor.

The ruling is significant because it could have implications for future cases where copyrighted material is used for AI training. One wrinkle: this particular case concerned non-generative AI, which is not the same as generative AI used in large language models to create new material based on previous training data.
