The Delhi High Court has released what may be one of the most consequential copyright decisions yet on artificial intelligence, ruling in ANI Media Pvt. Ltd. v. OpenAI that OpenAI’s use of copyrighted news articles to train the models behind ChatGPT is prima facie fair dealing. The 135-page decision of Justice Amit Bansal, released last week, dismissed an Indian news agency’s application for an interim injunction, and while it is expressly not a final ruling on the merits, it features valuable analysis of the copyright implications of machine research, market harm and the public interest. The case is particularly notable from a Canadian perspective since it is the 2004 landmark CCH Supreme Court of Canada copyright case that provides the decision’s fair dealing foundation.
