Yomiuri Shimbun, Japan's largest daily newspaper, has filed a lawsuit worth over 20 billion yen (approximately 20 billion KRW) against the generative artificial intelligence (AI) company Perplexity, alleging unauthorized use of more than 100,000 of its articles. This is the first time a major Japanese media outlet has filed a lawsuit over copyright infringement by generative AI.
On August 7, NHK reported, "The Yomiuri Shimbun Group has filed a lawsuit with the Tokyo District Court against Perplexity, claiming unauthorized use of its articles and seeking both a suspension of article use and damages of over 2.1 billion yen (approximately 20 billion KRW)."
According to Yomiuri Shimbun, Perplexity, which provides a search service using generative AI, has been reproducing and using Yomiuri Shimbun's articles and photos without permission to provide answers to users. The number of articles used without authorization reached approximately 120,000 between February and June of this year.
The Yomiuri Shimbun Group stated, "If such 'free-riding' is tolerated, it could negatively impact accurate reporting based on journalistic investigation, and may undermine the foundations of democracy."
