News Corp, the parent company of The Wall Street Journal and the New York Post, has filed a lawsuit against the AI startup Perplexity AI, accusing it of illegally copying a large volume of their copyrighted content. The lawsuit claims that Perplexity uses News Corp's articles for its AI-powered search engine without permission, allowing users to bypass original publishers' websites, which diverts revenue from these publishers. News Corp alleges that Perplexity's model, which integrates content from numerous sources to answer user queries, constitutes an abuse of intellectual property rights and harms their business. Despite being notified in July 2024 about the unauthorized use, Perplexity reportedly did not respond, prompting the lawsuit that seeks to stop the AI company from using their content and demands destruction of the database containing their materials. The lawsuit is part of a broader conflict between publishers and tech firms over the unauthorized use of copyrighted material in AI systems. Perplexity has not yet responded to requests for comment.
