MATT O’BRIEN, AP; Reddit sues AI company Perplexity and others for ‘industrial-scale’ scraping of user comments

"Social media platform Reddit sued the artificial intelligence company Perplexity AI and three other entities on Wednesday, alleging their involvement in an “industrial-scale, unlawful” economy to “scrape” the comments of millions of Reddit users for commercial gain.

Reddit’s lawsuit in a New York federal court takes aim at San Francisco-based Perplexity, maker of an AI chatbot and “answer engine” that competes with Google, ChatGPT and others in online search. 

Also named in the lawsuit are Lithuanian data-scraping company Oxylabs UAB, a web domain called AWMProxy that Reddit describes as a “former Russian botnet,” and Texas-based startup SerpApi, which lists Perplexity as a customer on its website.

It’s the second such lawsuit from Reddit since it sued another major AI company, Anthropic, in June.

But the lawsuit filed Wednesday is different in the way that it confronts not just an AI company but the lesser-known services the AI industry relies on to acquire online writings needed to train AI chatbots."

Perplexity's definition of copyright gets it sued by the dictionary; Engadget, September 11, 2025

 Anna Washenko, Engadget; Perplexity's definition of copyright gets it sued by the dictionary

"Merriam-Webster and its parent company Encyclopedia Britannica are the latest to take on AI in court. The plaintiffs have sued Perplexity, claiming that AI company's "answer engine" product unlawfully copies their copyrighted materials. They are also alleging copyright infringement for instances where Perplexity's AI creates false or inaccurate hallucinations that it then wrongly attributes to Britannica or Merriam-Webster. The complaint, filed in New York federal court, is seeking unspecified monetary damages and an order that blocks Perplexity from misusing their content."

Japan’s largest newspaper, Yomiuri Shimbun, sues AI startup Perplexity for copyright violations; NiemanLab, August 11, 2025

ANDREW DECK  , NiemanLab; Japan’s largest newspaper, Yomiuri Shimbun, sues AI startup Perplexity for copyright violations

"The Yomiuri Shimbun, Japan’s largest newspaper by circulation, has sued the generative AI startup Perplexity for copyright infringement. The lawsuit, filed in Tokyo District Court on August 7, marks the first copyright challenge by a major Japanese news publisher against an AI company.

The filing claims that Perplexity accessed 119,467 articles on Yomiuri’s site between February and June of this year, based on an analysis of its company server logs. Yomiuri alleges the scraping has been used by Perplexity to reproduce the newspaper’s copyrighted articles in responses to user queries without authorization.

In particular, the suit claims Perplexity has violated its “right of reproduction” and its “right to transmit to the public,” two tenets of Japanese law that give copyright holders control over the copying and distribution of their work. The suit seeks nearly $15 million in damages and demands that Perplexity stop reproducing its articles...

Japan’s copyright law allows AI developers to train models on copyrighted material without permission. This leeway is a direct result of a 2018 amendment to Japan’s Copyright Act, meant to encourage AI developmentin the country’s tech sector. The law does not, however, allow for wholesale reproduction of those works, or for AI developers to distribute copies in a way that will “unreasonably prejudice the interests of the copyright owner."

"Dow Jones, the parent company to the Wall Street Journal, and the New York Post filed a lawsuit Monday against artificial intelligence company Perplexity, alleging that the company is illegally using copyrighted work.

The suit alleges that Perplexity, which is an AI research and conversational search engine, draws on articles and other copyrighted content from the publishers to feed into its product and then repackages the content in its responses, or sometimes uses the content verbatim, without linking back to the articles. The engine can also be used to display several paragraphs or entire articles, when asked."
