Dow Jones and the New York Post have filed a lawsuit against Perplexity in New York, accusing it of copyright and trademark infringement.

The lawsuit accuses Perplexity of fabricating and misattributing news content to established publications.

Perplexity is alleged to have mistakenly added fictional paragraphs to a New York Post article. This poses risks of trademark dilution and misleads readers.

This legal action comes amid similar claims from news outlets like The New York Times, Forbes, and WIRED concerning unauthorized content use.

The New York Times had previously issued a cease-and-desist letter to Perplexity.
