  • A new lawsuit against Perplexity AI claims responses generated by the artificial intelligence platform violate the trademarks of Encyclopaedia Britannica and Merriam-Webster by attributing false information to their widely esteemed brands. The complaint alleges Perplexity’s generative AI “answer engine” violates the plaintiffs’ copyrights and also cites them as sources of false or incomplete information.

  • In August, the Federal Circuit issued a surprisingly self-critical ruling in the long-standing dispute between Erik Brunetti and the USPTO over Brunetti’s efforts to register the term F*CK for a wide variety of goods and services. The Federal Circuit concluded that the Board’s decision in In re Brunett lacked sufficient clarity and therefore vacated it for further proceedings, which although facially unremarkable, may not only prove to be a boon to Brunetti, it may also be highly beneficial to many trademark owners who have been forced to wrestle with failure-to-function refusals.

  • A federal judge in the Northern District of California granted preliminary approval on September 25 to a $1.5 billion settlement between Anthropic and a class of authors who alleged that the artificial intelligence company used their copyrighted works to train its chatbot Claude without their consent. The settlement is the largest copyright settlement of all time, covering 482,460 works and paying authors slightly more than $3,000 per work infringed.

  • Many companies have been participating in the growing trend of challenging counterfeit products of their goods by filing “Schedule A” lawsuits. These suits are mass actions typically alleging intellectual property infringement and they allow plaintiffs to sue many defendants at once, with the defendants’ names grouped in a “Schedule A” appendix attached to the complaint.
