In a landmark ruling, on September 25, 2023, a federal judge in Delaware denied summary judgment over a legal research software companies use of copyrighted material to train its artifical intelligence database.  The federal court ruled that it will be up to a jury to decide whether Ross Intelligence infringed Thomson Reuters’ copyrights by copying material from its legal research platform, Westlaw. The case has been closely watched by legal experts, as it could set a precedent for how copyright law applies to artificial intelligence (AI).
