The Ninth Circuit Court of Appeals has ruled in favor of Accident Law Group, a personal injury law firm based in Arizona, rejecting trademark infringement claims made by rival firm Lerner & Rowe. The lawsuit stemmed from Lerner & Rowe's accusations that Accident Law Group was improperly using Google Ads linked to Lerner & Rowe's search terms, potentially diverting clients. The court's decision upholds a previous ruling from an Arizona federal court, affirming that the use of competitive keyword advertising does not constitute trademark infringement. This ruling aligns with broader trends in trademark law regarding competitive advertising practices.
