On October 22, 2025, the Hon. Jesus G. Bernal, United States District Judge for the Central District of California, denied in full Defendant CoStar Group, Inc.’s motion to dismiss a data privacy class action complaint. The suit alleges that CoStar, a provider of information, analytics, and marketing services to the commercial property industry, violated the pen register provision of California’s Invasion of Privacy Act (“CIPA”) by installing trackers on its websites that surreptitiously collect and share with third parties users’ personal information for targeted advertising purposes. Judge Bernal found that Plaintiffs have standing based on the alleged collection and dissemination of their information, that such conduct falls within the scope of the statute, and that Plaintiffs adequately pled their claims.
