BLB&G Associate Prachi Patel and Matthew Arrow explore the evolving interpretation of California's privacy law in an article featured in the American Bar Association's online newsletter. The authors examine the California Invasion of Privacy Act’s (“CIPA”) Pen Register Provision and how federal courts are addressing its application to internet-based tracking technologies. They highlight key cases, including Greenley v. Kochava, where courts have redefined “pen registers” to include software that collects user data, emphasizing the statute’s broad and adaptable language. They conclude by noting that courts are largely rejecting defendants’ attempts to limit the law’s reach, signaling a shift toward recognizing modern tracking technologies as privacy intrusions under CIPA.
