California has enacted Senate Bill 690 (SB 690) to block the torrent of demand letters and lawsuits alleging that the nation’s websites have violated a California Invasion of Privacy Act (CIPA) provision covering pen register devices. As SB 690 eliminates one category of claims, recent court decisions are simultaneously raising the pleading burden for the CIPA theories that remain available. Together, these developments may reshape both plaintiff strategy and defense leverage. This article, with insights from litigation parters at Baker Donelson, Duane Morris and Manatt, examines how SB 690 may alter the CIPA litigation landscape; reviews recent court decisions that are drawing clearer lines on standing, consent and class certification; and provides practical guidance for mitigating litigation and regulatory risk.
