On August 28, 2026, the California Legislature passed SB 690, a significant bill aimed at curbing the flood of demand letters and lawsuits asserting “pen register” claims under the California Invasion of Privacy Act (“CIPA”). If enacted, the bill would eliminate the private right of action for website-based pen register claims and could affect many pending lawsuits filed since January 1, 2025.

On July 1, 2026, a California legislative committee advanced amendments to SB 690 that would eliminate private suits asserting website-based “pen register” claims under the California Invasion of Privacy Act (“CIPA”), leaving enforcement exclusively to the California Attorney General.  The amendments come amid a surge of lawsuits and demand letters challenging the use of website technologies under the pen register provision, which the committee described as a “poster child for abusive lawsuits.”  According to the committee analysis, “[b]ecause the potential liability can be staggering,” businesses often settle quickly, thereby “encouraging vexatious litigants to continue blasting out demand letters.”
