In 2026, California businesses are seeing a sharp increase in litigation related to the California Invasion of Privacy Act (CIPA), driven primarily by the use of common digital tracking and communication tools. The latest trends focus on how traditional wiretapping laws apply to modern website technologies.

Key litigation trends for 2026 include:

• Website Tracking Class Actions: There is a significant surge in lawsuits targeting businesses that use session replay scripts, pixels (like Facebook Pixel), and analytics software. Plaintiffs argue these tools intercept electronic communications in real time without proper consent.
• Digital Pen Register Claims (Penal Code 631 & 638.51): A major emerging theory involves the “digital pen register” provision. Plaintiffs allege that the collection of IP addresses, keystrokes, and mouse movements constitutes the unlawful recording of routing or signaling information.
• Chat Widget Litigation: Businesses using website chat features are being targeted under Penal Code 631. Claims allege these widgets allow third-party vendors to “read” or intercept messages as they are typed, which is framed as illicit surveillance.
• Stricter Consent Standards: Courts and plaintiffs are moving away from implied consent. In 2026, buried privacy policies or pre-checked cookie boxes are often deemed insufficient. Legal trends indicate a requirement for informed, explicit, and affirmative opt-in consent before any tracking begins.
• High Statutory Damages: Because CIPA allows for statutory damages of $5,000 per violation, these claims are increasingly structured as class actions, creating massive financial exposure for companies with high website traffic.
