California Court Lets Privacy Claims Against Wayfair Proceed, Tosses Pen Register Case
California federal court allows CIPA claims against Wayfair to proceed, dismissing pen register claim.
Why it matters: This ruling underscores heightened legal scrutiny of digital surveillance in e-commerce, crucial for legal compliance and privacy enforcement in retail tech.
- On August 15, 2026, the Central District of California allowed CIPA claims against Wayfair to move forward.
- The court dismissed the pen register allegation related to web tracking technologies.
- California federal courts are divided on whether web tracking falls under CIPA’s pen register definition.
- California Senate Bill 690, introduced in 2025, aims to limit private CIPA enforcement related to pen registers in online contexts.
On August 15, 2026, a U.S. District Court in California ruled that legal claims under the California Invasion of Privacy Act (CIPA) against Wayfair could proceed, but dismissed the pen register allegation tied to website tracking technologies. This partial dismissal reflects ongoing judicial debate about the reach of privacy protections in the digital commerce space.
While California state courts have typically dismissed CIPA claims involving pen registers and trap-and-trace devices in the context of online tracking, federal courts remain divided on this issue. According to Holland & Knight, there is no consensus on whether web-based tracking technologies fall within CIPA’s definition of a pen register.
This case against Wayfair adds to the scrutiny of how e-commerce companies use digital surveillance tools, as noted by the National Law Review. The ruling arrives amid legislative developments like California Senate Bill 690, introduced in 2025, which seeks to curb private lawsuits under CIPA related to pen registers and trap-and-trace devices for websites and online apps, aiming to reduce litigation exposure.
This evolving area of law requires companies in retail tech to stay attuned to privacy trends and compliance risks stemming from digital tracking practices.
By the numbers:
- August 15, 2026 — Date of court decision allowing CIPA claims against Wayfair to proceed.
- 2025 — Introduction of California Senate Bill 690 to limit private CIPA enforcement on pen register claims.
Yes, but: The court did not provide detailed reasoning for dismissing the pen register claim while allowing other CIPA claims to proceed, highlighting ongoing legal ambiguities.
What's next: Legislative efforts like SB 690 may soon reshape the scope of private enforcement under CIPA, potentially affecting future litigation.
