A California federal court has ruled on Wayfair’s attempt to dismiss a lawsuit alleging that its website used third-party tracking pixels to collect information about visitors and share that information with outside companies. In Limas v. Wayfair LLC, the court rejected most of Wayfair’s arguments at the pleading stage but dismissed the plaintiff’s claim under California’s pen-register statute after the plaintiff failed to respond to Wayfair’s challenge to that claim.
The August 13, 2026 decision involved allegations concerning tracking technologies connected with social media and advertising platforms. The ruling did not determine that Wayfair unlawfully tracked website visitors. Instead, it addressed whether the allegations were sufficient to allow the plaintiff’s claims to continue beyond the motion-to-dismiss stage.
Case Background: Alleged Tracking on Wayfair.com
Joseph Limas brought the lawsuit after visiting Wayfair.com to browse products. According to the complaint, Wayfair’s website allegedly deployed tracking pixels associated with several third parties, including TikTok, Meta, Pinterest, Snapchat, X, and Reddit.
The complaint alleged that these tracking technologies collected information about the pages and products viewed by visitors, connected browsing activity with social media accounts, and transmitted information to third parties for advertising-related purposes.
Limas asserted claims under the California Invasion of Privacy Act (CIPA), including Section 631(a) and Section 638.51.
In Limas v. Wayfair LLC, No. CV 25-11185-DMG (Ex), 2026 WL 2351592 (C.D. Cal. Aug. 13, 2026), Chief Judge Dolly M. Gee considered Wayfair’s motion to dismiss the First Amended Complaint.
Court Rejects Several Arguments for Dismissal
Encryption Did Not Automatically Defeat the CIPA Claim
One of Wayfair’s arguments concerned the use of encryption. Wayfair contended that encrypted communications should not be considered the “same” communications for purposes of CIPA Section 631(a). It also argued that the alleged interception did not take place while the communications were in transit.
The court rejected that interpretation.
In examining the statutory language, the court treated the relevant reference as referring back to the previously identified message, report, or communication. The court did not interpret the statute as requiring information to remain in precisely the same form throughout the transmission process.
Accordingly, the presence of encryption did not, by itself, defeat the plaintiff’s Section 631(a) allegations at the pleading stage.
Complaint Provided Enough Detail About the Tracking Technologies
Wayfair also argued that the plaintiff had failed to provide sufficient information about the specific searches he conducted or the precise information that was allegedly returned to him.
The court disagreed that the allegations were too vague to proceed.
The complaint identified the tracking technologies at issue, provided examples involving website pages and code, and described the types of information that the technologies allegedly collected.
At the motion-to-dismiss stage, the court found those allegations sufficiently detailed to allow the claims to continue.
Snapchat Allegations Received Separate Treatment
The court separately considered allegations involving Snapchat.
The ruling recognized that an IP address, standing alone, does not carry a reasonable expectation of privacy under applicable Ninth Circuit precedent.
However, the plaintiff’s allegations concerning the Snapchat tracking technology went beyond the collection of an IP address.
According to the complaint, the Snapchat tool allegedly tracked products viewed by users, followed users across multiple devices, and matched browsing information with data that Snapchat already possessed.
Because the allegations went beyond simple IP-address collection, the court allowed the Snapchat-related claim to proceed at that stage of the litigation.
Wayfair Was Not Entitled to the Service-Provider Exemption
Wayfair also argued that it qualified for CIPA’s service-provider exemption because it operated a website and therefore should be considered a provider of electronic or wire communication services.
The court rejected that argument.
Operating an online retail website, the court reasoned, does not automatically transform a company into a provider of electronic or wire communication services for purposes of the statutory exemption.
The court also concluded that Wayfair had not adequately explained how its alleged advertising-related use of tracking pixels fit within the specific purposes listed in the statute for the exemption.
As a result, Wayfair’s service-provider argument did not provide a basis for dismissing the claims at the pleading stage.
First Amendment and Other Legal Arguments Also Failed
Wayfair raised additional arguments based on the rule of lenity, the canon against absurd results, and the First Amendment.
The court rejected those arguments as grounds for dismissal.
Regarding the First Amendment, Wayfair argued that the alleged duplicated transmissions constituted its own protected expression.
The court did not accept that characterization. It reasoned that the communications at issue were the user’s communications and that the mere installation of software did not, by itself, constitute protected expression by Wayfair.
These rulings allowed the relevant claims to survive the motion-to-dismiss stage without deciding whether the underlying allegations would ultimately be proven.
Pen-Register Claim Dismissed After Plaintiff Failed to Respond
The court did dismiss Limas’s claim under CIPA Section 638.51, but the reason for that dismissal is particularly significant.
The dismissal was not based on a substantive determination that the tracking technologies could never qualify as pen registers.
Instead, Wayfair had challenged the Section 638.51 pen-register claim in its motion to dismiss, and Limas’s opposition brief did not respond to that particular argument.
The court treated the plaintiff’s failure to address the argument as a waiver and dismissed the pen-register claim on the grounds raised by Wayfair.
The dismissal was without leave to amend.
The court nevertheless distinguished that claim from the trap-and-trace theory asserted under the same statutory section. The trap-and-trace claim was allowed to proceed.
Thus, the ruling did not resolve every issue involving CIPA Section 638.51. It dismissed the pen-register theory after the plaintiff failed to defend it while allowing the separate trap-and-trace theory to continue.
What the Wayfair Ruling Means for Website Tracking Litigation
The decision demonstrates how both the underlying legal theory and the parties’ briefing can influence the outcome of a motion to dismiss.
For website operators, the ruling does not establish a general exemption for tracking pixels, advertising technologies, or other third-party tracking tools.
The court rejected Wayfair’s broader service-provider argument and permitted several allegations involving website tracking to move forward.
For plaintiffs bringing CIPA website-tracking claims, the decision also illustrates the importance of responding directly to every argument raised in a motion to dismiss.
Here, the pen-register claim was dismissed because the plaintiff failed to address Wayfair’s challenge in the opposition brief. The court therefore treated the argument as waived rather than independently resolving the underlying legal question in the plaintiff’s favor or against the broader use of tracking technology.
The claims that survived the ruling can continue beyond the motion-to-dismiss stage. That does not mean the plaintiff has established liability. The remaining allegations still must be proven or otherwise resolved through subsequent litigation.
