Stealing data: Ninth Circuit examines whether cellular data can be subject to a conversion claim

Plaintiffs sued Google alleging Google improperly used plaintiffs’ cellular data without consent, constituting conversion under California law. The lower court dismissed the case for failure to state a claim. Plaintiffs sought review with the Ninth Circuit. On appeal, the court reversed the lower court’s decision concerning the conversion claim, finding that cellular data is something that can be subject to conversion.

The court observed that a successful conversion plaintiff must plead and prove (1) ownership or rightful possession of property, (2) defendant’s use of the property in violation of plaintiff’s rights, and (3) resulting damages. The court found that plaintiffs satisfactorily established cellular data as a form of personal property subject to conversion, given its definable nature, potential for exclusive control, and plaintiffs’ legitimate expectations based on their data plans.

Moreover, the court concluded that plaintiffs’ allegations against Google meet the criteria for conversion, demonstrating unauthorized use of their cellular data that went against their property interests and resulted in quantifiable damages. By equating Google’s actions to a “forced sale” of plaintiffs’ data, the court underscored the tangible impact of intangible property loss.
