What are the implications of a federal district court's order certifying a class of up to 250 million class members in an antitrust multi-district litigation?

Qualcomm Incorporated seeks interlocutory review of the district court's order certifying a nationwide class of up to 250 million class members in an antitrust multi-district litigation raising claims under the Sherman Act and California state law. Because the district court erred in its choice of law analysis and in light of FTC v. Qualcomm Inc., 969 F.3d 974 (9th Cir. 2020), we vacate the class certification order. On remand, the district court should reconsider the viability of Plaintiffs' claims given FTC v. Qualcomm.
