In Bristol-Myers Squibb Co. v. Superior Court of California, No. 16-466 (June 19, 2017), the U.S. Supreme Court held that a state court does not generally have specific personal jurisdiction to entertain class-action claims by non-resident plaintiffs against a company headquartered outside of the forum state (here Bristol-Myers Squibb was not based in California). In future class action claims against nationwide corporate defendants, it appears that the U.S. Supreme Court is generally requiring piecemeal litigation in each state where a plaintiff was injured, instead of allowing for a single consolidated class action in a single state court lawsuit.
