How This List Is Built
Each entry is a defendant that faces hundreds or thousands of federal civil cases of the same case type — the signature of a mass tort, a multidistrict litigation, or a coordinated filing wave. The list is computed directly from the docket data with no editorial selection, and refreshes with each data update. Click through to a defendant for the full analytics: filing trends, courts, opposing parties, and every underlying case.
