A Pennsylvania federal court ruled that 11 generic manufacturers, including several subsidiaries of Teva Pharmaceuticals, must answer to a class-action lawsuit claiming they violated state consumer protection and unfair trade practice laws by inflating their prices.

Brought by a plumbers’ union health insurance plan, the lawsuit named a multitude of defendants, including several Actavis companies — all Teva subsidiaries — as well as Apotex and Dr. Reddy’s.

Fifteen companies moved to dismiss the case on the grounds the court lacked jurisdiction.
