Mayor and City Council of Baltimore v. Actelion Pharmaceuticals Ltd., No. 19-2233 (4th Cir. 2021)Annotate this Case
Plaintiffs filed an antitrust class action against Actelion, alleging that Actelion extended its patent monopoly for its branded drug Tracleer — a drug to treat pulmonary artery hypertension — beyond the patent's expiration date. Plaintiffs claimed that Actelion did so "through illegitimate means" with the intent of precluding competition from generic drug manufacturers and charging supracompetitive prices for Tracleer, in violation of federal and state antitrust laws. Plaintiffs further claimed that, as a result of Actelion's illegal monopolization, they were injured by having to pay supracompetitive prices for Tracleer for some three years after Actelion's patent for Tracleer expired.
The Fourth Circuit vacated the district court's limitations ruling and concluded that plaintiffs' antitrust claims did not accrue until they were injured by paying supracompetitive prices for Tracleer after the patent expired in November 2015. Therefore, plaintiffs action commenced in November 2018 was timely. The court also concluded that, even if the February 2014 date, when Actelion entered into agreements settling the generic manufacturers' antitrust claims, marked the last anticompetitive act, damages could not then have been recovered by plaintiffs because their claims would not have been ripe for judicial resolution in view of the speculative nature of future conduct that might have thereafter occurred. Therefore, limitations would not begin to run until the claims became ripe. In any event, the court explained that because plaintiffs alleged that Actelion continued with anticompetitive acts after November 2015 in selling Tracleer at supracompetitive prices, new limitations periods began to run from each sale that caused plaintiffs damages. The court largely agreed with the district court's standing, but concluded that the allegations asserting violations of the laws in states where plaintiffs did not purchase Tracleer may yet be considered when determining whether plaintiffs can, based on a Rule 23 analysis, represent class members who purchased Tracleer in those States, and if they can, then whether plaintiffs can include those claims.
