The Federal Circuit's May 6, 2025 decision in Jazz Pharmaceuticals v. Avadel focuses on the scope of injunctive relief for infringement under 271(e). The appellate court held that a district court may not enjoin a pharmaceutical company from initiating new clinical trials or offering open-label extensions where such activities are protected by the Hatch-Waxman Act's safe harbor provision, even when the company's commercial product has been found to infringe a valid patent. The court reversed the portions of the injunction that would have prohibited these activities, and vacated and remanded the portion that barred seeking FDA approval for new indications.
