description

Case Summary

Taiho Pharmaceutical Co. and its co-plaintiffs brought a patent infringement action against MSN Laboratories Private Ltd. and related defendants under docket 21-cv-00838. The case appears to be a Hatch-Waxman dispute, the standard vehicle for brand pharmaceutical companies challenging generic drug applications before FDA approval. The docket reflects a Stipulation of Dismissal at entry 164, signaling the parties reached a resolution — likely a settlement or licensing agreement — without a final judgment on the merits. The terms of any such agreement are not reflected in the available record.
