Sandra K. Law

Sandra K. Law is a Member at Schrader, Companion, Duff & Law, PLLC, where she practices as local counsel for patent litigation, alongside her primary focus on general civil litigation, labor and employment, and workers' compensation matters. Her firm, established in 1925, handles various civil litigation, including patent cases in state and federal courts in West Virginia, Ohio, and Pennsylvania.

In patent litigation, Ms. Law has experience representing defendants. Her tracked appearances include serving as local counsel for Celltrion, Inc. in the significant biosimilar dispute, Regeneron Pharmaceuticals, Inc. v. Celltrion, Inc. This case involved a multi-patent infringement action concerning Regeneron's EYLEA® (aflibercept), a blockbuster anti-VEGF therapy, which asserted 38 patents (and a separate suit involving 25 patents). The litigation concluded with a confidential settlement allowing Celltrion to launch its biosimilar in the U.S. in late 2026, leading to the dismissal of all related intellectual property litigation. The Federal Circuit also affirmed a preliminary injunction against Celltrion in a related appeal.

Information regarding her regular appearance in PTAB or IPR proceedings is not reliably available from public sources.

Ms. Law earned her B.A., summa cum laude, from Bethany College in 1985 and her J.D. from Duquesne University in 1992. She is admitted to practice in West Virginia and Pennsylvania, as well as before the U.S. District Courts for the Northern and Southern Districts of West Virginia and the Western District of Pennsylvania, and the U.S. Courts of Appeals for the Third and Fourth Circuits.
