Greg Castanias, head of Jones Day's Federal Circuit team, has over 30 years of experience as a leading appellate and intellectual property litigator. His experience includes five Supreme Court arguments, over 100 Federal Circuit arguments, and countless others in federal and state courts from Alaska to Connecticut. He is a Fellow of the American Academy of Appellate Lawyers and a member of the American Law Institute.
Greg is "a top-tier appellate advocate" who is "fabulous at incorporating and mediating among divergent insights" and "a great team player" (Chambers). "Revered as one of the country's top appellate practitioners for his experience handling matters at the Federal Circuit" (LMG Life Sciences), his experience includes technologies ranging from pharmaceuticals, genetics, and diagnostics to chemistry and electronics, as well as design patent, copyright, trademark, and trade secret disputes.
Twice named a "Trailblazer and Pioneer" in intellectual property law (The National Law Journal), and constantly recognized as an IP and Life Sciences "Star," Greg has been "instrumental in driving the firm's standout appellate practice" (IAM Patent 1000). "A sharp and effective advocate who picks up the details of the matter quickly" and "a great issue-spotter and skilled advocate" (Legal 500), he has "an instinctual feel for the art of persuasion before the Federal Circuit, where he is highly respected" (IAM Patent 1000).
Greg is the lead author of Federal Appellate Practice and Procedure (West Publishing; 3d edition 2023) and is an adjunct professor of law at Indiana University's Maurer School of Law, where he teaches Appellate Practice and Procedure and Federal Circuit Advocacy.
