Greg Castanias represents clients in appellate and trial courts across the United States — in the United States Supreme Court, courts of appeals, and elsewhere. He heads Jones Day's Federal Circuit practice.
Some of Greg's recent victories as an appellate advocate include Sinochem v. Malaysia Int'l Shipping (2007), a 9-0 Supreme Court win on an important procedural issue affecting international companies in U.S. litigation; Finisar v. DIRECTV (2008), a Federal Circuit reversal of a $129 million patent-infringement judgment; Kyocera Wireless v. International Trade Commission (2008), a pathbreaking Federal Circuit decision limiting the ITC's exclusionary authority; Ball Aerosol v. Limited Brands (2009), a Federal Circuit reversal of a multimillion dollar patent-infringement judgment, as a matter of law; and Martek Biosciences v. Nutrinova (2009), an across-the-board win in a four-patent biotechnology case argued before a rare five-judge Federal Circuit panel. Other recent clients have included Abbott Laboratories, Boston Scientific, Chevron, DePuy Spine, Eastman Chemical, the Estate of James Joyce, Fenwal, Hoffmann-LaRoche, IBM, LabCorp, Martek, The MathWorks, Pfizer, Procter & Gamble, SanDisk, SAP, SiRF, Transocean, and Vizio.
The Legal 500, which evaluates lawyers based on confidential client and practitioner interviews, singled out Greg as one of the United States' leading IP lawyers, calling him "A sharp and effective advocate who picks up the details of the matter quickly," and "a great issue-spotter and skilled advocate." Greg is also the lead author of Federal Appellate Practice and Procedure (West 2008), and he is an adjunct professor of law at the Indiana University Maurer School of Law-Bloomington.
