Robert Greenspoon

Partner, Dunlap Bennett & Ludwig

Robert Greenspoon is a partner of Dunlap Bennett & Ludwig. He is a registered patent attorney who concentrates his practice in the litigation, trial and appeal of patent and other complex cases. Rare among lawyers, his practice spans every aspect of the patent field. He works with inventors to file new patent applications, defends those inventions in all types of Patent Office proceedings (including PTAB challenges), tries patent cases in the courts, argues for appellants and appellees in patent appeals at the United States Court of Appeals for the Federal Circuit, and brings and defends patent proceedings at the United States Supreme Court.

Mr. Greenspoon has argued numerous cases before the Courts of Appeals for the Fourth, Eighth and Federal Circuits. Since co-founding the Firm, he argued the winning appeals in D’Agostino v. MasterCard Int’l Inc., 844 F.3d 945 (Fed. Cir. 2016), Medtronic v. LifePort Sciences (Federal Circuit, Appeal No. 15-1862, 2016), Computer Software Protection v. Adobe Systems, Inc. (Federal Circuit, Appeal No. 15-1608, 2016), Zayed v. Associated Bank, 779 F.3d 727 (8th Cir. 2015), 1st Media, LLC v. Electronic Arts, Inc., et. al., 694 F.3d 1367 (Fed. Cir. 2012), HyperPhrase v. Google (Federal Circuit, Appeal No. 2007-1125, 2007), and 1st Technology v. Bodog (Federal Circuit, Appeal No. 2008-1132, 2008). At his first appellate argument, he became possibly the youngest attorney to argue successfully for a patentee-appellant in a multimillion-dollar patent case, IMS Technology, Inc. v. Haas Automation, Inc., 206 F.3d 1422 (Fed. Cir. 2000).

Mr. Greenspoon began his law career serving as a judicial law clerk to the Honorable Brian Barnett Duff of the United States District Court for the Northern District of Illinois. He co-authored “Are Patent Trolls Really Undermining the Patent System?” in the September/October 2006 issue of IP Litigator, “Obviousness after KSR v. Teleflex: A Private Practice Perspective,” in the August/September 2007 issue of Intellectual Asset Management Magazine, reprinted in the July/August 2007 issue of IP Litigator, and authored “Is the United States Finally Ready for a Patent Small Claims Court?” in the Winter 2009 volume of the Minnesota Journal of Law, Science and Technology. The Columbia Science and Technology Law Review published his co-authored article “Don’t Assume a Can Opener: Confronting Patent Economic Theory with Licensing and Enforcement Reality” in June 2011. Mr. Greenspoon continues regularly writing on patent policy.
