During his tenure from 1989 to 1992, he authored several white papers analyzing Delaware revenue sources. Delaware also selected Mr. Clark to submit an economic report and affidavit to the United States Supreme Court in the original jurisdiction case of Delaware v. New York, 507 U.S. 490 (1993).
He entered Georgetown’s law school in 1992 where he earned honors as an articles editor of the Georgetown Law Journal, an Olin Law & Economics Fellow, and a member of the Order of the Coif.

Professor Mark F. Schultz joined the faculty in 2003. He teaches and writes primarily in the area of intellectual property.
Professor Schultz is a frequent author and speaker known for his work on the law and economics of the global intellectual property system. In one of his most influential projects, he worked with the Organization for Economic Cooperation and Development (OECD) to construct a groundbreaking global trade secret protection index (the TSPI). The TSPI is influencing policy discussions on this cutting-edge topic in capitals around the world. Other recent projects have included an empirical study that quantified for the first time the backlogs in patent offices worldwide, a report on how patented innovation is meeting global health challenges, and the construction of a new global index of copyright strength.
Professor Schultz is an influential voice in public policy debates regarding intellectual property. He has testified before the U.S. Congress on copyright law at the invitation of the House Judiciary Committee and has briefed the staff of the U.S. Senate Judiciary Committee on trade secret legislation. He speaks frequently around the world about the connection between secure and effective intellectual property rights and flourishing national economies and individual lives, with invitations from the U.S. Patent and Trademark Office, the U.S. Trade Representative, and the U.S. Copyright Office, as well as numerous academic institutions, think tanks, and industry groups. He served as an NGO delegate to the World Intellectual Property Organization (WIPO) for several years during the WIPO Development Agenda talks. He is also one of the organizers of an ongoing multilateral diplomatic dialogue on best practices in national trade secret laws, and is co-founder of the Center for Protection of Intellectual Property (CPIP) at George Mason University in Washington, D.C.
Among the awards and recognition he has received for his scholarship was the School of Law's Outstanding Scholar of the Year award in 2008. He has been a distinguished visiting scholar at the University of Botswana and a visiting professor at DePaul University College of Law.
Professor Schultz graduated with honors from the George Washington University School of Law. Following law school, he was a judicial clerk for the Hon. Daniel M. Friedman of the United States Court of Appeals for the Federal Circuit in Washington, D.C., and the Hon. Eric G. Bruggink of the United States Court of Federal Claims. Prior to joining academia, he practiced law for a decade, serving as outside general counsel to several tech startups and helping technology companies to expand their businesses and commercialize their intellectual property in dozens of countries. He holds a B.A. in International Economics from George Washington University and has done PhD level coursework in development economics at Southern Illinois University.
He is active in leadership roles in local and national organizations. He has served as chair of the Federalist Society's Intellectual Property Practice Group and the AALS Section on Internet and Computer Law. He is an officer of the American Bar Association's International IP Committee of the International Law Section and the American Intellectual Property Law Association’s Trade Secret Law Committee. He currently is chair of the Academic Advisory Board of the Copyright Alliance.
Professor Schultz teaches Copyright Law, Trade Secret Law, Trademark Law, and a senior seminar on Intellectual Property and Global Development. He established and directs both the Specialization in Intellectual Property Law and the IP Semester in Practice Externship Program. He also co-founded a Legal Globalization Class, offered every other year, that takes students to South Africa and Botswana after spending a semester learning about the legal system, culture, history, and politics of southern Africa. The popular course is a once-in-a-lifetime experience that introduces students to leading lawyers, judges, government officials, and human rights advocates, taking them from Cape Town to Johannesburg to Gaborone as well as many popular destinations including game reserves, national parks, the Cape of Good Hope, and the Cradle of Humankind.
