More than 50 percent of U.S. exports now depend on some form of intellectual property protection. This course provides an overview of the substantive content of, and legal authority for, international IP rights, drawing on cases, treaties and materials in copyright, patent and trademark law. We will examine international and comparative law issues of major importance to modern IP practice, including obligations for IP protection arising under international public law, the emerging role of transnational private law in the acquisition and enforcement of IP rights, and the geopolitics of IP trade and harmonization.
