This book traces the academic footprint of Hanns Ullrich. Thirty contributions revolve around five central topics of his oeuvre: the European legal order, competition law, intellectual property, the regulation of new technologies, and the global market order. Acknowledging him as a trailblazer, the book aims to capture how deeply Hanns Ullrich has influenced contemporaries and subsequent generations of scholars. The contributors re-iterate the path-breaking patterns of his teachings, such as his contemplation of intellectual property as embedded in competition, the necessity of balancing private and public interests in intellectual property law, the policies of market integration, and the peculiar relationship of technological advancement and protectionism.
