This publication provides an unparalleled comparative analysis of two "hot topics" in the field of antitrust and unfair competition laws with regard to a number of key countries. The first part of the book examines whether small and middle-sized businesses could or should be subject to specific competition rules. These businesses account for 99% of the enterprises in Europe and the United States, making this a particularly important topic. The papers consider both the public and private enforcement rules across a range of jurisdictions, and a detailed international report, prepared by Michele Carpagnano, identifies general trends and highlights differences and the most interesting features of national regulations. The second part of the book gathers contributions from various jurisdictions on the unfair competition question of whether a company could or should be protected against the use of their trademark, distinctive signs and other components of their image and identity on the part of non-competing companies. The papers focus on the fundamental issue of the competitive relationship as a condition of protection under unfair competition acts, and the connection to intellectual property protection. The comprehensive and insightful international report, prepared by Martine Karsenty-Ricard, brings together these reflections by comparing various national positions.   The book also includes the resolutions passed by the General Assembly of the LIDC following a debate on each of these topics, which include proposed solutions and recommendations. The International League of Competition Law (LIDC) is a long-standing international association that focuses on the interface between competition law and intellectual property law, including unfair competition issues.
