Book excerpt: Although competition law and intellectual property are often interwoven, until this book there has been little guidance on how they work together in practice. As the intersection between the two fields continues to grow worldwide, both in case law and in regulation, the book's markets-based approach, focusing on sectors such as pharmaceuticals, IT, telecoms, energy and agriculture in eleven of the world's most active jurisdictions, provides a much-needed in-depth understanding of how this interplay reveals itself among the different legal systems. Written by a range of authors including judges, regulators, academics, economists and practitioners in both fields, the book provides an international comparative perspective as well as detailed analysis of specific cases, policies and proposals for change. Among the issues and topics covered are the following: – free movement of goods and the protection of intellectual property rights; – standard essential patents & injunction in patent cases; – intellectual property rights between technological development and consumer protection; – geo-blocking; – online platforms and antitrust; – excessive prices. In this context, special attention is paid throughout to the increasing dialogue among Competition Authorities and between Judges and Competition Authorities around the world. As matchless remedy for the lack of uniformity heretofore, the book's investigation of the nexus between competition law and intellectual property in different sectors and in various countries takes a giant step towards a more-balanced approach and more-levelled regulation and practices. It will be warmly appreciated by policy makers, decision makers, regulators, practitioners and academics in both competition law and intellectual property fields
