Book excerpt: Developments and Directions in Intellectual Property Law celebrates the 20th anniversary of award-winning intellectual property (IP) blog, The IPKat, originally founded in 2003. Over the past two decades, The IPKat has covered and commented on several of the most topical developments in the IP field from substantive, practical, and policy standpoints. Today, The IPKat is considered the “Most Popular Intellectual Property Law Blawg” of all time (source: Justia) and its readers are academics, members of the judiciary, policy and law-makers, practitioners, and students from all over the world. By bringing together several of the current and past contributors to The IPKat, this book reflects on the developments and directions that have emerged in the IP field over the past twenty years. Topics covered include changes within substantive IP rights, as well as IP law, policy, and practice broadly intended and from a global perspective. From copyright to trade marks, patents to designs, image and publicity rights to geographical indications, and developments in IP practice and the court system to contract drafting, readers of this book will find expert insights into some of the most notable developments in IP since the inception of The IPKat blog.
