This book identifies and addresses the key principles and policies with regard to the protection of intellectual property in the United States. A select group of highly-regarded contributors illustrate several themes which are recurrent in the many debates concerning US law and policy on intellectual property. The need for a constant expansion of protectable subject matter is critically analyzed, especially in relation to trade mark and patent laws. The chapters within the book discuss a question of critical jurisprudential importance: have the legislature and the judiciary taken sufficient consideration of the different economic and constitutional rationales of intellectual property protection when extending the scope of intellectual property protection? A tentative agenda as to the future direction for both Congress and the courts to adopt, in light of the new technological changes which have affected all areas of intellectual property protection equally, is also suggested. Policymakers will find this book of great interest as will academics and students of intellectual property law and international law.
