The Trademarks and Unfair Competition Deskbook, Sixth Edition provides practitioners of trademark and unfair competition law an organized guide to the decisions, legislation, treatises, and commentary, a delineation of the principal questions and problems to be expected, and an up-to-date synthesis of the current and developing law. E-commerce and the Internet have sparked phenomenal growth in recent years in the scope and significance of trademark and unfair competition law. New challenges arise daily as the law responds to new technologies and more sophisticated forms of communication. Law schools, law firms, corporate legal departments, and entrepreneurs across the United States and abroad have expanded their intellectual property resources. This growth has resulted in intense intellectual ferment within academia, the courts and the practicing bar. Like patent and copyright law, trademark and unfair competition law are in a state of rapid evolution. Many previously unquestioned principles are now being rethought, foundational changes in the policy rationales and the doctrinal and constitutional dimensions of this ancient body of law are being considered and implemented, false leads are being weeded out (or, sometimes, newly introduced). E-commerce and technological developments have raised new questions about the relationship of trademark law to other bodies of intellectual property law. The U.S. Supreme Court's selection of cases to be heard reflects these trends, and the recent decisions of that court are featured in this Trademarks and Unfair Competition Deskbook, Sixth Edition.
