Mastering Trademark provides a clear, concise, presentation of the basic principles underlying and the challenges facing modern trademark law in a digital age. This book traces the evolution of trademark from its origin as a common law tort of unfair competition and associated common law trademark rights to the federal Lanham Trademark Act. The book lays a solid foundation covering the basics of obtaining trademark rights, federal trademark registration practice, trademark infringement, defenses, and remedies. It also discusses state and federal laws governing the protection of famous marks under theories of trademark dilution, as well as the growing field of trade dress protection. Mastering Trademark also has extensive coverage of issues relating to trademark use on the Internet covering topics such as domain name disputes, including the Uniform Domain Name Resolution Policy (UDRP), the Anticybersquatting Consumer Protection Act (ACPA), and the use of trademarks by search engines or in key word advertising. The goal of this book is to ground the reader in the law, policies, and theories of trademark law so that the reader can better understand the legal and economic role of trademarks and brands in a modern economy. This book is part of the Carolina Academic Press Mastering Series edited by Russell L. Weaver, University of Louisville School of Law.
