This widely used casebook, cited by the Supreme Court in its Moseley v. V Secret Catalogue decision on trademark dilution, is authored by three of the nation's preeminent trademark practitioners and teachers. Constitutional issues—pertaining to the Commerce Clause, the Patent and Copyright Clause, the Supremacy Clause, and the First Amendment—are reshaping modern trademark law, have been outcome-determinative in many high-profile cases, and are fueling extremely influential debates in academic literature. Throughout the casebook, great attention is paid to the constitutional and practical relationship of trademark law with other areas of intellectual property law.

The casebook provides an in-depth presentation and analysis of the principal questions and problems in trademark law today, and a synthesis of the current and developing law. The organization provides students with a foundation in the historical and normative principles that have been governed and continue to govern trademark law's evolution, before progressively exposing them to more sophisticated and specific problems. Each section begins with an introductory overview followed by tightly edited cases and a summary of the issues, with analysis through notes and other secondary textual materials.
