Book excerpt: This book challenges the philosophical foundations of current trademark systems in the USA and the UK. It argues that the process of trademark creation should be transformed to the more practical and realistic proposition of “co-authorship” of trademarks by both the public and trademark owners. The book develops the “Economic-Social Planning justification”, which departs from the economic argument that trademarks reduce consumer search costs, and then proposes that trademarks should be formulated in a manner which helps foster a just and attractive culture. Trademarks are thus seen as source and origin identifiers, rather than quality identifiers. The book focuses on the often ignored role of the public and their rights in trademarks and calls for the adoption of the confusion rationale for trademark protection, not the dilution individualistic rationale. The two jurisdictions of this book prove adverse effects over the rights of the public in terms of using trademarks in cultural and expressive contexts, thereby threatening the principles of freedom of expression as a human fundamental right.
