This collection of essays, by leading scholars and practitioners from a range of countries, pays homage to a pre-eminent figure in the field of intellectual property: Sam Ricketson. Inspired by the breadth of Ricketson’s work, the contributions explore issues from a perspective that looks across the field – in particular, across the regimes, jurisdictions, disciplines and professions of IP. Topics explored across the regimes include the nature of IP subject matter, overlaps in protection, historical connections between copyright and patents and the transplantation of civil law moral rights to common law copyright. In across jurisdictions, chapters address, inter alia, the application of private international law to cross-border IP disputes, the Berne Convention and AI-authored works, how countries might exit the Berne Convention and dispute settlement under TRIPS. The intersection of copyright and privacy laws, the relationship between privacy, personality and trade mark laws, the teaching of IP and human rights and the conduct of empirical and historical research in IP are among the matters considered across disciplines. Contributions across professions include the participation of scholars in IP policy making, the IP textbook in legal practice, and the role of expert evidence in IP litigation.
