In this thought-provoking analysis, the author takes three examples of emerging markets (Brazil, India, and Nigeria) and tells their stories of pharmaceutical patent law-making. Adopting historiographical and socio-legal approaches, focus is drawn to the role of history, social networks and how relationships between a variety of actors shape the framing of, and subsequently the responses to, national implementation of international patent law. In doing so, the book reveals why the experience of Nigeria - a country active in opposing the inclusion of IP to the WTO framework during the Uruguay Rounds - is so different from that of Brazil and India. This book makes an original and useful contribution to the further understanding of how both states and non-state actors conceptualise, establish and interpret pharmaceutical patents law, and its domestic implications on medicines access, public health and development.
