Economic development increasingly depends to a large extent on innovation. Innovation is generally covered by intellectual property (IP) rights and usually requires extensive funding. This book focuses on IP and debt financing as a tool to meet this demand. This book clarifies the situation of the use of IP as collateral in practice through a survey conducted in Japan on IP and debt financing. IP and debt on a global scale, either by attracting foreign lenders or by collateralizing foreign IP rights, needs appropriate private international laws. This book analyzes such regulations in which the United Nations Commission on International Trade Law (UNCITRAL) has worked, paying due attention to the law of finance and insolvency law, as well as IP laws. However, further analysis is needed to identify under what conditions such solutions would show optimal effects. This book offers functional analysis from an economic point of view.
