Abstract

Debates over intellectual property's justifications tend to treat natural rights and utilitarian accounts as competitors, but they should be seen as complements instead. Lockean and Kantian theories of intellectual property highlight the strong interests that intellectual property creators have in profiting from and exercising some degree of control over their work, but neither theory gives sufficient justification for the full assortment of rights that intellectual property owners have under current law. Utilitarian accounts provide an essential supplement to these natural rights theories by focusing on society's interests in the production of useful information and creative expression, but that does not mean intellectual property law should single-mindedly strive only to maximize social welfare. Developing both natural rights-based and utilitarian justifications, this dissertation advances a pluralist account of intellectual property that understands different features of copyright, patent, and trademark law to be serving different normative interests
