This chapter studies intellectual property (IP). A hallmark of the New Private Law (NPL) is attentiveness to and appreciation of legal concepts and categories, including the traditional categories of the common law. These categories can sometimes usefully be deployed outside of the traditional common law, to characterize, conceptualize, and critique other bodies of law. For scholars interested in IP, for example, common law categories can be used to describe patent, copyright, trademark, and other fields of IP as more or less “property-like” or “tort-like.” Thischapter investigates both the property- and tort-like features of IP to understand the circumstances under which one set of features tends to dominate and why. It surveys several doctrines within the law of copyright that demonstrate how courts move along the property/tort continuum depending on the nature of the copyrighted work at issue—including, in particular, how well the work’s protected contours are defined. This conceptual navigation is familiar, echoing how common law courts have moved along the property/tort continuum to address disputes over distinctive types of tangible resources.
