ECONOMIC ANALYSIS OF NETWORK EFFECTS AND INTELLECTUAL PROPERTY Peter S. Menell† ABSTRACT The information revolution has brought demand-side effects to the fore of economic activity, business strategy, and intellectual property jurisprudence and policy. Intellectual property doctrines play a central role in harnessing network effects, promoting innovation to overcome excess inertia, and balancing consumer welfare, competition, and innovation. This Article surveys and integrates the economic, business strategy, and legal literatures relating to network effects and intellectual property. Part I introduces the topic of network effects and provides an overview of the Article. Part II describes the functioning of network markets. Part III examines the interplay of business strategy, contract, standard setting organizations, intellectual property, and competition policy. Part IV presents three principles for tailoring intellectual property regimes and competition policy to network technologies. Part V traces the evolution of intellectual property protection for network features of systems and platforms. Part VI discusses the interplay of intellectual property protection and competition policy. Part VII assesses the extent to which intellectual property protection and competition policy align with the normative design principles. Part VIII identifies promising areas for future research.

INTRODUCTION The economics of intellectual property begins with the classic appropriability problem: In a competitive economy, imitators can enter markets for information goods after inventors and authors have incurred research and development (R&D) costs and sell the innovative or creative product at the cost of reproduction. Without means for appropriating an adequate return on investment in R&D, the market will under-produce technological advances and creative expression.1 The provision of intellectual property protection for technological advances and creative expression affords inventors and authors a mechanism to recoup their investments, although not without imposing the deadweight loss of monopoly exploitation and potentially interfering with cumulative creativity.2 Conventional analysis of intellectual property seeks to optimize the duration and scope of intellectual property rights in order to balance these tradeoffs.3 This framework applies to goods and services for which consumer demand is independent—i.e., where one consumer’s
