Section III examines the interplay of business strategy, contract, standard setting organizations, intellectual property, and competition policy. Section IV presents three principles for tailoring intellectual property regimes and competition policy for network technologies. Section V traces the evolution of intellectual property protection for network features of systems and platforms. Section VI discusses the interplay of intellectual property protection and competition policy. Section VII assesses the extent to which intellectual property protection and competition policy align with the normative design principles. Section VIII identifies promising areas for future research.
