Globalisation is characterised by institutional and political reforms in many countries such as gradual trade liberalisation and international co-ordination of policies. Moreover, globalisation has created centres of power that are alongside, even in competition, with the power of states. Innovation demands extensive up-front R&D costs and strong intellectual property protection is not disconnected from competition principles, but rather, is a vital part of antitrust policy as a whole. Sound intellectual property protection creates the competitive environment required to allow companies to profit from their inventions, which encourages innovation effort. This book covers a gap in literature dealing with both economic and legal aspects of the competition and especially when there is a comparison of US and EU law concerning it. This contains the latest law and case analysis of competition in the US and EU law.
