Yes / We investigate the relationship between intellectual property rights (IPR) and innovation, for a panel of 48 countries between 1998-2011. Prior empirical studies mainly focus on strength of patent regulations largely ignoring the enforcement of such laws in practice. We employ a new index that accounts for the enforcement related component of the patent system and the Ginarte and Park (1997) index of patent regulatory strength. We thus include two crucial elements of a national patent system, the de jure position relating to book law and IPR regulations, and the de facto position relating to IPR enforcement. We consider nonlinearities between IPR and innovation, and we find that both nonlinearities and the enforcement aspect are significant in explaining the relationship between innovation and IPR systems.

The current patent system is by many scholars considered flawed regarding the intended positiveeffects on innovation, especially for small and medium-sized enterprises (SMEs). However, aneffective patent system requires possibilities for firms to enforce their patent rights to fulfil thebasic premise of inspiring innovation. The purpose of this study is to examine the challenges thatSMEs face in patent litigation and how it affects them and their innovation. 14 semi-structuredinterviews were conducted with Chief executive officers or research and development managersof Swedish SMEs to gain insights into the process of patent litigation and its effects on theinterviewed firms. Results showed that R&D investments decreased after patent infringement inmany cases and that firms had a tendency to change the way new patents are written to createstronger patents. The main finding is that patent litigation had a negative effect on SMEs, due tothe high direct and indirect costs resulting from a patent case. This adds to previous researchwhich highlights the disproportionate effects of patent litigation on small firms compared tolarger firms.

Yes / In this paper we study the determinants of the strength of patent enforcement in 43 member countries of the World Trade Organization (WTO) between 1998 and 2011, a period after the signing of the Trade-Related Aspects of Intellectual Property Rights (TRIPS) agreement. We do so by building on and expanding the seminal work of Ginarte and Park (1997) on the pre-TRIPS determinants of patent rights in the years 1960-1990. We find that in the years after TRIPS was signed, the strength of patent enforcement of a country is positively determined by two variables that signify the usage of the patent and intellectual property system, and the number of patent and trademark applications. We also find that the level of research and development expenditure, the quality of human capital, and the level of development of a country have positive effects on the strength of the enforcement of patent law in practice. Intellectual property rights enforcement is one of the key investment-related policies included in the United Nations Conference on Trade and Development (UNCTAD) Investment Policy Framework for Sustainable Development. Identifying the determinants of strong patent systems will help policymakers at the national and supranational levels to design and implement effective policies that strengthen national patent systems, thereby enhancing economic benefits such as greater levels of commercialization of intangible assets and greater levels of international trade and investment.

No / In this paper we report on a composite index of international patent systems strength for 48 developing and industrialized countries annually from 1998 to 2011. Building upon earlier indices we develop a conceptual framework informed by transaction cost theory and derive measures which emphasize the importance of enforcement-related aspects of the patent system of countries. Findings reveal harmonization of the regulative aspects of patent protection internationally in the post-TRIPs era but not of overall national patent systems. The index should inform studies on the relationship between national patent systems and a range of international business and other phenomena. (C) 2013 Elsevier Inc. All rights reserved.
