The role of patent protection in (clean/green) technology transfer

No 46, MERIT Working Papers from United Nations University - Maastricht Economic and Social Research Institute on Innovation and Technology (MERIT)

Abstract: Global climate change mitigation will require the development and diffusion of a large number and variety of new technologies. How will patent protection affect this process? In this paper we first review the evidence on the role of patents for innovation and international technology transfer in general. The literature suggests that patent protection in a host country encourages technology transfer to that country but that its impact on innovation and development is much more ambiguous. We then discuss the implications of these findings and other technology-specific evidence for the diffusion of climate change-related technologies. We conclude that the "gdouble externality" problem, that is the presence of both environmental and knowledge externalities, implies that IP may not be the ideal and cannot be the only policy instrument to encourage innovation in this area and that the range and variety of green technologies as well as the need for local adaptation of technologies means that patent protection may be neither available nor useful in some settings.
