INTELLECTUAL PROPERTY MODELS TO ACCELERATE SUSTAINABILITY TRANSITIONS - IPACST Transformations to sustainability rely on innovation with complex diffusion and adoption processes. The role of intellectual property (IP) and IP rights (IPR) in sustainability transitions remains insufficiently understood. IPR can delay transitions by blocking new technologies, but if used effectively can encourage private investments, knowledge sharing and collaborative learning. The project transforms our understanding of how intellectual property (IP) models accelerate sustainability transitions integrating theories and concepts from sustainability, IP and innovation research. To date, sustainability and IP research have been studied independently. This project contributes to the integration of both fields through frameworks that conceptualize (i) which, (ii) how and (iii) under what conditions IP models accelerate sustainable transitions, in connection with sustainable business models. Hence, we build an interdisciplinary research community that furthers our understanding of dynamic sustainable economic development.  An IP model typology, a sustainable business model typology and conceptual frameworks will be developed based upon case studies in clean energy and circular economy in developing and developed countries. With a Delphi study and simulations, the frameworks will be tested for further sectors. To create impact in industries at different levels, we develop and promote tools for selecting suitable IP and business models, best-practice cases and guidelines, awareness and training kits for key stakeholders such as policy makers, funding organizations, businesses and start-up incubators, education institutions and technology transfer offices. The Global Challenges Research Fund (GCRF) supports cutting-edge research to address challenges faced by developing countries. The fund addresses the UN sustainable development goals. It aims to maximise the impact of research and innovation to improve lives and opportunity in the developing world.
