Mapeamento Tecnológico de Patentes em Energia Eólica no Brasil

Abstract

Wind energy diffusion is of great importance to increase the diversity of the Brazilian energy matrix and decrease the country's dependence on hydrological variations. However, little is known about the current state technological development regarding wind technology in the country. Thus, the objective of this article is to analyze the current state of technological development regarding wind energy technology, by patent mapping from the National Institute of Intellectual Property (INPI). Among the main results, we highlight the identification of: i) the low level of Brazilian patenting; ii) the patenting predominance of the Southeast region; iii) the influence of the Brazilian wind generation market to increase the number of patents related to wind generation; iv) the lack of knowledge in some scientific fields, which affects the breadth of wind energy patents developed in the country; v) the low interest of the national power companies in developing R&D activities; and (vi) the reactive behavior of these companies with regard to the development of innovative activities.

how the quality of patents contributes to revitalising the innovation system?, evidence from the renewable energy sector

“…First, R&D activities and patent applications in the renewable energy sector have significantly increased. Second, patent management activities such as valuation are especially crucial for renewable energy diffusion, particularly in Latin-America (Leusin et al, 2018). Finally, climate change brings challenges and opportunities for renewable energy technologies which promote R&D activities, fostering the social use of the patents (Miyamoto & Takeuchi, 2019).…”
