A data set of Japanese corporates’ green transformation technologies patents

Abstract

Abstract* In 2020, the Government of Japan declared 2050 “carbon neutral” and launched a long-term strategy to create a “virtuous cycle of economy and environment.” Japanese corporations possess many technologies that contribute to decarbonization, which is important for expanding investments in green transformation technology inventory (GXTI) development. Patent data are the most reliable measure of business performance for applied research and development activities when investigating knowledge domains or technological evolution. Our paper describes a Japanese patent dataset of Japanese corporations’ green transformation (GX) patent applications on the Japan Platform for Patent Information, using a search method of bombinating International Patent Classification (IPC) codes and keywords. The dataset contains 37,476 GX patent applications from 298 corporations during the period 1999–2022.
