Japanese companies accounted for 48.6% of global patent applications related to all-solid-state batteries, according to the Japan Patent Office. The technology is expected to dramatically increase the range of electric vehicles.
The patent office’s analysis of applications filed by companies and individuals in multiple countries and regions shows that Japan was well represented in applications for cutting-edge technology. Japan ranks third among all countries and regions in applications for quantum computing-related technologies.
All-solid-state batteries, which have higher capacity and are easier to compact, are considered next-generation batteries.
From 2013 to 2021, a total of 5,438 patent applications have been filed for the batteries worldwide, with Japan accounting for 48.6%, or 2,645 applications.
By company, Panasonic Holdings Corp. topped the list with 475 applications, followed by Toyota Motor Corp. with 405 requests.
South Korea’s Samsung Group and LG Group ranked third and fourth respectively, while Fujifilm Holdings Corp. took fifth place with 164 registrations, followed by Murata Manufacturing Co. with 154 registrations. Of the twenty largest companies, fourteen were Japanese.
