Data show: Korea blockchain patent grant rate is the highest

According to Cointelegraph, data from the London law firm Withers Rogers showed that the Korean blockchain patent grant rate was 54%, ranking first; followed by Japan (17%) and the United States (16%), while China was significantly behind. On the other hand, in China, patent applications must be published before the substantive review, which may be the reason why less than 2% of the Chinese blockchain patents reviewed have been approved.
