  The United States holds the highest share of patent applications from Japanese applicants to foreign countries,while Europe holds the highest share of the different regions in the world (Figure2-3-10(1)) .

  In the same way,the United States accounted for the largest share of patents granted to Japanese in foreign countries,followed in order by South Korea,Germany,the United Kingdom,and France. While patents granted overseas tended to be concentrated in the major advanced nations,the number granted in South Korea has risen sharply in recent years (Figure2-3-10(2)) .

  For the share of patent applications and patents granted held by Japanese in major countries,the numbers in South Korea were fairly high for some years but have recently been declining.The United States registered the highest proportion of Japanese patent applications and patents granted (Table2-3-11) .
