Vintage Ken

“ケン” 日本の商標/”KEN” trade mark right of JAPAN

This story is about Ken’s trademark registration of Japan. In Japan, as of 2nd Augest 2019, one “Ken” trademark rights are registrated.




Shown left is a Japanese trademark right of “Ken”, a part of a public relations issued by Japanese patent office. the appricant was Mattel, requested for registaration on 15th April 1966 and registrated on 7th Mar 1968.

Anyone can see these materials which I introduce here because they have been published for decades.



“Ken ” trademark rights registration in Japan.

application date:15th 1Apr 1966/registration date:7th 7Mar 1968

It seems like Ken was not treated carefully like Barbie in Japan. he was not registered during the time he was “vintage Ken”.

Also-his Japanese trade mark registration is just letters/characters, not a logo.
