At last, the Trade Mark Act 2014 amendment, which will come into effect on April 1 2015, has introduced new kinds of trade marks such as colour marks and sound marks. In the United States, Christian Louboutin had filed a lawsuit against Yves Saint Laurent for an infringement of Louboutin's trade mark, consisting of a red, lacquered outsole on a high fashion woman's shoe. We may expect similar lawsuits in Japan in the near future.
