Robustly representing our clients in IP litigation & conflict in Japan

Our Legal Affairs Section stands ready to provide comprehensive and effective support in cases of IP litigation and conflict in Japan.
Taiyo has represented clients in a number of patent infringement lawsuits, including the "Kiri-Mochi" rice cake patent infringement lawsuit, which received national coverage in Japan.
           In the "Kiri-Mochi" case, we represented the plaintiff, Echigoseika Co., Ltd., against Sato Foods Co., Ltd. In March 2012, the Intellectual Property High Court, overturning the district court's decision, found that Sato had infringed Echigoseika's patent, and awarded Echigoseika damages of JPY800 million (US$7 million). This ruling was established when the Supreme Court subsequently rejected Sato's appeal in September 2012.
