Our patent attorneys, Masahiro Nanjo and Ayako Seta served alongside other attorneys as counsel for the patent holder in the litigation pertaining to the Request for Invalidation Trial against Japanese Patent No. 3,068,858.

In response to the trial decision from the Japan Patent Office rejecting the Request for Invalidation Trial against this patent (Invalidation No. 2011-800018), the Intellectual Property High Court issued a judgment revoking this trial decision (2017 (Gyo-ke) No. 10003, Judgement on November 21, 2017). The Supreme Court subsequently revoked this Intellectual Property High Court judgment and remanded the case back to the Intellectual Property High Court (2018 (Gyo-hi) No. 69, Judgement on August 27, 2019). In this remanded trial, a judgment was issued (2020 (Gyo-ke) No. 10118, Judgement on June 17, 2020) stating that there are no reasons to revoke the trial decision from the Japan Patent Office rejecting the Request for Invalidation Trial against the patent (Invalidation No. 2011-800018).
