FujiFilm Corporation. Japanese Intellectual Property High Court Case No. 2016(Gyo-Ke)10092. Decided 25 October 2017.

  • “Dispersion Composition, Cosmetic Preparation for Skin Care Use, and Dispersion Composition Manufacturing Method” case
  • DHC Corporation v. FujiFilm Corporation
  • Japanese Intellectual Property High Court Case No. 2016(Gyo-Ke)10092
  • Decided 25 October 2017

In this judicial appeal from DHC’s failed attempt to invalidate FujiFilm’s patent before the Japan Patent Office (JPO), the Japanese Intellectual Property High Court upholds the decision of the JPO Trial and Appeal Division, finding none of the arguments advanced by DHC urging invalidation of FujiFilm’s patent persuasive. In affirming the inventive step of FujiFilm’s patent, the Court found that a website disclosure at issue in the present case did not constitute the making available to the public of all features of the invention via an electronic communication line prior to the application filing date; that even if adjustment of pH might be considered routine knowledge in the context of a skin care cosmetic it would not have been obvious to apply such knowledge to an emulsion composition in a nonpatent disclosure at issue in the present case; and it would not be proper to infer a date of distribution from a date of publication of, or a date of manufacture disclosed in, a nonpatent disclosure at issue in the present case.
