Database Description

The JAPIO database, provided by the Japan Patent Information Organization, represents the most comprehensive English-language access to Japanese unexamined patent applications (Kokai Tokkyo Koho) published since October 1976. All technologies are covered. Application records include both Japanese and non-Japanese priorities. Abstracts are provided only for applications originating in Japan, but are available for most records. Images of front page drawings, when available for a given patent, are also included.
