The research of patent information retrieval system in Japan was started in 1960's by the Patent Office's examination mechanization laboratory. In 1971, Japan Patent Information Center (Japatic) was established, and the free keyword patent search system was developed for public services. By mounting this system into the online system, PATOLIS was born in 1978 and rapidly spread. The PATOLIS was succeeded by Japan Patent Information Organization (Japio) in 1985 and monopolized online patent information services. However, the PATOLIS monopoly is in decline owing to participation of private enterprises to online service business caused by the publication of CD-ROM of patent applications in 1993 and the advent of free service of the Patent Office's Industrial Property Digital Library (IPDL) in 1999.
