Abstract
Abstract The article describes the manner in which the Chinese Patent Office set about building up a comprehensive search file following the establishment of the Office in 1980. It was decided that the documentation should satisfy the demands of the PCT minimum documentation and the files were built up with a micture of full text specifications, abstracts and inventories. The basic language of the search file is English and it includes the full text of U.S. patents, EPO documents, PCT pamphlets and Chinese patent applications. The English language abstracts of Japanese applications are included as well as the Japanese language abstracts, and English abstracts of nine countries are held going back for 13 years. The utilization of the search file is emphasized and the existing problems are discussed.
