Abstract: On 1 January 1994, China acceded to the PCT; the Chinese Patent Office became a Receiving Office (RO) and, simultaneously, became an International Searching Authority and an International Preliminary Examining Authority (IPEA) appointed by the PCT Union. At the same time, Chinese became a working language of the PCT. By the end of September 1995, the CPO had received a total of 183 PCT applications. In order to set up the necessary search files in a very short time for the examiners performing the international search, the CPO took a new way of establishing the PCT search files according to the examiner's needs.
