 Statistics and analysis of relevant citations in international search reports in the CPOLingling Cao World Patent Information, 1996, vol. 18, issue 4, 215-217 Abstract: Since China acceded to the PCT in 1994, the Chinese Patent Office has been establishing examination search files to meet the requirements of the PCT minimum documentation. In order to have a basis for future work, this paper gives statistics and analysis by categories of the relevant documents cited in 159 PCT international search reports which the CPO finished in 1994 and 1995, including countries, number of documents and technical fields. The conclusions are as follows: 1. (1) the technical fields of the majority of Chinese patents seeking protection outside China in 1994 and 1995 claimed medical apparatus and instruments, and health care medicines;2. (2) at present, the starting year for search files should be fixed temporarily at 1920;3. (3) in PCT international search reports made in the CPO, US patents were cited most often, followed by Chinese documents, then European documents. Japanese documents were fourth and PCT documents fifth; and4. (4) the most common languages used by the examiners carrying out these searches were English and Chinese.
