Abstract

The article analyses quantitatively the bibliographic searches such as cumulative search reports, SDI (Selective Dissemination of Information) searches and applicant-inventor searches of the office of the Patent Information System (PIS) provided during the period from 1 March 1984 to 31 December 1988. A list of the primary and secondary sources on which the services are based is given. All the searches carried out during this brief period have been analysed in terms of searches for Indian patents through the Indian Patent classification scheme, and the Gazette of India, Part III Section 2, searches through the International Patent Classification (IPC), SDI searches through IPC and patent applicant/inventor searches. Analyses are made as to who are the actual users of these services and the services used by these users have been analysed in terms of their subject interest. Conclusions have been drawn in a tabular form on the basis of the tables and the analysis of the contents therein.
