Abstract: Information contained in patent databases can be used to show technology networks, in keeping with the theory advanced by the Centre de Sociologie de l|Ecole des Mines de Paris. Mathematics methodology is equired for the analysis of associated words. One example shows technology themes concerning food products that were obtained in this way. A second example suggests the same methodology for strategic technologies involved in wastewater purification. The article covers one means of disclosing the strategic features of a technology through simple analysis (which is neither too random nor too difficult to set up) of complementary patents.
Keywords: patents; WPIL database; EPAT database; technology life cycle; technology networks; patent analysis; strategic technologies.
