The RISIS Patent database derives from the EPO PATSTAT (Version April 2017), a database provided by the European Patent Office and considered as a reference in the field of patent intelligence and statistics. It contains bibliographical patent data from leading industrialised and developing countries. Building on competencies accumulated over the years and mobilizing dedicated resources, IFRIS UPEM, as a research center specialized in quantitative STI, has incorporated in the RISIS Patent database a series of improvements, stemming from outside providers or from its own proprietary developments (filling of missing data, calculations of indicators, geocoding of addresses and their allocation to functional urban areas, classification of technologies, typology of applicants).
