PATSTAT (i.e. EPO Worldwide PATent STATistical Database) is a single patent statistics raw database, held by the European Patent Office (EPO) and developed in cooperation with the World Intellectual Property Organisation (WIPO), the OECD and Eurostat. PATSTAT provides raw patent data coming from around 90 patent offices worldwide, including of course the most important and largest ones such as the European Patent Office (EPO) and the United States Patent and Trademark Office (USPTO).
A major problem with PATSTAT is that data are provided in a raw format. Data coming from PATSTAT have been therefore thoroughly elaborated by CRIOS to produce a cleaned and harmonized database: PATSTAT-CRIOS1. Data processing consisted mainly in a thorough work of cleaning and standardization of rough information provided by the EPO.
Yearly time series (by country, region, or company) always begin with the first year of activity (first year with a non-zero figure) and end with the last year of activity (last year with a non-zero figure).
2 Among them, we have often adopted a technology-oriented classification, jointly elaborated by Fraunhofer Gesellschaft-ISI (Karlsruhe), Institut National de la Propriété Industrielle (INPI, Paris) and Observatoire des Sciences and des Techniques (OST, Paris). This classification aggregates all IPC codes into thirty technology fields.
