Where can I find data to create my own statistics?
There are 4 EPO products that allow extraction of data and/or statistics. Each of the products contains worldwide patent data.
Espacenet
The filter module in Espacenet offers basic filtering functions that provide statistical analyses and visualisations of query results on predefined categories such as publication countries, applicant and inventor names and countries and classification symbols. Boolean operators (AND, OR, NOT) can be used between the filter items to build more advanced filtering and statistical analyses. Filters may be applied on publication or patent family level.
Global Patent Index (GPI)
GPI is a subscription product, and you can obtain a 1-month free access to evaluate it. The data is updated weekly, and searches are formulated using an intuitive and easy to learn query syntax. GPI allows for much more advanced searching then what Espacenet allows. GPI has a statistics window that delivers ready to use simple graphs or cross reference graphs. These graphs can be downloaded in JSON or CSV format. GPI also allows users to download a user defined list of the search results (max 50 trial / 10.000 subscription) which can then be used to create graphs or tables using your own visualisation or analysis tools.
PATSTAT Online
PATSTAT Online is a subscription product but you can obtain a 1-month free access to extract the data or graphs you need. The data is updated 2 times per year and searches are formulated using SQL. PATSTAT Online gives you full freedom to combine any of the data attributes or tables in using SQL queries, but it is a strictly read-only platform. PATSTAT Online has a statistics window that delivers ready to use simple graphs or cross reference graphs similar to GPI. PATSTAT Online also allows users to download result lists (max 10.000 – free version- / 700.000-with subscription- rows) which can then be used to create graphs or tables using your own visualisation or analysis tools. PATSTAT Online also allows data base extractions (MS ACCESS or CSV) based on a result list of maximum 100.000 patent applications.
PATSTAT Global
PATSTAT Global is a subscription product. It is EPOs flagship product for users who want to conduct complex and sophisticated data analysis. The data is updated 2 times per year and delivered as a set of CSV files representing a readymade relational data base. Hosting PATSTAT at your premises gives you full freedom to aggregate, link or manipulate the data using whatever tools, platform, or hosting environment you want. Users can make use of the many non-EPO data sets that can be linked to PATSTAT. Because of its flexibility and generous terms of use, PATSTAT Global is the preferred data base to conduct econometric analysis. Users are often academia, policy, and research institutes.
