Geert Boedt (EPO), Helene Dernis (OECD) and myself have written a 10-page introduction to the offline Patstat database. The article provides MySQL and SQL codes for several popular queries:
- How to identify patent applications by technology field
- How to identify PCT patent applications
- How to know whether a patent application is a priority filing
- How to compute the patent family size
- How to count patents by country of inventor/applicant
- How to identify patents resulting from international collaboration
- How to count citations
- How to know whether a patent was granted
- How to link Patstat with external databases
If you are new to Patstat, then it is a great starting point. If you are already familiar with Patstat, the article is a good way of validating your queries!
You can download the article free of charge:

The source code as well as a sample MS Access database for those of you who don’t have Patstat installed is available from Run My Code website.
The article is forthcoming in the Australian Economic Review:
de Rassenfosse, G., Dernis, H. & Boedt, G., 2014. "An introduction to the Patstat database with example queries". Australian Economic Review 47(3), 395-408.
PS: You may also be interested in a previous related topic on the worldwide count of priority filings.
Here you can post your opinions, ask questions and share experiences on the PATSTAT product line. Please always indicate the PATSTAT edition (e.g. 2015 Autumn Edition) and the database (e.g. PATSTAT Online, MySQL, MS SQL Server, ...) you are using.
