Import PATSTAT into MySQL

European Patent Office (EPO) database PATSTAT is a snapshot of the EPO master documentation database (DOCDB) with worldwide coverage, containing approximately 20 tables including bibliographic data, citations and family links.

PATSTAT is shipped as a bunch of zipped, csv files spread across multiple DVDs. Unfortunately, existing scripts and documentation only help users loading raw data into MSSQL databases.

This utility wants to make it easy for everyone to build a PATSTAT MySQL database from raw csv data. To achieve high-performances, database tables are compressed.

Currently, there is full compatibility with version Spring 2016, also known as 2016a.

The utility is also capable of loading the standardized EEE-PPAT person table with harmonized assignee names and assignee sector allocations (https://www.ecoom.be/en/EEE-PPAT). This table has been officially included in version 2015a.

Prerequisites

Every zipped table file tlsXXX_partYY.zip found in PATSTAT DVDs should be copied into a single folder. TLS221_INPADOC_PRS DVD zipped table may be copied there as well.

Usage

Run load_patstat.sh without parameters to display a brief help. Mandatory parameters are mysql_user and password, as well as MySQL database host and name. Optionally, a -v may be passed to obtain a verbose output. For testing purposes one may want to pass the modifier -t to only loads small portions of zipped csv files. Output and error logs are written to output_log_YYYY-MM-DD and error_log_YYYY-MM-DD in the current workind directory. One may specify a different directory using the modifier -o.

$ ./load_patstat.sh
Usage: [-v] [-t] -u mysql_user -p mysql_pass -h mysql_host -d mysql_dbname -z patstat_zips_dir
  -v: be verbose
  -t: load small chunks of data for testing purposes
  -z: directory containing patstat zipped files shipped in DVDs (defaults to ./data)
  -o: output and error logs directory (defaults to ./)

Examples

Load a test PASTSTAT database and the standardized person table into a MySQL database on localhost named patstat2016a -- note the -t modifier. Zipped table files have been placed into the default folder ./data.

$ ./load_patstat.sh -u<USER> -p<PASSWORD> -hlocalhost -d patstat2016a -t -n

Load a full PATSTAT database and the standardized person table into a localhost MySQL database patstat2016a. Again, zipped table files have been placed into the default folder ./data.

$ ./load_patstat.sh -u<USER> -p<PASSWORD> -hlocalhost -d patstat2016a -n

Troubleshooting

This utility must have write privileges into MySQL data folder. This is necessary to compress database tables and to work with table indices. Make sure the user that executes load_patstat.sh has such privileges.
