Abstract: This paper documents the generation and the content of the Comprehensive Patent Database (CPDB) of the German Democratic Republic (GDR) (1949-1990), Version 1.1, which is freely available at GESIS https://doi.org/10.7802/2423. The database contains all patents granted in the GDR and published by the Office of Inventions and Patents (AfEP, later: German Patent and Trade Mark Office/DPMA) in the period between 1 January 1939 (application before but granted in the GDR) and 29 June 2006 (application in but granted after the GDR). The core database covers the years 1950 to 1990 and contains 24 variables with manually cleaned and processed information on a total of 261,822 unique patents of the GDR. The data was collected and prepared for the purpose of research on innovation activity in the GDR.
