    We document the generation and the content of the Comprehensive Patent Database (CPDB) of the German Democratic Republic (GDR) (1949–1990), which is freely available at GESIS . The database contains all patents granted in the GDR and published by the Office of Inventions and Patents (later: German Patent and Trade Mark Office/DPMA). The core database covers the years 1950–1990 and contains 24 variables with manually cleaned and processed information on a total of 261,822 unique patents of the GDR.
