Abstract
Abstract 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 https://doi.org/10.7802/2448. 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.

Die Jahrbücher für Nationalökonomie und Statistik existieren seit dem Jahr 1863. Die Herausgeber fühlen sich der Tradition verpflichtet, die Zeitschrift für kritische, innovative und entwicklungsträchtige Beiträge offen zu halten. Weder thematisch noch methodisch sollen die Veröffentlichungen auf jeweils herrschende Lehrmeinungen eingeengt werden.
