Algeria and Bulgaria, Czechoslovakia, the Democratic Republic of Germany, the Soviet Union and other countries, in addition to establishing the patent system, also adopted the inventor certificate system.

Mexico adopts the invention certificate system. Inventors have the right to exploit inventions, but they can't refuse others to use them, but they can get certain rewards approved by the state.
