Invention
Rubik’s Cube, which is also known as Magic Cube, was invented by Hungarian professor of architecture Ernő Rubik. He received a Hungarian patent on his invention in 1977. Later, in 1981, so-called patent of importation (brevet d’importation) for Rubik’s Cube was obtained in Belgium. However, for various reasons, Rubik failed to secure patent protection in further countries
