Almost everybody knows the Rubik’s Cube. It is not only widely recognised as the best puzzle toy ever made, but it is also one of the best-sold toys worldwide. The Rubik’s Cube was patented in Hungary. However it had obtained almost no patent protection abroad.
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
