The Rubik’s Cube, a multicolored three-dimensional puzzle, that has been a fixture in children’s toy boxes for forty years.<br /><br /> Invented in 1974 by Hungarian Erno Rubik, 350 million cubes have been sold worldwide.<br /><br /> And the fiendishly difficult puzzle has kept lawyers and judges busy for a decade.<br /><br /> The British company, which owns the rights, registered the shape as an EU trademark in 1999.<br /><br /> A German firm challenged that in 2006, the shape of the cube alone is not enough to protect it from being copied.<br /><br /> It took its legal challenge all the way to the European Court of Justice and judges agreed.<br /><br /> The ruling means other companies can create similar puzzles.<br />
