How does a Lego brick differ from Rubik’s Cube?
They have much in common. Both of these creative toys develop dexterity, logical thinking skills and imagination. But the European Court of Justice has held that the shape of Lego bricks is determined solely by their functional characteristics, while the EU’s General Court has found the opposite to be true of the shape of Rubik’s Cube. In practice this means that a graphic presentation of a Lego brick cannot be a trademark, but a graphic presentation of Rubik’s Cube can.
