rubik cube's uses
« on: 11-27-17 at 12:14 pm »

hello everybody,

I have an idea of a new game that uses the rubik cubes technology (mechanization). the cube is all in one color .
Does the rubik cube have patent? I saw that it was invented in 1947, and read in some places that thet still havr patent (in rubik cube site) and in other places that they had copyright for only 20 years...
any idea how to know which case is true without consulting a layer in this stage?   

Thank you!
