Minecraft looks very similar to original Wolfenstien or Ultima Online. Probably a bunch of earlier games that used blocks of simple textures. It's not an original art style, and it's not gonna stand up in any fair court. Notch never claimed that he invented the graphical style of Minecraft. He deliberately used low complexity graphics for ease-of-use and the ability to create large, performant maps.
