The graphics in the patent are quite a bit different from the game. The mousers are in different poses, on the LCD the underwater turtles have bubbles coming up from their mouths, the design of the bomb is sticks of TNT in the patent but a cartoon bomb on the LCD, etc. But everything is in the right place, it looks like.

Also, April's graphics were significantly improved. It may not be a good idea to rely on the patents for getting these graphics, although perhaps those (sometimes) different ROMs and graphics could be added to MAME as alternate "(patent)" sets?

For reference:
