Patents
The aesthetic appearance of the Zocchihedron was protected by United States design patent D303,553, which expired on 19 September 2003. There was never a utility patent for the original Zocchihedron, although United States patent 6,926,276 may protect the braking mechanism of the Zocchihedron II. That patent will expire on 9 August 2025 and applies only to 100-sided dice containing "multi sized and irregularly shaped particles."
