Sony’s Gaming Innovation: ‘Super-Fungible Tokens’

Sony’s Patent Application

Gaming giant Sony has filed a patent application for “super-fungible tokens” specifically designed for gaming. The application, submitted in 2022, outlines a system that tracks gaming assets and creates these unique tokens.

What are Super-Fungible Tokens?

Super-fungible tokens are essentially a bundle of non-fungible tokens (NFTs) that represent ownership of a specific gaming asset. This means that each token represents a unique item within a game, such as a weapon or character.

How it Works

The system proposed in the patent application involves an electronic device that monitors gaming assets and creates super-fungible tokens. These tokens are stored on a distributed ledger, such as the Ethereum blockchain.

Sony’s Metaverse Ambitions

Sony’s patent application is part of its broader push into the gaming metaverse. In 2022, the company invested $1 billion in Epic Games, the developer of the popular game Fortnite. This investment suggests that Sony is exploring ways to enhance its gaming experiences through virtual and digital assets.


Sony’s patent application for super-fungible tokens highlights the company’s commitment to innovation in the gaming industry. By creating a system that allows for the tracking and ownership of unique gaming assets, Sony aims to enhance the gaming experience for its players.
