Sony submits patent application for in-game asset: game characters, items, and scenes can be created as unique tokens
Sony's US office has filed a patent with the World Intellectual Property Organization (WIPO) for a distributed ledger system that purportedly tracks digital assets within games using distributed ledger tokens. The patent application was filed last year and recently made public, but was rejected due to the abstract nature of the concept and the difficulty of integrating it into practical applications.

Cross-Device Storage of In-Game Assets or Characters
The patent describes a system and method for tracking digital assets in video games. Digital assets refer to in-game items or characters, as well as scenes or images within the game.
It states that these digital assets can be created and tracked historically through a distributed ledger, and can exist across different devices. These digital assets would be unique tokens containing identifiers and metadata to identify the assets. Ownership, appearance, and metadata of the digital assets can be updated. This concept sounds similar to NFTs, although the term is not explicitly mentioned.
The concept of blockchain in the patent is subtly discussed, mentioning that the distributed ledger will produce new blocks to identify changes in data, and will include the hash value of the previous block.
