The patent, titled "Tracking Unique In-Game Digital Assets Using Tokens on a Distributed Ledger" shows a theoretical mechanism for tracking the changes to in-game assets, including ownership, visual appearance and Metadata.
In the description of the patent, it says – "Individuals often find it meaningful to own or use unique physical items related to respected celebrities or activities."
"In traditional video games, multiple instances of the same in-game item exist within the same copy of the video game and/or within different copies of the video game. These different instances of the same in-game item are traditionally fungible, as they are indistinguishable from one another," says the patent description.
Sony envisions a system where players can trade unique in-game items, which are verified for authenticity via the blockchain.
Sony's patent describes technology that could track the history of an in-game item as it's passed from player to player, which is one of the core ideas behind NFTs.
The patent further noted — "The digital assets may be video game digital media assets representing moments of gameplay of a video game, such as video clips or images. The digital asset is created, and a distributed ledger tracking a history of the digital asset is created and stored across devices."
Sony Interactive Entertainment Inc. filed for this patent in May last year, which gets published this month. This patent is for video games and notably Sony Interactive Entertainment Inc is owner of video gaming brand 'PlayStation'.
A few weeks ago, PlayStation launched a program called PlayStation Stars, a rewards program, with rewards for in-game accomplishments, that the company insisted were not NFTs, but after learning about this patent, it could be a Sony's anticipated move for NFTs.
