Application: System and method for tracking and controlling print cartridge ownership transfers using non-fungible tokens (Patent ID: US20240086910A1)

The patent filed by Toshiba Corp. describes a system and method for tracking and controlling print cartridge ownership transfers using non-fungible tokens (NFTs) stored on a public blockchain. Each manufactured print cartridge is associated with a unique NFT encoded with a serial number and manufacturer information. The NFT includes transactional information and a smart contract, enabling the sale or resale of cartridges on a digital marketplace governed by smart contract terms. Buyers can scan a cartridge QR code to access information on the blockchain, allowing for authorized ownership transfers.

The system includes a processor and memory storing an electronic ledger with a blockchain containing NFTs linked to unique print cartridge identifiers. The processor can receive ownership transfer requests, allow transfers based on smart contract terms, and update transactional information on the blockchain. Transactional information includes seller and buyer details, and the system can also handle status inquiries and transactional fees specified by the smart contract. The method involves scanning cartridge indicia to generate a unique identifier, querying the blockchain for ownership information, and requesting ownership transfers through a server. Fees for completed transfers can be assessed and paid accordingly, ensuring secure and transparent ownership tracking for print cartridges.
