Immutable License Grant Records for Authorized Derivative Works
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current blockchain-based systems lack a mechanism to verify the authorization of derivative works, making it difficult for potential buyers to determine if a digital asset was created with the permission of the original copyright holder, leading to potential copyright infringement issues.
Innovation Solution
A system that enables creators to authorize derivative works on a blockchain, providing an immutable record of permission, allowing buyers to verify the legitimacy of derivative NFTs through a license registry service and smart contracts, ensuring that derivative works are created with proper authorization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If blockchain technology is used to store NFT ownership records, then ownership verification is improved, but the ability to verify copyright authorization and derivative work permissions deteriorates
Solution Approach 1:
The patent segments the blockchain data structure into separate functional components: one section stores ownership information (token holder, creator) while another section stores copyright license information (grantor, grantee, permissions). This segmentation allows the system to maintain precise ownership verification while simultaneously preserving copyright authorization information that would otherwise be lost in traditional NFT implementations.
2Ease of operation
If traditional NFT systems are used, then transaction simplicity is maintained, but the ability to track and verify derivative work authorization deteriorates
Solution Approach 1:
The patent implements preliminary action by automatically capturing and storing copyright license information at the moment of NFT creation and transfer. The smart contract code is pre-configured with license terms, and the blockchain automatically records authorization details before any derivative work is created. This eliminates the need for separate tracking systems while maintaining transaction simplicity.
3Reliability
If copyright license information is stored on-chain, then authorization verification is improved, but storage costs and technical complexity increase
Solution Approach 1:
The patent applies universality by designing a multi-functional smart contract that simultaneously handles ownership transfer, copyright license management, and derivative work authorization verification. The same blockchain infrastructure and smart contract mechanism serve multiple purposes: tracking token ownership, storing license terms, and verifying derivative work permissions. This consolidates what would otherwise require separate systems into a single unified platform.

AI summary
Systems and methods are described for generating and storing immutable blockchain records with respect to authorized derivative works based on content associated with a non-fungible token (NFT). For example, a first NFT stored on a blockchain may be owned by a first blockchain address, and that owner may cryptographically sign a message indicating or representing that the individual approves of a created or to-be-created second NFT that is based at least in part on content of or associated with the first NFT. The cryptographic signature may be authenticated, and then a system may generate new data for storage in a new blockchain record. The new blockchain record may identify both the first NFT and the second NFT, and also include data proving that the owner of the first NFT approved of the second NFT.
