Launch a Blockchain-Based Patent Registration and Verification System
Use blockchain to secure intellectual property through immutable timestamps, inventor verification, and transparent ownership tracking.Traditional patent registration is slow, opaque, and vulnerable to tampering. Blockchain ensures tamper-proof, time-stamped, and publicly verifiable ownership records that reduce legal disputes and improve transparency for innovation claims.
Develop a decentralized platform where inventors can register patents by submitting hashed documents, receive immutable proof of ownership and timestamp, and allow anyone to verify originality and submission time through the blockchain.
Patent Hash Timestamping
Inventors upload their work, which is hashed and timestamped on-chain to prove creation date.
Ownership Registry
Smart contracts store the submitter’s address, hash, and timestamp as proof of authorship.
Public Verifiability
Anyone can verify a patent claim by comparing document hashes with on-chain entries.
Transferable IP Rights
Allow optional transfer of patent rights via smart contract-based ownership reassignment.
Users upload a document, and a cryptographic hash (SHA-256 or Keccak-256) is generated in the frontend. The hash, submitter wallet address, and timestamp are stored in a smart contract. Ownership can be verified or transferred by querying the blockchain with the hash.
- Solidity smart contracts for patent entries and transfers
- Frontend interface for file upload, verification, and search
- Local hash generation using CryptoJS or ethers.utils
- MetaMask login and signer identity verification
- Optional IPFS storage for non-confidential patent content
Blockchain
Ethereum or Polygon for secure and public recording
Smart Contracts
Solidity with mapping of hash → owner and timestamp
Frontend
React.js with Web3.js/Ethers.js and file hashing
Storage
IPFS for optional document upload and metadata storage
1. Create Smart Contract for Patent Registry
Store hashes of patent documents with timestamp and wallet address.
2. Build File Hashing and Upload Interface
Use CryptoJS to generate SHA-256 or Keccak256 hash of files in-browser.
3. Enable On-Chain Verification
Allow users to input a document and check if it matches an existing registered hash.
4. Add Ownership Transfer Logic
Support patent ownership transfers with wallet signatures and history logging.
5. Deploy Test Registry with Sample Patents
Register mock patents on a testnet and test the full flow of timestamping and verification.
Secure Innovation with Blockchain-Powered Patent Registration
Protect intellectual property, eliminate disputes, and prove authorship in real-time using decentralized records.
