Overview
The surge in blockchain, cryptocurrency, and decentralized finance (DeFi) applications has driven a significant increase in patent filings worldwide. Blockchain—a distributed ledger technology secured by cryptography—offers tamper-resistant record-keeping, initially powering financial transactions but now expanding into healthcare, logistics, cybersecurity, and consumer electronics.
