Blockchain PKI

5 granted and 1  pending USPTO patents

Patents and applications concern low-level blockchain handling of cryptographic keys used for identity and ownership (analogous to bank account numbers, but on a blockchain), and in particular generation, announcing and revoking said keys.

These patents have general wide applicability across numerous blockchain applications: finance, cryptocurrency, supply chain, IoT, and identity.

Databases

2 granted and 2 pending USPTO patents

Applications concern the management of data transfer and synchronization between traditional databases and blockchains.

These applications have applicability to integrating data management systems with blockchains.

Internet of Things

2 granted and 1 pending USPTO patents

Patent and applications concern the management and tracking of IoT
devices in a decentralized manner using blockchain, and in particular
managing and verifying device identities and permitted device access.

These patents and applications have applicability in wide-scale IoT device deployment, device security (e.g. against hackers) and improved manufacturing efficiencies.

Other

3 granted and 1 pending USPTO patents

Applications in this category address a number of different topics: improvements to fundamental blockchain methods of operating, copyright and digital rights management, RFID authentication, and a distributed blockchain-based certificate authority.
