New patents are issued by the USPTO on Tuesdays. This week's Spotlight Patents concern aspects of blockchains (smart contracts, distributed ledgers) and rights management broadly construed. Assigned to Intel, the first patent address a blockchain system with nucleobase sequencing as proof of work. Assigned to Eluvio, the second of this week's patents addresses techniques for a decentralized system for distributing digital content.
10,796,000, "Blockchain system with nucleobase sequencing as proof of work," assigned to Intel.
A sequence mining platform (SMP) comprises a processor, at least one machine-accessible storage medium responsive to the processor, and a sequence manager in the machine-accessible storage medium. The sequence manager is configured to use processing resources to determine a sequence of nucleobases in a nucleic acid. The storage medium also comprises a blockchain manager to (a) collect transaction data for one or more transactions for a blockchain which requires a proof of work (POW) for each new block; and (b) include at least some of the transaction data in a new block for the blockchain. The storage medium also comprises a sequence mining module (SMM) to use the determined sequence of nucleobases from the sequence manager to create a POW for the new block. In one embodiment, the SMM enables an entity which controls the SMP to receive transaction rewards and sequencing rewards. Other embodiments are described and claimed.
10,797,994, "Decentralized system for distributing digital content," assigned to Eluvio, Inc.
Disclosed are examples of decentralized systems and related apparatus, devices, computer program products, and methods for distributing digital content. In some implementations, an overlay network of fabric nodes is implemented in an application layer differentiated from an internet protocol layer. One or more network-wide parameters and a node identifier (ID) identifying a fabric node are obtained. A set of partition identifiers (IDs) for the node ID is determined using the one or more network-wide parameters. The partition IDs identify partitions to be managed by the fabric node. At least a portion of digital content in the overlay network can be distributed using a partition ID.
