New patents are issued by the USPTO on Tuesdays. Both of today's Spotlight Patents continue our theme of blockchains (smart contracts, distributed ledgers) and rights management broadly construed. Assigned to Adobe, the first patent addresses a smart contract platform for generating and customizing smart contracts. Assigned to Eluvio, the second patent addresses techniques for publishing digital content in a decentralized content fabric.
10,880,074, "Smart contract platform for generating and customizing smart contracts," assigned to Adobe.
Embodiments relate to a smart contract platform that facilitates creation, execution and verification of customized smart contracts. The smart contract platform enables design of customized smart contracts for execution and verification on a distributed ledger network, including smart contracts with logic for querying and fetching sensitive transactional data from participant nodes. A distributed ledger can store tokens indicating successful completion of one or more transaction elements without making some or all the associated transactional data visible. A smart contract form viewer can be used to view and interact with a smart contract form linked to the smart contract. The smart contract form can present contractual provisions in natural language, present transactional data to an authorized user, and accept entry or validation of designated transaction data. As such, the smart contracts described herein provide visibility and verifiability without the lost privacy and lack of customizability that exist with present solutions.
10,880,200, "Publishing digital content in a decentralized content fabric," assigned to Eluvio, Inc.
Disclosed are examples of systems, apparatus, devices, computer program products, and methods implementing aspects of a decentralized content fabric for publishing digital content to an overlay network. In some implementations, fabric nodes of the overlay network are implemented in an application layer differentiated from an internet protocol layer. A first fabric node is configured to: obtain a client request to publish a content object part to the overlay network; determine a target partition of the overlay network in which to store the content object part; send a network request to provide the content object part to a second one or more fabric nodes; obtain one or more messages indicating that the second one or more fabric nodes stores the target partition; and publish the content object part to the second one or more fabric nodes for storage.
