New pending patent applications are published on Thursdays. This week's Spotlight Applications continue the theme of blockchains (smart contracts, distributed ledgers) and rights management broadly construed. Assigned to Microsoft, the first applications discloses techniques for blockchain smart contracts for digital asset access. Assigned to Nonprofit Organization Cyber Campus Consortium TIES (JP), the second application discloses techniques for using a content contract in blockchain, and content management system and content provision method using same.
20200162473, "Blockchain smart contracts for digital asset access," assigned to Microsoft.
A computing device includes a communications interface that communicatively couples the computing device with a plurality of other computing devices that collectively maintain a blockchain. A storage machine holds a plurality of blocks comprising the blockchain, where a particular block of the plurality defines a smart contract. The smart contract includes: (i) a first access criterion granted to an entity for a digital asset, and (ii) one or more functions that, when an associated condition is satisfied, change the first access criterion to a second access criterion, the condition being satisfied when one or more variables have specific values. A logic machine is configured to receive a current value of a variable and determine that the current value satisfies the associated condition. A request is transmitted to the plurality of computing devices to update the first access criterion to the second access criterion.
20200160466, "Content contract in blockchain, and content management system and content provision method using same," assigned to Nonprofit Organization Cyber Campus Consortium TIES (JP).
In the present invention, when a provider of content publishes content on a Web page, an SNS, or the like online, such as on the Internet, a blockchain is used to prevent undesired browsing, quoting, and downloading. A content contract, which is a new tool for enforcing ownership according to the present invention, is stored in a blockchain. A contract portion describing an enforcement condition for performing licensing, and a method portion describing an enforcement program for performing licensing in accordance with the above-described enforcement condition are described in the content contract, and a metadata portion is provided in the content contract. Attribute information and location information such as a URL or URN for referencing an online external storage storing the data of the content is described in the metadata portion.
