New pending patent applications are published by the USPTO on Thursdays. Both of today's Spotlight Applications concern aspects of blockchains (distributed ledgers, smart contracts) and rights management broadly construed. Assigned to Walmart, the first application discloses techniques for automatically authorizing digital rights access. Assigned to Duvon, the second application discloses techniques for autonomous exchange via entrusted ledger immutable distributed database.
20190325115, "Systems and methods for decentralized content distribution," assigned to Walmart.
In some embodiments, systems, apparatuses, and methods are provided herein useful to automatically authorizing digital rights access. In some embodiments, the system comprises a content creator server, wherein the content creator server is configured to create a block, wherein the block includes the content, publish, to a public ledger, the block, wherein the public ledger comprises a blockchain, generate, for a user device, a key, wherein the key provides digital rights access to the block, and transmit, to the user device, the key, the user device configured to store a local copy of the public ledger, update the local copy of the public ledger to include the block, receive, from the content creator server, the key, and access, via the local copy of the public ledger with the key, the block, wherein access to the block allows the user device to make use of the content.
20190324958, "Autonomous exchange via entrusted ledger immutable distributed database," assigned to Duvon Corporation.
An Autonomous Exchange via Entrusted Ledger (AXEL) blockchain is discussed herein. The AXEL blockchain enables users to perform transactions in a private setting while enabling the transaction records thereof to be verified by other network users without publicly divulging the contents or details of the transaction records. The token identification system and method allows the tokens to carry an immutable identification to prevent negative blockchain occurrences such as double spending. A payment methodology allowing integration of external financial institutions with user owned and managed wallet. The AXEL blockchain can also interface with and utilize a distributed database to create an immutable record of each transaction while providing a complete backup of the transactions that occur within the system and on the AXEL blockchain.
