Japanese tech conglomerate Sony has submitted patent applications for two hardware products utilizing blockchain applications with the United States Patent and Trademark Office (USPTO), underscoring the company’s thrust to push blockchain development.
According to a report by MoneyControl, Sony applied for patents titled “Electronic Node and Method for Maintaining a Distributed Ledger” and “Device and System,” which described the devices and systems to be used in the maintenance of a ledger.
It said the first patent request provides “an electronic device for maintaining a distributed ledger…comprising circuitry configured to perform a mining process of a block to be added to the distributed ledger, wherein the mining process includes compressing data of the block to be added to the distributed ledger.”
The document added that the system could be used to maintain a distributed ledger or more commonly known now as a blockchain, MoneyControl added.
In the second application, it refers “to a device for accessing a distributed ledger and a system for maintaining a distributed ledger.” The report noted that the two applications are related in usage, with the device used for accessing distributed ledger while the system provides for defining and maintaining a blockchain.
According to the report, this is not the first time the tech giant has applied for a patent for its hardware for application of the blockchain technology.
In November last year, Sony applied for a patent to apply blockchain in the education field. The application was titled, “Electronic Apparatus, Method for Electronic Apparatus and Information Processing System” was published by USPTO and provided details on its collaboration with IBM to develop and implement the project.
In April, Sony also applied for a patent to store digital rights data using blockchain.
Sony, with its digital rights management (DRM) solutions, aims to establish interoperability which
“may not be very reliable and rely on one unique point of failure. If the rights locker provider or system goes out of business or otherwise fails, the user loses all the acquired content.”
The filing said that with blockchain, users could store the necessary identification information that allows them to watch the products they purchase.
