Description

[Technical field]

[0001] The present disclosure relates to industrial property distribution systems. [Background technology]

[0002] Patent Document 1 discloses a system for supporting the circulation of intellectual property rights. In the system disclosed in Patent Document 1, a terminal of a contributor who contributes intellectual property rights, a terminal of an investor, and a terminal of a user are connected to a management server via a network. A series of information related to the intellectual property rights contributed by the contributors is stored in a management database connected to the management server.

[0003] [Patent Document 1] JP 2003-141307 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, it is difficult to say that a situation in which a series of information related to the distribution of industrial property rights such as patent rights is centrally managed on the management database of the management server is desirable. For example, there is a risk that information related to industrial property rights on the management database may be tampered with due to cyber attacks from third parties. Furthermore, business companies and investors who purchase industrial property rights need to consider the credit risk of the platform operator that manages the distribution of industrial property rights before trading industrial property rights. For this reason, in a situation in which the distribution management of industrial property rights is carried out using only a centralized management database, the credit risk of the platform operator that manages the management database becomes a hindrance, making it difficult to increase the trading volume and liquidity of industrial property rights. In addition, transactions of industrial property rights such as patent rights should be carried out on a global scale (in other words, borderless) via the Internet, and there is a need to build an industrial property rights distribution platform that is highly convenient and reliable for domestic and foreign investors and business companies.

[0005] In view of the above, the present disclosure aims to provide an industrial property rights distribution system capable of realizing smooth and safe transactions of industrial property rights or rights arising from the industrial property rights, and in particular, to provide a patent rights distribution system capable of realizing smooth and safe transactions of patent rights. [Means for solving the problem]

[0006] An industrial property rights distribution system according to one aspect of the present disclosure includes a blockchain network composed of a plurality of nodes each having a blockchain, a first terminal communicatively connected to the blockchain network and associated with a first user who sells an industrial property right or a right derived from the industrial property right, an intermediary server communicatively connected to the blockchain network and the first terminal and associated with an intermediary who mediates transactions of the industrial property right or the right derived from the industrial property right, and a second terminal communicatively connected to the blockchain network and the intermediary server and associated with a second user who purchases the industrial property right or the right derived from the industrial property right. The industrial property rights distribution system distributes a first issuance request to the blockchain network to issue a non-fungible token associated with the industrial property right or the right derived from the industrial property right on the blockchain, records the non-fungible token on the blockchain in response to the first issuance request, distributes a second issuance request to the blockchain network to issue a smart contract on the blockchain that specifies that the non-fungible token will be sold at a predetermined selling price, records the smart contract on the blockchain in response to the second issuance request, and records information indicating that the non-fungible token is being sold at the predetermined selling price on the second terminal. The smart contract is displayed on a terminal, and in response to an input operation of the second user on the second terminal, a remittance request for transferring cryptocurrency in an amount equivalent to the specified selling price to the smart contract is transmitted to the blockchain network, and the smart contract is invoked in response to the remittance request, thereby recording information on the blockchain indicating that the owner of the non-fungible token has been changed to the second user, and recording information on the blockchain indicating that cryptocurrency in an amount obtained by multiplying the amount equivalent to the specified selling price by a specified rate, or cryptocurrency in an amount obtained by deducting a specified amount from the amount equivalent to the specified selling price, has been transferred to the first user.The non-fungible token represents a right to be the owner of the industrial property right or a right arising from the industrial property right.

[0007] According to the above configuration, smooth and secure transactions of industrial property rights or rights arising from industrial property rights can be realized through the buying and selling of non-fungible tokens associated with industrial property rights or rights arising from such industrial property rights via smart contracts.

[0008] An industrial property rights distribution system according to one aspect of the present disclosure includes a blockchain network composed of a plurality of nodes each having a blockchain, a first terminal communicatively connected to the blockchain network and associated with a first user who sells an industrial property right or a right derived from the industrial property right, an intermediary server communicatively connected to the blockchain network and the first terminal and associated with an intermediary who mediates transactions of the industrial property right or the right derived from the industrial property right, and a second terminal communicatively connected to the blockchain network and the intermediary server and associated with a second user who purchases the industrial property right or the right derived from the industrial property right. a) The intermediary server distributes a first issuance request to the blockchain network to issue a non-fungible token associated with the industrial property right or the right derived from the industrial property right on the blockchain. b) In response to the first issuance request, each of the nodes records the non-fungible token on the blockchain. c) The intermediary server distributes a second issuance request to the blockchain network to issue a smart contract on the blockchain that specifies that the non-fungible token will be sold at a predetermined selling price. d) Each of the nodes records the smart contract on the blockchain in response to the second issuance request. e) The second terminal displays information indicating that the non-fungible token is being sold at the predetermined selling price. f) The second terminal distributes a remittance request to the blockchain network to remit cryptocurrency in an amount equivalent to the predetermined selling price to the smart contract in response to an input operation of the second user on the second terminal.g) By invoking the smart contract in response to the remittance request, each of the nodes records on the blockchain information indicating that the owner of the non-fungible token has been changed to the second user, and records on the blockchain information indicating that cryptocurrency in an amount obtained by multiplying the amount equivalent to the specified selling price by a specified rate or cryptocurrency in an amount obtained by deducting a specified amount from the amount equivalent to the specified selling price has been remitted to the first user. The non-fungible token represents the right to become the owner of the industrial property right or a right derived from the industrial property right.

[0009] According to the above configuration, smooth and secure trading of industrial property rights or rights arising from industrial property rights can be realized through the buying and selling of non-fungible tokens associated with industrial property rights or rights arising from industrial property rights via smart contracts.

[0010] The industrial property rights distribution system according to one aspect of the present disclosure executes transactions of industrial property rights or rights arising from the industrial property rights using a blockchain network composed of multiple nodes each having a blockchain. The industrial property rights distribution system distributes an issuance request to issue a smart contract on the blockchain that specifies the sale of a non-fungible token associated with the industrial property rights or the rights arising from the industrial property rights at a predetermined selling price, displays information indicating that the non-fungible token is being sold at the predetermined selling price, and distributes a remittance request to the blockchain network to remit cryptocurrency in an amount equivalent to the predetermined selling price to the smart contract. In response to the issuance request, the smart contract is recorded on the blockchain. By invoking the smart contract in response to the remittance request, information indicating that the owner of the non-fungible token has been changed to the user who remitted the cryptocurrency and information indicating that cryptocurrency in an amount obtained by multiplying the amount equivalent to the predetermined selling price by a predetermined rate or cryptocurrency in an amount obtained by deducting a predetermined amount from the amount equivalent to the predetermined selling price has been remitted to the user who owned the non-fungible token are recorded on the blockchain. The non-fungible token represents a right to be the owner of the industrial property right or a right arising from the industrial property right.

[0011] According to the above configuration, smooth and secure trading of industrial property rights or rights arising from industrial property rights can be realized through the buying and selling of non-fungible tokens associated with industrial property rights or rights arising from industrial property rights via smart contracts.

[0012] In addition, the industrial property distribution system may further distribute a first issuance request to issue the non-fungible token on the blockchain to the blockchain network, and the non-fungible token may be recorded on the blockchain in response to the first issuance request.

[0013] The industrial property right may be a patent right. The right arising from the industrial property right may be a non-exclusive license or an exclusive license of the patent right.

[0014] According to the above configuration, smooth and secure transactions of patent rights or ordinary licenses or exclusive licenses of patent rights can be realized through the buying and selling of non-fungible tokens associated with patent rights or ordinary licenses or exclusive licenses of patent rights via smart contracts.

[0015] A patent right distribution system according to one aspect of the present disclosure includes a blockchain network composed of a plurality of nodes each having a blockchain, a first terminal communicatively connected to the blockchain network and associated with a first user who sells a patent right, an intermediary server communicatively connected to the blockchain network and the first terminal and associated with an intermediary who mediates the transaction of the patent right, and a second terminal communicatively connected to the blockchain network and the intermediary server and associated with a second user who purchases the patent right. The patent right distribution system distributes a first issuance request to the blockchain network for issuing a non-fungible token associated with the patent right on the blockchain, records the non-fungible token on the blockchain in response to the first issuance request, distributes a second issuance request to the blockchain network for issuing a smart contract on the blockchain that specifies that the non-fungible token will be sold at a predetermined selling price, records the smart contract on the blockchain in response to the second issuance request, and displays information indicating that the non-fungible token is being sold at the predetermined selling price on the second terminal, In response to an input operation of the second user on the second terminal, a remittance request for remitting cryptocurrency in an amount equivalent to the specified selling price to the smart contract is transmitted to the blockchain network, and the smart contract is invoked in response to the remittance request, thereby recording information on the blockchain indicating that the owner of the non-fungible token has been changed to the second user, and recording information on the blockchain indicating that cryptocurrency in an amount obtained by multiplying the amount equivalent to the specified selling price by a specified rate or cryptocurrency in an amount obtained by deducting a specified amount from the amount equivalent to the specified selling price has been remitted to the first user. The non-fungible token indicates the right to become the owner of the patent right.

[0016] According to the above configuration, smooth and secure trading of patent rights can be realized through the buying and selling of non-fungible tokens associated with patent rights via smart contracts.

[0017] The non-fungible token may also be associated with attribute information of the patent right and information regarding the validity of the patent right.

[0018] According to the above configuration, a person who intends to purchase a patent right can purchase the patent right with peace of mind by checking the attribute information and the information on the validity of the patent right associated with the non-fungible token. In this way, it is possible to increase the transparency of the transaction of the patent right.

[0019] In addition, after the Patent Office procedure for transferring and registering the patent right from the first user to the intermediary is completed, the intermediary server may deliver the first issuance request to the blockchain network.

[0020] According to the above configuration, since the intermediary who issued the non-fungible token holds the patent right linked to the non-fungible token, prospective purchasers of the patent right can purchase the patent right through the non-fungible token with peace of mind.

[0021] In response to a request from the second user who owns the non-fungible token, the intermediary server may send to the second user an electronic document related to a Patent Office procedure for registering the transfer of the patent right from the intermediary to the second user.

[0022] According to the above configuration, electronic documents related to the Patent Office procedures for registering the transfer of a patent right are sent to a second user who owns a non-fungible token, thereby enabling smooth and secure trading of patent rights through the buying and selling of non-fungible tokens via a smart contract.

[0023] A patent right distribution system according to one embodiment of the present disclosure comprises a blockchain network composed of a plurality of nodes, each of which has a blockchain, an intermediary server communicatively connected to the blockchain network and associated with an intermediary who mediates transactions of patent rights, and a terminal communicatively connected to the blockchain network and the intermediary server and associated with a user who purchases the patent rights. The patent right distribution system transmits a first issuance request to the blockchain network to issue a non-fungible token associated with the patent right on the blockchain, records the non-fungible token on the blockchain in response to the first issuance request, transmits a second issuance request to the blockchain network to issue a smart contract on the blockchain that specifies the sale of the non-fungible token at a predetermined selling price, records the smart contract on the blockchain in response to the second issuance request, transmits a remittance request to the blockchain network to remit cryptocurrency in an amount equivalent to the predetermined selling price to the smart contract, and records information on the blockchain indicating that the owner of the non-fungible token has been changed to the user by calling the smart contract in response to the remittance request, and records information on the blockchain indicating that cryptocurrency in an amount obtained by multiplying the amount equivalent to the predetermined selling price by a predetermined rate or cryptocurrency in an amount obtained by deducting a predetermined amount from the amount equivalent to the predetermined selling price has been remitted to another user who sells the patent right. The non-fungible token indicates the right to become the owner of the patent right.

[0024] An information processing method according to one aspect of the present disclosure is a method for executing a transaction of industrial property rights or rights arising from the industrial property rights using a blockchain network composed of multiple nodes each having a blockchain, and is executed by a computer. The information processing method includes a step of distributing an issuance request to the blockchain network to issue a smart contract on the blockchain that specifies the sale of a non-fungible token associated with the industrial property rights or the rights arising from the industrial property rights at a predetermined selling price, and a step of outputting information indicating that the non-fungible token is being sold at the predetermined selling price. The non-fungible token indicates the right to become a right holder of the industrial property rights or the rights arising from the industrial property rights.

[0025] A program for causing a computer to execute the information processing method may be provided. Also, a computer-readable storage medium having the program stored therein may be provided.

[0026] According to one aspect of the present disclosure, an information processing device includes at least one processor and a memory that stores computer-readable instructions, the information processing device being configured to perform the information processing method when the computer-readable instructions are executed by the processor. Effect of the Invention

[Figure 6] A figure showing an example of NFT sales information on a patent rights distribution platform. [Figure 7] This is a diagram to explain the secondary distribution of NFTs linked to patent rights using an NFT trading smart contract. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0029] Hereinafter, a patent right distribution system 1 (an example of an industrial property rights distribution system) according to this embodiment will be described with reference to the drawings. FIG. 1 is a diagram showing an example of the configuration of the patent right distribution system 1 according to this embodiment. As shown in FIG. 1, the patent right distribution system 1 includes an intermediary server 4, user terminals 2a and 2b, a blockchain network 10, and an IPFS (InterPlanetary File System) 13. These components constituting the patent right distribution system 1 are communicatively connected to each other via a communication network 12. In particular, the intermediary server 4 and the user terminals 2a and 2b are communicatively connected to each other via the communication network 12. Furthermore, the intermediary server 4 and the user terminals 2a and 2b are communicatively connected to the blockchain network 10.

[0030] The communication network 12 is configured by at least one of a local area network (LAN), a wide area network (WAN), the Internet, and a wireless core network.

[0031] In this embodiment, the intermediary server 4 is associated with the intermediary 5 that mediates the transaction of the patent right 17. That is, the intermediary server 4 is a server managed and operated by the intermediary 5. The intermediary server 4 may be composed of multiple servers. In particular, the intermediary server 4 may function as a web server that manages a website and a database server that manages a database. The intermediary server 4 issues an NFT (Non-Fungible Token) associated with the patent right 17 via the blockchain network 10. Here, the NFT means a unique and non-fungible token (non-fungible token) recorded on the blockchain 8.

[0032] In addition, in this embodiment, the NFT6 associated with the patent right 17 indicates the right to become the right holder (patent holder) of the patent right 17. That is, since the owner of the NFT6 has the right to become the patent holder of the patent right 17, it is possible to become the patent holder of the patent right 17 through an application for transfer registration of the patent right 17 to the Patent Office 16. In this regard, the provision of Article 98, item 1, of the Japanese Patent Act stipulates that the transfer of the patent right (excluding those due to inheritance or other general succession) will not take effect unless it is registered. That is, for the transfer of the patent right to take effect, it is necessary to apply for transfer registration to the Patent Office 16 through the submission of an assignment deed of the patent right. Therefore, the owner of the NFT6 can become the right holder of the patent right 17 by requesting the intermediary 5 to apply for transfer registration of the patent right 17 linked to the NFT6. In addition, the owner of the NFT6 can obtain capital gains by reselling the NFT6 (i.e., the right to become the patent holder of the patent right 17) to another person. In other words, NFT6 can be bought and sold as an investment or speculation target. This will be explained in detail later.

[0033] The user terminal 2a (an example of a first terminal) is a terminal operated by the user 3a (an example of a first user). That is, the user terminal 2a is associated with the user 3a. Similarly, the user terminal 2b (an example of a second terminal) is a terminal operated by the user 3b (an example of a second user). That is, the user terminal 2b is associated with the user 3b. In this example, the user 3a is the right holder (patent holder) of the patent right 17. The user 3b is a purchaser who purchases the patent right 17 (or an NFT linked thereto) through a patent right distribution platform built by the intermediary 5. The user 3b may purchase the NFT 6 to purchase the patent right 17, or may purchase the NFT 6 for investment purposes. In the following description, the user terminals 2a and 2b may be collectively referred to simply as the user terminal 2. The users 3a and 3b may also be collectively referred to simply as the user 3.

[0034] In addition, in this embodiment, a patent right is given as an example of an industrial property right, but a utility model right, a design right, and a trademark right, which are industrial property rights other than a patent right, may be traded through the distribution system 1. That is, a utility model right, a design right, and a trademark right may be traded through the trading of NFT6 linked to the utility model right, the design right, and the trademark right. Furthermore, in the distribution system 1 according to this embodiment, a non-exclusive license and an exclusive license, which are rights arising from a patent right, may be traded through the distribution system 1. In this case, the non-exclusive license and the exclusive license may be traded through the trading of NFT6 linked to the non-exclusive license and the exclusive license of the patent right. In this respect, since a non-exclusive license is a non-action claim and registration with the Japan Patent Office 16 is not a requirement for the effectuation, the owner of the NFT6 linked to the non-exclusive license is the person who has the non-exclusive license. In addition, when a user 3a (patent holder) sells multiple non-exclusive licenses arising from a patent right 17 held by the user 3a, the user 3a may issue multiple NFT6s linked to multiple non-exclusive licenses through the blockchain network 10.

[0035] On the other hand, since an exclusive license is a real right like a patent right, the requirement for it to take effect is the registration of its establishment or transfer with the Japan Patent Office16. Therefore, since the owner of an NFT6 linked to an exclusive license has the right to become an exclusive licensee, he or she can become an exclusive licensee by requesting an intermediary5 to apply for the registration of the establishment or transfer of the exclusive license with the Japan Patent Office16.

[0036] Similarly, non-exclusive licenses and exclusive licenses arising from utility model rights and design rights may be traded through the distribution system 1. Also, exclusive licenses and exclusive licenses arising from trademark rights may be traded through the distribution system 1.

[0037] In this way, the NFT according to this embodiment represents the right to be the owner of industrial property rights (patent rights, utility model rights, design rights, trademark rights) or ordinary licenses (ordinary use rights) and exclusive licenses (exclusive use rights) arising from the industrial property rights. The rights arising from the NFT may be specified as the terms of use of the patent distribution platform. Furthermore, in order to increase the transparency of the rights of the NFT, the terms of use of the patent distribution platform specifying the rights of the NFT may be recorded on the blockchain 8 or may be stored on IPFS 13 as metadata of the NFT.

[0038] Furthermore, the industrial property rights described in this embodiment are not limited to those of Japan. In this respect, the distribution system 1 based on the WEB3 technology described in this embodiment is premised on the borderless trading of value (borderless trading of industrial property rights in this embodiment), which is the core idea of ​​WEB3, and therefore can also be used as a distribution platform for industrial property rights in the United States, Europe, China, etc. Furthermore, the users 3 are not limited to Japanese people, and may be global companies (including business companies and consulting companies) or investors (including individual investors and institutional investors).

[0039] Next, the hardware configuration of the intermediation server 4 will be described below with reference to Fig. 2. As shown in Fig. 2, the intermediation server 4 includes a control unit 40, a storage device 41, an input / output interface 42, a communication unit 43, an input operation unit 44, and a display unit 45. These elements constituting the intermediation server 4 are connected to a communication bus 46.

[0040] The control unit 40 includes a memory and a processor. The memory is configured to store computer-readable instructions (programs). For example, the memory is configured from a ROM (Read Only Memory) in which various programs and the like are stored, a RAM (Random Access Memory) having multiple work areas in which various programs and the like executed by the processor are stored, and the like. The various programs may include an information processing program that executes a series of information processing methods according to the present embodiment. The processor is configured from at least one of a CPU (Central Processing Unit), an MPU (Micro Processing Unit), and a GPU (Graphics Processing Unit), for example. The CPU may be configured from multiple CPU cores. The GPU may be configured from multiple GPU cores. The processor may be configured to load a program designated from various programs incorporated in the storage device 31 or the ROM onto the RAM and execute various processes in cooperation with the RAM. In particular, the processor may execute a series of information processes described later by loading an information processing program incorporated in the storage device 41 or the ROM onto the RAM.

[0041] The storage device 41 is, for example, a storage device (storage) such as a hard disk drive (HDD), a solid state drive (SSD), or a flash memory, and is configured to store programs and various data. The input / output interface 42 is an interface that enables a connection between an external device and the intermediation server 4, and includes an interface that complies with a predetermined communication standard such as the USB standard or the HDMI (registered trademark) standard. The communication unit 43 is, for example, equipped with a wired communication module and / or a wireless communication module for communicating with an external device connected to the communication network 12. The input operation unit 44 is, for example, a touch panel, a mouse, and / or a keyboard. It is configured to accept an input operation by an operator who operates the intermediation server 4 and to generate an operation signal corresponding to the input operation. The display unit 45 is, for example, composed of an image display such as a liquid crystal display or an organic EL display, and an image display circuit that drives and controls the image display.

[0042] Next, the hardware configuration of the user terminal 2 will be described below with reference to Fig. 3. As shown in Fig. 3, the user terminal 2 includes a control unit 20, a storage device 21, an imaging unit 22, a communication unit 23, an input operation unit 24, and a display unit 25. These elements constituting the user terminal 2 are connected to a communication bus 26. In this embodiment, the user terminal 2 is described as a portable terminal, but the type of the user terminal 2 is not particularly limited. For example, the user terminal 2 may be a smartphone, a personal computer, a tablet, a wearable device, or the like.

[0043] The control unit 20 includes a memory and a processor. The memory is composed of a ROM in which various programs and the like are stored, a RAM in which various programs and the like executed by the processor are stored, and the like. The various programs may include an information processing program that executes a series of information processing methods according to the present embodiment. The processor is composed of at least one of a CPU, an MPU, and a GPU, for example. The processor may be configured to load a program designated from the various programs incorporated in the storage device 21 or the ROM onto the RAM, and to execute various processes in cooperation with the RAM. In particular, the processor may execute a series of information processes described below by loading an information processing program incorporated in the storage device 21 or the ROM onto the RAM.

[0044] The storage device 21 is, for example, a NAND type flash memory, a HDD, or an SSD. The imaging unit 22 is configured to capture an image or video showing the surrounding environment of the user terminal 2. In particular, the imaging unit 22 is configured to generate image data or video data showing the surrounding environment of the user terminal 2, and includes an image sensor (for example, a CCD sensor or a CMOS sensor) and an image sensor drive processing circuit. The communication unit 23 includes a wireless communication module for communicating with an external device connected to the communication network 12. The input operation unit 24 is, for example, a touch panel arranged on top of the video display of the display unit 25, and is configured to accept an input operation of the user 3 and generate an operation signal according to the input operation of the user 3. The display unit 25 is, for example, configured by a video display and a video display circuit that drives and controls the video display.

[0045] Returning to FIG. 1, the blockchain network 10 is a P2P (Peer to Peer) type network (in other words, a distributed network) composed of multiple nodes 7. Each node 7 stores a blockchain 8. Each node 7 is directly or indirectly connected to other nodes 7. The blockchain 8 is a type of distributed ledger technology (DLT), and the blockchains 8 stored in each node 7 hold the same ledger information.

[0046] Blockchain 8 differs from a centralized database built on a server in terms of decentralization, resistance to tampering, permanence, transparency, and smart contracts. Blockchain 8 is composed of multiple blocks. Each block is linked to blocks generated before and after it. Each block has multiple transaction information and block header information. The block header information includes a timestamp, a hash value of the block header of the immediately preceding block generated immediately before it, and hash values ​​of multiple transactions. The block header information may further include a nonce value for setting the first N digits (an integer N>1) of the hash value of the block header to 0.

[0047] Specifically, each block is associated with the block generated immediately before and after it via the hash value of the block header. Therefore, in blockchain 8, if some transactions are tampered with, the hash value of the block header is changed and each block is linked in a chain by the hash values ​​of the block headers of the previous and next blocks, making it extremely difficult to tamper with the data of each block (especially the transaction information within each block).

[0048] In this embodiment, the blockchain network 10 may be a public blockchain network without an administrator, or a private blockchain network with an administrator. The consensus algorithm of the blockchain network 10 may be a PoS (Proof of Stake) type or a PoW (Proof of Work) type.

[0049] The blockchain 8 of this embodiment is a blockchain in which a smart contract is implemented. A smart contract is a program code for executing an automatic contract or automatic transaction recorded on the blockchain 8. Each node 7 executes a smart contract recorded (deployed) on the blockchain 8 and verifies the execution result of the smart contract. In this way, the smart contract can automatically execute the transaction / contract contents recorded on the blockchain 8 without the intervention of an intermediary. In this embodiment, when an NFT 6 is issued on the blockchain 8, a smart contract associated with the NFT issuance (hereinafter, an NFT issuing smart contract) is recorded on the blockchain 8. In addition, a smart contract (hereinafter, an NFT trading smart contract 11) that specifies that the NFT 6 is sold at a predetermined selling price is recorded on the blockchain 8.

[0050] As the blockchain network 10, Ethereum may be adopted, or a smart contract-implemented blockchain network other than Ethereum (for example, L1 projects such as Algorand and Solana, or L2 projects such as Polygon) may be adopted. Furthermore, a smart contract-implemented L2 project (for example, Stacks, etc.) built on the Bitcoin network may be adopted. When the blockchain network 10 is Ethereum, the EVM (Ethereum Virtual Machine) of each node 7 executes the smart contracts (in this example, the NFT issuance smart contract and the NFT trading smart contract) deployed on the blockchain 8 and verifies the execution results of the smart contracts.

[0051] IPFS 13 is a distributed storage service that operates on a P2P network. In this embodiment, as described later, information related to NFT6 may be stored on IPFS 13 as metadata. Note that information related to NFT6 may be stored on a data server connected to the communication network 12 instead of IPFS 13, or may be recorded on the blockchain 8 as on-chain information.

[0052] Next, with reference to FIG. 1, FIG. 4, and FIG. 5, the mechanism of distribution of patent rights using non-fungible tokens (NFTs) will be described below. FIG. 4 is a flowchart for explaining the mechanism of distribution of patent rights using NFTs 6. FIG. 5 is a diagram for explaining the primary distribution of NFTs 6 linked to patent rights 17 using an NFT transaction smart contract 11. As shown in FIG. 4, in step S1, the intermediary 5 requests input of user information of a user who uses a patent right distribution platform (WEB3 application) provided by the intermediary server 4. In particular, the intermediary 5 may request input of a user name, an affiliated organization name, an email address, and a wallet address as the user information of the user. For example, the intermediary server 4 transmits a WEB page constituting the patent right distribution platform (WEB3 application) to the user terminal 2a in response to an access request from the user 3a who is a patent holder. The WEB page transmitted to the user terminal 2a may be provided with an input area in which user information can be input. When the intermediary server 4 receives the user information of the user 3a from the user terminal 2a, the intermediary server 4 may update, based on the received user information of the user 3a, a user information management table constructed in the database of the intermediary server 4. In the user information management table, user information for each user (for example, user name, organization name, email address, wallet address, and information on the patent right to be sold) is stored.

[0053] Since the user 3a is a user who wishes to sell (profit) the patent right, the user may be required to input a user name, an email address, a patent number, and a wallet address as user information. The user terminal 2a may also log in to a WEB3 application (also called DApps) provided by the intermediary server 4 through authentication of a wallet address used in the browser wallet (e.g., MetaMask (registered trademark)) of the user terminal 2a. In this case, the wallet address in the browser wallet may be associated with the user's attribute information (e.g., contact information such as a user name and an email address).

[0054] In step S2, the intermediary 5 investigates whether or not there is an NFT associated with the patent right 17 held by the user 3a. For example, the intermediary 5 investigates whether or not there is an NFT equivalent to the patent right 17 by referring to table data in which multiple patent rights (patent numbers) and multiple NFTs (contract addresses, etc.) are associated with each other. If there is no NFT equivalent to the patent right 17 or if the NFT has already been burned, the process proceeds to step S3.

[0055] Next, in step S3, the intermediary 5 sends the necessary documents 15 to the user 3a, which are necessary for transferring the patent right 17 of the user 3a from the user 3a to the intermediary 5. The necessary documents 15 may include an assignment certificate or a power of attorney of the user 3a (a document proving the power of attorney of the user 3a) required for transferring the patent right 17 from the user 3a to the intermediary 5, etc. The necessary documents 15 may be sent to the user 3a by email or a messaging app. Thereafter, the user 3a writes the necessary information on the necessary documents 15, affixes a seal or signature to the necessary documents 15, and then returns the necessary documents 15 to the intermediary 5. The intermediary 5 submits the necessary documents 15 to the Japan Patent Office 16 through an agent such as a patent attorney. In this way, as shown in step (1) of FIG. 5, the patent right 17 of the user 3a is temporarily transferred from the user 3a to the intermediary 5 (step S4). In this case, the transfer of the patent right 17 from the user 3a to the intermediary 5 may be a transfer based on a trust agreement between the user 3a (trustor) and the intermediary 5 (trustee).

[0056] In step S5, the intermediary 5 issues an NFT6 associated with the patent right 17. Specifically, the intermediary server 4 distributes an issuance request transaction (an example of a first issuance request) for issuing an NFT6 associated with the patent right 17 on the blockchain 8 to the blockchain network 10 in accordance with the input operation of the intermediary 5. In this case, the intermediary server 4 distributes a series of information related to the patent right 17 to the IPFS 13 as metadata. The series of information related to the patent right 17 may include the patent number, application number, right holder (trustee), entrustor, patent expiration date, annuity payment status, licensee information / pledgee information, patent validity information, litigation / trial information, access information (URL) to the patent publication / application history, etc. of the patent right 17.

[0057] In addition, when Ethereum is adopted as the blockchain network 10, the NFT6 may be a token compatible with the ERC721 standard. The blockchain network 10 receives an issuance request transaction for the NFT6 from the intermediary server 4, and then records the NFT6 on the blockchain 8 in response to the issuance request transaction. Specifically, each node 7 constituting the blockchain network 10 records an NFT issuing smart contract associated with the NFT6 on the blockchain 8 in response to the issuance request transaction for the NFT6. The on-chain information included in the NFT issuing smart contract may include a contract address, a token ID, a wallet address of the holder, a wallet address of the NFT generator, and a metadata address (URI). In this example, the holder address of the NFT6 and the wallet address of the NFT generator are the wallet addresses of the intermediary 5. The metadata address is an address for specifying the metadata stored on the IPFS 13. The user terminal 2 is able to acquire a series of information on the patent right 17 linked to the NFT6 from the IPFS 13 based on the metadata address included in the on-chain information.

[0058] In this embodiment, each NFT issued by the intermediary 5 may be linked to a predetermined contract address. That is, the contract address of the NFT 6 may be a unique contract address linked to the intermediary 5. In this case, a third party can clearly recognize that the NFT 6 was issued by the intermediary 5 by checking the contract address of the NFT 6. In addition, when the intermediary 5 issues a new NFT using a unique contract address linked to itself, the token ID of the new NFT is changed. Meanwhile, a new contract address of the NFT may be generated every time a new NFT linked to a patent right is issued.

[0059] When Ethereum is adopted as the blockchain network 10, it is preferable that the NFT 6 is an off-chain NFT from the viewpoint of saving transaction fees (gas fees) generated by transactions related to the NFT 6. In other words, the metadata of the NFT 6 is not recorded on the blockchain 8 but is recorded outside the blockchain 8 (in this example, IPFS 13). On the other hand, the NFT 6 is not limited to being an off-chain NFT, and may be an on-chain NFT. In other words, a series of information related to the patent right 17 linked to the NFT 6 may be recorded on the blockchain 8 as on-chain information.

[0060] In step S6, the intermediary 5 generates the NFT transaction smart contract 11. Specifically, the intermediary server 4 distributes to the blockchain network 10 an issuance request transaction (an example of a second issuance request) for issuing on the blockchain 8 an NFT transaction smart contract 11 (hereinafter simply referred to as "contract 11") that specifies the sale of the NFT 6 for 100 ETH (an example of a predetermined selling price) in accordance with the input operation of the intermediary 5. After receiving the issuance request transaction from the intermediary server 4, the blockchain network 10 records the contract 11 on the blockchain 8 in response to the issuance request transaction. More specifically, each node 7 constituting the blockchain network 10 records the contract 11 on the blockchain 8 in response to the issuance request transaction.

[0061] In step S7, the intermediary 5 transfers the NFT 6 to the contract 11 (see step (2) in FIG. 5). Specifically, the intermediary server 4 distributes a change request transaction to the blockchain network 10 to change the owner of the NFT 6 from the intermediary 5 (wallet address of the intermediary 5) to the contract 11 (contract address of the contract 11). After receiving the issuance request transaction from the intermediary server 4, the blockchain network 10 records information indicating that the owner of the NFT 6 has been changed from the intermediary 5 to the contract 11 in response to the issuance request transaction on the blockchain 8. Note that in the description of this embodiment, the owner of the NFT 6 has been changed from the intermediary 5 to the contract 11, but this embodiment is not limited to this. For example, the NFT 6 may be automatically transferred from the intermediary 5 to the NFT purchaser when the contract 11 is executed, with the owner of the NFT 6 being maintained in the intermediary 5. In this regard, intermediary 5 may pre-approve a contract providing that NFT 6 will be automatically transferred to the NFT purchaser upon execution of contract 11.

[0062] In step S8, the intermediary server 4 uploads NFT sales information 100 indicating sales information of the NFT 6 linked to the patent right 17 onto the patent right distribution platform (WEB3 application) (see FIG. 6). Specifically, the intermediary server 4 transmits a web page indicating the NFT sales information 100 to the user terminal 2b. The user terminal 2b displays the NFT sales information 100 on its own browser in response to the received web page. In the example of FIG. 6, the NFT sales information 100 indicates that the NFT 6 is being sold for 100 ETH (200,000 US dollars). The NFT sales information 100 may also include a series of information related to the patent right 17 and information related to the NFT 6 (contract address and token ID).

[0063] In step S9, the user 3b, who is the purchaser, remits cryptocurrency equivalent to the selling price of 100 ETH to the contract 11 in order to purchase the NFT6 linked to the patent right 17. Specifically, the user terminal 2b first accepts the input operation of the user 3b on the user terminal 2b. For example, the user terminal 2b launches a web wallet (e.g., MetaMask, etc.) not shown in the figure in response to the input operation of the user 3b on the purchase button 120. Thereafter, the user terminal 2b delivers a remittance request transaction (an example of a remittance request) for remitting 100 ETH of cryptocurrency to the contract 11 to the blockchain network 10 in accordance with the remittance operation of the user 3b on the web wallet (see step (3) in FIG. 5). Note that, before the processing of step S9, the user terminal 2b transmits the user information of the user 3b to the intermediary server 4 and logs in to the WEB3 application provided by the intermediary server 4 through authentication of the wallet address of the browser wallet.

[0064] In step S10, the contract 11 transfers the NFT6 to the user 3b, who is the purchaser (see step (4) in FIG. 5). Next, in step S11, the contract 11 remits 95 ETH of cryptocurrency, which is 95% of the selling price of the NFT6, 100 ETH, to the user 3a, who is the patent holder (see step (5) in FIG. 5), and remits the remaining 5% of the cryptocurrency, 5 ETH, to the intermediary 5 as an intermediary fee (see step (6) in FIG. 5). More specifically, the blockchain network 10 calls the contract 11 in response to a remittance request delivered from the user terminal 2b, thereby recording information on the blockchain 8 indicating that the owner of the NFT6 has been changed to the user 3b. In addition, the blockchain network 10 records information on the blockchain 8 indicating that the cryptocurrency, 95 ETH, which is the amount obtained by multiplying the selling price of 100 ETH by 95%, has been remitted to the user 3a. Furthermore, the blockchain network 10 records on the blockchain 8 information indicating that the cryptocurrency 5 ETH, which is the amount obtained by multiplying the sales price of 100 ETH by a rate of 5%, has been transferred to the intermediary 5. Note that in this example, an amount of 5% of the sales price of the NFT6 is transferred to the intermediary 5 as the intermediary fee, but the percentage of the intermediary fee is not limited to 5%. The percentage of the intermediary fee may vary depending on the sales price of the NFT6 (patent right). For example, the percentage of the intermediary fee may be gradually decreased as the sales price increases.

[0065] Alternatively, 95 ETH of cryptocurrency, calculated by deducting 5 ETH (an example of a predetermined amount) from the amount equivalent to the selling price of 100 ETH, may be transferred to user 3a, and 5 ETH may also be transferred to intermediary 5. In this case, a fixed amount of intermediary fee (5 ETH in this example) is transferred to intermediary 5 regardless of the selling price of the NFT 6.

[0066] Furthermore, depending on the circumstances, the brokerage fee may be free. In this regard, in the case where a subscription method is adopted as a usage fee for the distribution platform, the percentage of the brokerage fee incurred when buying and selling NFTs may be 0%. In this way, when the brokerage fee is free, an amount equivalent to the selling price of 100 ETH may be transferred to the user 3a. In addition, the user 3b shall bear the gas fee required for a series of transactions in addition to 100 ETH equivalent to the selling price of the NFT6. In this example, ETH is used as the cryptocurrency, but other tokens based on the ERC-20 standard (e.g., USDT, USDC, JPYC, etc.) may be used as the settlement currency.

[0067] In step S12, the intermediary 5 receives the NFT6 from the user 3b who is the purchaser (see step (7) in FIG. 5), and then burns the NFT6 received from the user 3b (see step (8) in FIG. 5). Specifically, first, the user terminal 2b distributes a change request transaction to change the owner of the NFT6 from the user 3b to the intermediary 5 to the blockchain network 10 in response to an input operation of the user 3b on the user terminal 2b. Next, the blockchain network 10 receives the change request transaction from the user terminal 2b, and records information indicating that the owner of the NFT6 has been changed from the user 3b to the intermediary 5 in response to the change request transaction on the blockchain 8. After that, the intermediary 5 sends the NFT6 to an uncontrollable wallet address in order to burn the NFT6. When the NFT6 is sent to an uncontrollable wallet address, the private key associated with the wallet address is not known to anyone, and it is no longer possible to send the NFT6 to another wallet address.

[0068] Thereafter, the intermediary 5 transmits the necessary documents 15a required for the transfer registration of the patent right 17 from the intermediary 5 to the user 3b via e-mail or the like to the user 3b (see step (9) in FIG. 5). The necessary documents 15a may include an assignment certificate and a power of attorney of the user 3b (document proving the power of attorney of the user 3b) required for the transfer of the patent right 17 from the intermediary 5 to the user 3b. In step S13, the user 3b enters the necessary information in the necessary documents 15a, affixes a seal or signature to the necessary documents 15a, and returns the necessary documents 15a to the intermediary 5. In step S14, the intermediary 5 submits the necessary documents 15a to the Japan Patent Office 16 through an agent such as a patent attorney (see step (10) in FIG. 5).

[0069] In this way, according to this embodiment, it is possible to realize smooth and secure transactions of patent right 17 through the buying and selling of NFT 6 associated with patent right 17 via contract 11.

[0070] In addition, because NFT 6 is associated with attribute information, etc., of patent right 17, user 3b, who is a prospective purchaser of patent right 17, can purchase NFT 6 linked to patent right 17 with peace of mind by checking attribute information, etc., of patent right 17 described in the metadata of NFT 6. Furthermore, because intermediary 5, who is the generator of NFT 6, actually owns patent right 17 linked to NFT 6, user 3b, who is a prospective purchaser, can purchase patent right 17 through NFT 6 with peace of mind.

[0071] Next, with reference to FIG. 1 and FIG. 7, a case where a user 3b who purchased an NFT6 on the patent right distribution platform resells the NFT6 to a user 3c will be described below. FIG. 7 is a diagram for explaining the secondary distribution of an NFT6 linked to a patent right 17 using an NFT trading smart contract 11a (hereinafter simply referred to as "contract 11a"). In this patent right distribution platform (WEB3 application), the patent right 17 can be traded via the NFT6, and the NFT6 can be freely traded between investors via the contract 11a. In this way, this platform has a great advantage in that the patent right 17 linked to the NFT6 can be freely traded borderlessly and without the presence of an intermediary 5 through the contract 11a. On the other hand, when finally converting the NFT6 into the patent right 17, the NFT6 needs to be sent to the intermediary 5, and the intermediary 5 needs to carry out a transfer registration procedure for the patent right.

[0072] As shown in FIG. 7, the user 3b generates an NFT transaction smart contract 11a. Specifically, the user terminal 2b distributes to the blockchain network 10 an issuance request transaction for issuing the contract 11a, which specifies that the NFT 6 is to be sold for 120 ETH (an example of a predetermined selling price), on the blockchain 8, in accordance with the input operation of the user 3b. After receiving the issuance request transaction from the user terminal 2b, the blockchain network 10 records the contract 11a on the blockchain 8 in response to the issuance request transaction. More specifically, each node 7 constituting the blockchain network 10 records the contract 11a on the blockchain 8 in response to the issuance request transaction.

[0073] Next, in step (1) of FIG. 7, the user 3b transfers the NFT6 to the contract 11a. Specifically, the user 3b delivers a change request transaction to change the owner of the NFT6 from the user 3b to the contract 11a to the blockchain network 10. After receiving the change request transaction from the user terminal 2b, the blockchain network 10 records information indicating that the owner of the NFT6 has been changed from the user 3b to the contract 11a in response to the change request transaction on the blockchain 8. Note that in the description of this embodiment, the owner of the NFT6 has been changed from the user 3b to the contract 11a, but this embodiment is not limited to this. For example, the NFT6 may be automatically transferred from the user 3b to the NFT purchaser when the contract 11a is executed, with the owner of the NFT6 being maintained by the user 3b. In this regard, the user 3b may approve in advance a contract that specifies that the NFT6 is automatically transferred from the user 3b to the NFT purchaser when the contract 11a is executed.

[0074] Next, the intermediary server 4 uploads NFT sales information indicating sales information of the NFT 6 linked to the patent right 17 onto the patent right distribution platform (WEB3 application). Specifically, the intermediary server 4 transmits a web page indicating the NFT sales information to the user terminal of the user 3c (not shown). The user terminal of the user 3c (hereinafter referred to as "user terminal 2c") displays the NFT sales information on a browser in accordance with the received web page. The user terminal 2c is assumed to have the same hardware configuration as the user terminal 2 shown in FIG. 2.

[0075] In step (2) of FIG. 7, the purchaser, user 3c, transfers cryptocurrency equivalent to the selling price of 120 ETH to the contract 11a in order to purchase NFT6 linked to patent right 17. Specifically, the user terminal 2c first accepts an input operation of the user 3c to the user terminal 2c. For example, the user terminal 2c launches a web wallet (e.g., MetaMask, etc.) (not shown) in response to an input operation of the user 3c to a purchase button. After that, the user terminal 2c distributes a remittance request transaction to transfer 120 ETH of cryptocurrency to the contract 11a to the blockchain network 10 in accordance with the remittance operation of the user 3c to the web wallet.

[0076] In step (3) of FIG. 7, the contract 11a transfers the NFT6 to the user 3c, who is the purchaser. Next, in step (4) of FIG. 7, the contract 11a transfers cryptocurrency 114ETH, which is 95% of the selling price of the NFT6, 120ETH, to the user 3b, who is the owner of the NFT6, and transfers the remaining 5% of the cryptocurrency, 6ETH, to the intermediary 5 as an intermediary fee (see step (5) of FIG. 5). More specifically, the blockchain network 10 records information on the blockchain 8 indicating that the owner of the NFT6 has been changed to the user 3c by calling the contract 11a in response to a remittance request delivered from the user terminal 2c. In addition, the blockchain network 10 records information on the blockchain 8 indicating that cryptocurrency 114ETH, which is the amount obtained by multiplying the selling price of 120ETH by 95%, has been remitted to the user 3b. Furthermore, the blockchain network 10 records information on the blockchain 8 indicating that 6 ETH of cryptocurrency, an amount obtained by multiplying the selling price of 120 ETH by a rate of 5%, has been transferred to the intermediary 5.

[0077] Also, cryptocurrency 115 ETH, which is an amount obtained by deducting 5 ETH (an example of a predetermined amount) from the amount equivalent to the selling price of 120 ETH, may be transferred to the user 3b, and 5 ETH may be transferred to the intermediary 5. In this case, a fixed amount of intermediary fee (5 ETH in this example) is transferred to the intermediary 5 regardless of the selling price of the NFT6. Furthermore, the intermediary fee may be free depending on the situation. In this regard, when a subscription method is adopted as a usage fee for the distribution platform, the percentage of the intermediary fee generated when buying and selling NFTs may be 0%. In this way, when the intermediary fee is free, an amount equivalent to the selling price of 120 ETH may be transferred to the user 3b. Also, the user 3c is assumed to bear the gas fee required for a series of transactions in addition to 120 ETH equivalent to the selling price of the NFT6. In this example, ETH is used as the cryptocurrency, but other tokens based on the ERC-20 standard (e.g., USDT, USDC, JPYC, etc.) may be used as the settlement currency.

[0078] In step (6) of FIG. 7, the intermediary 5 receives the NFT 6 from the user 3c who is the purchaser, and then burns the NFT 6 received from the user 3c (see step (7) of FIG. 7). Specifically, first, the user terminal 2c distributes a change request transaction to change the owner of the NFT 6 from the user 3c to the intermediary 5 to the blockchain network 10 in response to an input operation of the user 3c on the user terminal 2c. Next, the blockchain network 10 receives the change request transaction from the user terminal 2c, and records information indicating that the owner of the NFT 6 has been changed from the user 3c to the intermediary 5 in response to the change request transaction on the blockchain 8. After that, the intermediary 5 sends the NFT 6 to an uncontrollable wallet address (a wallet address whose private key is not known to anyone) in order to burn the NFT 6.

[0079] Thereafter, the intermediary 5 transmits the necessary documents 15b required for the transfer registration of the patent right 17 from the intermediary 5 to the user 3c via e-mail or the like to the user 3c (see step (8) in FIG. 7). The necessary documents 15b may include an assignment certificate or a power of attorney (document proving the power of attorney of the user 3c) of the user 3c required for the transfer of the patent right 17 from the intermediary 5 to the user 3c. The user 3c enters the necessary information in the necessary documents 15b, affixes a seal or signature to the necessary documents 15b, and returns the necessary documents 15b to the intermediary 5. The intermediary 5 then submits the necessary documents 15a to the Patent Office 16 through an agent such as a patent attorney. As a result, the patent right 17 is transferred from the intermediary 5 to the user 3c (see step (9) in FIG. 7).

[0080] Thus, according to the present embodiment, it is possible to realize smooth and safe transactions of the patent right 17 through the buying and selling of the NFT 6 associated with the patent right 17 via the contract 11a. Furthermore, it is possible to freely and safely trade the patent right 17 linked to the NFT 6 in a borderless manner and without the presence of the intermediary 5 through the contract 11a. In particular, it is possible to provide a patent right distribution platform that is attractive to global investors who buy and sell the patent right 17 for investment or speculative purposes.

[0081] Although the embodiment of the present invention has been described above, the technical scope of the present invention should not be interpreted as being limited by the description of the embodiment. The embodiment is an example, and it is understood by those skilled in the art that various modifications of the embodiment are possible within the scope of the invention described in the claims. The technical scope of the present invention should be determined based on the scope of the invention described in the claims and its equivalents. [Explanation of symbols]
