Description

Technical Field

[0001] The present invention relates to the technical field of blockchain, and in particular to a blockchain-based patent securitization management system and method. Background Art

[0002] This section aims to provide background or context for the embodiments of the present invention described in the claims. The descriptions herein are not admitted to be prior art merely because they are included in this section.

[0003] As assets, patents have extremely poor liquidity. The price of a single patent may be very high, the transaction procedures are very complicated, it is difficult to price through mechanisms such as market makers, and the return period of patents may be very long. They are concentratedly held by one party and cannot share risks.

[0004] Securitization under the traditional model is a method to solve the problems of poor asset liquidity and long return periods. However, different from the issuance of shares by a company, there are a large number of patents, which are difficult to supervise, and there is a lack of a relevant unified trading platform. At the same time, how to implement an efficient patent management solution after securitization is also a difficult problem.

[0005] Currently, it has been proposed that the transparency of the blockchain can be used for securitization supervision. Based on the blockchain, these indivisible patent rights are securitized and then traded on the exchange. By virtue of the public transparency of the blockchain, the trading risks of users are reduced, and thus the trading experience of users is improved. For example, tokens corresponding to the value of the patent rights are issued and sold on the first blockchain network through the patent right numbers and values. Subsequently, based on the holding shares of the patent right holders, the tokens are distributed to the patent holders in proportion. After determining the first income of the patent right and the second blockchain addresses of the token holders respectively, the license income of the patent is sent to the corresponding second blockchain addresses of each owner according to the corresponding proportion.

[0006] The above technical solution realizes the conversion of electronic assets into securitized on-chain assets (securitizing patent rights). However, different from the securities market in the traditional financial world, some electronic assets need to maintain their integrity for use. When a certain buyer attempts to repurchase all the tokens of a certain patent right in full, the buyer may encounter the situation that some token holders maliciously take advantage of the nature that the patent needs to maintain its integrity to maliciously jack up the price, which hinders the buyer's acquisition action. This phenomenon will ultimately reduce the buyer's willingness to purchase patent right tokens.

[0007] Similar to the securitization under the traditional model, this securitization method does not solve the problems of a large number of patent rights, difficult supervision, and the lack of a relevant unified trading platform. After securitization, since the income of each buyer exists on different second blockchain networks, there is a lack of an efficient patent management solution, such as the pricing of patent securitization repurchase. Summary of the Invention

[0008] An embodiment of the present invention provides a blockchain-based patent securitization management system for solving the problems of patent securitization repurchase pricing and management. The system includes:

[0009] A control node and multiple user nodes, where the control node and user nodes are nodes on the blockchain network; among them,

[0010] User nodes are used to securitize a complete patent into multiple patent securities based on a smart contract;

[0011] The control node is used to determine whether there is a user node that meets the repurchase trigger condition. If so, the user node that meets the repurchase trigger condition is determined as the first party, and other user nodes are determined as the second party. Based on the smart contract, an auction process is executed for the first party and the second party; if not, based on the smart contract, a free trading process is executed for all user nodes.

[0012] An embodiment of the present invention also provides a blockchain-based patent securitization management method, which is applied to the control node. Among them, the control node is a node on the blockchain network, and the method includes:

[0013] Determine whether there is a user node that meets the repurchase trigger condition; among them, the user node is a node on the blockchain network and is used to securitize a complete patent into multiple patent securities based on a smart contract;

[0014] If so, the user node that meets the repurchase trigger condition is determined as the first party, and other user nodes are determined as the second party. Based on the smart contract, an auction process is executed for the first party and the second party;

[0015] If not, based on the smart contract, a free trading process is executed for all user nodes.

[0016] An embodiment of the present invention also provides a computer device, which includes a memory, a processor, and a computer program stored on the memory and executable on the processor. When the processor executes the computer program, the above method is implemented.

[0017] An embodiment of the present invention also provides a computer-readable storage medium, which stores a computer program. When the computer program is executed by a processor, the above blockchain-based patent securitization management method is implemented.

[0018] An embodiment of the present invention also provides a computer program product, which includes a computer program. When the computer program is executed by a processor, the above blockchain-based patent securitization management method is implemented.

[0019] In an embodiment of the present invention, the control node and the user node are nodes on a blockchain network; among them, the user node is used to securitize a complete patent into multiple patent securities based on a smart contract; the control node is used to determine whether there is a user node that meets the repurchase trigger condition. If so, it determines the user node that meets the repurchase trigger condition as the first party and other user nodes as the second party, and executes an auction process for the first party and the second party based on the smart contract; if not, it executes a free trading process for all user nodes based on the smart contract. Compared with the prior art in which tokens are distributed to patent holders in proportion based on the holding shares of the patent holders, by determining whether the user node meets the repurchase trigger condition, and thus determining whether to enter the auction process or the repurchase process, the repurchase pricing of patent securities can be realized, and the risk problems caused by poor liquidity and long return periods of patents are solved.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will further describe the embodiments of the present invention in detail with reference to the drawings. Herein, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but not to limit the present invention.

[0027] Figure 1Schematic diagram of the blockchain-based patent securitization management system in the embodiments of the present invention Figure 1 , including:

[0028] A control node 101 and multiple user nodes 102, where the control node 101 and the user nodes 102 are nodes on the blockchain network; among them,

[0029] The user node 101 is used to securitize a complete patent into multiple patent securities based on a smart contract;

[0030] The control node 102 is used to determine whether there is a user node that meets the repurchase trigger condition. If so, it determines the user node that meets the repurchase trigger condition as the first party, and the other user nodes as the second party, and executes an auction process for the first party and the second party based on the smart contract; if not, it executes a free trading process for all user nodes based on the smart contract.

[0031] Specifically in implementation, the control node needs to maintain the consensus of the blockchain system.

[0032] In one embodiment, the repurchase trigger condition is that the user node has a repurchase intention, and the share of the patent securities of the user node is within a set range.

[0033] In the above embodiment, the set range can be greater than 50% and less than 100%. The advantages and significance of this set range are as follows: 1) Similar to the traditional financial market, only when a certain buyer holds the majority of the assets can he have the right to use the assets, called the seller, and when the trigger threshold is 50% or above, it can be ensured that only one buyer can trigger the repurchase, avoiding the situation of multiple sellers; 2) When using a parameter greater than 50% as the repurchase threshold, it can be avoided that all the patent securities held by all buyers fall below the threshold value during the repurchase process of two buyers, abnormally terminating the repurchase.

[0034] In one embodiment, the user node is specifically used for:

[0035] After receiving the bid notice through the blockchain network, make a bid according to the share of the patent securities in the bid notice, and send the bid to the blockchain network;

[0036] The control node is specifically used for:

[0037] Execute the auction process for the first party and the second party according to the following steps:

[0038] Send a bid notice to the blockchain network;

[0039] Obtain the bids of the first party and the second party through the blockchain network;

[0040] When the bid of the second party is higher than that of the first party, based on the bids of the first party and the second party, calculate the transaction price according to a preset rule, add the transaction price to the first party, and add all the patent security shares of the first party to the second party;

[0041] When the bid of the first party is higher than that of the second party, based on the bids of the first party and the second party, calculate the transaction price according to a preset rule, add the transaction price to the second party, and add all the patent security shares of the second party to the first party.

[0042] In the above embodiments, the preset rule can be determined according to the actual situation. For example, when the bid of the second party is higher than that of the first party, the preset rule is to calculate the mid-price of the bids of the first party and the second party; when the bid of the first party is higher than that of the second party, the preset rule is lower than the mid-price of the bids of the first party and the second party.

[0043] The above auction process is a single-round auction. At the end of each single-round auction, the control node will check whether the buyback trigger condition is met. If so, conduct the next round of auction; if not, conduct free trading.

[0044] The advantage of this auction scenario is that under this design, the benefits obtained by the first party and the second party when bidding according to their true psychological prices for patent securities are always non-negative, that is, the benefits of honest bidding are always non-negative. This scenario design can make both the first party and the second party willing to bid honestly. At the same time, users who maliciously bid up the price will be punished by the design of forced buyback. The above auction process has convergence, and the proof is as follows:

[0045] In a single-round game, there is a Bayesian Stackelberg equilibrium in each Stackelberg game (the game design used in the embodiments of the present invention, and there are differences in the action order of all users in the game). Moreover, each Bayesian Stackelberg equilibrium is a Nash equilibrium. According to mathematical analysis, the best corresponding bid of each seller for the buyer's bid in each round can be obtained. When the seller's psychological price vi is greater than the buyer's psychological price v0, the best bid of the seller is v0; otherwise, the best bid of the seller is v0 + 1 (the 1 here is an adjustable parameter used to represent a very small value). Through mathematical analysis and proof, the best reply price of the buyer for the specific bid pi of the seller can be obtained as follows: when pi > v0 + 1, bid pi - 1; otherwise, bid pi. The conclusion drawn from this analysis is that the benefits are always non-negative when all users bid honestly: that is, all users will have the willingness to bid honestly, so that there is no malicious bidding in this auction process.

[0046] Figure 2 Schematic of the blockchain-based patent securitization management system in the embodiments of the present invention Figure 2 In one embodiment, the system further includes a permission management node 103, and the permission management node is a node on the blockchain network;

[0047] The user node is further configured to: set the corresponding permission management node;

[0048] The control node is further configured to:

[0049] After entering the auction process, if no bid is received from the second party within the set time limit, obtain the bid sent by the corresponding permission management node of the second party through the blockchain network.

[0050] The above embodiments are strategies designed for users who are unwilling or forget to place a bid to ensure the progress of the transaction. In one embodiment, the user node is further configured to: set the acquisition price of the patent securities when first obtaining the patent securities;

[0051] The control node is further configured to:

[0052] After entering the auction process, if no bid is received from the second party within the set time limit, obtain the acquisition price of the patent securities set by the second party.

[0053] The above embodiments are also strategies designed for users who are unwilling or forget to place a bid to ensure the progress of the transaction.

[0054] In one embodiment, the user node is further configured to: when holding all the patent security shares of a patent, integrate all the patent securities into a complete patent.

[0055] Figure 3 Schematic of the blockchain-based patent securitization management system in the embodiments of the present invention Figure 3 , in one embodiment, the system includes a supervision node 104 for supervising the free trading process and the auction process; when the free trading process or the auction process is abnormal, sending a termination instruction to the blockchain network;

[0056] The control node is further configured to: after receiving the termination instruction through the blockchain network, terminate the free trading process or the auction process.

[0057] The above supervision mechanism enables the supervision department on the supervision node to more conveniently utilize the consistency and immutability of the blockchain history to supervise patent securitization.

[0058] In one embodiment, the user node is further configured to: before securitizing a complete patent into multiple patent securities, send a securitization request to the blockchain network; after receiving the permission securitization notice through the blockchain network, securitize the complete patent into multiple patent securities;

[0059] The supervision node is further configured to: after receiving the securitization request through the blockchain network, review the securitization request, and after passing the review, send a permission securitization notice to the blockchain network.

[0060] Similarly, the above regulatory mechanism enables the regulatory departments on the regulatory nodes to more conveniently utilize the consistency and immutability of the blockchain history to supervise patent securitization. It should be noted that the above process of reviewing securitization requests can be executed by the regulatory part or automatically executed by a custom program. For example, the process of the custom program is as follows: judging whether a patent can be securitized according to the patent type or classification number, and related variations all fall within the protection scope of the present invention.

[0061] In an embodiment, the control node is further configured to: send a repurchase request to the blockchain network before executing the auction process; execute the auction process after receiving the permission to repurchase notice through the blockchain network;

[0062] The regulatory node is further configured to: review the repurchase request after receiving the repurchase request through the blockchain network, and send a permission to repurchase notice to the blockchain network after the review is passed.

[0063] Similarly, the above regulatory mechanism enables the regulatory departments on the regulatory nodes to more conveniently utilize the consistency and immutability of the blockchain history to supervise patent securitization.

[0064] In an embodiment, the control node is further configured to: send a voting notice to the blockchain network based on operation requirements; count the voting results through the blockchain network and send them to the blockchain network;

[0065] The user node is further configured to: vote after receiving the voting notice through the blockchain network and send it to the blockchain network.

[0066] The above design enables, for the securitized patents, if some operations are needed (such as whether to authorize certain enterprises), to vote through a smart contract, and it can be specified as one vote per share or different votes per share before securitization, so as to give a flexible operation space for different maintenance operations.

[0067] In summary, the blockchain-based patent securitization management system proposed in the embodiments of the present invention has the following beneficial effects:

[0068] First, by judging whether the user node meets the repurchase trigger condition, and thus judging whether to enter the auction process or the repurchase process, it is possible to realize the pricing of patent securitization repurchase, and solve the risk problems caused by the poor liquidity and long return period of patents.

[0069] Second, the strategy designed for users who are unwilling or forget to bid can ensure the progress of the transaction.

[0070] Third, it enables the regulatory departments on the regulatory nodes to more conveniently utilize the consistency and immutability of the blockchain history to supervise patent securitization.

[0071] Fourth, give flexible operation space for different maintenance operations.
