[0017] 1. A new service that promotes the circulation of products within the market The applicant proposes a new service that promotes the circulation of goods in a market. This new service is intended to allow goods to be passed to any user and circulated in the market without remaining with a specific user. In this new service, goods purchased by a user are immediately put up for sale on a platform for selling, purchasing, and repairing goods, and the user can wait for a purchase offer from another user for the put-up goods. The user can use the put-up goods while waiting for a purchase offer from another user. This allows the user to have a unique experience of "using a goods while waiting for an opportunity to sell the goods." When a user receives a purchase offer from another user and agrees to the contents of the purchase offer from the other user, the goods are purchased by the other user. The goods purchased by the other user are put up for sale again on the platform, and the other user can wait for a purchase offer from yet another user for the goods, and can use the goods while waiting for a purchase offer from yet another user. This allows goods to be put up for sale in the market semi-permanently. What one user does not need is often necessary for another, and it is possible to circulate what one user does not need to users who need it. In this way, this new service provides a mechanism for "selling products while using them" and a mechanism for "products that change owners but remain listed on the market, ensuring that the products will reach those who need them forever," which promotes the circulation of products within the market.

[0018] Also, there are potential users who have no intention of selling an item, but who start considering selling the item after learning of the intention of others to purchase the item. In this new service, while a user is using the item, the item is in a state of waiting for a purchase offer from another user, so the user can receive a purchase offer from another user regardless of the user's intention to sell the item. Therefore, this new service can expose such potential users. This can increase the number of users who sell unwanted items, and can increase the number of items circulating in the market, thus further contributing to promoting the circulation of items in the market.

[0019] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0020] Figure 1 is a diagram showing an example of a new service that promotes the circulation of products within a market. Each step shown in Figure 1 will be explained below.

[0021] Step S1: A user X purchases or repairs a product P on a given platform α. Here, the product is any object that can be bought and sold. For example, the product may include, but is not limited to, a watch, a bag, a shoe, etc.

[0022] Step S2: In response to the user X purchasing or repairing the product P, the product P is put up for sale on the predetermined platform α. This allows other users to check detailed information of the product P put up for sale on the predetermined platform α. While the product P is put up for sale on the predetermined platform α, the user X can continue to use the product P. The listing of the product P may be executed automatically in response to the user X purchasing or repairing the product P, or may be executed after approval from the user X. It is not necessary for the user X to input information about the product P in order to list the product P on the predetermined platform α.

[0023] Step S3: A user Y who wishes to purchase a product P on a given platform α can make an offer to purchase the product P to a user X. At this time, the user Y presents to the user X the price at which the user wishes to purchase the product P.

[0024] If User X cannot accept the proposed purchase price for Product P, User X can either present User Y with the desired selling price for Product P or cancel (i.e., withdraw) the sale of Product P.

[0025] Step S4: When user X accepts the price that user Y desires to purchase product P, or when user Y accepts the price that user X desires to sell product P, the sale of product P is completed.

[0026] When the sale of the product P is completed, the user X ships the product P to a management company that operates and manages a given platform α or to the warehouse of the management company. When the management company receives the product P from the user X, it inspects the product P (i.e., checks the current state of the product P). If the rank corresponding to the current state of the product P is lower than the rank at the time of listing the product P (i.e., if the rank corresponding to the state of the product P is lower than the rank corresponding to the state of the product P at the time of listing the product P by the user X due to the user X's use of the product P), it identifies a fair price corresponding to the current state of the product P and notifies both the user X and the user Y of the current state of the product P and its fair price. In response to receiving the notification of the fair price of the product P, the user X responds whether or not he agrees to sell the product P at the fair price, and in response to receiving the notification of the fair price of the product P, the user Y responds whether or not he agrees to purchase the product P at the fair price. If both User X and User Y agree to the sale and purchase of Product P at the fair price, the sale and purchase of Product P is concluded once again, and the management company ships Product P to User Y and executes the settlement process at the fair price of Product P. If the management company receives a response from either User X or User Y that they do not agree to the sale or purchase of Product P at the fair price, the management company notifies User X and User Y that the sale and purchase of Product P has not been concluded.

[0027] When the sale of the product P is completed, the product P purchased by the user Y is relisted on the specified platform α for sale of the product P. This allows the product P to continue to be listed on the specified platform α semi-permanently, and other users can check detailed information of the product P listed on the specified platform α on the specified platform α. While the product P is listed on the specified platform α, the user Y can continue to use the product P. The relisting of the product P may be performed automatically in response to the purchase procedure of the product P by the user Y, or may be performed after the user Y gives consent. It is not necessary for the user Y to input information about the product P in order to relist the product P on the specified platform α.

[0028] In the embodiment shown in Fig. 1, an example is described in which a product purchased by a user X on a predetermined platform α is put up for sale on the predetermined platform α, but the present invention is not limited to this. The product put up for sale on the predetermined platform α may be any product. For example, the product put up for sale on the predetermined platform α may be an item owned by the user X.

[0029] 2. Screen transitions displayed on the user device 2A shows a screen 210 displayed on a user device. A user device refers to any device used by a user. Examples of user devices include, but are not limited to, a tablet terminal or a smartphone.

[0030] The screen 210 is an example of a screen for a buyer to view detailed information of a product exhibited on a given platform α. The screen 210 is a screen displayed on a user device operated by a buyer. In the embodiment shown in FIG. 2A, the screen 210 includes a name area 211 for displaying the name of the exhibited product, an image area 212 for displaying an image of the exhibited product, a rank area 213 for displaying the rank of the exhibited product, a description area 214 for displaying a detailed description of the exhibited product, a recommended purchase price area 215 for displaying a recommended purchase price of the exhibited product, a price reference information area 216 for displaying information that serves as a reference for the purchase price of the exhibited product, a desired purchase price area 217 for inputting a desired purchase price of the exhibited product, and a purchase offer area 218 for making a purchase offer to the current owner (i.e., the seller) of the exhibited product. The desired purchase price area 217 is configured to allow a numerical value to be input. The purchase offer area 218 is configured to allow selection.

[0031] In the embodiment shown in Fig. 2A, "ROLEX DAYTONA" is displayed in the name area 211, "S" is displayed in the rank area 213, and "xxxxxx yen to yyyyyy yen" is displayed in the recommended purchase price area 215. That is, in the embodiment shown in Fig. 2A, the screen 210 displays the product page of the "ROLEX DAYTONA" with a rank of S, and the recommended purchase price of the "ROLEX DAYTONA" with a rank of S is set to be "xxxxxx yen to yyyyyy yen."

[0032] The price reference information area 216 may display, for example, information showing the trends in the transaction prices of an S-ranked "Rolex Daytona" within a specified period in the past (e.g., within six months, within a year, within three years, etc.), information showing the history of purchase offers to the current owner (i.e., the seller) of the S-ranked "Rolex Daytona" being listed (e.g., information showing the desired purchase price, the date of the purchase offer, and whether the sale was successful), and information showing the NFT history (e.g., the names and user IDs of past owners, the selling amount, and the selling date).

[0033] In the embodiment shown in Fig. 2A, the selling price of the product P is not displayed on the screen 210. This is because the selling price of the product P is not set. In other words, the buyer can propose a purchase price to the seller by inputting a desired purchase price in the desired purchase price area 217.

[0034] The suggested purchase price field 217 may be configured to not allow a value below the minimum recommended purchase price (i.e., xxxxxx yen in the embodiment shown in FIG. 2A) to be entered. This prevents the seller from being offered a low suggested purchase price that is out of proportion to the product being offered. The suggested purchase price field 217 is also configured to allow a value above the maximum recommended purchase price (i.e., yyyyyy yen in the embodiment shown in FIG. 2A).

[0035] When the buyer inputs a desired purchase price in the desired purchase price area 217 and selects the purchase offer area 218, the seller is notified that the buyer wishes to purchase at the input desired purchase price.

[0036] Note that the screen 210 in Fig. 2A may further include an area (not shown) for inputting comments from the buyer. Also, the image displayed in the image area 212 of the screen 210 in Fig. 2A may be a predetermined image prepared by a management company that operates and manages a predetermined platform α, or may be an image taken by the seller.

The selling area 227, the price negotiation area 228, and the cancellation area 229 are configured to be selectable.

[0039] In the embodiment shown in Fig. 2B, the name area 221 displays "ROLEX DAYTONA", the rank area 223 displays "S", the recommended purchase price area 224 displays "xxxxxx yen to yyyyyy yen", and the desired purchase price area 225 displays "xxxxxx yen". That is, in the embodiment shown in Fig. 2B, the screen 220 displays a purchase offer notification for a "ROLEX DAYTONA" of rank S with a recommended purchase price of "xxxxxx yen to yyyyyy yen", and the desired purchase price is "xxxxxx yen".

[0040] The price reference information area 226 may display, for example, information showing the trends in transaction prices for an S-ranked Rolex Daytona within a specified period of time in the past (e.g., within six months, within one year, within three years, etc.).

[0041] If the seller agrees to sell the product at the desired purchase price displayed in the desired purchase price area 225, the seller selects the sale area 227, and the screen transitions from screen 220 to a screen (not shown) for proceeding with the sale procedure. If the seller is willing to sell the product to the buyer but wishes to negotiate the sale price with the buyer, the seller selects the price negotiation area 228, and the screen transitions from screen 220 to a screen for negotiating the sale price of the product (i.e., screen 230, described below with reference to FIG. 2C). If the seller wishes to reject the sale of the product, the cancel area 229 is selected, and the buyer is notified that the sale of the product has not been concluded.

[0042] The screen 220 of FIG. 2B may further display a deadline for replying to the purchase offer from the buyer (i.e., a deadline for selecting any one of the selling area 227, the price negotiation area 228, and the cancellation area 229). The screen 220 of FIG. 2B may further display information indicating the stages of the status until the purchase of the product is completed (e.g., the negotiation stage, the delivery stage, the inspection stage, the payment stage, and the completion stage) and the current status. The screen 220 of FIG. 2B may further display the net profit, the service usage fee, and the consumption tax when the product P is sold at the buyer's desired purchase price, in addition to the buyer's desired purchase price. The screen 220 of FIG. 2B may further display the seller's desired selling price set in advance.

On the platform α, it may be possible to request a management company to repair the product.

[0067] Step S502: An input from a user X indicating that the user X wishes to purchase or repair a product P on the platform α is received. The input from the user X is received, for example, from a user device 3201 operated by the user X. The input from the user X includes, for example, a product ID for identifying the product P.

[0068] Step S503: In response to receiving the input of the user X in step S502, a process for purchasing or repairing the product P is executed. The process for purchasing or repairing the product P includes, but is not limited to, for example, a process for shipping the purchased or repaired product P to the user X, a payment process for the purchase or repair of the product P, etc.

[0069] Step S504: In response to receiving the input of the user X in step S502, the product P is put up for sale on the platform α. The process of putting up the product P on the platform α is executed based on the product ID for identifying the product P with reference to the product database unit 342. The process of putting up the product P on the platform α includes, but is not limited to, a process of creating a listing page for viewing detailed information of the product P on the platform α based on the product ID for identifying the product P. Therefore, no input is required from the user X who purchased or repaired the product P. When putting up the product P, the selling price of the product P may not be set. In addition, when putting up the product P, the computer system 310 can issue an NFT of the product P. Putting up the product P may be executed automatically by the computer system 310 in response to receiving the input of the user X in step S502, for example. Alternatively, putting up for sale the product P may be executed by the computer system 310 in response to, for example, receiving an input from the user X in step S502, requesting permission to put up for sale the product P from the user X, and in response to receiving an input from the user X indicating permission to put up for sale the product P. Requesting permission to put up for sale the product P from the user X may be achieved, for example, by transmitting a permission request to put up for sale the product P to a user device operated by the user X.

[0070] In this way, in response to receiving the input from user X in step S502, the computer system 310 executes a process for purchasing or repairing product P and a process for listing product P on platform α for sale, without requiring any input from user X who purchased or repaired product P, thereby making it possible to provide user X with the unique experience of "using a product while waiting for an opportunity to sell it."

[0071] 5, an example in which step S504 is executed after step S503 has been described, but the present invention is not limited to this. Step S504 may be executed at any timing after step S502. Therefore, step S504 may be executed before step S503, or may be executed in parallel with step S503.

[0072] Fig. 6 shows another example of processing executed in the computer system 310. Each step shown in Fig. 6 is executed, for example, by the processor unit 311 of the computer system 310. Fig. 6 shows an example of processing from a purchase offer for a product P on the platform α to relisting the product P. Note that in the embodiment shown in Fig. 6, the seller is "user X" described with reference to Figs. 1 and 5, and the buyer is "user Y" described with reference to Fig. 1. Each step shown in Fig. 6 will be described below.

[0073] Step S601: A first input from a buyer indicating a desire to purchase a put up product P is received. The first input from the buyer is received, for example, from a user device 3202 operated by the buyer. The first input from the buyer includes, for example, a product ID for identifying the product P and information indicating a desired purchase price for the product P. This process may correspond to the buyer selecting the purchase offer area 218 shown in FIG. 2A.

[0074] Step S602: A notification indicating a desire to purchase the put-upon product P is sent to the seller. This notification includes, for example, information indicating the name of the product P, image data of the product P, information indicating the rank of the product P, information indicating the recommended purchase price of the product P, information indicating the buyer's desired purchase price of the product P, price reference information of the product P, and the like. This process may correspond to the screen 220 shown in FIG. 2B being displayed on the user device 3201 operated by the seller. This process may be achieved, for example, by identifying the current owner (i.e., the seller) corresponding to the product ID based on the product ID for identifying the product P, and sending a notification indicating a desire to purchase the put-upon product P to the user device 3201 operated by the seller.

[0075] Step S603: It is determined whether a first input from the seller indicating that the seller agrees to purchase the listed product P has been received, a second input from the seller indicating that the seller wishes to negotiate the selling price of the listed product P has been received, or a third input from the seller indicating that the seller wishes to cancel the purchase of the listed product P has been received. These inputs are received, for example, from a user device 3201 operated by the seller. This process may correspond to the seller selecting any of the selling area 227, the price negotiation area 228, and the cancel area 229 shown in FIG. 2B. This process may be executed, for example, for a predetermined period of time. The predetermined period of time may be, for example, but is not limited to, 1 hour, 3 hours, 6 hours, 12 hours, 24 hours, 2 days, 3 days, etc. If the computer system 310 does not receive any input within a predetermined period, the computer system 310 transmits a notification to the user device 3202 operated by the buyer indicating that the purchase of the product P has been canceled, and transmits a notification to the user device 3201 operated by the seller indicating that the deadline for replying to the purchase offer of the product P from the buyer has passed, and the process ends (normal end). If a first input from the seller indicating that the purchase of the put up product P is accepted is received, the process proceeds to step S607, if a second input from the seller indicating that the seller wishes to negotiate the price of the put up product P is received, the process proceeds to step S604, and if a third input from the seller indicating that the seller wishes to cancel the purchase of the put up product P is received, the computer system 310 transmits a notification to the user device 3202 operated by the buyer indicating that the purchase of the product P has been canceled, and the process ends (normal end).

[0076] Step S604: A second input from the seller is received indicating the desired selling price of the put up product P. That is, the second input from the seller received in step S603 includes information indicating the desired selling price of the put up product P. The second input from the seller may further include information for identifying the product P (product ID).

[0077] Step S605: The desired selling price of the put up product P is presented to the buyer. This process can be achieved, for example, by referring to the product database unit 342, identifying the user ID of the buyer with whom the product P is to be negotiated based on information for identifying the product P (product ID), and transmitting the desired selling price of the put up product P to the user device 3202 operated by the buyer.

[0078] Step S606: It is determined whether a second input from the buyer indicating a desire to purchase the put up product P at the seller's desired selling price has been received. This process may be executed for a predetermined period of time, for example. The predetermined period of time may be, but is not limited to, one hour, three hours, six hours, twelve hours, twenty-four hours, two days, three days, etc. If the result of the determination is "Yes", the process proceeds to step S607, and if the result of the determination is "No", the computer system 310 transmits a notice indicating that the purchase of the product P has been canceled to the user device 3201 operated by the seller, and the process ends (normal end). If a second input from the buyer indicating a desire to purchase the put up product P at the seller's desired selling price has been received, the computer system 310 considers that a first input from the seller indicating an agreement to purchase the put up product P has been received (i.e., the transaction of the product P between the seller and the buyer is considered to have been concluded).

[0079] Step S607: A process is executed to change the owner of the product P purchased by the buyer from the seller (user X) to the buyer (user Y). This process can be achieved, for example, by referring to the product database unit 342 and updating the user ID of the seller of the product P to the user ID of the buyer based on the information for identifying the product P (product ID).

[0080] In steps S607 to S608, the management company of computer system 310 receives product P delivered from the seller. When the management company receives product P from the seller, it may inspect product P (i.e., check the rank of product P). If the rank of product P at the time of sale is higher than the rank of product P at the time of listing or is about the same as the rank of product P at the time of listing, computer system 310 executes the processing from step S608 onwards, which will be described later.

[0081] If the rank of product P at the time of the sale is lower than the rank of product P at the time of listing, computer system 310 identifies the fair price of product P corresponding to the rank of product P at the time of the sale, and if the fair price of product P is lower than the purchase price of product P, notifies both the seller (user X) and the buyer (user Y) of information indicating the fair price of product P and the rank of product P at the time of the sale, in order to sell product P at the fair price. When computer system 310 receives input from both the seller (user X) and the buyer (user Y) indicating that they agree to the sale and purchase of product P at the fair price and rank of product P at the time the sale and purchase is completed, it executes processing from step S608 onwards, which will be described below, and when computer system 310 receives input from at least one of the seller (user X) and the buyer (user Y) indicating that they do not agree to the sale and purchase of product P at the fair price and rank of product P at the time the sale and purchase is completed, it sends a notification indicating that the purchase of product P has been canceled to user device 3201 operated by the seller (user X) and user device 3202 operated by the buyer (user Y), and the processing ends (normal end).

[0082] Step S608: It is determined whether a change in the rank of the product P purchased by the buyer has been received. This process can be achieved, for example, by referring to the product database unit 342 and determining whether a rank change flag for the product ID for identifying the product P is set based on the information for identifying the product P (product ID). If the rank change flag for the product ID for identifying the product P is set, it is determined that a change in the rank of the product P purchased by the buyer has been received. If the determination result is "Yes", the changed rank for the product ID for identifying the product P is identified and the process proceeds to step S609, and if the determination result is "No", the process proceeds to step S610.

[0083] Step S609: The rank of the product P purchased by the buyer is updated to the changed rank. This process may be executed, for example, by referring to the product database unit 342 and based on information for identifying the product P (product ID).

[0084] Step S610: In response to changing the owner of the product P from the seller (user X) to the buyer (user Y) in step S607, the product P purchased by the buyer (user Y) is further put up for sale on the platform α. The process of further putting up the product P on the platform α is executed based on the product ID for identifying the product P with reference to the product database unit 342. The process of further putting up the product P on the platform α includes, but is not limited to, a process of creating a listing page for viewing detailed information of the product P on the platform α based on the product ID for identifying the product P. Therefore, no input is required from the user Y who purchased the product P. When the product P is relisted, the selling price of the product P does not need to be set. In addition, when the product P is relisted, the computer system 310 can issue an NFT of the product P.

[0085] In this way, the computer system 310, in response to changing the ownership of the product P from the seller (user X) to the buyer (user Y) in step S607 without requiring any input from the user Y who purchased the product P, executes a process to further list the product P for sale on the platform α, thereby making it possible to provide the user Y with the unique experience of "using the product while waiting for an opportunity to sell it."

[0086] Although an example has been described in which the computer system 310 automatically executes step S610 in response to step S607, the present invention is not limited to this. For example, before executing step S610, the computer system 310 may transmit a consent request for further listing the product P on the platform α to the user device 3202 operated by the user Y, and execute step S610 only when an input indicating consent for further listing the product P on the platform α is received from the user Y (specifically, the user device 3202 operated by the user Y).

[0087] In the embodiment shown in Figures 5 to 6, an example has been described in which the processor executes a program stored in the memory to realize the processing of each step shown in Figures 5 to 6, but the present invention is not limited to this. At least a part of the processing of each step shown in Figures 5 to 6 may be realized by a hardware configuration such as a control circuit.

[0088] As described above, the present invention has been illustrated using the preferred embodiment of the present invention, but the present invention should not be interpreted as being limited to this embodiment. It is understood that the scope of the present invention should be interpreted only by the claims. It is understood that a person skilled in the art can implement an equivalent scope based on the description of the present invention and technical common sense from the description of the specific preferred embodiment of the present invention.
