[10] According to an aspect of the present invention, there is provided an online buyback system including: a database storing product sale information including product identification information, product specification, product sale price, and product sale date; a buyback request information receiving unit receiving buyback request information including product identification information from a computer of a buyback requester accessing a network; a sale checking unit referring to the product sale information stored in the database to check whether or not a product corresponding to the product identification information contained in the buyback request information has been sold; and a buyback processing unit processing such that the product corresponding to the product identification information is collected from the buyback requester when the product is determined to have been sold, and a buyback price of the product is paid to the buyback requester based on a time interval from the product sale date to buyback request date. Mode for the Invention

[11] Exemplary embodiments in accordance with the present invention will now be described in detail with reference to the accompanying drawings.

[12] Fig. 1 is a block diagram of an online buyback system according to an embodiment of the present invention.

[13] An online buyback system 100 includes a database 110, a buyback request information receiving unit 120, a sale checking unit 130, and a buyback processing unit 140.

[14] The database 110 stores product sale information including product identification information, product specification, sale price, and sale date.

[15] The online buyback system 100 collects product sale information concerning precious metals, antiques, and other products sold online or offline and stores it in the database 110. The product sale information includes product identification information, product specification, sale price, sale date, and the like.

[16] The buyback request information receiving unit 120 receives buyback request information including product identification information from a computer 200 of a buyback requester accessing a network. The computer 200 may be a personal computer or a computer of a shop (franchise shop) that allows users to input the product identification information.

[17] For instance, when a customer purchases a precious metal or antique and then changes it to a newer model or buy it back, the customer or buyback requester accesses the online buyback system 100 through his or her own computer 200 and makes a buyback request. The online buyback system 100 provides a user interface to the computer 200 so that the buyback requester can input buyback request information containing product identification information, and receives the buyback request in- formation through the user interface. The buyback request information may be received by the buyback request information receiving unit 120 of the online buyback system 100 through and stored in the database 110.

[18] The sale checking unit 130 refers to product sale information stored in the database

110 to retrieve whether or not a product corresponding to product identification information contained in the buyback request information received by the buyback request information receiving unit 120 has been sold.

[19] That is, when the buyback request information is received by the buyback request information receiving unit 120, the online buyback system 100 refers to product sale information stored in the database 110 by means of the buyback request information receiving unit 120 to retrieve whether or not a product corresponding to product identification information contained in the buyback request information has been sold.

[20] When the product corresponding to the product identification information has been sold, the buyback processing unit 140 processes such that the product is collected from the buyback requester and a buyback price is paid to the buyback requester based on a time interval from product sale date to buyback request date.

[21] That is, when the product is determined by the sale checking unit 130 to have been sold, the buyback processing unit 140 of the online buyback system 100 processes such that the product is collected from the buyback requester and a buyback price is paid to the buyback requester based on a time interval from product sale date to buyback request date, thereby performing an online buyback process between sellers and purchasers of products, such as precious metals or antiques, with no limitations in terms of time and space.

[22] The buyback processing unit 140 may pay a buyback price to the buyback requester based on comparison between a time interval from product sale date to buyback request date and a predetermined expiry date.

[23] The buyback price is divided into a refund before expiry date, a refund on expiry date, and a refund after expiry date. The buyback price may be determined by a buyback rate or 'main/sub raw material price of product'.

[24] The buyback rate may vary according to a time interval from product sale date to buyback request date. For instance, the buyback rate is set to be lower if the time interval is short, and it is set to be higher if the time interval is long.

[25] If the time interval is shorter than a predetermined expiry date, the buyback processing unit 140 may be configured such that 'product sale price x buyback rate less than 100%', i.e., a smaller amount of money than the product sale price, is paid as the buyback price.

[26] If the time interval is equal to the predetermined expiry date, the buyback processing unit 140 may be configured such that 'product sale price x buyback rate of 100%', i.e., the same amount of money as the product sale price, is paid as the buyback price.

[27] If the time interval is longer than the predetermined expiry date, the buyback processing unit 140 may be configured such that 'product sale price x buyback rate more than 100%', i.e., a larger amount of money than the product sale price, is paid as the buyback price.

[28] Meanwhile, if the time interval from the product sale date to the buyback request date is shorter than a predetermined expiry date, the buyback processing unit 140 may be configured such that the buyback price amounts to '((product sale price - main/sub raw material price of product) x time interval from product sale date to buyback request date ÷ time interval from product sale date to expiry date) + main/sub raw material price of product'.

[29] If the time interval is equal to a predetermined expiry date, the buyback processing unit 140 may be configured such that the buyback price amounts to '((product sale price - main/sub raw material price of product) + main/sub raw material price of product x time interval from product sale date to buyback request date ÷ time interval from product sale date to expiry date)'.

[30] If the time interval is larger than a predetermined expiry date, the buyback processing unit 140 may be configured such that the buyback price amounts to 'product sale price + ((product sale price - main/sub raw material price of product) x value increase rate (%) of product ÷ 365 x time interval from expiry date to buyback request date)'.

[31] Fig. 2 is a table for showing of a method of calculating product buyback price in an online buyback system according to an embodiment of the present invention. It is assumed that a product has a product identification number Cl of 'AOOOl' product sale date C2 is January 1, 2005, buyback expiry date C3 is January 1, 2007, product sale price C4 amounts to W

1,000,000, main/sub raw material price C5 of the product amounts to W

500,000, and value increase rate C6 is 4%.

[32] If the time interval from the product sale date to the buyback request date is shorter than a predetermined expiry date (for example, when the buyback request date falls on January 1, 2006), the buyback price amounts to '((product sale price - main/sub raw material price of product) x time interval from product sale date to buyback request date ÷ time interval from product sale date to expiry date) + main/sub raw material price of product' = ((C4 - C5) x (buyback request date - C2) ÷ (C3 - C2)) + C5 = (( W 1,000,000 - W

500,000) x 365 ÷ 730) + W

500,000 = W

750,000.

[33] If the time interval from product sale date to buyback request date is equal to the predetermined expiry date (for example, when the buyback request date falls on January 1, 2007), the buyback price amounts to '((product sale price - main/sub raw material price of product) + main/sub raw material price of product x time interval from product sale date to buyback request date ÷ time interval from product sale date to expiry date)' = ((C4 - C5) + C5 x (buyback request date - C2) ÷ (C3 - C2)) = (( w 1,000,000 -

W

500,000) + w

500,000 x 730 ÷ 730) = W

1,000,000.

[34] If the time interval from product sale date to buyback request date is longer than a predetermined expiry date (for example, when the buyback request date falls on January 1, 2008), the buyback price amounts to 'product sale price + ((product sale price - main/sub raw material price of product) x value increase rate (%) ÷ 365 x time interval from expiry date to buyback request date)' = C4 + ((C4 - C5) x C6 ÷ 365 x (buyback request date - C3)) = w 1,000,000 + ((

W

1,000,000 -

W

500,000) x 4% ÷ 365 x 365) = w

1,020,000.

[35] Accordingly, the online buyback system allows an online buyback process to be performed between sellers and purchasers of products, such as precious metals or antiques, with no limitations in terms of time and space. In addition, after purchasing rare products such as precious metals or antiques, customers can be rewarded at a reasonable buyback price. Further, straight transactions of rare products such as precious metals or antiques can be conducted.

[36] The online buyback system 100 may further include a member management unit

150.

[37] The member management unit 150 receives member information including personal information and bank account of a buyback requester from a computer 200 of the buyback requester, conducts a member registration or modification process, and refers to the member information to conduct a member authentication process when the buyback requester accesses a network.

[38] That is, the present embodiment provides a membership-based online buyback service. The above-mentioned member registration or modification and authentication processes are well-known in the art before application of the present invention and a detailed description thereof will thus be omitted herein.

[39] In this case, the buyback processing unit 140 of the online buyback system 100 may pay the buyback price by making an online transfer of the buyback price from a bank account of the online buyback system 100 to a bank account of a buyback requester.

[40] The online buyback system 100 may further include a purchase request information receiving unit 160 and a sale processing unit 170.

[41] The purchase request information receiving unit 160 receives purchase request information including product identification information from a computer of a purchase requester accessing the network.

[42] The sale processing unit 170 requests payment of a product price from the computer of purchase requester according to the purchase request information received by the purchase request information receiving unit 160, processes such that the product is sent to the purchase requester after the purchase requester pays for the product, and processes such that product sale information including product identification information, product specification, product sale price, and product sale date is stored in the database.

[43] That is, according to the present embodiment, the online buyback system 100 is op- eratively associated with a product sale module of precious metals, antiques, and other products. The online buyback system 100 sells products through the sale processing unit 170 according to product purchase requests from users, and provides buyback services with respect to the sold products through the buyback processing unit 140.

[44] In this case, the online buyback system 100 may provide membership-based services for product purchase and buyback through the member management unit 150. In addition, the online buyback system 100 may be configured such that the buyback processing unit 140 pays a buyback price by making an online transfer of the buyback price from a bank account of the online buyback system 100 to a bank account of a buyback requester, and such that the sale processing unit 170 receives a product price by making an online transfer of the product price from a bank account of a purchase requester to a bank account of the online buyback system 100. Accordingly, the online buyback system 100 may be configured to make online payment on product purchase and buyback processes.

[45] Fig. 3 is a flow chart of product buyback operation in an online buyback system according to an embodiment of the present invention.

[46] In operation Sl 10, the online buyback system 100 collects product sale information including product identification information, product specification, product sale price, and product sale date of products sold online or offline and stores the product sale information in a database.

[47] In operation S 120, buyback request information including the product identification information is received from the computer 200 of a buyback requester accessing a network. In operation S 130, the online buyback system 100 refers to the product sale information stored in the database to retrieve whether or not a product corresponding to the product identification information included in the buyback request information has been sold.
