## Abstract

The present invention relates to a method, apparatus and system for providing a random additional post-payment discount for electronic commercial transactions in an open market, and particularly to a method, apparatus and system for providing a random additional post-payment discount of 1% to 100% of the initial payment amount after the purchase price has been paid when you select one or more products for purchase in an online open market where virtual sales space is offered to unspecified number of sellers.

## Claims

### Claim 1

A random additional discount apparatus for receiving at least one random additional discount target product from a seller terminal, receiving a random additional discount request from a buyer terminal upon payment for a purchase of the product and providing a random additional discount price to the buyer terminal in response to the random additional discount request,
wherein the apparatus is configured to:
extract a random additional discount amount in response to the random additional discount request;
determine whether the extracted random additional discount amount satisfies a predetermined condition;
transmit the random additional discount price determined by the random additional discount amount satisfying the predetermined condition to the buyer terminal; and
repeat the process of extracting a new random additional discount amount and determining whether the new random additional discount amount satisfies the predetermined condition, and
wherein the predetermined condition that the determined random additional discount amount Di should satisfy is
ΣCk−ΣDk≥0,
when M sellers sell products on the open market the total result of product sales by the M seller for a predetermined period of time is summarized as follows:
RT=ΣR1+ΣR2+ . . . ΣRk+ . . . +ΣRM
(Here, ΣRk=sales revenue of the seller k, RT=total sales revenue of all the M sellers);
CT=ΣC1+ΣC2+ . . . ΣCk+ . . . +ΣCM
(Here, ΣCk=sales commission received from the seller k, CT=total sales commission received from all the M sellers);
DT=ΣD1+ΣD2+ . . . ΣDk+ . . . +ΣDM
(Here, ΣDk=discount subsidy provided by the open market operator for the sales of the product of the seller k, DT=total discount subsidy provided by the open market operator for the sales of the products of all the M sellers).

### Claim 2

A random additional discount apparatus for receiving at least one random additional discount target product from a seller terminal, receiving a random additional discount request from a buyer terminal upon payment for a purchase of the random additional discount target product and providing a random additional discount price to the buyer terminal in response to the random additional discount request,
wherein the apparatus is configured to:
extract a random additional discount amount in response to the random additional discount request;
determine whether the extracted random additional discount amount satisfies a predetermined condition;
transmit the random additional discount price determined by the random additional discount amount satisfying the predetermined condition to the buyer terminal; and
repeat the process of extracting a new random additional discount amount and determining whether the new random additional discount amount satisfies the predetermined condition, and
wherein the predetermined condition that the determined random additional discount amount Di should satisfy is
CT−DT≥0,
when M sellers sell products on the open market the total result of product sales by the M seller for a predetermined period of time is summarized as follows:
RT=ΣR1+ΣR2+ . . . ΣRk+ . . . +ΣRM
(Here, ΣRk=sales revenue of the seller k, RT=total sales revenue of all the M sellers);
CT=ΣC1+ΣC2+ . . . ΣCk+ . . . +ΣCM
(Here, ΣCk=sales commission received from the seller k, CT=total sales commission received from all the M sellers);
DT=ΣD1+ΣD2+ . . . ΣDk+ . . . +ΣDM
(Here, ΣDk=discount subsidy provided by the open market operator for the sales of the product of the seller k, DT=total discount subsidy provided by the open market operator for the sales of the products of all the M sellers).

### Claim 3 (depends on 2)

The random additional discount apparatus of claim 2,
wherein the predetermined condition that the determined random additional discount amount D, should satisfy is
CT−DT≥0 and ΣCk−ΣDk≥0,
wherein,
if Ck−Dk<0 then it is determined whether the condition CT−DT≥MTH is satisfied;
if the condition CT−DT≥MTH is satisfied then the determined random additional discount price is transmitted to the buyer terminal;
if the condition CT−DT≥MTH is not satisfied then the process of extracting a new random additional discount amount and determining whether the new random additional discount amount satisfies the above conditions is repeated; and
MTH is the threshold margin of the open market operator for the sales of products of all the M sellers for the predetermined period.

### Claim 4 (depends on 3)

The random additional discount apparatus of claim 3,
wherein the total amount of the discount subsidy that will be applied to the random additional discount service is displayed on the buyer terminal.

### Claim 5

A random additional discount method provided by a random additional discount apparatus for receiving at least one random additional discount target product from a seller terminal, receiving a random additional discount request from a buyer terminal upon payment for a purchase of the random additional discount target product and providing a random additional discount price to the buyer terminal in response to the random additional discount request,
wherein the method comprises:
receiving from the seller terminal the seller information and at least one random additional discount target product for registration;
receiving from the buyer terminal the buyer information and payment completion information for a product to purchase;
in response to the payment completion information, transmitting at least one random additional discount price to the buyer terminal; and
