Abstract

In client-server systems interconnected through a network, a server computer accepts bids from respective client computers while reducing the price of an article stepwise. If a plurality of bids have been made at a certain price, one of the bidders is determined as a winner at the price. The server computer sends information on the confirmation of a knock-down to the winner. The auction is closed upon completion of the knock-down process. The auction is easily and reliably held by using the network.

Claims

1. A method for holding an auction of an article using a client-server system connected through a communication network, comprising the steps of:

causing at least one client computer to display a price of the article;

reducing stepwise the price of the article displayed by the client computer if no bid has been received from the client computer, with the displayed price of the article defined as a first bidding price; and

causing a server computer to determine a winner at a second bidding price if any bid has been received from the client computer, when the price of the article that has been reduced and displayed by the client computer is defined as the second bidding price.

2. The method according to

claim 1

, wherein:

the price of the article decreases stepwise between a predetermined initial price and a predetermined lowest price.

3. The method according to

claim 1

, wherein:

the price of the article decreases stepwise at intervals of a predetermined period.

4. The method according to

claim 1

, wherein:

the price of the article decreases stepwise by a predetermined markdown.

5. The method according to

claim 1

, wherein:

a first bidder is determined as the winner if a plurality of bids have been made.

6. The method according to

claim 1

, wherein:

the winner is determined by lottery if a plurality of bids have been made.

7. The method according to

claim 1

, wherein:

the client computer of the winner displays information on the confirmation of a knock-down.

8. The method according to

claim 1

, wherein:

the client computer displays information on the interruption of bidding if the winner has been determined.

9. The method according to

claim 1

, wherein:

the server computer cancels the determination of the winner unless a response to information on the confirmation of a knock-down has been sent from the client computer of the winner within a predetermined period.

10. The method according to

claim 9

, wherein:

another winner is determined from bidders other than the first-determined winner after cancellation of the determination of the first-determined winner by the server computer if a plurality of bids have been made.

11. The method according to

claim 9

, wherein:

after cancellation of the determination of the first-determined winner by the server computer, the price of the article, which again decreases stepwise from the price at the time of the bid, is displayed by the client computer so as to accept bids.

12. The method according to

claim 1

, wherein:

the auction of the article is interrupted if a response to information on the confirmation of a knock-down has been sent from the client computer of the winner within a predetermined period.

13. The method according to

claim 1

, wherein:

the bid includes a preset desired bidding price.

14. A system for holding an auction of an article using a client-server system connected through a communication network, comprising:

at least one client computer that displays a price of the article and sends a bid; and

a server computer that reduces stepwise the price of the article displayed by the client computer if no bid has been received from the client computer, accepting a bid from the client computer with the reduced price of the article defined as a bidding price, and determining a winner at the bidding price.

15. An apparatus for holding an auction of an article through a communication network, comprising:

a memory that stores an initial price and a lowest price of the article; and

a controller that;

sends auction information, including a price of the article, to the communication network; and

receives bids through the communication network, with the price of the article that has been sent defined as a bidding price,

wherein the controller;

sends the price of the article that is reduced from the initial price to the lowest price every time it is reduced stepwise, as long as the controller has not received the bids; and

determines a winner with the price of the article that has been reduced defined as the bidding price.

16. The apparatus according to

claim 15

, wherein:

the controller reduces stepwise the price of the article from the initial price to the lowest price by a predetermined markdown and at a predetermined markdown timing.
