Abstract

A method for distributing a live auction over the Internet to remote bidders. A human proxy attends the live auction in order to monitor the auction and compose status updates that are distributed to remote bidders via the Internet in real time to allow the remote bidders to follow the auction. Remote bidders may place bids for items that are transmitted via the Internet to the human proxy, who may then submit the bids to the auctioneer, components that facilitate distribution of the live auction over the Internet include: an auction console, an auction sever, collector/redistributor nodes, and client programs.

Claims

1. A system for allowing remote bidders to participate by computer in a live auction conducted by a human auctioneer in the presence of on-site bidders, the system comprising:

an auction console program which runs on a computer at a site of the auction, the auction console program providing an interface for a human proxy to communicate with the remote bidders in real time about the live auction, the interface providing functionality for the human proxy to receive bids from the remote bidders for communication to the auctioneer, and further providing functionality for the human proxy to enter information about a current state of the auction, including information about successful bids from on-site bidders;

an auction server which communicates with the console program and with computers of the remote bidders, the auction server programmed to maintain a real time auction state which reflects the information entered by the human proxy and bids submitted by the remote bidders, the auction server further programmed to communicate information about the real time auction state to the remote bidders to allow the remote bidders to monitor the auction in real time; and

a plurality of physical network nodes coupled between the auction server and the computers of the remote bidders, the nodes programmed to pass the real time auction state information from the auction server to the remote bidders, and programmed to pass bid messages from the remote bidders to the auction server for processing;

wherein at least some of the plurality of nodes are further programmed to filter bid messages from the remote bidders based on auction state information received from the auction server, to thereby prevent at least some of the bid messages that represent invalid bids from unnecessarily being passed to the auction server.

2. The system as in claim 1, wherein the plurality of nodes include multiple leaf nodes, each leaf node being programmed to maintain connections with a respective subset of the remote bidders.

3. The system as in claim 2, wherein the plurality of nodes are coupled to the auction server to form a tree structure.

4. The system as in claim 1, wherein at least some of the nodes are programmed to block bid messages based on comparisons of bid amounts of the bid messages to a current high bid.

5. The system as in claim 1, wherein at least some of the nodes are programmed to block bid messages that do not correspond to a currently valid auction.

6. The system as in claim 1, wherein at least some of the nodes are programmed to block bid messages that do not correspond to a currently valid lot.

7. The system as in claim 1, wherein at least some of the nodes are programmed to block a request by a user to connect to a current auction when the user is not authorized to participate in the current auction.

8. The system as in claim 1, wherein the auction console program includes user interface functions for the human proxy to select predetermined auction status messages to broadcast to the remote bidders.

9. The system as in claim 1, wherein the auction console program comprises an applet which runs within a web browser program.

10. The system as in claim 1, further comprising a client program that is adapted to be used by the remote bidders, the client program configured to encapsulate a bid submission from a remote bidder for transmission to the auction server, and to display real time auction status information to the remote bidder.

11. The system as in claim 1, wherein the auction server comprises a database which stores state information for multiple auctions concurrently, including auctions occurring in different locations.
