Abstract

Methods, systems and data structures are described for conducting normalized synthetic continuous double auctions. A method includes participating in a normalized auction having contingent bidding on a plurality of heterogeneous item auctions. Contingent bidding includes price normalization as a function of at least one attribute. A composite reverse auction, defined by a bid set including a first contingent bid on a first of the plurality of heterogeneous item auctions and a second contingent bid on a second of the plurality of heterogeneous item auctions, is ended when i) the first contingent bid from the bid set is recognized as a winning bid and substantially simultaneously ii) the second contingent bid from the bid set is withdrawn as a remaining bid.

Claims

1. A method, comprising participating in a normalized auction having contingent bidding on a plurality of heterogeneous item auctions,

wherein contingent bidding includes price normalization as a function of at least one attribute,

wherein a composite reverse auction, defined by a bid set including a first contingent bid on a first of the plurality of heterogeneous item auctions and a second contingent bid on a second of the plurality of heterogeneous item auctions, is ended when i) the first contingent bid from the bid set is recognized as a winning bid and substantially simultaneously ii) the second contingent bid from the bid set is withdrawn as a remaining bid.

2. The method of claim 1, wherein the bid set is visible to at least one member selected from the group consisting of a) at least one first seller associated with the first of the plurality of heterogeneous item auctions, b) at least one second seller associated with the second of the plurality of heterogeneous item auctions, and c) buyers bidding on the first of the plurality of heterogeneous item auctions or the second of the plurality of heterogeneous item auctions.

3. The method of claim 1, wherein the bid set is visible to all three of a) at least one first seller associated with the first of the plurality of heterogeneous item auctions, b) at least one second seller associated with the second of the plurality of heterogeneous item auctions, and c) buyers bidding on the first of the plurality of heterogeneous item auctions or the second of the plurality of heterogeneous item auctions.

4. The method of claim 1, wherein the first contingent bid from the bid set is recognized as the winning bid when a seller accepts a bid defined by the first contingent bid.

5. The method of claim 1, wherein the first contingent bid from the bid set is recognized as the winning bid when a buyer accedes to an ask defined by the first contingent bid.

6. The method of claim 1, wherein contingent bidding includes price normalization as a function of at least two heterogeneous attributes.

7. The method of claim 1, wherein at least one of the plurality of heterogeneous item auctions includes an open continuous double auction.

8. The method of claim 1, wherein participating includes running the synthetic continuous double auction including closing one of the plurality of heterogeneous item auctions.

9. The method of claim 8, further comprising updating at least one other bid set.

10. The method of claim 1, wherein participating includes agreeing to accept an obligation to sell at least one item in the synthetic continuous double auction.

11. The method of claim 10, further comprising updating at least one of the plurality of heterogeneous item auctions.

12. The method of claim 10, further comprising ending one of the plurality of heterogeneous item auctions by accepting a bid.

13. The method of claim 1, wherein participating includes agreeing to accept an obligation to buy at least one item in the synthetic continuous double auction.

14. The method of claim 13, further comprising updating the bid set.

15. An electronic medium, comprising computer or machine readable program elements translatable for implementing a method including:

participating in a normalized auction having contingent bidding on a plurality of heterogeneous item auctions,

wherein contingent bidding includes price normalization as a function of at least one attribute, and

wherein a composite reverse auction, defined by a bid set including a first contingent bid on a first of the plurality of heterogeneous item auctions and a second contingent bid on a second of the plurality of heterogeneous item auctions, is ended when i) the first contingent bid from the bid set is recognized as a winning bid and substantially simultaneously ii) the second contingent bid from the bid set is withdrawn as a remaining bid.

16. An apparatus, comprising a computer network including at least one auction server, at least one seller client and at least one buyer client,

wherein the at least one auction server, the at least one seller client and the at least one buyer client are participating in a normalized auction having contingent bidding on a plurality of heterogeneous item auctions,

wherein contingent bidding includes price normalization as a function of at least one attribute, and

wherein a composite reverse auction, defined by a bid set including a first contingent bid on a first of the plurality of heterogeneous item auctions and a second contingent bid on a second of the plurality of heterogeneous item auctions, is ended when i) the first contingent bid from the bid set is recognized as a winning bid and substantially simultaneously ii) the second contingent bid from the bid set is withdrawn as a remaining bid.

17. A data structure, comprising a bid set that defines at least in-part a normalized auction, the bid set including a first contingent bid on a first of the plurality of heterogeneous item auctions and a second contingent bid on a second of the plurality of heterogeneous item auctions,

wherein the bid set includes price normalization as a function of at least one attribute, and

wherein the normalized auction is ended when i) the first contingent bid from the bid set is recognized as a winning bid and substantially simultaneously ii) the second contingent bid from the bid set is withdrawn as a remaining bid.

18. Signal transmission or receiving apparatus embodying a computer program product comprising computer program means adapted to perform the steps of participating in a normalized auction when the program is run on a computer,

characterized in that participating in a continuous double auction includes participating in a normalized auction having contingent bidding on a plurality of heterogeneous item auctions, wherein contingent bidding includes price normalization as a function of at least one attribute, wherein a composite reverse auction, defined by a bid set including a first contingent bid on a first of the plurality of heterogeneous item auctions and a second contingent bid on a second of the plurality of heterogeneous item auctions, is ended when i) the first contingent bid from the bid set is recognized as a winning bid and substantially simultaneously ii) the second contingent bid from the bid set is withdrawn as a remaining bid.

19. A computer program as claimed in claim 18, embodied on a computer-readable medium.
