Publication number: 20090037314Abstract: An auction method for implementing automatic bid status refresh and item attribute updates in an electronic exchange. The method includes the step of receiving update configuration information from remote bidders via a distributed computer network. The update configuration information includes a time interval for receiving bid status updates. An auction is conducted wherein bid information received from the remote bidders is compared to determine a bid status and wherein the bid status is used to determine the bid status updates for the remote bidders. The bid status includes information regarding the most competitive, or winning, bid and any associated terms. The bid status updates are disseminated to the remote bidders via the distributed computer network in accordance with the update configuration information. At the conclusion of the auction, an auction winner is designated in accordance with the latest most competitive bid of the bid status.Type: ApplicationFiled: July 24, 2001Publication date: February 5, 2009Inventors: Kim Powell, Liza Lyons, Dave Stephens, Kareem Benjamin, Ben Gu, James Wang
