Patent number: 6189003Abstract: A system and method to provide buyers with information that supports the selection of qualified vendors and service providers at the precise time they are prepared to make a purchase. To accomplish its function, the system includes three core elements: (1) a data retrieval system that makes it easy for ready and willing buyers to find and contact qualified businesses; (2) a proprietary electronic database with enhanced information regarding local businesses; (3) an electronic distribution network that employs live, enhanced directory assistance (EDA) operators via telephone as well as the World Wide Web, and simplifies the connections between motivated buyers and qualified sellers. Buyers are able to search the database of businesses to find the most qualified providers of goods/service that match their unique criteria. Sellers can use the service to better promote their offerings to a market that has moved beyond window shopping and that is ready to buy.Type: GrantFiled: October 23, 1998Date of Patent: February 13, 2001Assignee: WynWyn.com Inc.Inventor: Fernando Leal
