FRAMINGHAM (04/24/2000) - Amazon.com Inc.'s patented one-click system enables repeat online customers to place orders without re-entering credit-card or address information. Part of the patent covers the way Amazon stores billing and shipping data. In December, Amazon obtained a preliminary court injunction against Barnesandnoble.com that prevents the Amazon competitor from using the one-click system.
Priceline.com patented a method by which a customer could propose a price for a product or service, and the order would be filled if a seller was willing to accept that price. Priceline.com sued Microsoft Corp. and its Expedia Inc. travel service for allegedly violating Priceline's method of letting consumers propose their own prices for flights and hotel rooms.
