1-Click

1-Click, also called one-click or one-click buying, is the technique of allowing customers to make online purchases with a single click, with the payment information needed to complete the purchase having been entered by the user previously. More particularly, it allows an online shopper using an internet marketplace to purchase an item without having to use shopping cart software. Instead of manually inputting billing and shipping information for a purchase, a user can use one-click buying to use a predefined address and credit card number to purchase one or more items.

The United States Patent and Trademark Office (USPTO) issued US 5960411  for this technique to Amazon.com in September 1999. Amazon.com also owns the "1-Click" trademark.

On May 12, 2006, the USPTO ordered a reexamination of the "One-Click" patent, based on a request filed by Peter Calveley. Calveley cited as prior art an earlier e-commerce patent and the Digicash electronic cash system.

On October 9, 2007, the USPTO issued an office action in the reexamination which confirmed the patentability of claims 6 to 10 of the patent. The patent examiner, however, rejected claims 1 to 5 and 11 to 26. In November 2007, Amazon responded by amending the broadest claims (1 and 11) to restrict them to a shopping cart model of commerce. They have also submitted several hundred references for the examiner to consider. In March 2010, the reexamined and amended patent was allowed.

Amazon's U.S. patent expires in 2017.

In Europe, EP application 1134680  on 1-Click ordering was filed with the European Patent Office but refused. A related gift-ordering patent was granted in 2003, but revoked in 2007 following an opposition.
