1-Click
online purchasing with only a single mouse click
1-Click, also called one-click or one-click buying, is the technique of allowing customers to make purchases 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. Since the expiration of Amazon's patent, there has been an advent of checkout experience platforms, such as ShopPay, Simpler, PeachPay, Zplit, and Bolt which offer similar one-click checkout flows.
Patent
The United States Patent and Trademark Office (USPTO) issued a patent 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.
This brief starts where responsible research should: with the source description of “1-Click” as online purchasing with only a single mouse click. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as online purchasing with only a single mouse click. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jun 10, 2026. The linked authority identifier is Q4545770. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1999, 2006 and 2007.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
