What it had to solve
In 1997 every online purchase meant re-entering billing and shipping forms, and shoppers abandoned carts. Amazon wanted buying to be as close to a reflex as possible.
The idea
Store the customer's payment and shipping details once, then let a single on-page order button place the entire purchase — no cart, no forms.
How it works
The server assigns the browser a client identifier tied to stored payment and shipment information; product pages render an order button, and clicking it combines the stored data into a completed order. Amazon filed US patent 5,960,411 in September 1997; it issued September 28, 1999.
What it did
Weeks after the patent issued, Amazon sued Barnes & Noble over its Express Lane and won an injunction. Apple licensed 1-Click in 2000 for a reported $1 million. The patent expired in September 2017, and one-click checkout became an industry standard.
Background
In the late 1990s, buying anything online meant typing an address and card number into forms for every single order. Amazon's team — Jeff Bezos, Peri Hartman, Shel Kaphan and others — realized that once a customer had bought once, the store already knew everything needed to complete the next purchase.
Their answer, filed as US patent 5,960,411 in September 1997 and granted on September 28, 1999: the server keeps the shopper's payment and shipping data behind a client identifier, so a single click on an order button assembles and places the whole order. No shopping cart, no forms.
Amazon enforced the patent immediately: it sued Barnes & Noble in October 1999 over the similar Express Lane feature and obtained a preliminary injunction, forcing Barnes & Noble to add a confirmation click. In 2000 Apple took a license for a reported $1 million and used one-click ordering in its online store and later the iTunes Store.
The patent survived reexamination and expired in September 2017. One-click ordering then spread across e-commerce, with Shopify, Bolt and others building entire products around it.
Why it lands
Each removed form field measurably lifts conversion, so removing the whole form was worth a patent fight.
Owning the patent turned a UI detail into two decades of licensing leverage and a legal moat.
Apple's $1 million license in 2000 proved the idea had standalone value beyond Amazon's own store.
What you can take
The most valuable checkout feature is the one that removes steps; if you invent a friction-removing flow, protect it and rent it out.
Since then
The USPTO confirmed the patent after reexamination in 2010 with narrowed claims; Europe rejected it. After expiry on September 12, 2017, one-click checkout became standard practice, and checkout startups like Bolt, Fast and Shopify's Shop Pay rebuilt their products on the same principle.
