If you purchased anything from a website using a one-click purchase button, you indirectly paid Amazon for that ability, at least up until September 11, 2017 when Amazon’s patent to this technology expired. As a result, one-click purchasing might become the new norm.
In 1997, Amazon filed for a business method patent to one-click purchasing, which allows return shoppers to purchase items with just a single click of a button instead of having to proceed through a prolonged checkout process. The patent issued in 1999, at which point Amazon sued Barnes & Noble for patent infringement based on a similar technology used during Barnes & Noble’s checkout process. After extended litigation, the two companies settled in 2002. Not wanting to face similar litigation, Apple licensed the patent in 2000 to simplify ordering from the Apple Store.
