“Then they [Amazon]pioneered 1-Click payment”
Actually they didn’t, they popularized a prior method, which after re-examination by the patent office was restricted to the use online, only in shopping carts.
The idea of a single click payment or financial transaction had been implemented many times before, however, prior to 1982 software patents were extremely hard to get for individual functions of so-called unique concepts, and were reserved for much broader, unique “inventions”.
In 1984, I was one of many working on Chemical Banks Pronto Home Banking System. For transfers between accounts within the bank, we initiated a 1-click on the UI for the PC Junior version of Pronto.
As far as I’m aware, nothing from Pronto was patented due to the high cost at the time. It wasn’t until the late 1980’s software patents started to be filed for individual methods, by the mid-90’s software patents became commonplace, and their use both defensive and offensive, sadly became commonplace too.
