You're right but how the hell is this patentable!? The patent system is patently nonsense if "make there be as few clicks as possible" is worthy of a couple of decades of protection. Probably more context in the patent doc which I'm not going to read because any energy expended on the whole stupid system (other than ranting) is wasted.
I think the reason a lot of people have heard about the one-click-patent is that it has served as the poster child for frivolous patents for the last 25 years.
So yes, your outrage is shared by most people. I stopped holding my breath for reforms though.
They applied for the patent in 1997, which means it expired in 2017.
