According to Jeff Bezos, the 1-click purchase wasn't obvious at all, especially when you have a large supply chain system at Amazon. This is mostly due to edge cases like, what if the user cancels the order and the book is already making its way through the warehouse being packaged? What if the number of orders change while the book is being selected from the warehouse?
From what I remember, when a user clicks on the 1-click purchase to buy an item, it actually queues the purchase for a certain amount of time before being acted on by the warehouse, and there are things in place to back it out if the user decides to change the purchase.
That argument would be plausible if Amazon was patenting a particular logistical implementation of 1-click purchase. ("This is a specific device which allows canceled orders to be tracked and routed back to inventory...") But they patented the entire concept, which would prevent even companies with trivial logistics from allowing 1-click purchasing without paying Amazon royalties.
And indeed, according to Tim O'Reilly, Bezos defended the broad patenting of all types of 1-click purchasing. Here is an excerpt of O'Reilly's description of their conversation:
> First off, Jeff wanted to explain why he thought 1-click was original enough to patent. It has nothing to do with the implementation, which he admits is fairly trivial to duplicate, but with the reframing of the problem. At the time he came up with 1-click shopping, everyone was locked in to the shopping cart metaphor, because that's what you do in the real world. You pick up an item and take it to the counter to buy it. On the Web, he realized, something very different was possible: all you had to do was point to an article, and it was yours...
>What's more, Jeff went on, small inventions can often seem extremely obvious in retrospect. The patent literature is full of this kind of thing. The significance of an invention isn't how hard it is to copy, but how it reframes the problem in a new way.
> This may be true, I replied. But it is hard to believe that if Amazon hadn't introduced 1-click ordering (if they were indeed first to do it), that someone else wouldn't have done this. It beggars the imagination that this is so significant and unexpected an innovation that others should be prevented from using it. Patents are meant to promote the common welfare, the idea being that certain ideas won't be developed without government providing a degree of protection. Is this an idea that required that kind of protection to be developed?
I read the article you linked. It gave a different flavor than I thought. It seems there are a couple issues mixed together here.
The obviousness of a solution is hard to judge, especially since the answer is obvious once you see the answer. So it's hard to say whether anyone else would have done it.
My OP was more to point out the lack of obviousness for something like that than one might think on first blush. The wireless music box is obvious to us in hindsight. But in context of wireless radio at the time, most people used it to send messages. As a potential investor in the wireless music box retorted at the time, "Why would you send messages to nobody in particular?" Contextually, multicasting just wasn't in people's minds.
That said, patent system is broken in the way that Amazon and others use it. I can see why Bezos did it, but that can be a slippery slope to stifling innovation, as much as you try to protect against it.
And the lack of a good metric to tell how obvious something is, especially when seeing the answer makes it seem obvious might point to the idea of patents as being hard to enforce well, however good the merits having a patent system might be.
Then why did anyone that wanted to allow their customers to purchase items with a single click have to license from Amazon? If the real innovation that they were protecting was the way that the back-end system was implemented, then why is the front-end piece being (aggressively) licensed out? Something smells fishy about that explanation. It reeks of the MS justification for their patent portfolio (it's defensive only! really!), only to contradict their statements later on (suing TomTom over FAT32 patents; making (empty) public threats against infringements by Linux; etc).
From what I remember, when a user clicks on the 1-click purchase to buy an item, it actually queues the purchase for a certain amount of time before being acted on by the warehouse, and there are things in place to back it out if the user decides to change the purchase.
