In 1997, Jeff Bezos filed a patent application for a button. Not a clever button, not a mechanical one — a virtual button that let an Amazon customer buy something with a single click, using payment details the site had already stored. Two years later the US Patent and Trademark Office granted it, and for eighteen years every American retailer that wanted the same convenience had to license the idea from Amazon or brace for a lawsuit. Apple paid a million dollars for the right to use it in the iTunes Store. Then, in September 2017, the patent finally expired, and the race to clone the button was on. The story of that one click is the story of friction — the invisible tax on every online purchase you have ever made.
🧠 The Patent on a Button
The patent — US 5,960,411, filed September 1997, granted September 1999 — protected the process of buying with one click when your address and card were already on file. It sounds absurdly broad, and it was: critics called it a patent on a business method, and the European Patent Office rejected the European version in 2007 on grounds of obviousness. But in America it held. Barnes & Noble launched its own “Express Lane” one-click option and was hit with a preliminary injunction. Apple, wanting one-click for its online store, simply paid Amazon for the license. The result: a single UX pattern was legally off-limits to the entire US retail industry for nearly two decades. That is how valuable removing one step can be.
🤔 The $12 Million Optional Field
Here is what friction actually costs. Expedia noticed that customers were confused by an optional “Company” field on its booking form — some typed their bank’s name there, then entered the bank’s address instead of their home address, and the bookings failed. They deleted one field, and Expedia gained an estimated $12 million in profit a year. One field. Meanwhile Baymard Institute, averaging 50 studies, puts the average cart abandonment rate at 70.22% — and of the shoppers who leave, 17% say the checkout was too long or complicated, 18% say they were forced to create an account. The counterintuitive truth: in online shopping, the customer is not defeated by price or product. They are defeated by effort.
🔗 Friction Is the Business
Every product that sells an emotional experience runs on this. When someone comes to a fortune reading or a digital companion, they arrive carrying an impulse — and every field, every page jump, every “create an account first” wall is a cooling fan aimed at that impulse. The goal is to let the emotion finish its job while it is still warm: fewer steps, saved payment details, no registration, instant result. The same logic governs advertising. A call-to-action is only as strong as the path behind it — a great “click here” followed by five more pages is a leak, not a funnel. And for anyone writing fiction: a character hesitating at a checkout is friction given a heartbeat.
🎲 The Second Click
Barnes & Noble could not use one-click ordering, so its lawyers built a workaround: make the customer click a second time to confirm the purchase. That patent-avoidance hack is why “confirm your order” pages exist all over the internet today — the second click you barely notice is a ghost of a 1999 courtroom. Same idea, two legal cultures: the US said patentable, Europe said obvious. Next time you check out online, count the clicks between wanting something and owning it. You will feel the tax.
