Something that's bothered me about user-facing patents:

Let's assume that the idea of using a keyboard key to move between input fields in a software form is not obvious, and in fact is a brilliant stroke of genius the likes of which the world is not likely to see again. If that one guy hadn't been born, we would have gone thousands of years with no method, keyboard-based, mouse-based, or otherwise, of moving from one input field to another input field. Every piece of software would use nonconfigurable timers, and you'd just have to hope you could type fast enough.

I don't see what the hypothetical benefit of extending patent protection to this brilliant idea is supposed to be.

Say you're the company who comes up with the idea. You can benefit by including it in your product, where all your users can see it. In other words, the benefit you get from coming up with this idea is that you can publish it for the world to see, and that's the only way you can benefit from it. A usability feature that your users cannot use or know about doesn't increase usability.

Even though the idea isn't obvious, the implementation is. If you disclose your brilliant idea, everyone will copy it and your advantage in the marketplace will be transitory.

So... what is the purpose of giving you a patent? That cripples the marketplace, but it fails to realize the benefit of patents, publication. Publication necessarily had to happen anyway.

But that’s not the criteria for granting a patent. It doesn’t have to be a stroke of genius. It can be something that many people could invent at the particular moment of the filing (as evidenced by many cases of near-simultaneous patent filings, like Daimler and Benz competing for the ICE in the 1880s). It just needs to be demonstrably novel.

I’m not saying tabbing back and forth through dialog fields qualifies, but then again it’s hard to place oneself in 1980.

Err... wasn't your post a perfect example of why patents exist?

The concept probably has a real name, I call it first mover disadvantage. It is much easier to copy a mechanism than to invent it. So why even try? Every thing you have to spend real effort to invent is trivially copied the instant you try to sell it. And them copying it don't have to bear the nearly the R&D expenses you did. so it is trivial for them to sell this mechanism for less meaning you don't even get a fair slice of the pie.

So to try and limit this imbalance we invent a legal fiction, ownership, not of a physical thing, but the way it works. Not forever, but for 20 years you get ownership over those works.

Patents do have their problems, But I think the core idea is sound, create a registry of mechinisms, use this to provide economic protection to the inventor.

> A usability feature that your users cannot use or know about doesn't increase usability.

Cannot is maybe doing a lot there. There's plenty of usability features that aren't really obvious or apparent unless you look very closely. Ex: pinball machines have timed shots, but there's almost always a grace period so if you contact the ball with your flipper around when the timer hits zero and it makes the shot, chances are you'll get credit for it even though the timer expired. That's a usability feature most users won't ever notice. At WhatsApp, I would never send an S40 user a verification code where the 4th digit was 8, because if you got a text message with 123-890, s40 would turn -8 into an 8th note emoji; until today, probably 3 people knew that ... but it dramatically improved usability.

If I had gotten a patent on the 'avoid -8 in verification codes', then the technique would have been public for everyone to see. So publication for exclusivity / forced licensing is an exchange of value between society and the inventor. Of course, avoid -8 is pretty obvious, when someone testing the s40 client complains about getting an 8th note in their verification code message, you make a quick tweak to code selection to avoid sending those.

For an invention that must be disclosed to be used, society isn't really getting anything in return for exclusivity. Maybe promotion of progress, theoretically, I guess, in that whoever thinks of it first gets paid; leading more people to think about things?

> move between input fields in a software form

IBMs earliest block mode terminals with field entry, including the 3270, predate the microprocessor. They were fully implemented with fixed hardware control.

IBM also infamously patented the XOR cursor.

Presumably it's to give you an advantage for putting in the work to develop it for a period of time.

> the benefit you get from coming up with this idea is that you can publish it for the world to see, and that's the only way you can benefit from it

That’s your opinion, but it’s not the spirit of the law. I’m personally fully against Intellectual Property, including for movies and music, for reasons that are obvious (public money is being spent aimlessly trying to prevent two private individuals from copying things that are copied by their very nature of being published - or trying to prevent people from using ideas that are contagious - what next, put a copyright on political ideas? on dance moves? on beautiful colors?) but that’s not the law.

> we would have gone thousands of years with no method

There are other methods: The 4 arrows. The tab method is much more efficient and easy to implement, but we would have gone with the 4-arrows-to-navigate-fields method.

You can say the same about swipe to unlock and that had been litigated to death.
