First of all, its all about the implementation. People like you think a patent is just about an idea, which is incredibly frustrating how much people misunderstand the difference between generic ideas and implementation. Ideas are meaningless without execution. Thats what the patent claims are for. You don't get a patent for just an idea. You have to figure out HOW. You have to make explicit claims for your method, what is needed to accomplish the idea. THOSE ideas, the ideas that are necessary to achieve the larger vision, are what gets patented.
As Edison said, "1% inspiration, 99% perspiration"
You are quoting the wrong man here, or the right one. It depends on your opinion who should patent office serve, actual inventor or big business.
In theory Edison invented lot's of things in practice he didn't invent jack sh.. He was an opportunists, very wealthy one to begin with much like Gates, Jobs, Zuckerberg, etc. who recognized and bought out others good ideas, shoved them into consumer's throats and made a positive business case. So he was a genuine ultra successful manager or businessman, however you like it. Their business had to be protected so that's where patent office comes into hand and their relationship with big businesses.
In theory patent requires implementation breakdown, in practice implementation could be described very vaguely and still go through and get approved. Not all patent implementations are like that but implementations we are discussing here including one mentioned in this article are as vague as they can be.
Because they are vague as
" The apparatus of claim 25, further comprising a display to show the representation of the 3D object, and wherein the sensor module comprises a proximity sensor to detect movements in proximity to the surface of the display.".
That's your implementation of claimed patented technology right there (and btw this patent is about gestures cause it claims such things as touching the screen surface and lifting your hand in air).
Due to lack of description of implementation we have a long lasting court battles because each side can be proven wrong so the side who wins is the side that has most grease. Your single inventor doesn't stand a chance here.
So in theory yes patent office asks you for implementation description but in practice what they approve is actual purpose and end use of the patent.
If that was not the case Apple could not win on "bounce back" case against Samsung. Why? Because "bounce back" is nothing more than a software behavior that's implemented strictly by code on a very high level. Because its a high level coding it can be coded (read: implemented) in hundreds of different ways and it would still do the same thing.
And somebody asked someone "if you thought about it why didn't you patent it?" short answer being "It would run you at least 10,000 to patent something properly" so that's another proof why patent office is not about inventor but about protecting the industry.
