And what if I told you that a second team spent the same 20 years, and about 10 million, but they ended up being just a couple of months behind the first team? Why is it okay to say "screw you, someone else came first" in that instance, but not with the first team?
If they come up with essentially the same thing, well, that sucks, but they knew the risk when they decided to invest.
And why do you imagine that this only happens with improvements to technology? Look into the history of the telephone - there were several people working on similar ideas all at essentially the same time.
The race to the patent office can be brutal, but it was implemented so as to encourage timely disclosure of inventions. There is much less benefit from someone who spends 30 years tinkering in his basement before finally revealing his work.
Once a product like the tv is invented, it's much easier for engineers to imagine improvements for it. Coming up with the initial product is much trickier, because you are doing something that hasn't been done before. Sure, another guy may be working on a tv, but the chances are it will be different than yours. The guys working on color? They are still working on the same project, no matter which method they use to get there. They have a template (the tv) with which to formulate their ideas off of.
And that's why "improvement" patents have much narrower claims than patents on brand new ideas. The first inventor gets a broad patent, and can profit by licensing that broad patent to those who develop the improvements. But the improvements also get patents - just of a much narrower scope. That why people who "are still working on the same project, no matter which method they use to get there" can still get their own patent - different ways of arriving at the same effect are still patentable.
That's part of what AvalonXQ and I have been trying to get across. The patent claims you see here are of
extremely narrow scope. They're not just for "using a touch to control a touch screen", they are for a very particular type of touch, that manipulates a very particular type of displayed information, to manipulate it in a very specific way, and they cover
nothing else outside the bounds of those very specific limitations. Can you really claim that the whole entire remainder of the smart phone industry is doomed because they might have to pay a licensing fee to use this one, very specific method?
