Chris,
I am not (I hope) a stupid moron. But I have seen inventions that I should have thought of but did not.
One of these is the passive holographic optical element backlight for PDA screens.
In the pioneering PDA project I was on, we spent months trying to make an electroluminescent backlight work. We could not for many reasons. Finally we went for the usual reflective layer.
Then Polaroid pitched us a reflective layer that was a holographic optical element. It worked amazingly well.
I felt really stupid.
Not only had I just wasted months, but I had worked with holographic optical elements before.
The use of an aspheric surface as a HOE never occurred to me.

I haven't seen anyone arguing that patents should be abolished or that novel applications of technology should not be patentable but rather how what to the non-expert may seem very specific patents in fact have very broad implications. The fear is that this is stifling innovation and deterring development.
The example earlier of Pac-Man is still a good example to use to demonstrate the problem that many people argue is happening today. Despite apparently seeming to be a very specific patent at the time with hindsight we can see that it would have had a very broad impact on the subsequent history of computer games. And the argument that folk could have licensed the patent fails if you look back at the start of the games industry. What today is a multi-billion a year industry truly did start in the bedrooms of teenagers, I know I was one of them!
