The patent system somehow has morphed from shield to sword. Protecting inventors is one path toward innovation, but it should be a byproduct of maximizing innovation and not the end state. If the objective of the patent system is to foster innovation, then it should grant patents only if they are necessary for innovation, i.e., innovation wouldn't reasonably occur otherwise.

I like that idea, and I believe it rings true with most responsible people. However, it's difficult to measure. As an example, in the recent Apple v/s Samsung, if it weren't for Apple, we would still be dealing with shitty Nokia, Samsung and Sony Ericsson phones with crap OSes, no decent applications, and the phones would be anything but smart - because there was no need to improve. Once Apple made everyone lift thei…
There is no magical solution, but the contours of the ideal system will account for the capital requirements of an invention. Areas with low capital requirements, such as "slide to unlock" and "one-click buying," should not warrant patent protection.
Not because they require less ingenuity, but because even absent patent protection, companies would still continue to differentiate through new features and ideas.
It's very similar to music and movies. Artists continue to introduce new sounds and new films even though success spawns a host of copycats.
Would Apple cease innovation on software features -- like "slide to unlock" -- if they weren't granted patent protection? I think it's reasonable to assume not because of the relatively small capital requirements and because of their passion to advance technology.
