The "monopoly" aspect isn't really relevant here. It's not like you accidentally stumble onto a MIPS patent. If you're infringing it's because you're copying the design.
Well that audacious. I'm will be less daring and say that with 500 patents, you are most certainly wrong about some of them.
Last time I said this, you brought up a 60 year old RF parent, but I'll give you another shot and say that I hav never seen a software patent worth protecting.
My example for a software patent would be the h.264 patent. That's not something a practitioner of ordinary skill would find obvious.
Patents and copyright have grown to become much more defense structures and "keep out" signs, which I think unfortunate, but the basic premise is sound.
The point is that if there really are so many entities just trying to abuse the system, they don't need patents to do it.
