Now try to understand why innovation existed outside patent motivations. Then look up what big companies do with all those patents. Only then will you see the real effect of the patent system.

Now you might say that a lot of those open source research projects are funded by big companies, so they don't count. But most development on popular open source projects is funded by big or medium-size companies. Research isn't any different in this regard.
I think it's no accident that most of your examples are hardware, not software. The problem there is that open source hardware is difficult to make work, not that open source research is difficult to make work. The other main example you gave is Unix, but FOSS didn't exist in 1973--of course it wasn't open source by the modern definition. Its research successor, Plan 9, was open source.
Disclaimer: I work on one of those open source research projects.
Not sure you can lump 3 very different types of entities into one group.
I agree with your 1st type (startups) but what about #2 (academics) and #3 (FOSS volunteers) - what are some examples that "most innovations" come from them?
