Man, some patents seem like such a joke. Especially many software patents.
I can also however feel the fear in small companies, it can be a bit confusing. I have been taling to my boss (small 13 person company) to consider allowing some GNU GeneralPublicLicense usage, because we have no problem giving source code to our customers, though the idea of putting code out in the public just feels weird to those from a different background and/or generation. It was something of value that was put into the system, and took money to produce. But the only people who'd care about it would really be our customers if anything ever happened to us and they needed long term code support. Oh, and me, because I'd have to remove all the potentially unprofessional comments.
Anyway, that's a slightly different topic, because it gets more into code "production." Other notions, like how we build machines, my boss can see it in a relatively open mindset. He sees no point in patenting the technology we invent in house because things like industry specific temperature controlled boxes (cough: Stratsys), are absolutely absurd to patent, and we'd get trashed in legal fees if anyone actually infringed our patent and no one would benefit except the lawyers.
/End rant. Sorry bout that.
In another mindset, though, I can assume Bill Gates just considers himself a smart ideas guy and wants to capitalize in the most efficient way on his ideas. Which is not intrinsically wrong, but complicates our world in the consequences. I doubt he sees these places as idea-destructive as they probably are, or else I don't think he would really be into it. Certainly, whatever residual greed and wealth desire he naturally has, is probably relatively diminished by now.
