Those are innovative products yes, but in new/weak competition spaces. It's a different situation entirely when going head on against a huge competitive with an innovative product.
For example, a new, innovative, OS going against Windows. In this case and without software patents, Microsoft would just copy the features that make it special, leaving the R&D investment as a waste, unless software patents are available of course.

I'm not one of the downvoters, but I can speculate as to the reason:
Perhaps it's because you're using most likely a non-patented browser that fetches a non-patented hypertext format (HTML) via a non-patented application protocol (HTTP) built on a non-patented network stack (TCP) by connecting to a non-patented web server (HN) written in a non-patented programming language (Arc), and you're using this stack to argue that people have no motivation to innovate in software if patent protection is unavailable.
Or perhaps it's because you're trotting out that old argument that software patents can help the little guy compete against big players. But so far the only "little guy" success anyone can point to was Stac Electronics, a publicly traded company for whom a $9.7 million sales quarter was evidence of declining business. That's not little: http://articles.latimes.com/1994-06-22/business/fi-7159_1_pa...

Yeah, there seems to be a lot of that these days. People down-vote for disagreement, as opposed to just spammy posts. It's really kinda sad for a community that should be open to discussion and critical thought.
