I have to say that, after waking up this morning, I realize my point about innovation is flawed. You cannot innovate on top of a patent, you are absolutely right. You can try to make something covered by a patent differently (and innovate in parallel) but then again, you do not even have to own the patent for that.
The rest of my point, that defensive patents are silly, is still valid. There's one kind of patent: offensive. You want to make money out of it (either by buying a patent you know you infringe upon or sue someone infringing). You cannot innovate with it (if you got the patent yourself you already innovated) and cannot retaliate against a patent troll since they don't have any products. That doesn't leave much "defensive" actions.
