but if you find the mechanics they are using in other, pre-existing d20 products by other companies, or within the OGL itself there is not much they can do about it.

Of course there is. They can challenge the OGL itself (I can think of two legal means of doing that), for instance. I am not saying they'd win, or that it would be easy. I am saying there are grounds to try, and they have a lot of money backing them. I don't think anyone wants to wake that sleeping giant. It was one thing to support an edition they already abandoned. It's entirely another to try and directly strongly challenge them with the stuff they just spent the last two years developing and playtesting. That would result in, at best, a costly and long lawsuit I think.
I think a couple small guys might be able to get away with it. But Paizo doing it? No, I do not think that would go well. Gloves would come off at that point.
