But it's still trade secrets. I can tell you most companies will not patent the processes etc. that are crucial to their business, because they know that the knowledge in those is worth much more than the patents would be (it gives them a big a competitive advantage). Instead they patent the ideas behind their products in an as broad as possible manner so that nobody can actually know what they actually do and that it covers nearly every possible variations. That's why with the current system we are left with the worst of both worlds.
