What about Soyuz, gemini, skylab, or Apollo? Most of that technology should have gone out of patent if there was any. I know Lockheed has a lock on Orion for the moment, but that shouldn't mean we can't try. I just want the basics--enough for people willing to take the risk to go out and try to mine asteroids. I think if we can get that then things will snowball like they did with the USA.
