I don't believe it has much to do with patents, though I suppose it helps. They have the talent, existing knowledge and the manufacturing capabilities to make it happen. One machine, which kind of looks like a CNC machine to me, can cost $200-400million IIRC. Another way to look at it, China would love to be able to copy their processes and has not yet been able to do so.
