"AMD put significant protections in place to protect its intellectual property (IP) and prevent valuable IP from being misused or reverse engineered to develop future generations of processors."
That being said, I wouldn't be surprised if they got the IP anyway, just that wasn't the intention. AMD CEO Lisa Su made some comments a few weeks ago that the joint venture was already dead in the water and was just for one project only. I get the feeling AMD wasn't too happy about the way it all turned out.
