here is the press release or whatever passes for one now... I don't see what they could have patented beyond the design. My main concern, looking now, is how material intensive it is. Those heat pipes are huge as they cover the whole exposed aperture. There are some black covers that may or may not be covering heat pipe material but even still the costs should be heroic - it is a copper one.
I'm jammed at work so finding the paper (if one exits) will have to wait. Check the comments - I'll add them there if and when I find it.
