Wish I had the patent on that. They're going to make a fortune. Invention is presently assigned to Univ. of Manchester; they'll probably license it. Patent Application Status: Dispatched from preexam; not yet docketed. In other words, it hasn't been examined for patentability yet. Univ. of Manchester not the only one working on graphene technology. Here's face page Univ. of Manchester's patent publication. http://images.investorshub.advfn.com/images/uploads/2012/1/26/hococGraphene_Publ_1.jpg
