This is what I am interested in as well. How is it that UW is certain the A7 infringed but not the A6? Can the A7 be reverse engineered to figure out how it works? Does UW have the technology to do that? Even if they did get that far, how did they determine that the implementation is the same? I admit I don't have the patience to read up the patents, but I'm looking forward to the discussions here.
