Let me get this straight, a company known for ripping off other peoples' designs and producing "knock offs" is going to sue apple because it kinda looks like one of their products?
If we can't go after companies in China for copywrite infringement (such as with movies, software, and device knock offs), how can they sue someone here in the US?
As far as the patentablility, they would have to have a US patent on a tablet device of specific dimensions and weight, and functionality. All of which would be difficult to patent at this time because the description would be too generic and because of similarities to other devices.
