Last year Nokia revealed its current flagship model Lumia 920 running Windows Phone 8. Nokia Lumia 920 followed similar design language as Lumia 800 and Lumia 900. It has a unibody polycarbonate body with curved gorilla glass on the top. The device design was praised by many although some people criticized it for its thickness and weight. Nokia has recently won a patent for ornamental design of Lumia 920 handset in US through USPTO.
Hopefully (but probably not) the patent will allow Nokia to clamp down on the rampant cloning of the handset we have seen already.
