MMI Research Ltd v Cellxion Ltd & Ors

MMI Research Ltd v Cellxion Ltd & Ors

The patent is invalid for obviousness over the Fox article because, on the evidence, the skilled team would inevitably arrive at the claimed invention given the disclosure in Fox and their common general knowledge. The Judge erred in finding otherwise, as the evidence was all one way and the key step (using an out-of-area LAC with a fake base station to provoke IMSI disclosure) would be obvious to the skilled person.

The Judge erred in finding otherwise, as the evidence was all one way and the key step (using an out-of-area LAC with a fake base station to provoke IMSI disclosure) would be obvious to the skilled person.
