In the latest major twist in this epic battle between wireless chipmakers, a US District Judge has slapped a permanent injunction on any products containing those Qualcomm 3G chips ruled to be infringing on Broadcom's so-called '686 patents.

At this point, with a voluntary licensing agreement seemingly off the table, the next move for Qualcomm is establishing a plan of action to show Judge James Selna how it plans to redesign its products into compliance.
