Click to drag nodes. Dashed links are resolved suits; green links are licensing.
Thomson Reuters published a rather abysmal infographic showing the "bowl of spaghetti" that is current flurry of patent-related suits in the mobile communications industry. So, inspired by a comment by John Firebaugh, I remade the visualization to better convey the network. That company in the center? Yeah, it's the world's largest, so little wonder it has the most incoming suits.
