WiLAN has made a solid business out of suing the wireless industry over alleged patent violations, coaxing settlements out of HTC, Novatel and four other heavyweights. It won't get any money from Apple, though, as an Eastern District of Texas court has ruled that the iPhone maker didn't infringe on a WiLAN patent covering CDMA and HSPA data transmissions. The court also invalidated two claims in the patent, which makes it that much harder for WiLAN to sue others. Apple isn't completely out of the woods when the plaintiff is "reviewing its options." However, we suspect that the case doesn't have a leg to stand on -- especially not in a legal climate that's increasingly hostile toward patent trolls.
