RIM had just been named as a defendant in another patent struggle. Thus time we have yet another notorious patent troll Wi-Lan sing RIM. RIM is not alone in this with Wi-Lam targeting practically every one with their patent infringement allegations. They are suing over U.S. Patent No. 6,260,168 which covers Bluetooth implementations so anything with Bluetooth is fair game. It looks like this patent madness is just going to get worse.
