Question for someone who knows something about patent law: does Rackspace have a chance of actually making any money here? Simply based on seeing other stories like this, it seems that all these trolls operate through shell companies, which can simply declare bankruptcy without (1) every paying any actual fees and (2) without hurting the parent. Is that true here as well?
