Why Rackspace Is Suing The Most Notorious Patent Troll In America
Our dealings with this particular troll reach back to December 2010 when IP Navigation Group (IP Nav), as agent for a supposedly secret patent owner, now known as Parallel Iron, accused Rackspace of patent infringement. IP Nav told us that they could not divulge the details of their infringement claims – not even the patent numbers or the patent owner – unless we entered into a “forbearance agreement” – basically, an agreement that we would not sue them. IP Nav was worried that as soon as we found out what their patents and claims actually were, Rackspace would sue to invalidate their patents or for a declaration that Rackspace does not infringe.
