In a hearing on Friday, U.S. District Judge James Spencer decided against issuing an immediate ruling on whether to impose an injunction that would shut down sales and service of the popular mobile email devices in the U.S. But what remains clear, he said, is that the jury verdict in NTP’s case against Research In Motion for patent infringement, nearly four years ago, “has not changed in any substantial or substantive way.” After nearly four hours of arguments from each company and the U.S. Justice Department, Spencer said he would take the matter under advisement and reveal his decision “as soon as reasonably possible.”
