The two companies warring over the popular BlackBerry device head for a courtroom showdown on Friday, when a judge begins weighing an injunction on the wireless email service. BlackBerry maker Research In Motion Ltd. has argued against the injunction, noting that the U.S. Patent and Trademark Office is poised to reject all of challenger NTP Inc.’s patents. Indeed, the agency this week rejected the first of five patents closely tied to the court case. U.S. District Judge James R. Spencer previously had said he was unwilling to delay his proceedings while awaiting final word from the agency. But the speedier moves from the patent office have some attorneys wondering whether Spencer will be swayed.
