Updated from 1:41 p.m. EDTHere we go again: For the second time in three weeks, Research In Motion ( RIMM) was hit with an adverse court ruling. As with the earlier decision, the ruling involved a fairly routine procedural motion in a long-running patent dispute with NTP, an intellectual property holding company. In Friday's ruling, an appeals court denied RIM's request to delay sending the case back to a lower court while the U.S. Supreme Court decided whether to take the case. Although routine, the decision does mean that RIM could be one step closer to being barred from offering its BlackBerry email service in the U.S. The district court that will re-hear the case already ruled to that effect when it originally heard the case. Although the appeals court overturned that injunction, the district court could reinstate it this second time around. NTP is confident in its position with the case at both the Supreme Court and district court levels, said Kevin Anderson, an attorney with Wiley Rein & Fielding, which represents NTP. "We're eager to get the proceedings resolved at both courts," he said. In a statement, RIM said it will ask the Supreme Court to stay the case while the court is determining whether to accept RIM's appeal. "While further review by the Supreme Court is generally uncommon, RIM continues to believe this case raises significant national and international issues warranting further appellate review," the company said in the statement. Representatives for RIM did not return calls seeking further comment. Investors appeared to assume the worst as the stock plunged immediately before 11:14 a.m. EDT, when Nasdaq halted trading in the stock. At the time of the halt, the stock was off $3.54, or 5.5%, to $61.12. Following its return to trading, shares climbed higher and were recently down only $1.26, or 2%, to $63.40.
