RIM case sent back to lower court
Simon Avery writes in The Globe and Mail:
Research In Motion Ltd. says it may appeal to the Supreme Court of the United States to review a ruling handed down by an appeals court this week affirming that the company infringed on several patents of a Virginia firm.
On Tuesday, the U.S. Court of Appeals for the Federal Circuit in Washington upheld most of its December patent infringement ruling against RIM.
But the court revised its original ruling to say the company, based in Waterloo, Ont., had infringed on seven of 16 claims of patents of NTP Inc., rather than 11 as originally determined. In a statement , RIM questioned the long-term validity of the seven remaining claims. Two of them have recently been rejected by the U.S. Patent and Trademark Office and the other five are under re-examination, RIM said.
