GOOD NEWS FOR RIM: A U.S. judge has overturned a multimillion-dollar patent-infringement verdict against BlackBerry maker Research In Motion. The judge determined that Mformation Technologies Inc., which makes software for managing mobile devices, failed to show that RIM infringed on a key patent in question.

PREVIOUS AWARD: A federal jury had awarded Mformation $147.2 million last month based on an infringement finding.
