A Delaware federal judge has knocked out patent infringement claims against telecommunications giant Nokia Corp. over its alleged use of 11 patents underlying BlackBerry Ltd.’s 3G and 4G communications technology, finding no evidence that the parent company effectively controlled its subsidiaries.

U.S. District Judge Richard G. Andrews of the District of Delaware on Tuesday allowed BlackBerry to proceed with its direct infringement claims against Nokia’s American divisions but released the Finnish parent and its other subsidiaries from the 1-year-old suit alleging direct, willful and indirect infringement.
