SAN FRANCISCO — A Delaware federal judge has awarded exceptional case fees and costs against an Acacia subsidiary in a patent case that technology companies had argued was a poster child for fee shifting.

U.S. District Judge Gregory Sleet issued Thursday’s order under seal, so details were unclear. But Sunnyvale-based NetApp had been seeking $1.1 million in fees and $235,000 in costs, saying Acacia subsidiary Summit Data Systems had “double-dipped” by bringing lawsuits over products it had already licensed via patent aggregator RPX Corp.
