A rough year for the U.S. Court of Appeals for the Federal Circuit got rougher on Monday, when two more of its rulings were unanimously reversed by the U.S. Supreme Court.

The more stinging rebuke came in Limelight Networks v. Akamai Technologies, a decision addressing liability for inducing others to infringe a patent. The Supreme Court held that there can’t be induced infringement without a finding that some party directly infringed the patent.
