On December 4, 2014, the U.S. Court of Appeals for the Federal Circuit issued a decision in Ericsson v. D-Link, providing substantial guidance to lower courts on how to calculate royalty rates for standard-essential patents encumbered by a commitment to license on reasonable and nondiscriminatory terms.
