IXYS announced that the United States Court of Appeals for the Federal Circuit issued a ruling on Monday constituting complete victory for IXYS in its ongoing patent dispute with International Rectifier. The appellate court ruled in favor of IXYS on all remaining claims of infringement, stating that “IXYS is entitled to entry of final judgment in its favor as to all claims.”

In response to the court ruling, International Rectifier’s Graham Robertson, vice president of global marketing and corporate communications, stated, “We are disappointed with the Court’s decision. We are in the process of reviewing this decision and determining a course of action”.
