Case Number: CLB0059

Date: 03.18.2004

Citation: 70 U.S.P.Q.2d 1209 (Fed. Cir. 2004)

In International Rectifier, the Federal Circuit held that claim terms must be construed in accordance with the ordinary and customary meaning assigned to them by those skilled in the art unless the specification either 1) sets forth a different meaning or 2) uses words that manifest a “clear disavowal of claim scope.” The Court vacated the District Court’s summary judgment of infringement and remanded the case back to the District Court for consideration consistent with the Federal Circuit’s claim interpretation.
