The Federal Circuit Court of Appeals has denied a petition for panel rehearing and rehearing en banc in 10-year-old litigation that concluded with the court allowing a U.S. Patent and Trademark Office (USPTO) reexamination to decide patent-infringement issues pending in district court. Fresenius USA, Inc. v. Baxter Int’l, Inc., Nos. 2012-1334, 1335 (Fed. Cir. Nov. 5, 2013). The Fresenius chronology and the implications of the court ruling to which the petition pertains are detailed in Shook, Hardy & Bacon’s IpQ newsletter, prepared by IP Partner Peter Strand. Several jurists penned dissenting statements to the latest ruling, complaining that the lower court’s resolution of validity issues was final and should not have been disturbed as to these litigants by the later USPTO determination.
