United States Federal Circuit

Judgment for plaintiff finding defendants infringed on its patents related to its power converter systems is affirmed, where: 1) defendants did not prove any of the asserted claims of the '190 Patent, the '021 Patent, the '702 Patent or the '083 Patent, would have been anticipated or obvious at the time of invention; 2) the ’034 Patent is not entitled to the 1998 priority date; 3) the district court correctly construed "isolation" to require the absence of an electrical path between the input and output of a particular stage, component, or circuit, and thus partial summary judgment of infringement on this limitation was proper; 4) the district court did not err in its instruction on contributory infringement; 5) the record contained sufficient evidence to support the jury's conclusion that each defendant had actual knowledge of the patents in suit during the relevant time period; and 6) the district court did not abuse its discretion with regard to the multiple claims asserted by defendants with respect to the damages portion of the trial.
