By Debbie Rosenbaum – Edited by Stephanie Young
Martek Biosciences Corp. v. Nutrinova Inc., 2008-1459, -1476 (CAFC Sept. 3, 2009)
On September 3, 2009, the Court of Appeals for the Federal Circuit affirmed the U.S. District Court for the District of Delaware’s jury verdict finding that Martek’s patents were valid and infringed, but reversed the points of error Martek asserted on cross appeal. The Federal Circuit (“CAFC”), sitting as an expanded five-member panel: 1) upheld the district court’s denial of Lonza’s motions for judgment as a matter of law (“JMOL”); 2) found that the district court’s exclusion of Lonza’s prior inventorship evidence was appropriate; 3) upheld the district court’s construction of the term “non-chloride sodium salt”; 4) reversed the district court’s finding that two claims of the ’567 patent were invalid as a matter of law; and 5) expanded the district court’s limited construction of the claim term “animal” in the ’244 patent to include humans.
