Haemonetics Corp. v. Baxter Healthcare Corp.
Haemonetics Corp....(U.S. Fed. Cir., Drugs & Biotech, Health Law, Intellectual Property, Patent) In plaintiff’s suit for infringement of a patent, which claims a compact blood centrifuge device for separating and collecting components in a liquid such as blood, judgment of the district court is reversed in part, vacated in part, and remanded where: 1) district court’s claim construction is reversed as “centrifugal unit” in claim 16 consistently means a vessel and a plurality of tubes, irrespective of its meaning in claim 1; and 2) district court’s holding that claim 16 is not indefinite as a matter of law and the jury’s finding that the patent was not invalid due to anticipation or obviousness is vacated because the district court erred in its construction of “centrifugal unit” and because the jury’s verdict relied on the district court’s incorrect claim construction.
