Ledergerber Medical Innovations, LLC, and v. W.L. Gore & Associates

April 26, 2011


The opinion of the court was delivered by: Judge Virginia M. Kendall


Plaintiffs Ledergerber Medical Innovations, LLC and Dr. Walter Ledergerber (collectively "Ledergerber") move to reconsider the Court's invalidation of United States Patent No. 6,921,418 ('418 patent). Defendant W.L. Gore & Associates, Inc. ("Gore") seeks its attorney fees, asserting this case is "exceptional" under 35 U.S.C. § 285. For the reasons below, the Court denies both motions. As the Court found when it granted summary judgment to Gore, Ledergerber's § 120 priority claim is defective and, consequently, the '418 patent is anticipated under 35 U.S.C. § 102(b) by Ledergerber's prior-issued patents. Because there is insufficient evidence under the totality of the circumstances to declare this case exceptional, Gore is not entitled to attorney fees.


On March 19, 2001, Ledergerber filed patent application 09/813,091 ('091 application), which issued on July 26, 2005 as the '418 patent, titled "Dual-Sided, Texturized Biocompatible Structure." The '418 patent claims priority under 35 U.S.C. § 120 to a patent application Ledergerber filed on December 22, 1987. Gore manufactures and sells the PRECLUDE MVP, a medical implant covering that Ledergerber claims infringes on that '418 patent. The Court construed the meanings of disputed claim terms of the '418 patent after holding Markman hearings. (Doc. 131.) The Court subsequently granted Gore's motion for summary judgment on the grounds that the '418 patent was invalid. (See Doc. 184.) The Court found that the '418 patent did not receive the benefit of the 1987 filing date, and consequently, the '418 patent was anticipated under § 102(b) by another Ledergerber patent. Ledergerber now moves for reconsideration of that invalidity order (Doc. 189), and Gore seeks its attorney fees under § 285 (Doc. 194).


Though Federal Circuit precedent generally controls in patent cases, district courts apply the legal standard of their regional circuit on Rule 59(e) motions to reconsider. Minton v. NASD, Inc., 336 F.3d 1373, 1378--79 (Fed. Cir. 2003). A motion to reconsider allows the movant to bring to the Court's attention manifest errors of law or fact or newly discovered evidence. United States v. Resnick, 594 F.3d 562, 568 (7th Cir. 2010). They are granted on a showing of "manifest error," which is the "wholesale disregard, misapplication, or failure to recognize controlling precedent." Oto v. Metro. Life Ins. Co., 224 F.3d 601, 606 (7th Cir. 2000). A Rule 59(e) motion, however, is not a "vehicle for a party to undo its own procedural failures, and it certainly does not allow a party introduce new evidence or advance arguments that could have, and should have, been presented to the district court prior to the judgment." Resnick, 594 F.3d at 568.

In exceptional patent cases, courts have discretion to award reasonable attorney fees to the prevailing party. 35 U.S.C. § 285. Whether a case is "exceptional" must be established by "clear and convincing evidence." Beckman Instruments, Inc. v. LKB Produkter AB, 892 F.2d 1547, 1551 (Fed. Cir. 1989). When assessing whether a case qualifies as exceptional, district courts must look at the "totality of the circumstances." Yamanouchi Pharm Co., Ltd. v. Danbury Pharmacal Inc., 231 F.3d 1339, 1347 (Fed. Cir. 2000). The decision to award reasonable attorney fees rests in the discretion of the district court. Superior Fireplace Co. v. Majestic Prods. Co., 270 F.3d 1358, 1376 (Fed. Cir. 2001).


In his motion to reconsider, Ledergerber argues that § 120, as a matter of statutory interpretation, does not require continuity of disclosure, and the Court did not consider the testimony of a patent examiner and two of Ledergerber's experts. The Court addresses each of these arguments before turning to Gore's motion for attorney fees.

A. Continuity of Disclosure

Ledergerber first argues that the judgment of invalidity is improper because § 120 does not require the continuity of disclosure. When it invalidated the '418 patent, the Court noted that "continuity of disclosure must be maintained through the chain of patents leading up to the patent-in-suit," and that disclosure "must 'contain a written description of the invention' sufficient to 'enable any person skilled in the art to which it pertains . . . to make and use the same.'" (Doc. 184 at 9); see also Zenon Envtl., Inc. v. U.S. Filter Corp., 506 F.3d 1370, 1378 (Fed. Cir. 2007) (finding "[i]n order to gain the benefit of the filing date of an earlier application under 35 U.S.C. § 120, each application in the chain leading back to the earlier application must comply with the written description requirement of 35 U.S.C. § 112."); 35 U.S.C. § 112 ¶ 1 (requiring "a written description of the invention" sufficient to "enable any person skilled in the art to which it pertains . . . to make and use the same.") The Court then found that Ledergerber did not have this continuity of disclosure because an earlier application in the chain did not explicitly disclose the ePTFE sheet claimed by the '418 patent and did not incorporate previous applications in Ledergerber's chain. (See Doc. 184 at 11-14.)

According to Lederger, § 120, by its express terms, does not require continuity of disclosure, "namely that each application in a chain must contain a written description of the claimed invention," but rather "only . . . § 120 support in the application from which priority is being claimed." (Doc. 189.) To receive an earlier priority date, § 120 requires, among other things, that "an invention disclosed [was] in the manner provided by the first paragraph of section 112 of this title in an application previously filed in the United States." 35 U.S.C. § 120. Ledergerber asserts that the "an" in the words "an application" should not construed to mean "all."

Put simply, Ledergerber's contention is at odds with long precedent that binds this Court. See e.g., Zenon, 506 F.3d at 1378; Lockwood v. Am. Airlines, Inc., 107 F.3d 1565, 1571 (Fed. Cir. 1997) (same); In re Schneider, 481 F.2d 1350, 1356 (C.C.P.A. 1977) (finding § 120 requires "continuous chain of co-pending applications each of which satisfies requirements of § 112 with respect to claimed subject matter"). In his reply, Ledergerber "recognizes the authority and effect" of the decisions requiring continuity of disclosure, but "submits that these decisions may need to be reconsidered or harmonized by the Federal Circuit in view of the guidance" from the Supreme Court in Bilski v. Kappos, 130 S. Ct. 3218 (2010) on legislative interpretation. (Doc. 197.) However, Bilski does not interpret § 120 and Ledergerber's argument should be addressed to the Federal Circuit on appeal, not this Court on reconsideration. The Court ...
