Bayer Intellectual Property Gmbh v. Warner Chilcott Company, LLC

United States District Court, D. Delaware

April 21, 2015



GREGORY M. SLEET, District Judge.


The plaintiffs Bayer Intellectual Property GmbH and Bayer Pharma AG (collectively, "Bayer") filed this patent infringement lawsuit against defendants Warner Chilcott Company, LLC, Warner Chilcott (US), LLC, and Warner Chilcott plc (collectively, "Warner Chilcott") on August 13, 2012. (D.I. 1.) Bayer alleges infringement of U.S. Patent No. 5, 980, 940 ("the '940 Patent").[1] Presently before the court is Warner Chilcott's motion for summary judgment on the grounds that the '940 Patent is indefinite and therefore invalid. (D.I. 131.) For the reasons that follow, the court will grant Warner Chilcott's motion for summary judgment.


The '940 Patent claims an oral contraception regimen in which two hormones are taken at set time points throughout the dosing schedule. See, e.g., '940 Patent, claim 1. Bayer alleges that Warner Chilcott's product Lo Loestrin infringes the '940 Patent's claims.

The parties sought construction of the claim term: "high contraceptive reliability, low incidence of follicular development, and satisfactory cycle control, with reliable avoidance of intracyclic menstrual bleeding and undesirable side-effects" (the "disputed term"). '940 Patent, claims 1, 8 & 10. In its October 9, 2014, Claim Construction Order, the court found that it was "unable to construe the disputed phrase." (D.I. 120 at 3.) In particular, the court found that the words of degree - i.e., "high, " "low, " "satisfactory, " and "reliable"-had no standards against which to draw comparisons, and the patent offered no suggestions for how to measure these criteria. (Id. at 7-8.) "The court is left at an impasse and is unable to discern the meets and bounds of the asserted claims." (Id. at 8.) As a result, the court indicated that summary judgment would be the proper avenue to address an indefiniteness challenge. (Id. )


Under Federal Rule of Civil Procedure 56(c), summary judgment is appropriate "if the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, show that there is no genuine issue as to any material fact and that the moving party is entitled to a judgment as a matter of law." See also Celotex Corp. v. Catrett, 477 U.S. 317, 322 (1986). The moving party bears the burden of proving that no genuine issue of material fact exists. Matsushita Elec. Indus. Co., Ltd. v. Zenith Radio Corp., 475 U.S. 574, 585 n.10 (1986). A fact is material if it "could affect the outcome" of the proceeding. Lamont v. New Jersey, 637 F.3d 177, 181 (3d Cir. 2011). There is a genuine issue "if the evidence is sufficient to permit a reasonable jury to return a verdict for the non-moving party." Id. When determining whether a genuine issue of material fact exists, the district court must view the evidence in a light most favorable to the nonmoving party and draw inferences in that party's favor. Wishkin v. Potter, 476 F.3d 180, 184 (3d Cir. 2007). If the moving party is able to demonstrate an absence of disputed material facts, the nonmoving party must then "come forward with specific facts showing that there is a genuine issue for trial.'" Matsushita, 475 U.S. at 587 (citing Fed.R.Civ.P. 56(e)).

Patent invalidity on indefiniteness grounds requires proof by clear and convincing evidence. See 35 U.S.C. § 282 ("A patent shall be presumed valid."); Microsoft Corp. v. i4i Ltd. P'ship, 131 S.Ct. 2238 (2011) ("We consider whether§ 282 requires an invalidity defense to be proved by clear and convincing evidence. We hold that it does.").


The law of patent definiteness has its roots in 35 U.S.C. § 112: "The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention." § 112 (emphasis added). In light of this statutory mandate, "a patent is invalid for indefiniteness if its claims, read in light of the specification delineating the patent, and the prosecution history, fail to inform, with reasonable certainty, those skilled in the art about the scope of the invention." See Nautilus, Inc. v. Biosig Instruments, Inc., 134 S.Ct. 2120, 2124 (2014) (emphasis added). Claims may be found invalid as indefinite when they fail to specify clear, definite boundaries or standards. See Interval Licensing LLCv. AOL, Inc., 766 F.3d 1364, 1371 (Fed. Cir. 2014) ("The claims, when read in light of the specification and the prosecution history, must provide objective boundaries for those of skill in the art.").

The court has already explained in its Claim Construction Order that the intrinsic record fails to assign meaning to the words of degree in the disputed term. (D.I. 120 at 3-8.) Bayer did not seek reconsideration of this ruling, and the court need not revisit its reasoning. Nonetheless, Bayer contends that the disputed term is not indefinite because one skilled in the art would understand-with reasonable certainty-its meaning, as demonstrated by extrinsic evidence. Bayer provides dozens of pieces of extrinsic evidence, as well as a supplemental declaration from Dr. Lee Shulman, in support of a new argument that the disputed term and the words of degree simply indicate that the claimed invention performs comparably to other oral contraceptives on the market.[2] ( See, e.g., D.I. 135.)

As an initial matter, the court takes issue with Bayer's procedure in making its arguments. As even Bayer highlights in its brief, the court gave counsel an opportunity during the Markman hearing to explain why extrinsic evidence was necessary to construe the terms-Bayer conceded that the evidence was merely for "context." (D.I. 134 at 3; D.I. 84 at 17 ("Our position is the meaning is clear from the text of the claim itself, and that it will be understood by a person of skill in the art.... It [extrinsic evidence] is simply meant to provide the context....").) At this stage, however, Bayer contends that extrinsic evidence and expert testimony is indeed required to understand the disputed term for the purposes of an indefiniteness inquiry. Notwithstanding the fact that Bayer knew about Warner Chilcott's indefiniteness defense at the time of the Markman hearing, the court fails to understand Bayer's argument that different analyses apply; depending on whether the court is construing terms versus assessing definiteness-they are two sides of the same coin. See Noah Sys., Inc. v. Intuit Inc., 675 F.3d 1302, 1311 (Fed. Cir. 2012) ("Whether a claim complies with the definiteness requirement of 35 U.S.C. § 112 ¶ 2 is a matter of claim construction").

Moreover, during the October 31, 2014, teleconference, the court explained that additional extrinsic evidence would ...
