`
`IN THE UNITED STATES DISTRICT COURT
`FOR THE DISTRICT OF DELAWARE
`
`· HOSPIRA, INC.,
`
`Plaintiff,.
`
`v.
`
`AMNEAL PHARMACEUTICALS LLC,
`
`Defendant.
`
`Civil Action No. 15-697-RGA
`
`MEMORANDUM ORDER
`
`· Presently before the Court is the issue of claim construction of multiple terms in U.S .
`
`. Patent Nos. 8,242, 158 ("the '158 patent"); 8,338,4 70 ("the '4 70 patent"); 8,455,527 ("the '527
`
`patent"); and 8,648, 106 ("the '106 patent") (collectively "the patents-in-suit"). The Court has
`
`considered the parties' Joint Claim Construction Brief. (D.I. 44).
`
`"It is a bedrock principle of patent law that the claims of a patent define the invention to
`
`which the patentee is entitled the right to exclude." Phillips v. A WH C01p., 415 F.3d 1303, 1312
`
`(Fed. Cir. 2005) (en bane) (internal quotation marks omitted). '"[T]here is no magic formula or
`
`catechism for conducting claim construction.' Instead, the court is free to attach the appropriate
`
`weight to appropriate sources 'in light of the statutes and policies that inform patent law.'"
`
`Soft View LLC v. Apple Inc., 2013 WL 4758195, at *1 (D. Del. Sept. 4, 2013) (quoting Phillips,
`
`415 F.3d at 1324). When construing patent claims, a court considers the literal language of the
`
`claim, the patent specification, and the prosecution history. Markman v. Westview Instruments,
`
`Inc., 52 F.3d 967, 977-80 (Fed. Cir. 1995) (en bane), aff'd, 517 U.S. 370 (1996). Of these
`
`sources, "the specification is always highly relevant to the claim construction analysis. Usually,
`

`
`it is dispositive; it is the single best guide to the meaning of a disputed term." Phillips, 415 F.3d
`
`at 1315 (internal quotation marks and citations omitted).
`
`"[T]he words of a claim are generally given their ordinary and customary meaning ....
`
`[Which is] the meaning that the term would have to a person of ordinary skill in the art in
`
`question at the time of the invention, i.e., as of the effective filing date of the patent application."
`
`Id. at 1312-13 (internal quotation marks and citations omitted). "[T]he ordinary meaning of a
`
`claim term is its meaning to [an] ordinary artisan after reading the entire patent." Id. at 1321
`
`(internal quotation marks omitted). "In some cases, the ordinary meaning of claim language as
`
`understood by a person of skill in the art may be readily apparent even to lay judges, and claim
`
`construction in such cases involves little more than the application of the widely accepted
`
`meaning of commonly understood words." Id. at 1314 (internal citations omitted).
`
`When a court relies solely upon the intrinsic evidence-the patent claims, the
`
`specification, and the prosecution history-the court's construction is a determination of law.
`
`See TevaPharms. USA, Inc. v. Sandoz, Inc., l-35 S. Ct. 831, 841 (2015). The court may also
`
`make factual findings based upon consideration of extrinsic evidence, which "consists of all
`
`evidence external to the patent and prosecution history, including expert and inventor testimony,
`
`dictionaries, and learned treatises." Phillips, 415 F.3d at 1317-19 (internal quotation marks and
`
`citations omitted). Extrinsic evidence may assist the court in understanding the underlying
`
`technology, the meaning of terms to one skilled in the art, and how the invention works. Id.
`
`Extrinsic evidence, however, is less reliable and less useful in claim construction than the patent
`
`and its prosecution history. Id.
`
`"A claim construction is persuasive, not because it follows a certain rule, but because it
`
`defines terms in the context of the whole patent." Renishaw PLC v. Marposs Societa 'per
`

`
`
`
`Case 1:15-cv-00697-RGA Document 57 Filed 05/25/16 Page 3 of 5 PageID #: 891
`
`Azioni, 158 F.3d 1243, 1250 (Fed. Cir. 1998). It follows that "a claim interpretation that would
`
`exclude the inventor's device is rarely the correct interpretation." Osram GmbH v. Int'! Trade
`
`Comm 'n, 505 F.3d 1351, 1358 (Fed. Cir. 2007) (internal quotation marks and citation omitted).
`
`The parties agree that the term "effective amount," found in claim 1 of the '527 patent,
`
`should be construed as "amount sufficient to produce the desired effect." (D.I. 44 at p. 4). The
`
`Court adopts this construction.
`
`The parties dispute the construction of four terms: (1) "dexmedetomidine;" (2) "no more
`
`than about 2% decrease in the concentration of dexmedetomidine;" (3) "critically ill;" and ( 4)
`
`"intensive care unit." (Id.). The Court addresses each term separately.
`
`1.
`
`"dexmedetomidine" (all asserted claims)
`
`Plaintiff's proposed construction: "substantially pure; optically active
`a.
`dextrorotary stereoisomer of medetomidine, as the free base or pharmaceutically
`acceptable salt"
`
`b.
`Defendant's proposed construction: "substantially pure, optically active
`dextrorotary stereoisomer ofmedetomidine, as the.free base"
`
`Court's construction: "substantially pure, optically active dextrorotary
`c.
`stereoisomer ofmedetomidine, as the free base or pharmaceutically acceptable
`salt"
`
`The specification of each of the patents-in-suit sets forth an explicit definition for this
`
`term. See, e.g., '158 patent at 3:21-24. That definition aligns with Plaintiff's proposed
`
`construction. "When a patentee explicitly defines a claim term in the patent specification, the
`
`patentee's definition controls." Martek Biosciences Corp. v. Nutrinova, Inc., 579 F.3d 1363,
`
`1380 (Fed. Cir. 2009). Thus, here, the inventor's lexicography governs. I therefore construe
`
`"dexmedetomidine" to mean "substantially pure, optically active dextrorotary stereoisomer of
`
`medetomidine, as the free base or pharmaceutically acceptable salt."

`
`"no more than about 2% decrease in the concentration of dexmedetomidine"
`2.
`(' 106 patent, claim 1)
`
`a.
`
`b.
`
`c.
`
`Plaintiff's proposed construction: Plain meaning
`
`Defendant's proposed construction: Indefinite
`
`Court's construction: Plain meaning
`
`A patent must "inform those skilled in the art about the scope of the invention with
`
`reasonable certainty." Nautilus, Inc. v. Biosig Instruments, Inc., 134 S. Ct. 2120, 2129 (2014).
`
`Defendant's first indefiniteness argument depends on its proposed construction of
`
`"dexmedetomidine." Since the Court rejected that construction, this argument is also rejected.
`
`Defendant's second argument focuses on the word "about." "When 'about' is used as part of a
`
`numeric range, ... [that use] avoids a strict numerical boundary to the specified parameter [and]
`
`[i]ts range must be interpreted in its technologic and stylistic context."' Cohesive Techs., Inc. v.
`
`Waters Corp., 543 F.3d 1351, 1368 (Fed. Cir. 2008) (quoting Pall Corp. v. Micron Separations,
`
`Inc., 66 F.3d 1211, 1217 (Fed. Cir. 1995)). The '106 patent's specification explains that "'about'
`
`... as used herein means within an acceptable errorrange for the particular value as determined
`
`by one of ordinary skill in the art." '106 patent at 5:31-33. The specification further states that
`
`this "will depend in part on how the value is measured or determined, i.e., the limitations of the
`
`measurement system." Id. at 5:33-35. In context, a PHOSITA would understand the scope of the
`
`"about" limitation with reasonable certainty. Therefore, Defendant's indefiniteness argument is
`
`rejected. The term is afforded its plain and ordinary meaning.
`
`3.
`
`"critically ill" ('527 patent, claim 10)
`
`a.
`
`b.
`
`c.
`
`Plaintiff's proposed construction: Plain meaning
`
`Defendant's proposed construction: Indefinite
`
`Court's construction: Plain meaning

`Case 1:15-cv-00697-RGA Document 57 Filed 05/25/16 Page 5 of 5 PageID #: 893
`
`"' [A] patentee need not define his invention with mathematical precision in order to
`
`comply with the definiteness requirement."' Interval Licensing LLC v. AOL, Inc., 766 F.3d 1364,
`
`1370 (Fed. Cir. 2014) (quoting Invitrogen Corp. v. Biocrest Mfg., L.P., 424 F.3d 1374, 1384 (Fed.
`
`Cir. 2005)). The term "critically ill" has a recognizable meaning to those having skill in the art.
`
`Further, the '527 patent provides examples of medical conditions that may satisfy the "critically
`
`ill" limitation. '527 patent at 10:62-11:1. Therefore, Defendant's indefiniteness argument is
`
`rejected. The term is afforded its plain and ordinary meaning.
`
`4.
`
`"intensive care unit" ('527 patent, claim 8)
`
`. Plaintiff's proposed construction: "any setting that provides care to
`a.
`critically ill patients, typically characterized by high nurse-to-patient ratios,
`continuous medical supervision, and intensive monitoring"
`
`Defendant's proposed construction: "any setting that provides intensive
`
`b.
`care"
`
`Court's construction: Either "any setting that provides care to critically ill
`c.
`patients" or "any setting that provides intensive care"
`
`The latter part of Plaintiff's proposed construction-"typically characferized by high
`
`nurse-to-patient ratios, continuous medical supervision, and intensive monitoring"-is rejected.
`
`This language finds no support in the intrinsic record. I cannot discern any material distinction
`
`between "any setting that provides care to critically ill patients" and "any setting that provides
`
`intensive care." I therefore decline to construe the term further at this time. The parties are
`
`permitted to bring up any additional arguments pertaining to this term at the pretrial conference.
