    OPINION
    CAMPBELL-SMITH, Chief Judge
    Plaintiff CANVS Corporation (CANVS) holds U.S. Patent No. 6,911,652 (filed
    June 28, 2005) (the ’652 patent), which is directed toward a low-light imaging device for
    use in military applications. See Compl. for Patent Infringement (Complaint or Compl.),
    Docket Number (Dkt. No.) 1, ¶ 31; see also Def.’s Mot. for Summ. J. of Invalidity of All
    Claims of the Patent-in-Suit (defendant’s Motion or Def.’s Mot.), Dkt. No. 59, Ex. A
    (’652 patent). Plaintiff brought this action pursuant to 28 U.S.C. § 1498(a) (2006) to
    recover compensation for the government’s alleged unlawful use or manufacture of the
    invention covered by the ’652 patent. Compl. 1; cf. 28 U.S.C. § 1498(a) (providing a
    cause of action for patent infringement by the government).
    1
    The Complaint for Patent Infringement (Complaint or Compl.), Docket Number
    (Dkt. No.) 1, filed by plaintiff CANVS Corporation (plaintiff or CANVS) is organized
    into numbered paragraphs with the exception of an introductory section. See Compl.
    passim. The court provides paragraph numbers when citing the numbered paragraphs
    and page numbers when citing the introductory section of the Complaint.
    Defendant has moved for summary judgment on its affirmative defense of
    invalidity, contending that each claim of the ’652 patent is anticipated by U.S. Patent No.
    5,035,472 (filed July 30, 1991) (the Hansen patent or the Hansen device), pursuant to 35
    U.S.C. § 102(e) (2006).2 Def.’s Mot. 1; see also 
    id. Ex. B
    (Hansen patent). In the
    alternative, defendant contends that claims two and three of the ’652 patent are rendered
    invalid as obvious by the combination of the Hansen patent and a second prior art
    reference. 
    Id. at 23–24.
    Defendant asserts that “the testimony of plaintiff’s expert
    [witness], Mr. [James Brian] Gillespie, should be ignored by the court because it has been
    proven unreliable.” Def.’s Reply in Supp. of its Mot. for Summ. J. of Invalidity of all
    Claims of the Patent-in-Suit (defendant’s Reply or Def.’s Reply), Dkt. No. 69, at 23
    (emphasis and some capitalization omitted).
    The central issue to be resolved on summary judgment is whether the earlier-
    issued Hansen patent anticipates the independent brightness adjustment feature of the
    ’652 patent. See infra Part III.A.2 (discussing the parties’ arguments with respect to this
    issue). Both the Hansen patent and the ’652 patent contain two types of imaging
    assemblies: (1) an image intensifier, which amplifies dim light and near-infrared energy;
    and (2) a thermal imager, which detects the far-infrared thermal signature of warm
    objects, such as human beings. See infra Part I.A–B (describing these assemblies). The
    ’652 patent also describes a mechanism for independently adjusting the output brightness,
    or intensity, of the two imaging assemblies, which allows a user to determine how much
    of the final viewed image is made up of output from the respective imaging assemblies.
    See infra Part I.A.
    Relying on the testimony of its expert witness, Mr. Gillespie, as to how the
    Hansen patent would be interpreted by a person of ordinary skill in the art as well as the
    testimony of its fact witness, Mr. Roland G. Dumais, Jr., as to the capabilities of the night
    vision systems in the Army’s possession at the relevant time,3 plaintiff contends that the
    2
    On September 16, 2011, section 102 and section 103 of title 35 of the United
    States Code were amended by the Leahy-Smith America Invents Act, Pub. L. No. 112-
    29, sec. 3(b)–(c), §§ 102–03, 125 Stat. 284, 285–87 (2011) (to be codified, in relevant
    part, at 35 U.S.C. §§ 102–03). The relevant amendments are applicable only to patents
    and patent applications with effective filing dates on or after March 16, 2013, see 
    id. sec. 3(n)(1),
    125 Stat. at 293, and are therefore inapplicable to this dispute, see Def.’s Mot. for
    Summ. J. of Invalidity of All Claims of the Patent-in-Suit (Def.’s Mot.), Dkt. No. 59, Ex.
    A (U.S. Patent No. 6,911,652 (filed June 28, 2005) (the ’652 patent)); 
    id. Ex. B
    (U.S.
    Patent No. 5,035,472 (filed July 30, 1991) (the Hansen patent or the Hansen device)).
    3
    Plaintiff also relies on the testimony of Mr. Roland G. Dumais, Jr. to address
    topics that are not appropriately addressed by lay witnesses. See, e.g., Pl. CANVS
    Corp.’s Opp’n to the Def.’s Mot. for Summ. J. of Invalidity (Pl.’s Resp.), Dkt. No. 66, at
    10, 13 (quoting Mr. Dumais’ interpretation of the Hansen patent); 
    id. at 2
    (quoting Mr.
    Dumais’ statement that CANVS “is entitled to compensation” (internal quotation marks
    omitted)); cf. 
    id. at 13
    (stating that Mr. Dumais is “clearly an expert in the area of fused
    2
    Hansen patent does not anticipate the independent brightness adjustment feature. See Pl.
    CANVS Corp.’s Opp’n to the Def.’s Mot. for Summ. J. of Invalidity (plaintiff’s
    Response or Pl.’s Resp.), Dkt. No. 66, at 8–9. Defendant contends that the Hansen patent
    does anticipate this feature, relying on the testimony of its expert witness, Dr. Allen M.
    Waxman, as to the correct interpretation of the Hansen patent. Def.’s Mot. 14–16
    (applying Dr. Waxman’s interpretation of the Hansen patent); Def.’s Reply 14 (same); cf.
    Def.’s Mot. Ex. E (Waxman Aff. ¶¶ 9–10) (contending that the Hansen patent discloses
    independent brightness adjustment).
    Before the court are: defendant’s Motion, filed March 12, 2013; plaintiff’s
    Response, filed May 17, 2013; defendant’s Reply, filed July 12, 2013; and Plaintiff’s
    Sur-Reply (Pl.’s Sur-Reply), Dkt. No. 78, filed by leave of the court on September 5,
    2013. Oral argument was conducted on September 18, 2013.4 This matter was
    transferred to the undersigned on October 18, 2013. Order of Oct. 18, 2013, Dkt. No. 79.
    For the following reasons, defendant’s motion is GRANTED-IN-PART and DENIED-
    IN-PART.
    I.     Background
    A.     The ’652 Patent
    The ’652 patent is directed toward a “low light imaging device” with two imaging
    assemblies: an image intensifier and a thermal imager.5 Def.’s Mot. Ex. A (’652 patent)
    night vision technology”). Because Mr. Dumais was not disclosed as an expert witness in
    this matter, the court disregards such testimony by Mr. Dumais.
    4
    The oral argument was recorded by the court’s Electronic Digital Recording
    system (EDR). The times noted in the oral argument citations refer to the EDR.
    5
    The thermal imagers and image intensifiers of interest in this motion have various
    names. See, e.g., Def.’s Mot. Ex. A (’652 patent) [57] (referring to a “thermal imaging
    assembly” and an “image intensification assembly”); 
    id. Ex. B
    (Hansen patent) col.3
    l.57–60 (referring to a “far infrared spectrum processing means” and a “near infrared
    processing means”). Because the parties use many of these terms interchangeably and
    identify no material difference between them, the court understands the terms to be
    synonymous for purposes of the present motion. See, e.g., Def.’s Mot. 12–13
    (contending that, like the ’652 patent, “[the] Hansen [patent] discloses a ‘thermal imaging
    assembly’” and “‘an image intensification assembly’” (emphasis omitted)); Pl.’s Resp. 10
    (using the terminology of the ’652 patent to identify element 28 of the Hansen patent as
    “the image intensifier tube” and elements 18, 24 and 26 as “the thermal imager”); Oral
    Argument of Mr. Joseph J. Zito at 10:14:45–58 (colloquy between the court and Mr.
    Zito) (agreeing—using the terminology employed in the Hansen patent—that the ’652
    patent allows independent adjustment of the near-infrared and far-infrared imaging
    assemblies); cf. 
    id. at 10:10:52–11:56
    (agreeing that an image intensification assembly
    3
    [57]. The output brightness of each imaging assembly can be adjusted independently so
    that each assembly provides more or less of the output image viewed by the user.6 See
    
    id. According to
    the ’652 patent’s specification, the image intensifier “amplif[ies] . . .
    photons in order to generate an enhanced photon based image.” 
    Id. col.4 l.44–45.
    The
    thermal imager “is preferably of a class of imaging assemblies which are able to detect or
    identify thermal energy emitted or radiated by a particular object” and “preferably
    includes an infrared imaging device,” commonly known as a “forward looking infrared
    device[].” 
    Id. col.4 l.12–21.
    The independent adjustments are intended to allow the user to take advantage of
    the benefits of both types of imaging assemblies while minimizing the deficiencies of
    each. See 
    id. col.2 l.32–36.
    For instance, image intensifiers are not useful in total
    darkness because they require “at least some photons to be perceived by the night vision
    device.” 
    Id. col.1 l.41–43.
    Contrastingly, thermal imagers can function in total darkness,
    
    id. col.2 l.15–18,
    because they operate by detecting the thermal signatures of warm items,
    
    id. col.2 l.5–8.
    “[H]owever, in some circumstances[,] [thermal imagers] do not provide a
    sufficiently clear image and/or may be blocked by other objects which can mask or
    interfere with . . . the perception of emitted infrared radiation.” 
    Id. col.2 l.18–22.
    The ’652 patent contains seven claims, the first of which provides:
    1.     A low light imaging device comprising:
    a)     an optical input structured to define a line of sight;
    b)     a thermal imaging assembly responsive to radiation signatures
    disposed within said line of sight;
    c)     an image intensification assembly responsive to photons at least
    within said line of sight;
    d)     said thermal imaging assembly structured to generate a real time
    thermal image representative of said radiation signatures;
    e)     said image intensification assembly structured to generate a real time
    enhanced photon based image;
    f)     an image adjustment assembly including a thermal image adjustment
    assembly and a photon image adjustment assembly;
    g)     said thermal image adjustment assembly structured to adjust an
    intensity of said thermal image;
    amplifies near-infrared light and that the other relevant type of imaging assembly—a
    thermal imager—senses “actual infrared light . . . heat energy” or “far-infrared” energy,
    such as the heat emitted by a human body).
    6
    The ’652 patent refers to adjusting image intensity, which the court understands
    to be a reference to image brightness. See, e.g., Def.’s Mot. Ex. A (’652 patent) col.6
    l.48–53; cf. infra Part III.A.2.b (finding unpersuasive plaintiff’s attempt to distinguish
    intensity from brightness).
    4
    h)     said photon image adjustment assembly structured to adjust said
    image intensification assembly so as to adjust an intensity of said
    enhanced photon based image generated thereby;
    i)     said thermal image adjustment assembly and said photon image
    adjustment assembly being structured to be operable independent
    from one another; and
    j)     an output image generation assembly structured to combine said
    thermal image and said enhanced photon based image to generate a
    real-time, direct view output image.
    
    Id. col.6 l.33–60.
    Claims four, five and seven describe the independent brightness adjustment
    feature. Claim four, which depends from claim one, provides: “A low light imaging
    device as recited in claim 1 wherein said thermal image adjustment assembly and said
    photon image adjustment assembly are structured to be independently and separately
    adjusted relative to one another.”7 
    Id. col.7 l.19–23.
    Claim five describes image
    adjustment assemblies “operable to adjust . . . [the] imaging assemblies so as to adjust an
    intensity of said thermal image and said enhanced photon based image.” 
    Id. col.7 l.33–
    38. Claim seven, although it appears to be missing several words, also seems to describe
    independent adjustment. See 
    id. col.8 l.29–33.
    B.     The Hansen Patent
    The Hansen patent lists Charles L. Hansen—an employee of the United States
    Army stationed at Fort Belvoir, Virginia—as its inventor and “[t]he United States . . .
    [whose interest is] represented by the Secretary of the Army,” as the assignee. See 
    id. Ex. B
    (Hansen patent) [73], [75]. The Hansen patent is directed toward a “multispectral
    sight.” See 
    id. [57]. According
    to its specification, the Hansen device has “processing
    means for each of . . . three distinct spectrum channels,” which “are preferably a visible
    spectrum for daytime viewing, a near infrared spectrum for twilight viewing, and a far
    infrared spectrum for thermal viewing at nighttime.” 
    Id. col.1 l.61–66.
    The Hansen
    device uses fully reflective mirrors and partially reflective mirrors (called beam
    splitters)—arranged as shown in the following schematic drawing, labeled figure 4—to
    separate, direct, and ultimately recombine the three types of radiant energy (visible light,
    near-infrared energy and far-infrared energy) into a final output image:
    7
    The elements and claims of a patent are often numbered in bold. See, e.g., Def.’s
    Mot. Ex. B (Hansen patent) col.3 l.15–39. The court omits such emphasis in this
    Opinion.
    5
    
    Id. fig. 4;
    see also 
    id. col.3 l.10–13
    (describing figure 4).
    The following description accompanies figure 4:
    The multispectral radiant energy 6 . . . enters the sight through sighting
    window 15 . . . . A first partially reflective beam splitter 16A . . . passes the
    [far-infrared] wavelengths of radiant energy . . . along a far infrared
    spectrum channel 19A for processing. Beam splitter 16A reflects the
    shorter wavelength visible and near infrared spectrums to a second partially
    reflective beam splitter 16B[,] which passes the near infrared spectrum . . .
    radiant energy . . . [,] which is reflected off a first fully reflective mirror
    16C along a near infrared spectrum channel 19C for processing. Beam
    splitter 16B reflects the visible spectrum of . . . radiant energy . . . along a
    visible spectrum channel 19B for processing. . . . All three channels have
    separate processing means and means for activating to process their
    respective radiant energy spectrums and whose processed signals exit
    therefrom . . . for an observer to view through eyepiece lens 12A.
    
    Id. col.3 l.14–39.
    Both of the imaging assemblies relevant to defendant’s Motion are portrayed in
    Figure 4. The Hansen device’s thermal imager “is comprised of the readily available
    U.S. Army forward looking infrared sight electro-optic elements”—including “an
    uncooled focal plane array 18[,] controlled by focal plane array electronics 24[,] in which
    the far infrared spectrum is converted to equivalent electrical signals[,] which are in turn
    fed directly to a cathode ray tube display 26 for reconverting the electrical signals to the
    visible spectrum.” 
    Id. col.3 l.43–53.
    The output of the cathode ray tube, which is red, “is
    6
    reflected off a fourth partially reflective beam splitter 56, which is red reflective, . . . to an
    observer.” See 
    id. col.3 l.53–57.
    The image intensifier “is preferably a U.S. Army third
    generation image intensifier tube 28[,] which amplifies and magnifies the near infrared
    image.” 
    Id. col.4 l.13–15.
    The output of the image intensifier, which is green, is
    reflected “onto beam splitter 54, which is green reflective . . . for viewing by an
    observer.” See 
    id. col.4 l.15–20.
    “The visible spectrum channel 19B operates as a
    daytime sight” and directs visible light to an observer. See 
    id. col.3 l.62–65.
    Of particular relevance to whether the Hansen device provides for independent
    brightness adjustment are the control knobs and switches on the device. These control
    knobs and switches activate the near-infrared, far-infrared and visible light channels, and
    adjust the image viewed by the user. The controls are visible in the following diagram:
    
    Id. fig. 2A.
    By turning rotary switch 30 on the Hansen device, the observer can activate the
    near-infrared channel, the far-infrared channel, the visible light channel or both the near-
    infrared and far-infrared channels. See 
    id. col.2 l.38–44.
    When the visible light channel
    is not activated, visible light is blocked by light valve 50 (visible in figure 4). See 
    id. col.3 l.65–col.4
    l.7.
    The sight’s output can be adjusted in several ways. Directly relevant to the
    parties’ arguments are the adjustment capabilities described in the Hansen patent:
    “Switches 34 and 36 control the power to [image intensifier tube] 28, [uncooled focal
    plane array] 18, [focal plane array electronics] 24, and [cathode ray tube] 26 to
    respectively control the scene contrast and brightness.” 
    Id. col.4–l.26–28; see
    also 
    id. 7 col.2
    l.44–48 (“A plurality of thumb nail rotary switches 36, 34, and 32 . . . respectively
    adjust scene brightness, contrast, and the brightness of the reticle.”8).
    C.     Procedural History
    Plaintiff filed this action on August 11, 2010, “seeking recovery of CANVS’
    reasonable and entire compensation, as well as all other appropriate remedies[] arising
    from Defendant’s [alleged] infringement of [the ’652 patent] and Defendant’s [alleged]
    use and/or manufacture, without license or lawful right, of inventions described in and
    covered by CANVS’ ’652 patent.” Compl. 1. Specifically, plaintiff alleged that the
    Enhanced Night Vision Goggle (device one) manufactured by ITT Industries infringed all
    seven claims of the ’652 patent and “has been and is being used by and has been and is
    being manufactured for the United States without license.” 
    Id. ¶¶ 17–18.
    In subsequent
    briefing, plaintiff identified nine additional accused devices, produced by several
    manufacturers, including the Dual Band Universal Night Sight (device two). See
    CANVS Corp. v. United States, 
    110 Fed. Cl. 19
    , 25 n.3 (2013) (listing the ten accused
    devices). After a series of delays and subsequent failures to comply with the court’s rules
    and orders, plaintiff’s claims with respect to accused devices three through ten have been
    dismissed for failure to prosecute. See generally CANVS Corp. v. United States, 
    107 Fed. Cl. 100
    (2012) (dismissing plaintiff’s claims with respect to devices three through
    ten); CANVS Corp., 
    110 Fed. Cl. 19
    (denying reconsideration). As a result, plaintiff is
    currently proceeding only with its claims respecting devices one and two. See CANVS
    
    Corp., 110 Fed. Cl. at 25
    .
    On November 16, 2012, plaintiff filed a motion to amend its claim chart to add six
    additional devices. See Pl. CANVS Corp.’s 2d Mot. to Show Good Cause Supporting the
    Amendment of its Infringement Claim Charts, Dkt. No. 51, at 1. The court stayed this
    motion to amend pending the court’s resolution of defendant’s instant Motion. See Order
    of Mar. 26, 2013, Dkt. No. 63, at 2.
    Defendant filed its Motion on March 12, 2013. See generally Def.’s Mot.
    Ordinarily, courts conduct claim construction proceedings before addressing whether the
    patent-in-suit is invalid. See, e.g., Akami Techs., Inc. v. Cable & Wireless Internet
    Servs., Inc., 
    344 F.3d 1186
    , 1192 (Fed. Cir. 2003) (“The first step in any invalidity
    analysis is claim construction . . . .”). In this case, however, the parties agree that claim
    construction is not required before the court decides defendant’s Motion. See Def.’s Mot.
    2 (adopting plaintiff’s position on claim construction—that, with the exception of one
    claim term, no claim construction is necessary—for purposes of defendant’s Motion).
    II.    Legal Standards
    8
    A reticle is “[a] grid or pattern placed in the eyepiece of an optical instrument,
    used to establish scale or position.” The American Heritage Dictionary of the English
    Language 1488 (4th ed. 2006).

    A.     Motions for Summary Judgment
    Pursuant to Rule 56 of the Rules of the United States Court of Federal Claims
    (RCFC), a motion for summary judgment may be granted only when “there is no genuine
    dispute as to any material fact and the movant is entitled to judgment as a matter of law.”
    RCFC 56(a).9 A fact is material if it might affect the outcome of the suit. Anderson v.
    Liberty Lobby, Inc., 
    477 U.S. 242
    , 248 (1986). A dispute about a material fact is genuine
    if, “view[ing] the record evidence through the prism of the evidentiary standard of proof
    that would pertain at a trial on the merits,” Eli Lilly & Co. v. Barr Labs., Inc., 
    251 F.3d 955
    , 962 (Fed. Cir. 2001), “the evidence is such that a reasonable [factfinder] could
    return a verdict for the nonmoving party,” 
    Anderson, 477 U.S. at 248
    .
    The moving party has the initial burden of establishing “the absence of any
    genuine issue of material fact and entitlement to judgment as a matter of law.” Crater
    Corp. v. Lucent Techs., Inc., 
    255 F.3d 1361
    , 1366 (Fed. Cir. 2001). Thereafter, “[t]he
    party opposing the motion must point to an evidentiary conflict created on the record;
    mere denials or conclusory statements are insufficient.” SRI Int’l v. Matsushita Electric
    Corp. of Am., 
    775 F.2d 1107
    , 1116 (Fed. Cir. 1985) (en banc). “The evidence of the
    non-movant is to be believed, and all justifiable inferences are to be drawn in his favor.”
    
    Anderson, 477 U.S. at 255
    . Accordingly, the court may not weigh evidence or make
    credibility determinations when ruling on a motion for summary judgment. 
    Id. B. Anticipation
    Patents are presumed to be valid, 35 U.S.C. § 282(a), a presumption that can be
    overcome only by clear and convincing evidence, Invitrogen Corp. v. Biocrest Mfg., L.P.,
    
    424 F.3d 1374
    , 1378 (Fed. Cir. 2005). Pursuant to 35 U.S.C. § 102, a patent is invalid if
    it is anticipated by the prior art, that is, if “the invention was described in . . . a patent
    granted on an application for patent by another filed in the United States before the
    invention by the applicant for patent.” 35 U.S.C. § 102(e). Specifically, “a claim is
    anticipated if each and every limitation is found either expressly or inherently in a single
    prior art reference.” Celeritas Techs., Ltd. v. Rockwell Int’l Corp., 
    150 F.3d 1354
    , 1361
    (Fed. Cir. 1998). The anticipating reference must be enabling, meaning that it “must
    teach one of ordinary skill in the art to make or carry out the claimed invention without
    undue experimentation.” Minn. Mining & Mfg. Co v. Chemque, Inc., 
    303 F.3d 1294
    ,

    III.   Discussion
    A.     Anticipation
    Defendant contends that the ’652 patent is invalid because each of its claims is
    anticipated by the Hansen device. Def.’s Mot. 1. Defendant provides a meticulously
    thorough analysis of where it believes each limitation of the claims enumerated in the
    ’652 patent can be found in the Hansen patent. See generally 
    id. Having reviewed
    defendant’s analysis and the record evidence in detail, the court finds that defendant has
    satisfied its burden of initially establishing “the absence of any genuine issue of material
    fact and entitlement to judgment as a matter of law.” Cf. Crater 
    Corp., 255 F.3d at 1366
    (stating that a party moving for summary judgment must establish “the absence of any
    genuine issue of material fact and entitlement to judgment as a matter of law”).
    To avoid summary judgment, plaintiff in turn “must point to an evidentiary
    conflict created on the record . . . .” Cf. SRI 
    Int’l, 775 F.2d at 1116
    . Plaintiff has
    identified two potential evidentiary conflicts. Plaintiff contends that defendant has
    improperly grouped claims five, six and seven together with claim one for analysis. Pl.’s
    Resp. 28–29. And plaintiff argues that the Hansen device does not anticipate the ’652

    In the context of patent law, “[e]xtrinsic evidence consists of all evidence
    external to the patent and prosecution history, including expert and inventor testimony,

    52 F.3d 967

    (1996).
    10
    patent because it “does not teach the independent adjustment of the [thermal imager] and
    [the image intensifier].” 
    Id. at 9.
    Plaintiff identifies no other potential evidentiary conflict and posits no other
    reason that defendant is not entitled to summary judgment of anticipation. For this
    reason, the court finds, as an apparent concession by plaintiff, that any claims of the ’652
    patent that do not describe independent brightness adjustment and that have not been
    improperly grouped with other claims are anticipated by the Hansen patent. The court
    therefore focuses the following discussion on the grouping of claims and independent
    brightness adjustment.
    1.     Defendant’s Grouping of Claims Is Appropriate
    Plaintiff contends that defendant has improperly grouped claims five, six and
    seven together with claim one in its discussion of anticipation instead of addressing each
    claim with separate evidence and argument. 
    Id. at 28–29;
    cf., e.g., Def.’s Mot. 13 (stating
    that, “[d]ue to the similarity of the claim language, the same reasoning [that applies to the
    thermal imager in claim one] applies to the ‘first imaging assembly’ in part (b) of claim 5
    and the ‘thermal imaging assembly’ in part (b) of claims 6 and 7”). Plaintiff contends
    that defendant has “a statutory obligation . . . to address the invalidity of each claim
    separately.” Pl.’s Resp. 29 (citation omitted). Plaintiff cites to Dayco Products, Inc. v.
    Total Containment, Inc. (Dayco), 
    329 F.3d 1358
    , 1370 (Fed. Cir. 2003), for the
    proposition that defendant’s failure to discuss the claims of the ’652 patent individually
    “is contrary to law, which requires that ‘[e]ach claim of a patent (whether in independent,
    dependent, or multiple dependent form) shall be presumed valid independently of the
    validity of other claims; [and] dependent or multiple dependent claims shall be presumed
    valid even though dependent upon an invalid claim.’” 
    Id. at 1370
    (alterations in original)
    (quoting 35 U.S.C. § 282 (2000)).
    However, as defendant correctly notes, see Def.’s Reply 22, the Dayco decision
    upon which plaintiff relies states that “it is permissible to group claims together for
    disposition where resolution involves the same issues of validity; however, the
    justification for such grouping is possible only where those issues are substantially
    materially identical,” 
    Dayco, 329 F.3d at 1370
    . In this case, defendant has explained why
    it believes that its anticipation analysis of claim one also applies to claims five, six and
    seven. See, e.g., Def.’s Mot. 13 (stating that, “[d]ue to the similarity of the claim
    language, the same reasoning [that applies to the thermal imager in claim one] applies to
    the ‘first imaging assembly’ in part (b) of claim 5 and the ‘thermal imaging assembly’ in
    part (b) of claims 6 and 7”). And claim one does appear to be “substantially materially
    identical” to claims five, six and seven for purposes of invalidity analysis. Cf. 
    Dayco, 329 F.3d at 1370
    . As one example out of many, claim one describes an “image
    intensification assembly structured to generate a real time enhanced photon based
    image.” Def.’s Mot. Ex. A (’652 patent) col.6 l.42–43. Claims five, six and seven
    describe a nearly identical assembly. See 
    id. col.7 l.30–32
    (claim five, describing an
    11
    “imaging assembly structured to generate an enhanced photon based image”); 
    id. col.8 l.9–11
    (claim six, describing “an image intensification assembly structured to generate an
    enhanced photon based image”); 
    id. col.8 l.26–28
    (claim seven, describing “an image
    intensification assembly structured to generate an enhanced photon based image”).
    Plaintiff fails to rebut this showing with its own explanation of why claims five,
    six and seven are materially different for purposes of anticipation. On the contrary,
    plaintiff concedes that, for purposes of defendant’s Motion, claim one is representative of
    claims five, six and seven. See Pl.’s Resp. 6 n.2 (stating that the differences between the
    claims, “except for claim 4, are not material to the issues of validity raised by
    Defendant”). The court therefore concludes that defendant’s discussion of claim one
    simultaneously with claims five, six and seven is appropriate. Cf. 
    Dayco, 329 F.3d at 1370
    (stating that grouping is permissible where the issues raised by each claim “are
    substantially materially identical”).
    2.     A Reasonable Factfinder Could Conclude that Independent Brightness
    Adjustment Is Not Found—Either Expressly or Inherently—in the Hansen
    Patent
    a.     A Reasonable Factfinder Could Conclude that Independent Brightness
    Adjustment Is Not Expressly Described in the Hansen Patent
    Plaintiff contends that the Hansen patent does not anticipate the ’652 patent
    because it “does not teach the independent adjustment of the [thermal imager] and [the
    image intensifier].” Pl.’s Resp. 9; see also Oral Argument of Mr. Zito at 10:05:45–06:03
    (contending that whether the Hansen patent anticipates this feature of the ’652 patent is
    “[t]he essence of what we’re talking about today”). This independent brightness
    adjustment feature is described in claims four, five and seven of the ’652 patent.11 Def.’s
    11
    Plaintiff maintains that this individual adjustment is described in parts (i) and (j)
    of claim one of the ’652 patent. See Oral Argument of Mr. Zito at 10:17:10–24, 44–53;
    cf. Pl.’s Resp. 8–9 (asserting that parts (f) through (j) together make it possible “to
    independently adjust the intensity of both of the image sensors to deliver the proper mix
    of image intensity”). The court understands plaintiff to be referring specifically to part (i)
    of claim one, which describes the image intensifier and the thermal imager as “being
    structured to be operable independent from one another.” Def.’s Mot. Ex. A (’652
    patent) col.6 l.54-56. However, this is a description, not of independent adjustability, but
    of independent operability, a feature the Hansen patent plainly teaches. The Hansen
    patent states that rotary switch 30 may be turned to connect to one of four electrical
    contacts: “electrical contact 31A for activating the visible spectrum of the multispectral
    sight, contact 31B for activating the near infrared spectrum, contact 31C for activating
    the far infrared spectrum, or contact 31D for activating both the near infrared spectrum
    and the far infrared spectrum simultaneously.” Def.’s Mot. Ex. B (Hansen patent) col.2
    l.38–44.
    12
    Mot. Ex. A (’652 patent) col.7 l.19–23 (claim four), col.7 l.33–38 (claim five), col.8 l.29–
    33 (claim seven).
    The court first considers whether the Hansen patent expressly teaches independent
    brightness adjustment. Both parties focus on the following sentence of the Hansen patent
    specification: “Switches 34 and 36 control the power to [image intensifier tube] 28,
    [uncooled focal plane array] 18, [focal plane array electronics] 24, and [cathode ray tube]
    26 to respectively control the scene contrast and brightness.” Def.’s Mot. Ex. B (Hansen
    patent) col.4 l.26–28; cf. Def.’s Mot. 15–16 (interpreting this sentence); Pl.’s Resp. 9–15
    (same); Def.’s Reply 14–15 (same). No wiring diagram was included to show the
    connections described in this sentence.
    Plaintiff contends that the “[p]lain reading of the sentence demonstrates that
    [switches 34 and 36 control] the brightness and contrast of the entire scene,” but not of
    the thermal imager and image intensifier individually. Pl.’s Resp. 11 (emphasis omitted).
    Plaintiff contends that the sentence “could be re-written as: Switch 34 controls the power
    to 28, 18, 24, and 26 to control the scene contrast [and] switch 36 controls the power to
    28, 18, 24, and 26 to control scene brightness.” 
    Id. (italicization omitted);
    see also 
    id. at 10
    (“[B]oth switches are connected to both sensors . . . .”); Oral Argument of Mr. Zito at
    10:23:54–24:01 (“Switch 34 respectively controls contrast. Switch 36 respectively
    controls brightness.”).
    Defendant responds that “the most logical reading” of the sentence is that “rotary
    switch 34 controls power to the image intensifier 28, while rotary switch 36 controls
    power to the thermal imager, which comprises elements 18, 24, and 26.” Def.’s Reply
    14. Stressing the Hansen patent’s use of the word “‘respectively’” and the fact that the
    Hansen patent describes “‘separate processing means’” for the image intensifier and the
    thermal imager, defendant contends that it would be logical to group element 28 (the
    image intensifier) apart from elements 18, 24 and 26 (the thermal imager) and to assign a
    separate power control to each. See id. (quoting 
    id. Ex. B
    (Hansen patent) col.3 l.34–35);
    Oral Argument of Mr. Hudalla at 11:08:44–47 (“[O]f course, you would group the
    elements of the thermal imager together.”). Therefore, defendant contends, “thumb nail
    rotary switches 34 and 36 in Hansen control the power to the image intensifier and the
    thermal imager, respectively.” Def.’s Mot. 15.
    It is the court’s view, however, that the plain meaning of the contested sentence
    favors plaintiff’s position. The word “respectively” means “[s]ingly in the order
    designated or mentioned.” The American Heritage Dictionary of the English Language
    1485 (4th ed. 2006). Therefore, if “[s]witches 34 and 36 . . . respectively control the
    scene contrast and brightness,” Def.’s Mot. Ex. B (Hansen patent) col.4 l.26–28, it would
    follow that switch 34 controls scene contrast and switch 36 controls brightness.
    Additional support for this interpretation of the patent language at issue is found in
    the following sentence that appears on the previous page of the Hansen patent: “A
    13
    plurality of thumb nail rotary switches 36, 34, and 32, . . . respectively adjust scene
    brightness, contrast, and the brightness of the reticle.” 
    Id. col.2 l.44–48.
    This earlier
    appearing sentence uses a construction similar to that in the later contested sentence,
    without mention of the two imaging assemblies to which—defendant asserts—the word
    “respectively” refers. The earlier appearing sentence with similar construction would
    seem to unambiguously state that switch 36 controls scene brightness, switch 34 controls
    scene contrast and switch 32 controls the brightness of the reticle. For this reason, the
    court is persuaded that a reasonable factfinder could conclude that defendant has failed to
    prove by clear and convincing evidence that the Hansen patent expressly discloses
    independent brightness adjustment. Cf. Eli Lilly & 
    Co., 251 F.3d at 962
    (stating that “a
    moving party seeking to invalidate a patent at summary judgment must submit such clear
    and convincing evidence of invalidity so that no reasonable [factfinder] could find
    otherwise”). Having determined that a reasonable factfinder could conclude that
    independent brightness adjustment is not explicitly present in the Hansen patent, the court
    considers whether such adjustment feature could be found to be inherently present.
    b.     A Reasonable Factfinder Could Conclude that Independent Brightness
    Adjustment Is Not Inherently Present in the Hansen Patent
    When extrinsic evidence has been presented to establish that a feature is inherently
    present, “[t]he evidence must make clear that the missing feature is necessarily present,
    and that it would be so recognized by persons of ordinary skill in the relevant art.”
    Telemac Cellular 
    Corp., 247 F.3d at 1328
    .
    As the preceding discussion indicates, the Hansen patent states that switch 34
    controls the power to the image intensifier and thermal imager to control scene contrast,
    and switch 36 controls the power to the image intensifier and thermal imager to control
    scene brightness. See Def.’s Mot. Ex. B (Hansen patent) col.2 l.44–48, col.4 l.26–28.
    Defendant contends that the term “scene contrast” would not be understood to refer, as
    plaintiff asserts, to “the relative difference between the lightest and darkest portions” of
    the images created by the image intensifier and the thermal imager, see Pl.’s Resp. 15
    (citing 
    id. Ex. C.
    (Gillespie Aff.) ¶ 5012), but rather to the color contrast between the
    green image created by the image intensifier and the red image created by the thermal
    imager, Def.’s Reply 17; see also Oral Argument of Mr. Hudalla at 11:12:07–10 (“The
    scene contrast here is color contrast.”). The user would adjust this type of color contrast
    by adjusting the relative brightness of the red and green images to create more or less of
    the final image. See Oral Argument of Mr. Hudalla 11:13:32–38 (“The contrast comes
    from color contrast. You can turn the red up; you can turn the green up.”). As defendant
    12
    The affidavit of Mr. Gillespie, plaintiff’s expert witness, is organized into
    numbered paragraphs but also contains section titles that are not numbered. See Pl.’s
    Resp. Ex. C (Gillespie Aff.) passim. The court provides paragraph numbers when citing
    the numbered paragraphs and page numbers when citing the section titles.
    14
    correctly notes, see Def.’s Reply 17, plaintiff agrees that “scene contrast” could refer to
    color contrast, see Pl.’s Resp. 16 (stating that “‘scene contrast’ could include ‘color
    contrast’ under certain circumstances”); cf. Pl.’s Resp. Ex. C (Gillespie Aff.) ¶ 52 (same).
    Defendant insists that the term “scene contrast” would be understood to refer to
    this type of color contrast resulting from relative brightness because plaintiff’s
    interpretation of the Hansen patent would require switch 34 “to do the impossible—
    namely, to control the contrast of an image intensifier.” Def.’s Reply 15. Defendant
    accurately observes, and plaintiff’s expert witness agrees, that the contrast of an image
    intensifier cannot be adjusted. 
    Id. (citing, inter
    alia, 
    id. Ex. J
    (Gillespie Dep.) 30:19–
    31:18 (“[Was there a way to] adjust the contrast of the output of an image intensifier . . . ?
    No, not that I know of.”)). On the other hand, the record evidence establishes that a
    person of ordinary skill in the art would have known that it is possible to adjust the
    brightness of both an image intensifier and a thermal imager by controlling the power to
    them. See 
    id. Ex. K
    (2d Waxman Aff.) ¶¶ 4–8 (presenting evidence that power control to
    adjust the brightness of image intensifiers and thermal imagers was known in the art); cf.
    Pl.’s Resp. 19 (“[C]ertain advanced [image intensification] tubes had and have the ability
    to manually adjust the gain or power delivered to the tube to vary the intensity of the
    image that is output to the user.”)13; Pl.’s Resp. Ex. C (Gillespie Aff.) ¶ 57 (same).
    Defendant adds that plaintiff’s view of the Hansen patent requires both switch 34 and
    switch 36 to control the power to both imaging assemblies, a redundancy that defendant
    argues “would be equivalent to having two volume controls on your radio in your car.”
    Oral Argument of Mr. Hudalla at 11:17:35–54.
    In response, plaintiff quotes testimony from its fact witness, Mr. Dumais—whom
    plaintiff describes as “the Navy WARCOM and SOCOM Joint Night Vision Working
    Group leader in charge of night vision at the critical time period”—stating that the Army
    did not “actually invent[] the subject matter” of the ’652 patent. Pl.’s Resp. 4. Mr.
    Dumais further testified that the CANVS device “gave us capability to do things that I
    13
    At oral argument and in its Sur-Reply, plaintiff contradicted its earlier
    expounded position by arguing that it is not possible to control the brightness of an image
    intensifier by controlling its power supply. See Oral Argument of Mr. Zito at 10:31:02–
    17 (“You cannot control the brightness of . . . an image intensifier by controlling the
    external power to the image intensifier.”); Pl.’s Sur-Reply, Dkt. No. 78, at 2–3 (disputing
    whether the references cited by defendant establish that it is possible to control brightness
    by controlling power); cf. Pl.’s Sur-Reply Ex. G (2d Gillespie Aff.) ¶¶ 17–19 (same).
    This argument is untimely—being raised for the first time in a sur-reply. It also
    contradicts the previous position advanced by both plaintiff and its expert witness. The
    court therefore deems it to be waived. Cf. Becton Dickinson & Co. v. C.R. Bard, Inc.,
    
    922 F.2d 792
    , 800 (Fed. Cir. 1990) (discussing “the sound practice that an issue not
    raised by an appellant in its opening brief . . . is waived” unless waiver “would result in
    basically unfair procedure”).
    15
    knew we were not capable [of] before.’” 
    Id. at 1;
    id. Ex. D 
    (Dumais Dep.) 140:9–11.
    The implication of this testimony is that if the Hansen device—which was invented by an
    Army employee, see Def.’s Mot. Ex. B (Hansen patent) [75] (stating that Mr. Hansen was
    stationed at Fort Belvoir, Virginia)—had featured independent brightness adjustment, Mr.
    Dumais would have been aware of it. However, as defendant rightly points out, “Mr.
    Dumais was on active duty with the Navy at the time of [the] Hansen [device’s
    patenting], so it is unsurprising that Mr. Dumais was not aware of all—or even any—of
    the night vision development activities occurring within the Army.” Def.’s Reply 4
    (citing Pl.’s Resp. Ex. D (Dumais Dep.) 21:22–22:2).
    Plaintiff then makes a number of arguments—based on the testimony of its expert
    witness, Mr. Gillespie—about how the Hansen patent would be interpreted by a person of
    ordinary skill in the art. Certain of the arguments plaintiff puts forward are not supported
    by the record evidence. Others contradict plaintiff’s prior positions—without
    explanation—or focus on issues that are irrelevant to an anticipation analysis on summary
    judgment. The court has closely studied these arguments but concludes that they would
    fail to persuade a reasonable factfinder that an independent adjustment feature is
    inherently present in the Hansen patent. The court sets forth a few illustrative examples
    of plaintiff’s arguments below.
    Plaintiff first contends that the Hansen patent could not have referred to red-green
    color contrast because, “at the time the Hansen invention was made, night vision goggles
    did not have color displays” and instead “provided a monochrome image to the user.”
    Pl.’s Resp. 16 (citing, inter alia, 
    id. Ex. C
    (Gillespie Aff.) ¶ 52). But, the court
    understands this argument to reflect a misstatement by Mr. Gillespie in his affidavit,
    which was subsequently addressed in his deposition. See Def.’s Reply Ex. J (Gillespie
    Dep.) 177:3–179:15 (acknowledging that he had “used the wrong terminology” in the
    referenced paragraph of his affidavit, that night vision devices had “colored display but
    not color display” and that the Hansen device would have combined a red and a green
    image).
    Plaintiff also asserted in its briefing that defendant’s expert witness, Dr. Waxman,
    incorrectly interpreted the transmissive properties of the beam splitters described in the
    Hansen patent. Pl.’s Resp. 17–18; see also Pl.’s Sur-Reply 1–2, 4–7. At oral argument,
    plaintiff explained that it had offered this argument, “not because [it] somehow makes
    [the Hansen patent] a nonanticipatory reference,” but to rehabilitate the credibility of its
    witnesses, Mr. Gillespie and Mr. Dumais. See Oral Argument of Mr. Zito at 11:50:03–
    51:39. The court declines plaintiff’s invitation to consider this argument because
    credibility determinations cannot be made in the context of a summary judgment motion.
    
    Anderson, 477 U.S. at 255
    .
    Plaintiff further argued in briefing that the Hansen patent did not anticipate the
    ’652 patent because “the Hansen patent [w]as just another example of overlay technology
    or ‘poor man’s fusion.’” Pl.’s Resp. 4 (quoting 
    id. Ex. D
    (Dumais Dep.) 58:19); see also
    
    id. at 5–6
    (stating that “the CANVS device was the first time that true optical fusion had
    been accomplished”). As clarified during oral argument, plaintiff’s argument appears to
    16
    turn on its view of a qualitative distinction between the fusion achieved in the Hansen
    device and that accomplished by the ’652 patent. See, e.g., Oral Argument of Mr. Zito at
    10:46:57–47:12 (“Overlay is fusion; fusion is overlay. If you just do overlay, it’s poor
    man’s fusion. If you improve the overlay . . . , then it becomes good fusion or true
    fusion . . . .”). However, plaintiff identifies no record evidence that described precisely
    what this distinction is or why it is significant in this anticipation analysis.
    Although plaintiff agreed in its briefing that the terms “brightness,” as used in the
    Hansen patent, and “intensity,” as used in the ’652 patent, are synonymous, see, e.g., Pl.’s
    Resp. 15 (stating that “a person of ordinary skill in the art would understand . . . [the
    term] ‘light intensity’” used in the Hansen patent to mean “‘scene brightness’”), plaintiff
    contradicted its earlier offered view at oral argument. There, plaintiff appeared to
    contend that the Hansen patent’s adjustment of brightness does not anticipate the ’652
    patent’s adjustment of intensity. Instead, plaintiff posited that “brightness . . . refers to
    one way of changing the intensity,” whereas intensity refers to the “quant[um] of
    information” transmitted to the viewer. Oral Argument of Mr. Zito at 10:43:10–29.
    When asked whether supportive evidence for this proposition could be found in the
    record, plaintiff responded, “No, other than how the term is used in [the ’652] patent.”
    
    Id. at 10:47:18–48:10.
    In accordance with the Federal Circuit’s guidance, however, the
    Hansen patent need not use precisely the same phrasing as the ’652 patent to anticipate its
    claims. Cf. In re Bond, 
    910 F.2d 831
    , 832 (Fed. Cir. 1990) (stating that anticipation “is
    not an ‘ipsissimis verbis’ test”).
    Among the many alternative arguments it put forward, plaintiff contends, “[T]here
    is no evidence of the Hansen invention. No prototypes, no records, no proposals,
    nothing.” Pl.’s Resp. 4. But as defendant correctly observes, “‘[a]nticipation does not
    require the actual creation or reduction to practice of the prior art subject matter;
    anticipation requires only an enabling disclosure.’” Def.’s Reply 21 (alteration in
    original) (quoting Schering Corp. v. Geneva Pharms., Inc., 
    339 F.3d 1373
    , 1380 (Fed.
    Cir. 2003)).
    Plaintiff suggests that the Hansen patent was insufficiently detailed to be such an
    enabling disclosure, see Pl.’s Resp. 14 (stating that the Hansen patent provides “no idea,
    explanation or suggestion to how to achieve” adjustment of scene brightness or scene
    contrast), but the Hansen patent is no less detailed than the ’652 patent. Missing from the
    ’652 patent is a description of how image brightness is to be adjusted, and as defendant
    accurately states in its briefing, the same presumption of enablement that applies to the
    ’652 patent applies to prior art references. Def.’s Reply 21 (citing Amgen Inc. v. Hoechst
    Marion Roussel, Inc., 
    314 F.3d 1313
    , 1315 (Fed. Cir. 2009)).
    A feature asserted to be inherent in a prior art reference must be shown to be
    “necessarily present, not merely probably or possibly present.” Trintec Indus., Inc. v.
    Top-U.S.A. Corp., 
    295 F.3d 1292
    , 1295 (Fed. Cir. 2002) (internal quotation marks
    omitted). Here, defendant’s burden is to demonstrate that independent brightness
    adjustment is necessarily present in Hansen with “such clear and convincing evidence of
    17
    invalidity . . . that no reasonable [factfinder] could find otherwise.” Cf. Eli Lilly & 
    Co., 251 F.3d at 962
    . The court is not persuaded on this record that defendant has met this
    burden.
    Defendant effectively alleges that a person of ordinary skill in the art would know
    that this control configuration does not operate as described because controlling contrast
    through an image intensifier is not possible and because using two switches to control the
    power for both imaging devices is unnecessarily redundant. Defendant posits that one
    switch should be understood to control the brightness of each imaging assembly, which
    allows the color contrast of the scene to be adjusted. But the record evidence before the
    court does not compel a reasonable factfinder to reach this conclusion. In addition,
    although defendant’s interpretation of the language of the Hansen patent might offer a
    more functional device, it does not comport with the patent’s seemingly plain language
    that one switch controls contrast and the other controls brightness. Accordingly, a
    reasonable factfinder could conclude that defendant has failed to prove by clear and
    convincing evidence that independent brightness adjustment is necessarily present in the
    Hansen patent.14 Cf. Eli Lilly & 
    Co., 251 F.3d at 962
    .
    Absent such clear and convincing proof from defendant, a genuine issue of
    material fact remains regarding whether the claims that describe independent brightness
    adjustment (these are, claims four, five and seven) are anticipated by the Hansen patent.
    Cf. 
    id. Defendant, however,
    has succeeded in showing—and plaintiff has failed to create
    a genuine issue of material fact rebutting such showing—that the other claims
    (specifically, claims one through three and claim six) are anticipated by the Hansen
    patent. Plaintiff’s arguments with respect to grouping and independent brightness
    adjustment do not persuade, 
    see supra
    Part III.A.1 (discussing grouping), III.A.2
    (discussing independent brightness adjustment), and plaintiff provides no basis upon
    which a reasonable factfinder could conclude differently, cf. Eli Lilly & 
    Co., 251 F.3d at 962
    .
    14
    Additionally, it is not clear to the court that it properly could find that
    independent brightness adjustment is inherently present in the Hansen device on the basis
    of extrinsic evidence that contradicts the express language of the Hansen patent. Cf.
    
    Markman, 52 F.3d at 980
    (stating, in the context of claim construction, that “[e]xtrinsic
    evidence is to be used for the court’s understanding of the patent, not for the purpose of
    varying or contradicting the terms of the claims”); Rhine v. Casio, Inc., 
    183 F.3d 1342
    ,
    1345 (Fed. Cir. 1999) (stating, in the context of claim construction, that “the familiar
    axiom that [c]laims should be so construed, if possible, as to sustain their validity” has no
    application “if the only claim construction that is consistent with the claim’s language
    and the written description renders the claim invalid” (alteration in original) (internal
    quotation marks omitted)).
    18
    Accordingly, defendant is entitled to summary judgment on the issue of
    anticipation with respect to claims one through three and claim six, but not with respect
    to claims four, five and seven.
    B.     Obviousness
    Defendant argues in the alternative that claims two and three of the ’652 patent are
    rendered obvious by the combination of the Hansen patent and a second prior art
    reference. Def.’s Mot. 23–24. However, because the court has determined that claims
    two and three are invalid due to anticipation by the Hansen patent, the court does not—
    and need not—reach defendant’s obviousness argument. Cf. 3 Moy’s Walker on Patents
    § 9:49 (4th ed. 2013) (stating that, where claims are found to be anticipated, “the issue of
    obviousness need not be reached”).
    C.     The Offered Expert Testimony
    Defendant’s final argument is that the testimony of plaintiff’s expert, Mr.
    Gillespie, “is so defective as to call into question his qualification as an expert witness in
    this case.” Def.’s Reply 23. Defendant argues that “the Court should exercise its
    gatekeeping role and cast aside Mr. Gillespie’s opinions” pursuant to the Supreme
    Court’s guidance in Daubert v. Merrell Dow Pharmaceuticals, Inc., 
    509 U.S. 579
    (1993).
    
    Id. Among the
    challenges defendant directs toward Mr. Gillespie’s testimony are: (1)
    his erroneous assertion that it is not possible to adjust the brightness of an image
    intensifier; and (2) “Mr. Gillespie’s faulty analysis of rotary power control switches 34
    and 36 in [the] Hansen [device, which] not only ignore[d] the interaction of these
    switches with selector switch 30, but . . . also [was] premised on the implementation of a
    contrast control for an image intensifier that he admitted was impracticable.” 
    Id. In addition,
    defendant points to Mr. Gillespie’s concession in his deposition that he is “‘not
    a beam splitter expert.’” Id. (quoting 
    id. Ex. J
    (Gillespie Dep.) 169:4). Defendant argues
    that “because Mr. Gillespie’s faulty opinions undergird all of plaintiff’s arguments, the
    Court should find that plaintiff has failed to raise a genuine issue of material fact.”15 
    Id. at 23–24.
    15
    Plaintiff contends that “[a] ‘suggestion . . . that the Court should exercise its
    gatekeeping role’ is not a proper Daubert motion and . . . objects to the inference that Mr.
    Gillespie’s opinions could be ‘cast aside’ based upon a suggestion.” Pl.’s Sur-Reply 1
    n.1 (emphasis added). Notwithstanding plaintiff’s assertion, it is not clear to the court
    that defendant’s effort to exclude Mr. Gillespie’s testimony “is not a proper Daubert
    motion.” Cf. 
    id. (emphasis added).
    Although adduced in a reply brief, defendant’s
    request is timely because it responds and objects to the positions taken by Mr. Gillespie
    in an affidavit submitted with plaintiff’s Response. See Def.’s Reply in Supp. of its Mot.
    for Summ. J. of Invalidity of all Claims of the Patent-in-Suit, Dkt. No. 69, at 23–24.
    Plaintiff asked for—and was granted—oral argument and leave to file a sur-reply on the
    19
    Pursuant to the Federal Rules of Evidence, “the trial judge must ensure that any
    and all scientific testimony or evidence admitted is not only relevant, but reliable.”
    
    Daubert, 509 U.S. at 589
    . After reviewing carefully the asserted flaws in Mr. Gillespie’s
    offered expert testimony, the court declines to grant defendant’s request to exclude Mr.
    Gillespie’s testimony. Mr. Gillespie did title a section of his affidavit “No gain or
    intensity control of an [image intensifier] tube in 1990,” and he made averments
    consistent with that proposition. Pl.’s Resp. Ex. C (Gillespie Aff.) 19 (emphasis and
    some capitalization omitted). Moreover, when Mr. Gillespie was asked in his deposition
    to confirm that, “there is no way to change the brightness of the green screen that a user
    sees on an [image intensifier] tube,” he responded, “Correct.” Def.’s Reply Ex. J
    (Gillespie Dep. 64:18-21). But Mr. Gillespie did also acknowledge in his affidavit that
    “certain advanced [image intensifier] tubes had and have the ability to manually adjust
    the gain or power delivered to the tube to vary the intensity of the image that is output to
    the user,” Pl.’s Resp. Ex. C (Gillespie Aff.) ¶ 57. The court is persuaded that a
    reasonable factfinder could agree with Mr. Gillespie’s proposed interpretation of switches
    34 and 36, 
    see supra
    Part III.A.2, and to the extent defendant is convinced that Mr.
    Gillespie’s testimony is erroneous on the subject of independent brightness adjustment
    capacity, the court urges defendant to address such concerns by further motion or at trial.
    Contrary to defendant’s urging, the court does not exclude Mr. Gillespie’s
    testimony on the topic of beam splitters based on his concession that he is “not a beam
    splitter expert.” Cf. Def.’s Reply Ex. J (Gillespie Dep.) 169:4. Mr. Gillespie admitted
    that he “relied on . . . the optics guys to do that when we did it at the lab” and forthrightly
    stated that he was “surmising” about the operation of the beam splitters. 
    Id. at 169:4–8.
    Expertise in beam splitting appears to be a subspecialty of the optics specialists working
    with night vision technology. Having reviewed Mr. Gillespie’s testimony with respect to
    beam splitters, the court does not find Mr. Gillespie’s testimony on beam splitters to be
    so uninformed or otherwise unreliable that it must be excluded. Moreover, because the
    court is mindful of the cost to the parties associated with the hiring of multiple specialists
    in the various fields associated with night vision, see RCFC 1 (directing the court to
    pursue the “just, speedy, and inexpensive determination of every action and proceeding”),
    and because both parties appear to consider the beam splitter discussion irrelevant to
    whether the Hansen patent is an anticipatory reference, see Oral Argument of Mr. Zito at
    11:50:03–51:39 (stating that plaintiff presented evidence with respect to beam splitters,
    “not because that somehow makes [the Hansen patent] a nonanticipatory reference,” but
    to rehabilitate the credibility of plaintiff’s witnesses Mr. Gillespie and Mr. Dumais); Oral
    Argument of Mr. Hudalla at 11:28:09–29:43 (stating that plaintiff’s arguments about
    beam splitters are irrelevant to an anticipation analysis), the court denies defendant’s
    issue of expert qualification. See Order of Aug. 27, 2013, Dkt. No. 75, at 2–3. As a
    procedural matter, plaintiff therefore was afforded ample opportunity to respond to
    defendant’s challenge.
    20
    request. Should the functioning of beam splitters emerge, however, as an important issue
    in this case, defendant may renew its motion.
    Plaintiff also asserted a challenge to the admission of defendant’s expert’s
    testimony. Plaintiff argued that “if any testimony should be ‘cast aside’ based upon a
    suggestion, it should be the testimony of Dr. Waxman,” who “blatantly misquoted the
    Hansen reference.” Pl.’s Sur-Reply 1 n.1 (citing Pl.’s Resp. 12–13). It is plaintiff’s view
    that Dr. Waxman engaged in an exercise of “intentional misleading” by “refer[ing] to
    sentences he . . . made up as direct quotes . . . from [the] Hansen [patent].” Pl.’s Resp.
    12–13. Plaintiff contends that Dr. Waxman “selectively removed words” to alter the
    sentence describing switches 34 and 36 of the Hansen patent so it would appear to teach
    independent brightness adjustment of the image intensifier and the thermal imager. 
    Id. at 12;
    see 
    also supra
    Part III.A.2.a (discussing the parties’ arguments with respect to this
    sentence). But, it is apparent to the court from Dr. Waxman’s affidavit that he rephrased
    the sentence of interest—as did plaintiff’s expert16—merely to clarify what he believed it
    to mean, not to mislead the court. See Def.’s Mot. Ex. E (Waxman Aff.) ¶ 9 (explaining
    the referenced sentence). Thus, plaintiff’s argument does not persuade. The court denies
    plaintiff’s request to strike Dr. Waxman’s testimony.
    IV.    Conclusion
    As explained in much greater detail in this Opinion, defendant’s Motion is
    GRANTED with respect to the anticipation of claims one through three and claim six of
    the ’652 patent. The court finds that each limitation of these claims is found in the
    Hansen patent. Defendant’s Motion is DENIED, however, with respect to the
    anticipation of the claims of the ’652 patent that describe independent adjustment of the
    brightness of the image intensifier and thermal imager—that is, claims four, five and
    seven—because a reasonable factfinder could conclude that the Hansen patent does not
    teach this feature. Because it is unnecessary to reach the issue of obviousness,
    defendant’s Motion is DENIED with respect to the obviousness of claims two and three
    as MOOT. Defendant’s motion is also DENIED insofar as defendant requests the
    striking of Mr. Gillespie’s testimony because the court does not find Mr. Gillespie’s
    testimony so unreliable as to compel such action. In addition, the court finds
    unpersuasive plaintiff’s request to strike the testimony of Dr. Waxman as misleading and
    DENIES same.
    A separate order will issue shortly, after the issuance of this Opinion, to address
    plaintiff’s stayed motion to amend its claim chart to include additional devices.
    16
    Plaintiff similarly proposed that the same sentence could be rephrased to clarify
    its meaning. See Pl.’s Resp. 11 (suggesting that the sentence “could be re-written as:
    Switch 34 controls the power to 28, 18, 24, and 26 to control the scene contrast [and]
    switch 36 controls the power to 28, 18, 24, and 26 to control scene brightness”
    (italicization omitted)).
    21
    IT IS SO ORDERED.
