    2                         QUALITY EDGE, INC.   v. ROLLEX CORP.
    Before NEWMAN, CHEN, and STOLL, Circuit Judges.
    STOLL, Circuit Judge.
    Rollex Corporation appeals the district court’s grant of
    summary judgment of infringement of Quality Edge, Inc.’s
    U.S. Patent No. 7,137,224. Rollex also appeals the dis-
    trict court’s permanent injunction order, dismissal of its
    invalidity defenses and counterclaim, and denial of its
    discovery and evidentiary motions. Finally, Rollex seeks
    reassignment of this case to another district judge on
    remand. Because we disagree with the district court’s
    claim construction, we vacate the district court’s summary
    judgment of infringement, vacate the permanent injunc-
    tion, and remand to the district court for further proceed-
    ings. We affirm the dismissal of Rollex’s invalidity
    defenses and counterclaim, as well as the district court’s
    discovery and evidentiary rulings, and deny Rollex’s
    request for reassignment.
    BACKGROUND
    This case concerns soffit panels (“soffits”), which are
    used to enclose the eaves of homes and buildings. The
    ’224 patent provides that “[s]offit panels are generally
    well-known in the art, and serve to cover or enclose the
    underside of the eaves of homes and other buildings of the
    type having roof eaves which extend beyond and hang
    over the outside walls of the building.” ’224 patent col. 1
    ll. 9–13. The ’224 patent explains that “the soffit is nor-
    mally vented to allow outside air to flow into the attic of
    the building to equalize the attic temperature and pres-
    sure with that of the outside environment.” 
    Id. at col.
    1. ll. 16–19. These prior art soffits have certain
    drawbacks, including the presence of “exposed or visible
    vents [that] detract[] from the overall appearance of the
    structure.” 
    Id. at col.
    1 ll. 28–30.
    To solve this problem, the ’224 patent purports to pro-
    vide “a vented soffit panel . . . which includes a generally
    QUALITY EDGE, INC.   v. ROLLEX CORP.                       3
    flat imperforate base portion shaped to enclose at least a
    portion of the building soffit when mounted in a generally
    horizontal orientation under an eave.” 
    Id. at col.
    1 ll. 36–
    40. As illustrated in Figure 1 of the ’224 patent, the
    “vented soffit panel 1 includes a generally flat imperforate
    base portion 2 shaped to enclose at least a portion of the
    building soffit . . . when mounted in a generally horizontal
    orientation under an eave.” 
    Id. at col.
    2 ll. 60–63. “At
    least one vent channel 5 . . . protrudes upwardly from the
    base portion 2, and has a generally trapezoidal shape
    defined by a horizontal imperforate top wall 6, and in-
    clined perforate sidewalls 7 . . . that connect with base
    portion 2.” 
    Id. at col.
    2 l. 63 – col. 3 l. 1. “The perforate
    sidewalls 7 are disposed at an acute angle relative to top
    wall 6 and base portion 2, such that they are hidden from
    view from a position underneath eave 4.” 
    Id. at col.
    3
    ll. 2–5.
    The specification further teaches that, as shown in
    Figure 2 below, while “each of the sidewalls 7 is perforate,
    and therefore permits air to pass therethrough,” 
    id. at col.
    3 ll. 41–43, “the top wall 6 of vent channel 5 is sub-
    stantially imperforate, and therefore does not permit air
    to pass therethrough,” 
    id. at col.
    3 ll. 33–35.
    4                         QUALITY EDGE, INC.   v. ROLLEX CORP.
    The ’224 patent includes two independent claims 1
    and 42. 1 Claim 1 is reproduced below with the disputed
    claim limitation emphasized.
    1. A vented soffit panel for building roofs and
    the like of the type having at least one eave with a
    soffit thereunder; comprising:
    a generally flat, imperforate base portion
    shaped to enclose at least a portion of the soffit
    when mounted in a generally horizontal orienta-
    tion under the eave; and
    at least one vent channel portion extending
    along said base portion, and protruding upwardly
    therefrom; said vent channel portion having a
    generally trapezoidal lateral cross-sectional shape
    defined by a generally horizontal imperforate top
    wall and inclined perforate sidewalls with lower
    ends thereof connected with said base portion in a
    mutually spaced apart relationship to define a slot
    therebetween through which ambient air enters
    into said vent channel and flows through said per-
    forate sidewalls to vent the eave; said perforate
    1  Claim 1 is an apparatus claim and claim 42 is a
    method claim. Because both claims contain the same
    disputed claim limitation, we only reproduce claim 1 as
    representative.
    QUALITY EDGE, INC.   v. ROLLEX CORP.                        5
    sidewalls being disposed at a predetermined acute
    angle relative to said top wall and said base por-
    tion, whereby when said soffit panel is installed in
    said generally horizontal orientation, said perfo-
    rate sidewalls are hidden from view from a posi-
    tion underneath the eave.
    
    Id. at col.
    5 ll. 10–31 (emphasis added).
    Rollex and Quality Edge are direct competitors in the
    soffit industry. Quality Edge sued Rollex, alleging that
    Rollex’s Stealth Soffit™ infringed the ’224 patent.
    Pursuant to the district court’s local rules, Rollex filed
    a request for leave to file an early motion for summary
    judgment of noninfringement. Rollex contended it was
    entitled to judgment of noninfringement because “[n]o
    amount of argument or discovery can change the undis-
    puted facts that: (1) each of the claims of the ’224 Patent
    requires that the top wall of the vent channel have no
    holes, and (2) the top wall of the vent channel in [its]
    Stealth Soffit™ has holes.” J.A. 128.
    Quality Edge responded that the disputed claim limi-
    tation “a generally horizontal imperforate top wall” re-
    quired construction.     The district court agreed and
    adopted Quality Edge’s proposed construction, interpret-
    ing the term to mean “[d]efined by a generally horizontal
    imperforate top wall, wherein any perforations in the top
    wall are hidden from a view underneath the eaves.”
    Quality Edge, Inc. v. Rollex Corp., No. 1:10-cv-278, 
    2012 WL 1790026
    , at *7 (W.D. Mich. May 16, 2012) (“Claim
    Construction Decision”).
    Rollex filed a motion for summary judgment of inva-
    lidity, arguing that, as construed by the district court, the
    claims of the ’224 patent were indefinite because in-
    fringement of the “hidden from a view” limitation depend-
    ed on an arbitrary location of a viewer, which was not
    identified in the ’224 patent.
    6                         QUALITY EDGE, INC.   v. ROLLEX CORP.
    Based on its claim construction, the district court
    granted summary judgment of infringement in favor of
    Quality Edge, finding that the only claim limitation
    Rollex challenged—“a generally horizontal imperforate
    top wall”—was found in the accused Stealth Soffit™. See
    Quality Edge, Inc. v. Rollex Corp., No. 1:10-cv-278, 
    2013 WL 3283639
    , at *6–9 (W.D. Mich. June 28, 2013) (“Sum-
    mary Judgment Decision”). The district court also denied
    Rollex’s cross-motion for summary judgment of indefi-
    niteness. 
    Id. at *9–12.
    The district court also denied
    several evidentiary and discovery motions, including
    Rollex’s (1) motion for leave to submit an expert declara-
    tion in support of its motion for summary judgment on
    indefiniteness, (2) motion for leave to conduct discovery,
    (3) motion for leave to submit an expert declaration in
    opposition to Quality Edge’s summary judgment motion
    on infringement and validity, and (4) motion for leave to
    supplement its opposition to Quality Edge’s summary
    judgment motion on infringement and validity. 
    Id. at *13–16.
        After the district court granted summary judgment of
    infringement, Quality Edge moved for a permanent
    injunction and for the dismissal of Rollex’s invalidity
    defenses and counterclaim. The district court granted the
    permanent injunction after finding that each of the fac-
    tors set forth in eBay Inc. v. MercExchange, L.L.C., 
    547 U.S. 388
    , 391 (2006)—irreparable injury, inadequacy of
    monetary damages, balance of hardships, and public
    interest—favored injunctive relief. See Quality Edge, Inc.
    v. Rollex Corp., No. 1:10-cv-278, 
    2016 WL 4536327
    , at *1–
    6 (W.D. Mich. Aug. 31, 2016). The district court also held
    that Rollex’s invalidity counterclaims failed to meet the
    pleadings standards under Ashcroft v. Iqbal, 
    556 U.S. 662
    (2009) and Bell Atlantic Corp. v. Twombly, 
    550 U.S. 544
    (2007). See Quality Edge, Inc. v. Rollex Corp., No. 1:10-cv-
    278, 
    2015 WL 4392980
    , at *1–2 (W.D. Mich. July 15,
    2015) (“Invalidity Defenses Decision”). Likewise, the
    QUALITY EDGE, INC.   v. ROLLEX CORP.                      7
    district court held that Rollex’s invalidity defenses failed
    under the Sixth Circuit’s “fair notice” pleading standard.
    
    Id. at *3–4.
    Accordingly, the district court dismissed
    Rollex’s invalidity counterclaim and affirmative defenses
    without leave to amend.
    Rollex appeals. We have jurisdiction pursuant to
    28 U.S.C. § 1295(a)(1).
    DISCUSSION
    I.
    We begin by addressing claim construction. We con-
    clude that the district court erred in construing the claim
    phrase “a generally horizontal imperforate top wall” to
    mean “[d]efined by a generally horizontal imperforate top
    wall, wherein any perforations in the top wall are hidden
    from a view underneath the eaves.” Claim Construction
    Decision, 
    2012 WL 1790026
    , at *7 (alteration in original).
    We review the district court’s ultimate claim construc-
    tion de novo and review underlying factual findings based
    on extrinsic evidence for clear error. See Medgraph, Inc.
    v. Medtronic, Inc., 
    843 F.3d 942
    , 949 (Fed. Cir. 2016)
    (citing Teva Pharm. USA, Inc. v. Sandoz, Inc., 
    135 S. Ct. 831
    , 841 (2015)). Claim construction aims to “ascribe the
    ‘ordinary and customary meaning’ to claim terms as they
    would be understood to a person of ordinary skill in the
    art at the time of invention.” Liberty Ammunition, Inc. v.
    United States, 
    835 F.3d 1388
    , 1395 (Fed. Cir. 2016) (quot-
    ing Phillips v. AWH Corp., 
    415 F.3d 1303
    , 1312 (Fed. Cir.
    2005) (en banc). “[T]he person of ordinary skill in the art
    is deemed to read the claim term not only in the context of
    the particular claim in which the disputed term appears,
    but in the context of the entire patent, including the
    specification.” 
    Phillips, 415 F.3d at 1313
    .
    As the district court recognized, the plain and ordi-
    nary meaning of “imperforate” is “having no opening or
    aperture” and “lacking perforations.” Claim Construction
    8                         QUALITY EDGE, INC.   v. ROLLEX CORP.
    Decision, 
    2012 WL 1790026
    , at *5 (citing Webster’s Ninth
    New Collegiate Dictionary 604, 873 (9th ed. 1988)).
    Nonetheless, the district court did not interpret “generally
    horizontal imperforate top wall” to require a top wall
    without openings or apertures. Instead, the district court
    concluded that the term “generally,” which precedes the
    term “horizontal,” also modifies “imperforate,” allowing
    for some holes in the top wall.
    The district court correctly noted that “generally” is a
    ubiquitous term in patent claims, used to signal approxi-
    mation. The central issue, however, is whether “general-
    ly” in the claim phrase modifies only “horizontal” or
    whether it modifies both “horizontal” and “imperforate.”
    We disagree with the district court’s conclusion that
    “generally” modifies both horizontal and imperforate. We
    conclude that, in light of the claims and specification of
    the ’224 patent, the more reasonable reading of the claim
    term “generally horizontal imperforate” is that the term
    “generally” only modifies “horizontal” and does not modify
    the strict boundary of “imperforate.”
    The absolute nature of the claim term “imperforate”
    supports our conclusion. It makes little sense as a tech-
    nical matter to have a “generally” imperforate wall. A
    wall is either perforate (with holes) or imperforate (with-
    out holes). Once a wall is “generally” imperforate, it is
    actually perforate.
    Claim 23, which depends from claim 1, further sup-
    ports our construction.          As we have recognized,
    “[a]lthough each claim is an independent invention,
    dependent claims can aid in interpreting the scope of
    claims from which they depend.” Laitram Corp. v. NEC
    Corp., 
    62 F.3d 1388
    , 1392 (Fed. Cir. 1995). Here, depend-
    ent claim 23 recites “said imperforate top wall.” ’224
    patent at col. 6 ll. 40–41. It does not recite “said generally
    imperforate top wall.” This suggests that “generally” in
    claim 1 does not modify “imperforate.”
    QUALITY EDGE, INC.   v. ROLLEX CORP.                       9
    Our construction is also consistent with the patent
    specification, which is “the single best guide to the mean-
    ing of a disputed term” and “[u]sually . . . is dispositive.”
    
    Phillips, 415 F.3d at 1315
    . In all but one instance, the
    specification describes “a horizontal imperforate top wall”
    without the use of “generally” to modify either term in the
    claim phrase. See ’224 patent, Abstract, col. 1 ll. 42–43,
    col. 2 l. 66. Only once does the specification use the
    phrase “a generally horizontal imperforate top wall.” See
    
    id. at col.
    1 l. 59. But the specification more specifically
    explains that the top wall has a “generally horizontal
    orientation” when installed under an eave. See 
    id. at col.
    3 ll. 39–40. This signals that the inventors intended
    the term “generally” in the claims to refer only to the
    “horizontal” orientation of the top wall. Nowhere does the
    specification describe or depict a top wall with holes or
    perforations.
    The district court emphasized that the specification
    states that the top wall “is substantially imperforate.”
    Claim Construction Decision, 
    2012 WL 1790026
    , at *6
    (citing ’224 patent col. 3 ll. 34–36). The district court
    concluded that the specification’s use of the term “sub-
    stantially imperforate” “clearly expresses that the top
    wall may have perforations” and “[t]o find otherwise
    blindly disregards the presence and purpose of the modi-
    fiers ‘substantially’ and ‘visually detectable.’” 
    Id. We respectfully
    disagree.
    Quality Edge and the district court overlook the re-
    mainder of this sentence in the specification, which re-
    cites that the top wall “is substantially imperforate, and
    therefore does not permit air to pass therethrough.”
    ’224 patent col. 3 ll. 34–35 (emphasis added). The patent
    therefore qualifies “substantially imperforate” by stating
    that the top wall must not permit air to pass through.
    Logically, if the top wall were substantially imperforate
    such that it had some holes, as Quality Edge argues, the
    10                          QUALITY EDGE, INC.   v. ROLLEX CORP.
    top wall would permit air to pass through, which contra-
    dicts the express definition provided in the specification.
    Additionally, the beginning of this very sentence ex-
    plains that the description that follows describes the
    invention as illustrated in Figures 1–3 of the patent. 
    Id. at col.
    3 ll. 33–34 (“In the example illustrated in FIGS. 1–
    3, the top wall 6 . . . is substantially imperforate.”). But
    as can be seen in each of the figures, the top wall has no
    perforations, which is consistent with the specification’s
    disclosure of an imperforate top wall. Accordingly, we
    conclude that the specification of the ’224 patent more
    reasonably supports the conclusion that “imperforate,” as
    used in the claims, requires a top wall that has no holes
    or perforations.
    We also disagree with the grammatical argument ad-
    vanced by the district court. The district court empha-
    sized that because an earlier limitation in claim 1—“a
    generally flat, imperforate base portion”—contains a
    comma, the lack of a comma between “horizontal” and
    “imperforate” in the disputed claim limitation indicates
    that “generally” modifies both “horizontal” and “imperfo-
    rate,” such that the top wall is both generally horizontal
    and generally imperforate. Claim Construction Decision,
    
    2012 WL 1790026
    , at *4. As the district court recognized,
    however, there is no hard and fast grammatical rule that
    placing a comma between two adjectives means that the
    adverb does not modify both adjectives. 
    Id. Similarly, there
    is no hard and fast grammatical rule that not plac-
    ing a comma between two adjectives means that the
    adverb modifies both adjectives. This is demonstrated by
    the fact that the comma in the phrase “a generally flat,
    imperforate base portion” is not used consistently in the
    specification. The specification repeatedly uses the same
    phrase as the claims, referring to “a generally flat imper-
    forate base portion,” but without a comma.                   See
    ’224 patent, Abstract, col. 1 ll. 37–38, col. 1 ll. 52–53, col. 2
    ll. 60–61. In fact, the only two instances in which the
    QUALITY EDGE, INC.   v. ROLLEX CORP.                     11
    comma appears in the phrase are in independent claims 1
    and 42. Thus, we conclude that the lack of a comma
    between the adjectives “horizontal” and “imperforate”
    does not demonstrate that “generally” modifies both
    “horizontal” and “imperforate.”
    For these reasons, we agree with Rollex that the cor-
    rect construction of the phrase is “a top wall that has a
    generally horizontal orientation, when the vented soffit
    panel is installed under an eave, and does not include any
    perforations therein.” J.A. 373.
    Because we find that the asserted claims require that
    the top wall not include any perforations and there is no
    dispute that Rollex’s accused Stealth Soffit™ is inundated
    with perforations in its top wall, we vacate the district
    court’s summary judgment of infringement and its per-
    manent injunction order. We do not reach Rollex’s argu-
    ment that the claims as construed by the district court are
    indefinite as it is moot in light of our claim construction.
    II.
    We next turn to Rollex’s arguments regarding the dis-
    trict court’s denial of its invalidity counterclaim and
    affirmative defenses. We affirm the district court’s rul-
    ings.
    We apply the law of the regional circuit, in this case
    the Sixth Circuit, when reviewing a district court’s ruling
    on a motion to dismiss for failure to state a claim or a
    motion for leave to amend. See CoreBrace LLC v. Star
    Seismic LLC, 
    566 F.3d 1069
    , 1072 (Fed. Cir. 2009); Ulti-
    max Cement Mfg. Corp. v. CTS Cement Mfg. Corp., 
    587 F.3d 1339
    , 1354 (Fed. Cir. 2009). In the Sixth Circuit, a
    district court’s decision to grant a motion to dismiss for
    failure to state a claim is reviewed de novo, see Agema v.
    City of Allegan, 
    826 F.3d 326
    , 331 (6th Cir. 2016), and its
    denial for leave to amend is reviewed for an abuse of
    12                        QUALITY EDGE, INC.   v. ROLLEX CORP.
    discretion, see Glazer v. Chase Home Fin. LLC, 
    704 F.3d 453
    , 458 (6th Cir. 2013).
    In its Answer to Quality Edge’s Complaint, Rollex as-
    serted a defense that “[t]he ’224 Patent . . . is invalid
    because it does not comply with the statutory require-
    ments of patentability enumerated in, inter alia,
    35 U.S.C. §§ 101, 102, 103, 112, 116 and/or 132.” J.A. 237.
    Rollex also counterclaimed, alleging that “[t]he ’224
    Patent . . . is invalid for failure to satisfy one or more of
    the conditions of patentability set forth in Title 35, includ-
    ing, inter alia, 35 U.S.C. §§ 101, 102, 103, 112, 116 and/or
    132.” J.A. 240 ¶ 12. At no point during the litigation did
    Rollex allege any facts in support of its invalidity counter-
    claim or defenses.
    The district court held that the Twombly/Iqbal plead-
    ing standards applied to Rollex’s counterclaims and that
    the Sixth Circuit’s “fair notice” standard applied to its
    defenses. See Invalidity Defenses Decision, 
    2015 WL 4392980
    , at *1. 2 Under these standards, the district court
    dismissed Rollex’s counterclaims and defenses, finding
    that “[t]he counterclaim provides no further facts or
    context to identify the claims of invalidity beyond merely
    citing sections of the patent statute” and that its “coun-
    terclaim falls far short of the Iqbal and Twombly pleading
    standard.” 
    Id. at *1,
    *2. With respect to its defenses, the
    district court found that “Rollex’s barebones, boilerplate
    affirmative defenses do not provide Quality Edge ‘fair
    notice’ of the nature of the defenses.” 
    Id. at *3.
    The court
    therefore dismissed the counterclaim and defenses with-
    out leave to amend because Rollex’s “undue delay, undue
    prejudice and futility all weigh[ed] against leave to
    2  Rollex does not contest the district court’s ruling
    regarding the pleading requirements for its invalidity
    counterclaim or defenses, and therefore we need not reach

    amend” and because “Rollex’s motion [was] belated,
    wasteful of resources, and unduly prejudicial to Quality
    Edge.” 
    Id. at *4.
         Upon reviewing the record, we find no abuse of discre-
    tion in the district court’s dismissal of Rollex’s invalidity
    counterclaim and defenses. Rollex’s invalidity counter-
    claim merely recites various sections of the patent statute
    with no supporting facts, and its defenses are similarly
    boilerplate without factual support. We note that the
    district court on multiple occasions warned Rollex that its
    counterclaim and defenses were insufficient and required
    supplementation, but to no avail. At the outset of the
    litigation, Rollex pursued only its non-infringement case
    and only belatedly asserted indefiniteness after the
    district court’s claim construction, which the district court
    fortuitously addressed. Despite the district court’s con-
    tinued attempts to ascertain Rollex’s other invalidity
    positions, Rollex failed to present them or request leave to
    further amend its invalidity counterclaim and defenses
    until after the district court entered summary judgment
    on infringement.
    While Federal Rule of Civil Procedure 15(a)(2) pro-
    vides that the district court “should freely give leave [to
    amend] when justice so requires,” the Sixth Circuit has
    recognized that a district court may deny leave due to
    “[u]ndue delay in filing, lack of notice to the opposing
    party, bad faith by the moving party, repeated failure to
    cure deficiencies by previous amendments, undue preju-
    dice to the opposing party, and futility of amendment.”

    1989) (citing Hageman v. Signal L.P. Gas, Inc., 
    486 F.2d 479
    , 484 (6th Cir. 1973)). Here, we cannot say that the
    district court abused its discretion in concluding that
    Rollex’s conduct constitutes undue delay and prejudice,
    supporting the district court’s discretion to dismiss its
    invalidity counterclaim and defenses without leave to
    14                         QUALITY EDGE, INC.   v. ROLLEX CORP.
    amend. Accordingly, we affirm the district court’s dismis-
    sal of Rollex’s invalidity counterclaim and defenses.
    III.
    Lastly, Rollex seeks reassignment of this case to a dif-
    ferent district judge on remand. We deny such extraordi-
    nary relief.
    A request for reassignment is not unique to the patent
    laws, but is procedural in nature. We therefore review
    such a request under the law of the regional circuit, here
    the Sixth Circuit. See Micro Chem., Inc. v. Lextron, Inc.,
    
    318 F.3d 1119
    , 1122 (Fed. Cir. 2003). The Sixth Circuit
    has held that reassignments are “an extraordinary power
    and should rarely be invoked . . . [and should be] made
    infrequently and with the greatest reluctance.” Armco,
    Inc. v. United Steelworkers of Am., AFL-CIO, Local 169,
    
    280 F.3d 669
    , 683 (6th Cir. 2002) (citation omitted).
    Factors relevant to considering reassignment include:
    (1) whether the original judge would reasonably
    be expected upon remand to have substantial dif-
    ficulty in putting out of his or her mind previous-
    ly-expressed views or findings determined to be
    erroneous or based on evidence that must be re-
    jected, (2) whether reassignment is advisable to
    preserve the appearance of justice, and (3) wheth-
    er reassignment would entail waste and duplica-
    tion out of proportion to any gain in preserving
    the appearance of fairness.
    
    Id. Rollex believes
    that the district court will not be
    impartial on remand based on its denial of Rollex’s dis-
    covery requests and submission of expert testimony on
    summary judgment, its denial of Rollex’s evidence at the
    permanent injunction stage, its striking of its invalidity
    counterclaim and affirmative defenses, and its chastise-
    QUALITY EDGE, INC.   v. ROLLEX CORP.                      15
    ment of Rollex based on its change of its litigation posi-
    tions and delay of litigation.
    We find no principled reason for reassigning this case.
    As the district court properly held, Rollex shaped the
    course of this case from the beginning, conceding that the
    single dispositive issue was the claim construction of “a
    generally horizontal imperforate top wall” and in turn
    noninfringement based on this single claim limitation.
    Rollex agreed that this issue could be resolved on sum-
    mary judgment without discovery. We note that we have
    now adopted Rollex’s claim construction, which will be the
    proper construction for the infringement analysis on
    remand. Rollex also agreed that discovery during the
    injunction stage was unnecessary. The district court
    merely relied on Rollex’s representations, which formed
    the course of the litigation.
    Considering Rollex’s concessions, we conclude that the
    district court did not abuse its discretion in denying
    Rollex’s motions for discovery and additional evidence.
    Likewise, for the reasons stated earlier, the district court
    did not err in dismissing Rollex’s unsupported invalidity
    counterclaim and defenses. Accordingly, we have no
    reason to believe that the district judge will have substan-
    tial difficulty in disregarding her previous views and
    findings on remand.        Moreover, reassignment would
    entail waste and duplication of the parties’ and the dis-
    trict court’s resources in this already prolonged litigation.
    We therefore deny Rollex’s request for reassignment.
    IV.
    We have considered Rollex’s additional arguments
    and find them unpersuasive. In sum, we vacate the
    district court’s claim construction of “a generally horizon-
    tal imperforate top wall” and construe the term to mean
    “a top wall that has a generally horizontal orientation,
    when the vented soffit panel is installed under an eave,
    and does not include any perforations therein.” As a
    16                        QUALITY EDGE, INC.   v. ROLLEX CORP.
    result, we vacate the district court’s summary judgment of
    infringement and its permanent injunction order. We
    affirm the district court’s dismissal of Rollex’s invalidity
    counterclaim and defenses and deny Rollex’s request for
    reassignment. Finally, we remand to the district court for
    further proceedings consistent with this opinion.
