    Plaintiff-Appellant Realtime Adaptive Streaming LLC
    (Realtime) filed three separate patent infringement actions
    against Defendants-Cross-Appellants Netflix, Inc. and
    Netflix Streaming Services, Inc. (collectively, Netflix).
    Realtime first asserted six patents in the District of Dela-
    ware. While the Delaware action was ongoing, Netflix filed
    seven petitions for inter partes review before the Patent
    Trial and Appeal Board seeking a determination that many
    of the claims asserted in the Delaware action were un-
    patentable. Netflix also moved to dismiss the complaint for
    failure to state a claim, arguing that four of the six asserted
    patents were ineligible under 
    35 U.S.C. § 101
    . Netflix fully
    briefed, and Realtime full responded to, those patent-ineli-
    gibility theories. Following institution of all seven inter
    partes review proceedings and a thorough report and rec-
    ommendation from the Delaware magistrate judge finding
    claims of four of the patents ineligible under § 101,
    Realtime voluntarily dismissed the Delaware action—be-
    fore the district court could rule on the magistrate judge’s
    ineligibility findings.
    Although Realtime was done with Delaware, it was not
    done with Netflix. The next day, Realtime started fresh,
    re-asserting the same six patents against Netflix, this time
    in the Central District of California—despite having previ-
    ously informed the Delaware court that transferring the
    Delaware action across the country to the Northern Dis-
    trict of California would be inconvenient and an unfair bur-
    den on Realtime. Netflix then simultaneously moved for
    attorneys’ fees and to transfer the California actions back
    to Delaware. Prior to a decision on either motion, Realtime
    again avoided any court ruling by voluntarily dismissing
    its case.
    Case: 21-1484     Document: 76     Page: 3     Filed: 07/27/2022
    REALTIME ADAPTIVE STREAMING    v. NETFLIX, INC.             3
    Netflix then renewed its motion for attorneys’ fees for
    the California actions as well as the related Delaware ac-
    tion and inter partes review proceedings. The district court
    awarded fees for both California actions pursuant to § 285
    and, in the alternative, the court’s inherent equitable pow-
    ers. The district court declined to award fees for the related
    Delaware action or inter partes review proceedings under
    either § 285 or Federal Rule of Civil Procedure 41(d). 1
    Realtime now appeals the court’s fee award for the Califor-
    nia actions and Netflix cross-appeals the court’s denial of
    fees for the related proceedings. Because we hold that the
    district court did not abuse its discretion in awarding fees
    pursuant to its inherent equitable powers or in denying
    fees for the related proceedings, we affirm. We need not
    reach the question of whether the award also satisfies the
    requirements of § 285. 2
    1    The parties dispute whether Rule 41(d) permits a
    district court to award attorneys’ fees. However, as we ex-
    plain below, because we affirm the district court’s decision
    to not award fees for the non-California proceedings, we
    need not decide the issue.
    2   Section 285 permits a court to award attorneys’
    fees in “exceptional cases” to “the prevailing party.” On ap-
    peal, Realtime challenges whether its two voluntary dis-
    missals rendered Netflix a prevailing party. But we need
    not resolve that question here. A district court may rely on
    its inherent equitable powers to award attorneys’ fees even
    if there is a statutory provision creating an alternative ve-
    hicle. Chambers v. NASCO, Inc., 
    501 U.S. 32
    , 46 (1991)
    (“We discern no basis for holding that the sanctioning
    scheme of the statute and the rules displaces the inherent
    power to impose sanctions for the bad-faith conduct de-
    scribed above.”); 
    id. at 49
     (“The Court’s prior cases have in-
    dicated that the inherent power of a court can be invoked
    even if procedural rules exist which sanction the same

    I
    The parties have been adverse in three district court
    actions and seven inter partes review proceedings involving
    the same six patents and the same accused products.
    The events leading to the award of attorneys’ fees at
    issue began on November 21, 2017, when Realtime filed a
    patent infringement action against Netflix in the District
    of Delaware. J.A. 3672–3742. In the Delaware action,
    Realtime asserted six patents: U.S. Patent Nos. 7,386,046
    (’046 patent); 8,634,462 (’462 patent); 8,934,535 (’535 pa-
    tent); 9,578,298 (’298 patent); 9,762,907 (’907 patent); and
    9,769,477 (’477 patent). J.A. 3674. The ’462 patent later
    reissued as U.S. Patent No. RE46,777 (’777 patent).
    J.A. 354. In response, Netflix moved to dismiss the com-
    plaint, arguing not only that Realtime failed to sufficiently
    plead direct, contributory, and induced infringement, but
    also that four of the six patents were ineligible under
    35 U.S.C § 101. 3 J.A. 816. While the motion to dismiss was
    pending, Netflix moved to transfer the case to the Northern
    District of California for convenience and Realtime op-
    posed. In its opposition brief, Realtime vehemently argued
    that it lacked any ties to California and that moving the
    case to California would “lead to greater expense, addi-
    tional travel, and more work for Realtime,” leading to an
    conduct.”); see also Miller v. Cardinale, 
    361 F.3d 539
    , 551
    (9th Cir. 2004) (footnote omitted) (“The Supreme Court has
    emphatically rejected the notion that the advent of
    
    28 U.S.C. § 1927
     and the sanctioning provisions in the Fed-
    eral Rules of Civil Procedure displaced the inherent power
    to impose sanctions for bad faith conduct.” (citing Cham-
    bers, 
    501 U.S. at
    49–50)).
    3   Netflix identified the ’535, ’477, ’907, and ’046 pa-
    tents as ineligible under § 101.
    Case: 21-1484     Document: 76      Page: 5    Filed: 07/27/2022
    REALTIME ADAPTIVE STREAMING    v. NETFLIX, INC.              5
    “unfair” burden on Realtime. J.A. 3813–14; J.A. 3817. The
    Delaware court denied the motion to transfer. J.A. 612.
    Then, on December 12, 2018, the Delaware magistrate
    judge, after full briefing by the parties, issued a detailed
    report and recommendation advising the court to find the
    four patents challenged under § 101 to be ineligible.
    J.A. 975–85. In that report, the magistrate judge sepa-
    rately analyzed representative claims from each of the four
    challenged patents under the two-step framework set forth
    by the Supreme Court. The magistrate judge considered
    both parties’ arguments and compared the challenged
    claims to this court’s precedent, setting forth a thorough,
    fully reasoned analysis for why the asserted claims were
    directed to an ineligible abstract idea. J.A. 968–85.
    Realtime subsequently moved to amend its complaint.
    J.A. 3961–74. In that motion, Realtime pointed to its re-
    lated patents that purportedly showed “various technolo-
    gists were still struggling to solve” the problem identified
    in the asserted patents. J.A. 3968. However, in parallel
    actions involving different defendants, the same district
    court judge invalidated all of those related patents, finding
    them to be directed to ineligible subject matter.
    J.A. 3995–96. The same order from the parallel actions
    also denied Realtime’s earlier motions to amend its com-
    plaints “for futility.” J.A. 3996.
    If the mounting threat of ineligibility for four of the pa-
    tents were not enough, beginning from January to May of
    2019, the Patent Trial and Appeal Board began instituting
    inter partes review proceedings for all six of the asserted
    patents on a rolling basis. J.A. 6005–33 (instituting inter
    partes review for the ’535 patent); J.A. 6061–6106 (for the
    ’298 patent); J.A. 6034–60 (for the ’777 patent); J.A. 6106–
    43 (for the ’477 patent); J.A. 5874–5907 (for the ’907 pa-
    tent);    J.A.   5908–68      (for    the     ’477     patent);
    J.A. 5969–6004 (for the ’046 patent).

    6              REALTIME ADAPTIVE STREAMING    v. NETFLIX, INC.
    By little coincidence, on July 22, 2019, right after the
    district court found Realtime’s related patents in the par-
    allel actions to be ineligible under § 101, but before the
    same district court could rule on the magistrate judge’s in-
    eligibility recommendation for these patents, Realtime vol-
    untarily dismissed its Delaware action. J.A. 4000.
    For most plaintiffs, these circumstances would signal
    the end of litigation. Realtime, however, rebooted the liti-
    gation against Netflix in the form of two new patent in-
    fringement actions in the Central District of California—a
    forum that by that time had already reached a more favor-
    able conclusion on patent-eligibility for some of the claims.
    Realtime Adaptive Streaming LLC v. Netflix, Inc., No. 2:19-
    cv-06359, 
    2020 WL 8024356
    , at *7 (C.D. Cal. Nov. 23, 2020)
    (Fees Award); see also Realtime Adaptive Streaming LLC v.
    Google LLC, No. 2:18-cv-03629 (C.D. Cal. Oct. 25, 2018),
    Dkt. No. 36. The first complaint asserted the ’298 patent
    and the ’777 reissue of the ’462 patent, J.A. 55, and the sec-
    ond complaint asserted the four patents the Delaware mag-
    istrate judge recommended finding ineligible under § 101,
    J.A. 108. In effect, Realtime divided the Delaware action
    in two—asserting the same patents, but sequestering the
    patents known to be vulnerable under § 101. By heading
    to California, Realtime dodged the adverse magistrate rec-
    ommendation under consideration by the district court
    judge who had already found five related patents to be in-
    eligible.
    Shortly thereafter, Netflix simultaneously moved to
    transfer both California actions back to Delaware and for
    attorneys’ fees. J.A. 38; J.A. 46–47. Realtime again op-
    posed the transfer, this time arguing that California was
    more convenient than Delaware despite: (1) the Delaware
    Case: 21-1484     Document: 76      Page: 7    Filed: 07/27/2022
    REALTIME ADAPTIVE STREAMING    v. NETFLIX, INC.              7
    court’s experience with most of the asserted patents, 4
    (2) Realtime’s original selection of that forum, and
    (3) Realtime’s earlier protests in the Delaware action that
    a transfer to California would be an unfair burden. See,
    e.g., J.A. 3365. Following briefing on the motion to transfer
    (and the day before oral argument on that motion), but be-
    fore the parties fully briefed the fees motion, Realtime vol-
    untarily dismissed both California actions. J.A. 3615;
    J.A. 3618. At the time of the dismissals, the California
    court had not yet made any substantive determinations.
    After this second round of voluntary dismissals, Netflix
    renewed its motion for attorneys’ fees for: (1) the Califor-
    nia actions, (2) the original Delaware action, and (3) the re-
    lated inter partes review proceedings. J.A. 3620–70;
    J.A. 4881–83. The California court awarded fees for the
    California actions but declined to award fees for the related
    Delaware and inter partes review proceedings. Fees Award
    at *10. In particular, the court concluded that Realtime’s
    litigation conduct justified awarding fees for the California
    actions under either § 285 or the court’s inherent equitable
    powers. Id. at *11. For the related actions, the court con-
    cluded that an award of fees was not warranted under ei-
    ther § 285 or Rule 41(d). Id. at *10.
    This appeal and cross-appeal followed. We have juris-
    diction under 
    28 U.S.C. § 1295
    (a)(1).

    A district court “may award attorneys’ fees when the
    interests of justice so require.” Hall v. Cole, 
    412 U.S. 1
    , 4–5
    (1973). The Supreme Court has repeatedly recognized the
    propriety of such an award when a party has “acted in bad
    faith, vexatiously, wantonly, or for oppressive reasons.”
    4   On September 20, 2019, Realtime added previ-
    ously-unasserted 
    U.S. Patent No. 8,054,879
     to one of the
    California actions.

    8              REALTIME ADAPTIVE STREAMING    v. NETFLIX, INC.
    Chambers, 
    501 U.S. at
    45–46 (quoting Alyeska Pipeline
    Serv. Co. v. Wilderness Soc’y, 
    421 U.S. 240
    , 258–59 (1975));
    see also Roadway Express, Inc. v. Piper, 
    447 U.S. 752
    , 766
    (1980). Because a district court’s inherent power to impose
    sanctions in the form of attorneys’ fees is not a substantive
    patent question, we apply the law of the regional circuit,
    here, the Ninth Circuit. AntiCancer, Inc. v. Pfizer, Inc., 
    769 F.3d 1323
    , 1328 (Fed. Cir. 2014). Under Ninth Circuit
    precedent, the court must find that the sanctioned behavior
    “constituted or was tantamount to bad faith.” Haeger v.
    Goodyear Tire & Rubber Co., 
    793 F.3d 1122
    , 1132 (9th Cir.
    2015) (quoting Leon v. IDX Sys. Corp., 
    464 F.3d 951
    , 961
    (9th Cir. 2006)), rev’d on other grounds, 
    137 S. Ct. 1178
    (2017). A determination that a party has engaged in “will-
    ful actions” with “an improper purpose” can satisfy the bad
    faith requirement. Fink v. Gomez, 
    239 F.3d 989
    , 993–94
    (9th Cir. 2001). Such actions include “a full range of litiga-
    tion abuses,” such as “delaying or disrupting the litigation,”
    Haeger, 793 F.3d at 1133 (first quoting Chambers, 
    501 U.S. at 47
    ; and then Primus Auto. Fin. Servs., Inc. v. Batarse,
    
    115 F.3d 644
    , 648 (9th Cir. 1997)), and can include actions
    consisting of “making a truthful statement or a non-frivo-
    lous argument or objection” for an improper purpose, Fink,
    
    239 F.3d at 992
    . However, a finding that a party engaged
    in bad faith conduct does not compel the imposition of sanc-
    tions, which “is within the sound discretion of the district
    court.” Haeger, 793 F.3d at 1131 (quoting Lasar v. Ford
    Motor Co., 
    399 F.3d 1101
    , 1109 (9th Cir. 2005)).
    We also apply Ninth Circuit law to an award or denial
    of “costs” pursuant to Rule 41(d). See Shum v. Intel Corp.,
    
    629 F.3d 1360
    , 1370 (Fed. Cir. 2010) (citing Manildra Mill-
    ing Corp. v. Ogilvie Mills, Inc., 
    76 F.3d 1178
    , 1184
    (Fed. Cir. 1996)). Under Rule 41(d) a district court “may”
    award costs “if a plaintiff who previously dismissed an ac-
    tion in any court files an action based on or including the
    same claim against the same defendant.”

    REALTIME ADAPTIVE STREAMING    v. NETFLIX, INC.             9
    Federal Circuit precedent applies to a district court’s
    decision to award fees pursuant to § 285. Blackbird Tech
    LLC v. Health in Motion LLC, 
    944 F.3d 910
    , 914 (Fed. Cir.
    2019) (“We apply Federal Circuit case[]law to the § 285
    analysis, as it is unique to patent law.” (quoting Digeo, Inc.
    v. Audible, Inc., 
    505 F.3d 1362
    , 1366 (Fed. Cir. 2007))). Un-
    der § 285, a district court “may award” attorneys’ fees to
    “the prevailing party” in “exceptional cases.”
    Both the Ninth Circuit and this court review a district
    court’s decision regarding whether to award fees for abuse
    of discretion. Haeger, 793 F.3d at 1130 (reviewing a district
    court’s award of attorneys’ fees pursuant to its inherent
    powers for abuse of discretion); Arunachalam v. IBM, 
    989 F.3d 988
    , 996 (Fed. Cir. 2021) (same); Blackbird Tech, 944
    F.3d at 914 (reviewing a district court’s award of attorneys’
    fees pursuant to § 285 for abuse of discretion); cf. Draper v.
    Rosario, 
    836 F.3d 1072
    , 1087 (9th Cir. 2016) (reviewing a
    district court’s award of costs pursuant to Federal Rule of
    Civil Procedure 54(d)(1) for abuse of discretion).
    Accordingly, we will not overturn the district court’s
    decision regarding whether to award attorneys’ fees “un-
    less the court committed an error of law or the court’s fac-
    tual determinations were clearly erroneous.”        Lasar,
    399 F.3d at 1109; see also Blackbird Tech, 944 F.3d at 914.
    III
    A
    The district court awarded Netflix attorneys’ fees for
    both California actions pursuant to its inherent equitable
    powers. Fees Award at *11. The district court reasonably
    found Realtime’s conduct in the California actions “im-
    proper,” “exceptional,” and “totally unjustified.” Id. at *6.
    When Realtime renewed its lawsuit in California, Realtime
    had in hand: (1) the Delaware magistrate judge’s report
    recommending the court find that claims of four asserted
    patents were ineligible under § 101, (2) the Delaware
    Case: 21-1484    Document: 76      Page: 10    Filed: 07/27/2022
    10             REALTIME ADAPTIVE STREAMING    v. NETFLIX, INC.
    judge’s ruling in parallel actions that five related patents
    (that Realtime claimed helped its cause) were themselves
    patent-ineligible, and (3) Patent Trial and Appeal Board
    decisions instituting inter partes review proceedings, indi-
    cating that Netflix had demonstrated a reasonable likeli-
    hood of success in proving at least one claim of each patent
    unpatentable. Id. The district court also noted that
    Realtime knew, upon filing the California actions, that the
    Central District of California had recently “reached a more
    favorable ruling regarding the patent eligibility of [the
    same four patents] in another case.” Id. at *7. Realtime
    undoubtedly realized that by refiling in California, it could
    effectively erase the Delaware magistrate judge’s fulsome
    and compelling patent-ineligibility analysis and findings.
    In addition to Realtime’s efforts to avoid an adverse pa-
    tent-eligibility determination, Realtime also resisted
    transfer back to the forum it originally chose. Contrary to
    earlier arguments that litigation should remain in Dela-
    ware because litigating in California would be inconven-
    ient, id., and, in fact, “unfair,” J.A. 3813–14, Realtime
    refiled in California. It then fought transfer back to Dela-
    ware, arguing that relevant witnesses and evidence are in
    California and that Delaware would not be more conven-
    ient. J.A. 3365–68. Realtime also argued that judicial
    economy weighed against transfer back to Delaware de-
    spite that district court’s experience with, and now-wasted
    substantive     analysis     of,   the    asserted    patents.
    J.A. 3369–70; see also Fees Award at *8. The district court
    correctly highlighted these contradictions to support a find-
    ing of “impermissible forum shopping.”
    Ultimately, Realtime was aware “that its lawsuit in
    Delaware was undeniably tanking,” making its decision to
    “run off to another jurisdiction in hopes of getting a more
    favorable forum [] totally unjustified,” and “improper.”
    Fees Award at *6–7.

    REALTIME ADAPTIVE STREAMING    v. NETFLIX, INC.            11
    The district court therefore reasonably concluded that
    “Realtime’s conduct in forum shopping its dispute supports
    invocation” of its equitable powers. Id. In so finding, the
    district court compared this case to persuasive authority
    from the District Court for the District of Columbia. Ap-
    plying a “bad faith” standard similar to that required in the
    Ninth Circuit, that court awarded attorneys’ fees pursuant
    to its inherent powers because the plaintiff engaged in sim-
    ilarly “blatant forum-shopping” by refiling the suit in a dif-
    ferent forum after it lost and then resisting transfer back
    to the original court to avoid an adverse result. Id. (citing

    1997 WL 411654
     (D.C. Cir. June 30, 1997)).
    The district court also considered and properly rejected
    Realtime’s purported justifications for its near-immediate
    refiling maneuver. First, the district court correctly found
    that a then-recent Federal Circuit § 101 decision did not
    justify Realtime’s decision to dismiss the Delaware action
    and refile in California. Id. Second, the district court rea-
    sonably found that Realtime’s alleged interest in a “speed-
    ier decision” was “nonsensical” because it moved the case
    from a forum where the litigation was underway, and as-
    signed to a judge familiar with related patents, to a court
    both unfamiliar with the case and “severely understaffed.”
    Id. at *7 n.12.
    Instead, the facts indicated Realtime only changed
    course following the adverse patentability decision from
    the same Delaware judge in parallel actions, an indicator
    the judge was likely to adopt the magistrate’s detailed
    analysis in this case. Id. at *7. The district court found
    that the timing made it “abundantly clear that Realtime
    had been holding out for a favorable decision” in the paral-
    lel action, but then “realized the writing was on the wall”
    following that adverse decision. Id.

    While we agree with Realtime that it is generally per-
    missible under Rule 41(a)(1)(A)(i) for a plaintiff to volun-
    tarily dismiss an action and refile the case in another
    forum, that is a woefully incomplete description of the cir-
    cumstances of this case. As described above, Realtime’s
    conduct does not amount to simply refiling; as the district
    court found, it is a misuse of the ability to refile to wipe the
    slate clean when the Delaware action was on the eve of is-
    suing a potentially adverse merits ruling, and then select a
    new forum that clashed with Realtime’s prior litigation po-
    sition.
    Accordingly, there is nothing erroneous about the con-
    clusion that Realtime “impermissibly” and “unjustifi[ably]”
    engaged in forum-shopping in attempt to avoid or delay an
    adverse ruling. Id. at *6–7. The blatant gamesmanship
    presented by the facts of this case constitutes a willful ac-
    tion for an improper purpose, tantamount to bad faith, and
    therefore within the bounds of activities sanctionable un-
    der a court’s inherent power in view of the Ninth Circuit’s
    standard. Identifying no legal error or clearly erroneous
    fact findings, we hold that the district court did not abuse
    its discretion in awarding fees pursuant to its inherent eq-
    uitable powers.
    B
    Netflix cross-appeals, arguing that the district court
    erred by declining to award fees in the related Delaware
    and inter partes review proceedings. Just as with a district
    court’s decision to award attorneys’ fees, we also review the
    district court’s decision not to award fees for abuse of dis-
    cretion and nothing obligates the district court to award
    fees in related actions. Munchkin, Inc. v. Luv n’ Care, Ltd.,

    § 285 permits recovery of attorney’s fees for parallel
    USPTO proceedings”) (emphasis added); Monolithic Power

    (Fed. Cir. 2013) (finding that the district court did not
    abuse its discretion in awarding fees for a related ITC ac-
    tion); PPG Indus., Inc. v. Celanese Polymer Specialties Co.,
    
    840 F.2d 1565
    , 1569 (Fed. Cir. 1988) (recognizing the dis-
    trict court’s “broad discretion in calculating the amount of
    fees” although reversing the trial court’s denial of fees for
    related reissue proceedings because it held that the “entire
    work product was necessary to the case”). Here, the district
    court’s fact findings support differentiating the related pro-
    ceedings.
    The district court concluded that there was no evidence
    that the initial filing of the 2017 Delaware action was “un-
    tenable.” Fees Award at *6. At that point in time, none of
    the adverse rulings had occurred and there was no indica-
    tion that “Realtime knew or should have known about the
    weakness of its claims.” Id. at *6, *9. Although the peti-
    tions for inter partes review were instituted during the pen-
    dency of the Delaware action, the district court found it did
    not have sufficient evidence to determine whether institu-
    tion alone “should have served to apprise Realtime of the
    futility of its litigation efforts.” Id. at *9. And, Realtime
    had not yet engaged in its forum-shopping ploy that formed
    the basis for a fees award in the California actions. Id.
    at *10. Accordingly, the district court declined to award
    fees for the 2017 Delaware action and the inter partes re-
    view proceedings Netflix filed in response to that action.
    Because we hold that the district court did not abuse
    its discretion in declining to award attorneys’ fees for the
    related actions, we need not address the hypothetical of
    whether such an award would be authorized under either
    § 285 or Federal Rule of Civil Procedure 41. The district
    court explicitly found that “[e]ven assuming that it is
    within [its] discretion [to award fees for the related ac-
    tions], [it] finds that such an award is not warranted here.”
    Id. at *10. We affirm the district court’s decision on that
    independent ground.

    CONCLUSION
    We have considered parties’ remaining arguments and
    do not find them persuasive. In view of the foregoing, we
    affirm the district court’s award of attorneys’ fees for both
    California actions and denial of fees for the related Dela-
    ware action and inter partes review proceedings.

    REYNA, Circuit Judge, concurring-in-part and dissenting-
    in- part.
    I concur with the majority’s holding that the district
    court did not abuse its discretion in awarding fees under
    its inherent powers to sanction. I dissent in part because I
    also believe that the district court did not err in determin-
    ing that two voluntary dismissals without prejudice is suf-
    ficient to confer prevailing party status under 
    35 U.S.C. §285
    .
    It is undisputed that at least some claims were brought
    in both the Delaware and Central District of California ac-
    tions. It is also undisputed that those claims were volun-
    tarily dismissed under Federal Rule of Civil Procedure
    Case: 21-1484    Document: 76      Page: 16    Filed: 07/27/2022

    41(a)(1)(A)(i) by Appellant in both actions. Pursuant to
    Rule 41(a)(1)(B), and as a matter of law, the second volun-
    tary dismissal operates as an adjudication on the merits.
    Such an adjudication undeniably changes the legal rela-
    tionship of the parties, even if the full scope of any result-
    ing claim preclusion is not determined until a third action
    is filed.
    The case law requiring a judicially sanctioned change
    in the relationship is in place to contrast situations in
    which the legal relationship between the parties changes
    due to circumstances independent of the judicial process,
    for example, if one party dies, or the parties reach a settle-
    ment. Here, the change in the legal relationship is by and
    through the rules of the court. And, here, the change in the
    legal relationship, i.e., an adjudication on the merits, is a
    result of judicial imprimatur. Interpreting our case law to
    require an affirmative order or act by the court puts form
    over substance. As such, I would hold that a second volun-
    tary dismissal of the same claims is sufficient to confer pre-
    vailing party status on the nonmoving party.
