    Before PROST, Chief Judge, DYK and STOLL, Circuit
    Judges.
    Opinion for the court filed by Chief Judge PROST.
    Dissenting opinion filed by Circuit Judge STOLL.
    PROST, Chief Judge.
    Nantkwest, Inc. appeals from a decision of the United
    States District Court for the Eastern District of Virginia
    granting-in-part and denying-in-part the United States
    Patent and Trademark Office (“USPTO”) Director’s mo-
    tion for fees. In its order, the district court granted the
    Director’s requested witness’ fees but denied the request-
    ed attorneys’ fees. The Director appeals the court’s denial
    of attorneys’ fees. We reverse.
    I
    In 2001, Dr. Hans Klingemann filed a patent applica-
    tion directed to a method of treating cancer by adminis-
    tering natural killer cells. After several years of
    examination, the USPTO rejected Dr. Klingemann’s
    application on obviousness grounds. The Patent and Trial
    Appeal Board (“PTAB”) affirmed the examiner’s rejection
    and Nantkwest, as assignee of the application, appealed
    to the district court under 
    35 U.S.C. § 145
    . We have
    provided a summary of the technology and the proceed-
    ings at the USPTO and district court in Nantkwest’s
    NANTKWEST, INC.   v. MATAL                                  3
    companion appeal. Nantkwest, Inc. v. Michelle K. Lee, No.
    2015-2095, slip op. at 2–5 (Fed. Cir. May 3, 2017).
    Section 145 provides that an applicant dissatisfied
    with the PTAB’s decision may appeal directly to the
    United States District Court for the Eastern District of
    Virginia in lieu of immediate appeal to this court. 
    35 U.S.C. § 145
    . The statute further provides that the appli-
    cant must pay “[a]ll of the expenses of the proceeding,”
    
    id.,
     “regardless of the outcome,” Hyatt v. Kappos, 
    625 F.3d 1320
    , 1337 (Fed. Cir. 2010) (en banc), aff’d and remanded,
    
    132 S. Ct. 1690
     (2012). After prevailing at the district
    court on the merits, the Director filed a motion to recover
    $111,696.39 of the USPTO’s fees under the § 145 expense
    provision. See J.A. 84 (seeking $78,592.50 in attorneys’
    fees (including paralegal fees) and $33,103.89 in expert
    fees). 1
    Although the district court granted the USPTO’s ex-
    pert fees, it denied its requested attorneys’ fees, citing the
    “American Rule.” J.A. 10–11. Under this Rule, litigants
    pay their own attorneys’ fees, win or lose, unless a statute
    or contract provides otherwise. Hardt v. Reliance Stand-
    ard Life Ins. Co., 
    560 U.S. 242
    , 252–53 (2010). Applying
    this Rule, the court found that in order to recover these
    fees, “[d]efendants must be able to articulate a statutory
    provision that clearly and explicitly allows them to recov-
    ery attorneys’ fees from Plaintiff.” J.A. 3–4. The district
    court concluded that the “[a]ll expenses” provision of the
    statute was neither sufficiently specific nor explicit
    enough for the authorization of attorneys’ fees under this
    1   To arrive at this value, the USPTO calculated the
    pro-rata share of the salaries of the two attorneys and one
    paralegal who worked on the appeal. J.A. 83–84.
    Nantkwest did not challenge the number of hours ex-
    pended or the pro-rata share of salaries the USPTO
    proffered at the district court. J.A. 138–40.

    Rule. 
    Id.
     On appeal, the Director argues that the district
    court erred by excluding the USPTO’s attorneys’ fees
    under § 145. We have jurisdiction under 
    28 U.S.C. § 1295
    (a)(4)(C).
    II
    The principal issue on appeal is whether § 145’s “[a]ll
    expenses of the proceedings” provision authorizes an
    award of the USPTO’s attorneys’ fees under this section. 2
    We review a district court’s interpretation of a statute
    de novo. Weatherby v. Dep’t of the Interior, 
    466 F.3d 1379
    ,
    1383 (Fed. Cir. 2006). “In construing a statute or regula-
    tion, we begin by inspecting its language for plain mean-
    ing.” Meeks v. West, 
    216 F.3d 1363
    , 1366 (Fed. Cir. 2000)
    (citation omitted). In the absence of a definition of a term,
    courts give the words their “ordinary, contemporary,
    common meaning.” Williams v. Taylor, 
    529 U.S. 420
    , 421
    (2000).
    Under 
    35 U.S.C. § 145
    ,
    [a]n applicant dissatisfied with the decision of the
    [PTAB] . . . may, unless appeal has been taken to
    the United States Court of Appeals for the Federal
    Circuit, have remedy by civil action against the
    Director in the United States District Court for
    the Eastern District of Virginia . . . . All the ex-
    penses of the proceedings shall be paid by the ap-
    plicant.
    2    Throughout its briefing, the Director routinely re-
    fers to these attorneys’ fees as “personnel expenses.” See,
    e.g., Appellant’s Br. 3. Because there is no genuine dis-
    pute that the terms “personnel expenses” and “attorneys’
    fees” are interchangeable within the context of this ap-
    peal, we refer to them as “attorneys’ fees” throughout this
    opinion.
    NANTKWEST, INC.   v. MATAL                                 5
    
    Id.
     (emphasis added).
    At the outset, we observe that we have previously
    construed other portions of § 145. See, e.g., Hyatt, 625
    F.3d at 1322. Although Hyatt resolved a different issue
    than the one presented here, we based our holding, in
    part, on our recognition of the breath of the “all expenses”
    provision and the substantial financial burden that appli-
    cants must bear for initiating § 145 appeals. Id. at 1337.
    “To deter applicants from exactly the type of procedural
    gaming that concerns the Director, Congress imposed on
    the applicant the heavy economic burden of paying ‘[a]ll
    the expenses of the proceedings’ regardless of the out-
    come.” Id. (alteration in original) (citing 
    35 U.S.C. § 145
    ).
    Put another way, Congress intended that all applicants
    unconditionally assume this financial burden when seek-
    ing review directly in district court—whether they win, or
    lose. We thus concluded that Congress drafted this provi-
    sion without requiring any degree of success on the merits
    (much less a prevailing party) as a necessary precedent
    for shifting this “heavy economic burden” onto the appli-
    cant. 
    Id.
    A
    Before determining whether § 145 authorizes an
    award of the USPTO’s attorneys’ fees, we first address the
    government’s argument that the American Rule does not
    apply to these proceedings. Like the Fourth Circuit, we
    have substantial doubts that this provision even impli-
    cates this Rule. See Shammas v. Focarino, 
    784 F.3d 219
    ,
    223 (4th Cir. 2015), cert. denied sub nom. Shammas v.
    Hirshfeld, 
    136 S. Ct. 1376
     (2016) (concluding that a
    nearly identical statutory provision governing Trademark
    appeals (
    15 U.S.C. § 1071
    (b)(3)) does not “operate[]
    against the backdrop of the American Rule” because that
    provision made no reference to prevailing parties).
    In response to the government’s arguments,
    Nantkwest relies on Baker Botts L.L.P. v. ASARCO LLC
    6                                   NANTKWEST, INC.   v. MATAL
    to support its position that the American Rule applies
    whenever a litigant seeks to recover attorneys’ fees. 
    135 S. Ct. 2158
    , 2164 (2015). 3 Baker Botts, however, does not
    stand for a general proposition that courts must apply the
    American Rule’s specific and explicit requirements to all
    fee statutes irrespective of a prevailing party as
    Nantkwest contends. Rather, it demonstrates that a
    statute must meet these requirements before a party may
    recover its fees when attempting to extend its reach to
    ancillary litigation Congress never intended. See 
    id. at 2165
    . Nevertheless, despite our doubts as to the applica-
    bility of the American Rule here, we analyze § 145’s “[a]ll
    expenses of the proceeding” provision assuming the Rule
    applies, as we conclude that even under this Rule, the
    expenses at issue here include the USPTO’s attorneys’
    fees.
    B
    Under the American Rule, “the prevailing litigant is
    ordinarily not entitled to collect a reasonable attorneys’
    fee from the loser.” Alyeska Pipeline Serv. Co. v. Wilder-
    ness Soc’y, 
    421 U.S. 240
    , 247 (1975). Courts uniformly
    recognize an exception to this general proposition, howev-
    er: when the statute itself “specific[ally]” and “explicit[ly]”
    authorizes an award of fees, the prevailing party may be
    entitled to collect its fees. 
    Id. at 260
    . In agreement with
    3   In that case, although the statute made no refer-
    ence to prevailing parties, Congress drafted the fees
    provision to apply exclusively to non-adversarial bank-
    ruptcy proceedings. 
    Id.
     at 2163–65. Nevertheless, Baker
    Botts used this provision as a basis to recover its fees for
    work it performed in a related, but adversarial, fee-
    defense litigation. Id. at 2166. By applying this statute to
    a proceeding Congress never contemplated in the first
    instance, Baker Botts effectively sought its fees in the
    absence of a fee statute altogether.
    NANTKWEST, INC.   v. MATAL                                    7
    two other circuits, we conclude that “expenses” here
    includes attorneys’ fees. See Shammas, 784 F.3d at 222–
    23 (holding that the term “expenses” covers the USPTO’s
    attorneys’ fees); United States v. 110-118 Riverside Ten-
    ants Corp., 
    886 F.2d 514
    , 520 (2d Cir. 1989) (observing
    that attorneys’ fees are “expenses of the proceedings”
    under § 6342 of the Internal Revenue Code). 4
    1
    The definitions and explanations that standard legal
    dictionaries and treatises provide for the term “expense”
    support this conclusion. Wright & Miller on Federal
    Practice and Procedure, for example, defines this term as
    “includ[ing] all the expenditures actually made by a
    litigant in connection with the action,” including “attor-
    ney’s fees.” 10 Charles Alan Wright et al., Federal Prac-
    tice and Procedure § 2666 (3d ed. 1998). Similarly, Black’s
    Law Dictionary defines “expenses” as “expenditure[s] of
    money, time, labor, or resources to accomplish a result.”
    Black’s Law Dictionary 698 (10th ed. 2014) (“Black’s”)
    (emphasis added).
    The dissent summarily dismisses these definitions,
    declaring that “they are not contemporaneous with Con-
    gress’s introduction of the word ‘expenses’ into the Patent
    Act in 1839.” Dissenting Op. 14. Relying on Nineteenth
    Century dictionaries instead, the dissent concludes that
    “the words ‘expense,’ ‘cost,’ and ‘damage’ were considered
    4     The court in Riverside relied on the statutory lan-
    guage of this section’s “expenses of the [foreclosure]
    proceedings” provision when awarding the Apartment
    Corporation its attorneys’ fees. See id. (“The attorneys’
    fees incurred . . . for selling the shares . . . are in the same
    category as expenses of foreclosure and sale proceed-
    ings . . . .”).
    8                                   NANTKWEST, INC.   v. MATAL
    synonymous around the time of the 1839 Amendments.” 5
    Id. at 6. Not so. The Patent Act of 1836 specifically distin-
    guished among these three terms. Compare Act of July 4,
    1836, ch. 357, 
    5 Stat. 117
    , § 9 (“[M]oneys received into the
    Treasury under this act shall constitute a fund for the
    payment of salaries of the officers and clerks herein
    provided for, and all other expenses of the Patent Office.”
    (emphasis added)), with id. § 14 (“[W]henever, in any
    action for damages for making, using, or selling the thing
    whereof the exclusive right is secured by any patent . . . ,
    a verdict shall be rendered . . . , it shall be in the power of
    the court to render judgment for any sum above the
    amount found by such verdict as the actual damages
    sustained . . . , not exceeding three times the amount
    thereof, according to the circumstances of the case, with
    costs.” (emphases added)). The historical statute that the
    dissent relies on simply does not support its conclusion. If
    anything, this statute lends support to the majority’s
    position by expressly characterizing the salaries of
    USPTO officers and clerks and as “expenses.” Id. § 9. The
    Supreme Court has observed the distinction between
    “expenses” and “costs” recently, providing an interpreta-
    tion that comports with the modern definitions that the
    dissent disregards.
    In Taniguchi v. Kan Pacific Saipan, Ltd., the Court
    recognized the distinction between costs and fees; deter-
    mining that the term “fees” includes “expenses borne by
    5   The dissent’s position here not only lacks support
    in the briefing, but also directly undermines the party’s
    position it purports to advance. Specifically, in arguing
    that § 145 does not include attorneys’ fees, Nantkwest
    cited the same dictionary and definitions that the dissent
    now concludes bear no relevance to the interpretation of
    this statute. See Appellee’s Br. 27–28 (relying on the 2014
    Black’s Law Dictionary definition for the term, “expense”).

    litigants for attorneys.” 
    132 S. Ct. 1997
    , 2006 (2012).
    There, the Court distinguished “expenses” from the more
    limited term “costs,” which represent only a fraction of
    expenses, relying specifically on the 1998 Wright & Miller
    treatise cited above.
    Although costs has an everyday meaning synony-
    mous with expenses, the concept of taxable costs
    . . . is more limited . . . . Taxable costs are limited
    to relatively minor, incidental expenses[;]
    . . . such items as clerk fees, court reporter fees,
    expenses for printing and witnesses, expenses for
    exemplification and copies, docket fees, and com-
    pensation of court-appointed experts. . . . Taxable
    costs are a fraction of the nontaxable expenses
    borne by litigants for attorneys, experts, consult-
    ants, and investigators.
    
    Id. at 2006
     (emphasis added) (citations and quotation
    marks omitted). The Court provided this analysis in direct
    support of its holding that resolved the breadth of taxable
    costs under 
    28 U.S.C. § 1920
    . 
    Id. at 2000, 2006
    . Notably,
    neither the dissent nor Nantkwest provide contrary
    authority where the Supreme Court has held that the
    term “expenses” categorically excludes attorneys’ fees.
    Nantkwest argues here that the term “expenses” lacks
    the requisite specificity to overcome the presumption of
    the American Rule that each party will pay its own attor-
    neys’ fees. Although Nantkwest does not deny that this
    term supplies sufficient breath to cover the USPTO’s
    attorneys’ fees, it contends that the American Rule de-
    mands more. In particular, it argues “[o]n its own, the
    term ‘expenses’ is ambiguous.” Appellee’s Br. 32. As
    support, Nantkwest relies heavily on the fact that other
    federal statutes under various titles illustrate that Con-
    gress has employed the term “expenses” to authorize
    attorneys’ fees either in addition to expenses (e.g., “ex-
    penses and attorneys’ fees), or as a component of them
    10                                NANTKWEST, INC.   v. MATAL
    (e.g., “expenses including attorneys’ fees). 6 In other
    words, the term “expenses,” Nantkwest contends, can
    either include or exclude attorneys’ fees depending on the
    statute and, thus, the term is “far from clear.” Appellee’s
    Br. 33. Reviewing the list of statutes that Nantkwest
    provides, however, we conclude that Congress made clear
    that it meant to award attorneys’ fees under the broader
    term “expenses” within the context of these particular
    proceedings.
    As noted above, the ordinary meaning as defined in
    dictionaries and the Supreme Court’s interpretation of
    this term lend significant weight to the conclusion that
    when Congress used the phrase “all expenses,” it meant to
    include attorneys’ fees. The fact that the dissent and
    Nantkwest compiled a list of statutory provisions for
    which Congress on occasion employed the term “expenses”
    to authorize attorneys’ fees in addition to expenses in
    6   Nantkwest cites approximately twenty such stat-
    utory provisions covering a wide range of areas of law
    including: bankruptcy, administrative procedure, judicial
    proceedings, and financial management. Appellee’s
    Br. 32–34. Some of these statutes list attorneys’ fees in
    addition to expenses while others list attorneys’ fees as
    part of expenses. Roughly fifty percent of those statutes
    cited do not support the Appellee’s view because they
    treat attorneys’ fees as part of expenses. 
    Id.
     The fact that
    the remaining provisions support Nantkwest’s position is
    neither reliable nor significant within the context of § 145
    proceedings. Similarly, the dissent provides its own list of
    federal statutes, more than half of which actually support
    the majority’s view as well. Dissenting Op. 7–9. Notably,
    neither the dissent nor Nantkwest provide any indication
    regarding which—if any—of these cited provisions Con-
    gress enacted prior to the Supreme Court’s creation of the
    “explicit” and “specific” criteria under the American Rule.
    NANTKWEST, INC.   v. MATAL                              11
    other contexts cannot be sufficient to dislodge the reason-
    able and ordinary meaning of this term. This is especially
    true in the context of this particular statutory provision
    where Congress explicitly authorized compensation for
    “[a]ll expenses of the proceedings.” 
    35 U.S.C. § 145
    . At
    best, these examples demonstrate that Congress will not
    confine itself to a single word or phrase when referencing
    attorneys’ fees. Yet under Nantkwest’s narrow view, a
    statute could not meet the American Rule’s heightened
    demands without using the precise words “attorneys’ fees”
    or some equivalent. For example, when asked during oral
    argument to propose other language that Congress could
    have employed to satisfy the American Rule, Nantkwest
    cited “reasonable compensation of attorneys” as the only
    alternative. 7 The dissent shares this view, stating and
    restating that the statute cannot award attorneys’ fees
    because Congress did not employ these exact words. See,
    e.g., Dissenting Op. 1–2 (“Section 145 neither mentions
    ‘attorneys’ fees’ nor reflects congressional intent to au-
    thorize them.”); 
    id. at 3
     (“The phrase ‘attorneys’ fees’ is
    not mentioned [in § 145] . . . .”).
    The Supreme Court, on the other hand, has provided
    other suitable alternatives without using any of these
    words. In Baker Botts for instance, the Court recognized
    the term “litigation costs” as one such example. 135 S. Ct.
    at 2164. Clearly, “litigation costs” does not include the
    phrase “attorneys’ fees.” Yet the dissent offers little to
    justify its conflict with the Supreme Court’s conclusion
    that the use of the term “litigation costs” overcomes the
    American Rule. While a reference to a “prevailing party”
    7    Oral Argument 12:42–13:17, http://oralarguments.
    cafc.uscourts.gov/mp3/2016-1794.mp3. We perceive no
    practical difference between “attorneys’ fees” and the
    “reasonable compensation of attorneys” example
    Nantkwest provided.
    12                                  NANTKWEST, INC.   v. MATAL
    may “usually” appear in fee-shifting statutes, id., the
    Supreme Court has never suggested that such a reference
    is a requirement for fee shifting, contrary to what the
    dissent argues. See Dissenting Op. 9–10 (“Nothing in
    [§ 145] confines the award of expenses to a prevailing
    party.”).
    The law neither confines Congress to the use of any
    particular term or phrase to satisfy the American Rule’s
    specificity requirement nor requires that Congress employ
    the words, “compensation,” “fee,” or “attorney” to meet it.
    The term “expenses,” like “litigation costs,” is another
    example where Congress authorized fee awards without
    including the words “fees” or “compensation” in the stat-
    ute. Nantkwest and the dissent simply demand too much.
    Our conclusion that this term authorizes the USPTO’s
    fee award is particularly important here in the context of
    § 145’s all expenses provision. This unique provision
    requires that applicants uniformly name the Director as
    defendant to their suits. In representing the USPTO’s
    interests, the Director relies on personnel from the Office
    of the Solicitor. See 
    37 C.F.R. § 11.40
    (b). These attor-
    neys—the Solicitor, his deputy, and associates—and
    supporting paralegals receive fixed salaries as compensa-
    tion for their government work. As salaried employees,
    they do not bill individual hours for their work, nor do
    they collect fees from those whom they represent. In this
    context, we characterize the overhead associated with
    their work more precisely as an “expense” to the govern-
    ment than a “fee.” Compare Black’s 698 (defining “ex-
    pense” as “expenditure[s] of money, time, labor, or
    resources to accomplish a result”), with Black’s 154 (defin-
    ing “attorney’s fee” as “[t]he charge to a client for services
    performed for the client, such as an hourly fee, a flat fee,
    or a contingent fee”). Under the dissent and Nantkwest’s
    view, Congress must use the word “fee” instead for the
    USPTO to receive remuneration. We do not view the
    American Rule so narrowly. To conclude otherwise, our
    NANTKWEST, INC.   v. MATAL                              13
    interpretation would force Congress into the untenable
    position of selecting a word that must be applied in an
    unconventional and imprecise manner in the context of
    these unique proceedings. 8
    Given the Supreme Court’s construction of “expenses,”
    the guidance dictionary and treatises provide on this
    term, and the context in which Congress applied it, we
    conclude that the term “expenses” includes the USPTO’s
    attorneys’ fees under § 145.
    2
    Nantkwest makes an additional argument regarding
    whether the USPTO’s attorneys’ fees are “expenses of the
    proceedings.” 
    35 U.S.C. § 145
    . It contends that this provi-
    sion does not provide a basis for attorneys’ fees because
    8    Congress’s contrasting use of the term “attorneys’
    fees” under 
    35 U.S.C. § 285
     provides further evidence to
    this point. There, Congress chose not to award all expens-
    es to the prevailing party, but only attorneys’ fees. The
    dissent appears to ignore this distinction, instead requir-
    ing that Congress recite the phrase “attorneys’ fees” to
    cover at least a subset of these “expenses” simply because
    other portions of Title 35 employ that phrase. Dissenting
    Op. 4–5. Put another way, under the dissent’s view,
    Congress must rigidly employ a phrase such as “attor-
    neys’ fees and other expenses” in place of the broader
    term “expenses,” which already includes these fees. Rely-
    ing on a flawed premise, the dissent simply dismisses—
    even as a theory—that Congress could have intended a
    broader compensation scheme under § 145 than § 285.
    Congress indisputably has the authority to employ a
    broad word over other narrower alternatives if it so
    chooses. And it may do so irrespective of how many times
    it amended other portions of Title 35 or employed narrow-
    er alternatives for other sections of the Code.
    14                                 NANTKWEST, INC.   v. MATAL
    the USPTO would have had to pay the portions of these
    full-time employees’ salaries regardless of Nantkwest’s
    suit.
    We disagree. First, we have accorded similar relief in
    the past in the context of other salaried attorneys. In
    Raney v. Federal Bureau of Prisons, for example, we
    awarded salaried union attorneys an apportionment of
    their salaries because the litigation required the lawyers
    to divert their time away from other pending matters. 
    222 F.3d 927
    , 935 (Fed. Cir. 2000). Second, our sister circuits
    have recognized the costs associated with these diversions
    and awarded fees to salaried employees as well. See, e.g.,
    Shammas, 784 F.3d at 223 (recognizing that the USPTO
    “incurred expenses when its attorneys were required to
    defend the Director in the district court proceedings,
    because their engagement diverted the PTO’s resources
    from other endeavors”); Wisconsin v. Hotline Indus., Inc.,
    
    236 F.3d 363
    , 365–66 (7th Cir. 2000) (holding that sala-
    ried government employees could recover their fees as
    they relate to the government’s opposition to an improper
    removal of a state court case).
    Section 145 proceedings similarly impact the
    USPTO’s resources. These costs are particularly relevant
    here, where the USPTO attributes over seventy percent of
    its total expenses ($78,592.50 of the $111,696.39) to
    attorneys’ fees. Nantkwest filed its appeal in district court
    and enjoyed the pro-applicant benefits of that forum. See
    Hyatt, 625 F.3d at 1336–37 (obtaining de novo review
    with the ability to introduce new evidence). Under
    Nantkwest’s view, the government’s recovery would be
    limited only to certain ad hoc expenses, e.g., printing,
    travel, expert witness costs, Appellee’s Br. 35, while
    ignoring the vast majority of the expenses the USPTO
    incurred as the proximate cause of Nantkwest’s appeal.
    We cannot subscribe to this view.
    NANTKWEST, INC.   v. MATAL                               15
    It cannot be credibly disputed that the USPTO dedi-
    cated time and resources of its attorneys to the defense of
    this litigation when it could have otherwise applied those
    resources to other matters. Without acknowledging these
    concerns, Nantkwest essentially endorses a rule that
    would theoretically permit an award if the USPTO re-
    tained outside counsel to defend its interests but not if it
    elected to proceed on its own. Logically, the meaning of “of
    the proceedings” cannot turn on the type of attorneys
    retained to defend the government’s interests. As we
    previously observed, we must equally regard salaried
    attorneys’ time and “tak[e] into account the opportunity
    costs involved in devoting attorney time to one case when
    it could be devoted to others.” Raney, 
    222 F.3d at
    934–35. 9
    We thus conclude that § 145 entitles the USPTO to com-
    pensation for the diversion of its resources in the defense
    of § 145 appeals.
    Accordingly, we hold that “[a]ll expenses of the pro-
    ceedings” under § 145 includes the pro-rata share of the
    attorneys’ fees the USPTO incurred to defend applicant’s
    appeal. To conclude otherwise would conflict with Hyatt,
    where we recognized the “heavy economic burden” that
    § 145 shifts onto applicants for electing this favorable
    appellate path. Hyatt, 625 F.3d at 1337.
    We have considered Nantkwest’s remaining argu-
    ments in this appeal but find them unpersuasive as well.
    9    Without shouldering these expenses itself,
    Nantkwest seeks a ruling that essentially requires other
    applicants to fund its own appeal. See Leahy-Smith
    America Invents Act, Pub. L. No. 112-29, § 10, 
    125 Stat. 284
    , 316 (2011) (recognizing the USPTO as exclusively an
    applicant-funded agency). Although this may be appropri-
    ate in the context of other agency proceedings, it does not
    accord with our requirement that the applicant itself must
    bear the burden of these appeals. Hyatt, 625 F.3d at 1337.

    CONCLUSION
    For the foregoing reasons, we reverse the district
    court and remand the case for it to enter an additional

    STOLL, Circuit Judge, dissenting.
    Under the American Rule, “each party in a lawsuit
    ordinarily shall bear its own attorney’s fees unless there
    is express statutory authorization to the contrary.”
    Hensley v. Eckerhart, 
    461 U.S. 424
    , 429 (1983). It erects a
    strong presumption against fee-shifting, requiring an
    explicit provision permitting a departure from the Ameri-
    can Rule or other evidence of congressional intent to make
    such an award available. Section 145 neither mentions
    “attorneys’ fees” nor reflects a congressional intent to
    2                                 NANTKWEST, INC.   v. MATAL
    authorize them. Because I believe § 145 fails to provide
    the necessary congressional directive to overcome the
    American Rule’s bar against shifting attorneys’ fees, I
    respectfully dissent.
    I.
    The majority expresses “substantial doubts” regarding
    whether the American Rule applies to § 145. Maj. Op. 5.
    But Supreme Court precedent makes clear that the Amer-
    ican Rule marks the starting point for any analysis that
    shifts fees from one litigant to another. Often referred to
    as a “bedrock principle,” the American Rule requires that
    “[e]ach litigant pay[] his own attorney’s fees, win or lose,
    unless a statute or contract provides otherwise.” Baker
    Botts L.L.P. v. ASARCO LLC, 
    135 S. Ct. 2158
    , 2164
    (2015) (quoting Hardt v. Reliance Standard Life Ins. Co.,
    
    560 U.S. 242
    , 253 (2010)). This presumption against fee
    shifting in American litigation dates back more than 200
    years to Arcambel v. Wiseman, 3 U.S. (3 Dall.) 306 (1796).
    “[T]he law of the United States, but for a few well-
    recognized exceptions not present [here], has always been
    that absent explicit congressional authorization, attor-
    neys’ fees are not a recoverable cost of litigation.” Runyon
    v. McCrary, 
    427 U.S. 160
    , 185 (1976) (footnote omitted).
    While Congress remains free to draft statutes provid-
    ing for the award of attorneys’ fees, any such deviation
    from the American Rule must be “specific and explicit,”
    for Congress has not “extended any roving authority to
    the Judiciary to allow counsel fees as costs or otherwise
    whenever the courts might deem them warranted.”
    Alyeska Pipeline Serv. Co. v. Wilderness Soc’y, 
    421 U.S. 240
    , 260–62 (1975) (citing statutory provisions containing
    the phrase “attorney’s fees” as examples of “specific and
    explicit provisions for the allowance of attorneys’ fees”).
    Several cases have recognized that a statute’s failure to
    reference “attorneys’ fees” is not always dispositive, but
    the statute must “otherwise evince[] an intent to provide
    NANTKWEST, INC.   v. MATAL                                 3
    for such fees.” See, e.g., Key Tronic Corp. v. United States,
    
    511 U.S. 809
    , 815 (1994). This necessitates resort to the
    ordinary meaning of the phrase that is alleged to shift
    attorneys’ fees and the legislative history of the statutory
    provision to see if such an intent exists.

     at 817–19;
    Summit Valley Indus. Inc. v. Local 112, United Bhd. of
    Carpenters & Joiners of Am., 
    456 U.S. 717
    , 722–23 (1982).
    II.
    It is against this backdrop that we analyze whether
    Congress expressed an intent “to set aside this longstand-
    ing American rule of law,” Runyon, 
    427 U.S. at
    185–86,
    and award attorneys’ fees under § 145. In order to shift
    the PTO’s attorneys’ fees to NantKwest in this case, we
    must find in the text of § 145 a “specific and explicit”
    authorization from Congress.       See Alyeska Pipeline,
    
    421 U.S. at 260
    . Without express authority, the ordinary
    meaning of “expenses” or § 145’s legislative history has to
    provide it. A searching review exposes no such authoriza-
    tion.
    A.
    The language of § 145 does not explicitly grant us au-
    thority to shift attorneys’ fees. Section 145 requires a
    patent applicant electing to challenge the PTO’s unfavor-
    able decision in district court to pay “[a]ll the expenses of
    the proceedings.” 
    35 U.S.C. § 145
     (emphasis added). The
    phrase “attorneys’ fees” is not mentioned, and Congress’s
    use of “expenses” is not the type of “specific and explicit”
    language that permits the award of attorneys’ fees. See
    Summit Valley, 
    456 U.S. at 722
     (noting that statute does
    not expressly mention attorneys’ fees); Key Tronic,
    
    511 U.S. at
    814–15 (same); F. D. Rich Co. v. U.S. for the
    Use of Indus. Lumber Co., 
    417 U.S. 116
    , 126 (1974)
    (same).
    In this case, the omission of “attorneys’ fees” from
    § 145 is particularly telling. When Congress wanted to
    4                                 NANTKWEST, INC.   v. MATAL
    make attorneys’ fees available in a patent litigation, it
    knew how to do so. Section 285 of the America Invents
    Act, for example, provides: “The court in exceptional cases
    may award reasonable attorney fees to the prevailing
    party.” 
    35 U.S.C. § 285
     (emphasis added). Several other
    sections of the Patent Act cross-reference § 285, and each
    of those sections recognizes the availability of “attorney
    fees” under § 285. See, e.g., id. § 271(e)(4); § 273(f).
    Similarly, Section 297 of the AIA permits a customer who
    has been defrauded by an invention promoter to recover
    “reasonable costs and attorneys’ fees,” in addition to other
    damages incurred by the customer. Id. § 297(b)(1) (em-
    phasis added).
    It is a fundamental principle of statutory interpreta-
    tion that, “[w]here Congress includes particular language
    in one section of a statute but omits it in another section
    of the same Act, it is generally presumed that Congress
    acts intentionally and purposely in the disparate inclu-
    sion or exclusion.” Russello v. United States, 
    464 U.S. 16
    ,
    23 (1983) (quoting United States v. Wong Kim Bo,
    
    472 F.2d 720
    , 722 (5th Cir. 1972)). Congress decided to
    exclude “attorney fees” from § 145 but not § 285—the
    exact type of disparate exclusion we ordinarily presume to
    be intentional. 1 The omission of attorneys’ fees from
    1   Congress has expressly awarded attorneys’ fees in
    many other statutory contexts. See, e.g., 
    7 U.S.C. § 2565
    (“The court in exceptional cases may award reasonable
    attorney fees to the prevailing party.”); 
    10 U.S.C. § 1089
    (f)(2) (recognizing that statute provides “the au-
    thority to provide for reasonable attorney’s fees”);
    
    15 U.S.C. § 1117
    (a) (permitting award of “reasonable
    attorney fees to the prevailing party” for certain trade-
    mark violations); 22 U.S.C. § 277d-21 (permitting Com-
    missioner to “allow reasonable attorneys’ fees”); 42 U.S.C.
    NANTKWEST, INC.   v. MATAL                                  5
    § 145 “strongly suggest[s] a deliberate decision not to
    authorize such awards.” Key Tronic, 
    511 U.S. at
    818–19.
    It reveals Congress’s intent “to pick and choose among its
    statutes and to allow attorneys’ fees under some, but not
    others.” Alyeska Pipeline, 
    421 U.S. at 263
    .
    Congress’s knowledge of the American Rule lends
    even more force to this argument. At least as early as
    1973, Congress formed subcommittees to study attorneys’
    fees and other issues affecting legal services. See F. D.
    Rich Co., 
    417 U.S. at
    131 & n.20. And when warranted,
    Congress has drafted statutes to overcome the American
    Rule. See Hensley, 
    461 U.S. at 429
     (stating that Congress
    enacted Civil Rights Attorney’s Fees Awards Act of 1976
    in response to American Rule to provide explicit authori-
    zation for shifting attorneys’ fees). As it did with the Civil
    Rights Attorney’s Fees Awards Act of 1976, Congress
    could have revised § 145 to expressly provide for the
    award of attorneys’ fees. Congress, however, did not. We
    should defer to Congress’s decision. See Gross v. FBL Fin.
    Servs., Inc., 
    557 U.S. 167
    , 174 (2009) (“When Congress
    amends one statutory provision but not another, it is
    presumed to have acted intentionally.”).
    B.
    Because § 145 lacks specific and explicit statutory au-
    thority to shift attorneys’ fees, we must be able to glean a
    congressional intent to do so from the ordinary meaning of
    “expenses” or the legislative history of § 145. The majori-
    § 2000e-16c(e) (stating “attorney’s fees may be allowed by
    the court”); 
    46 U.S.C. § 41305
    (e) (“[T]he prevailing party
    may be awarded reasonable attorney fees.”).
    6                                 NANTKWEST, INC.   v. MATAL
    ty concludes that the ordinary meaning of “expenses”
    necessarily includes attorneys’ fees. 2 I disagree.
    It is a fundamental canon of statutory construction
    that, “‘[u]nless otherwise defined, words will be interpret-
    ed as taking their ordinary, contemporary, common
    meaning’ at the time Congress enacted the statute.”
    Amoco Prod. Co. v. S. Ute Indian Tribe, 
    526 U.S. 865
    ,
    873–74 (1999) (quoting Perrin v. United States, 
    444 U.S. 37
    , 42 (1979)). As the Director points out in her brief,
    Congress amended the Patent Act in 1839 to require that
    “the whole of the expenses of the proceeding shall be paid
    by the applicant, whether the final decision shall be in his
    favor or otherwise.” Act of Mar. 3, 1839, ch. 88, § 10,
    
    5 Stat. 353
    , 354; Appellant Br. 21. In the 1830s, the
    definition of “expense” included “cost,” and the definition
    of “cost” included “expense.” J.E. Worcester, A Pronounc-
    ing and Explanatory Dictionary of the English Language
    with Pronouncing Vocabularies of Classical and Scripture
    Proper Names 75, 117 (1830); see also Noah Webster et
    al., An American Dictionary of the English Language 197,
    319 (Joseph Emerson ed., 1830) (listing definition for
    “expense” as “cost” and vice versa). Moreover, the words
    “expense,” “cost,” and “damage” were considered synony-
    mous around the time of the 1839 Amendments. Peter
    Mark Roget, Thesaurus of English Words and Phrases 227
    (Barnas Sears ed., 1856).
    These definitions suggest that, at the time Congress
    introduced the word “expenses” into the Patent Act, its
    ordinary meaning did not include attorneys’ fees. The
    Supreme Court has twice held that the word “damages”—
    a synonym for “expenses” at the time of enactment—is
    insufficient to override the American Rule. See Summit
    2   The majority does not rely on the legislative histo-
    ry to support its position.
    NANTKWEST, INC.   v. MATAL                                7
    Valley, 
    456 U.S. at
    722–23 (“Ordinarily a statutory right
    to ‘damages’ does not include an implicit authorization to
    award attorney’s fees. Indeed, the American Rule pre-
    sumes that the word ‘damages’ means damages exclusive
    of fees.” (emphasis added)); Arcambel, 3 U.S. (3 Dall.) at
    306. And even the majority agrees that the word “costs”
    cannot displace the American Rule. See Maj. Op. 8–9.
    There can be no doubt that the ordinary meaning of
    “expenses” at the time of its inclusion in the Patent Act
    falls short of overcoming the American Rule. That the
    PTO did not rely on this provision to seek attorneys’ fees
    for over 170 years supports the understanding that it is
    far from clear whether “[a]ll the expenses of the proceed-
    ings” includes attorneys’ fees.
    Congress’s frequent use of “expenses” and “attorneys’
    fees” in other statutory provisions further reinforces that
    “[a]ll the expenses of the proceedings” does not necessarily
    include attorneys’ fees. The U.S. Code is replete with
    examples of Congress awarding “expenses” and then
    separately clarifying that attorneys’ fees are also availa-
    ble. See, e.g., 
    11 U.S.C. § 363
    (n) (authorizing trustee to
    recover “any costs, attorneys’ fees, or expenses incurred”
    in certain situations);

    and proper . . . .”);

    expenses (including the attorney’s fees) . . . shall be as-
    sessed . . . .”); 
    38 U.S.C. § 4323
    (h)(2) (“[T]he court may
    award any such person who prevails in such action or
    proceeding reasonable attorney fees, expert witness fees,
    and other litigation expenses.”); 
    41 U.S.C. § 4705
    (d)(1)(C)
    (noting that head of agency may “[o]rder the contractor to
    pay the complainant an amount equal to the aggregate
    amount of all costs and expenses (including attorneys’

    ting party to recover “reasonable expenses incurred . . .
    including a reasonable attorney’s fee”).
    The message is clear: Congress did not view “[a]ll the
    expenses of the proceedings” as necessarily including
    “attorneys’ fees.” If “expenses” included “attorneys’ fees,”
    there would be no reason for Congress to specify the
    availability of attorneys’ fees in statutes that already
    provide for the award of expenses. Instead, the logical
    implication is that “expenses” and “attorneys’ fees” mean
    different things and that expenses do not necessarily
    include attorneys’ fees. At best, Congress’s reference to
    “[a]ll the expenses” is ambiguous. As such, Congress’s
    intent is not clear, and the statutory language does not
    overcome the American Rule.
    Although Congress has enacted statutes that award
    the government attorneys’ fees in a district court action,
    in each circumstance, Congress explicitly referred to
    attorneys’ fees, making its fee-shifting intent abundantly
    clear. For example, in the context of an agency enforce-
    ment action for assessment of a civil penalty, 
    42 U.S.C. § 7413
    (a)(5)(B) provides that “[a]ny person who fails to
    pay on a timely basis a civil penalty ordered or assessed
    under this section shall be required to pay . . . the United
    States enforcement expenses, including but not limited to
    attorneys fees.”     Likewise, 
    33 U.S.C. § 1319
    (g)(9)(B)
    provides that “[a]ny person who fails to pay on a timely
    basis the amount of an assessment of a civil penalty . . .
    shall be required to pay [the agency] . . . attorneys fees
    and costs for collection proceedings.” Unlike these stat-
    utes, Congress’s alleged intent to award attorneys’ fees to
    the government in § 145 actions is not so clear.
    Finally, if § 145 were a fee-shifting statute, it would
    represent a particularly unusual divergence from the
    American Rule because it obligates even successful plain-
    tiffs to pay the PTO’s attorneys’ fees. “[W]hen Congress
    has chosen to depart from the American rule by statute,
    10                                   NANTKWEST, INC.   v. MATAL
    virtually every one of the more than 150 existing federal
    fee-shifting provisions predicates fee awards on some
    success by the claimant.” Ruckelshaus v. Sierra Club,
    
    463 U.S. 680
    , 684 (1983); see also Baker Botts, 135 S. Ct.
    at 2164 (recognizing deviations from American Rule “tend
    to authorize the award of ‘a reasonable attorney’s fee,’
    ‘fees,’ or ‘litigation costs,’ and usually refer to a ‘prevailing
    party’ in the context of an adversarial ‘action.’”). Nothing
    in § 145 confines the award of expenses to a prevailing
    party. Instead, it requires the applicant to pay “[a]ll the
    expenses of the proceedings,” which according to the
    majority means the applicant pays for the PTO’s attor-
    neys’ fees in every § 145 proceeding. In these atypical
    circumstances, I think Congress’s intent to award the
    PTO attorneys’ fees in every case should have been more
    clear. I cannot agree that Congress used the word “ex-
    penses” to effect such an unusual departure from the
    American Rule—a departure that would saddle even
    prevailing applicants with the PTO’s attorneys’ fees. 3
    C.
    The maintenance of a robust American Rule also finds
    support in public policy. For example, uncertainty is
    inherent in any litigation, and “one should not be penal-
    ized for merely defending or prosecuting a lawsuit,” as
    3  The majority repeatedly mischaracterizes the dis-
    sent as advocating for a rigid requirement that would bar
    the award of attorneys’ fees unless Congress invoked
    those exact words. See Maj. Op. 11, 12, 13 n.8. This is
    incorrect. My opinion only addresses whether the word
    “expenses” is a specific and explicit directive from Con-
    gress to shift attorneys’ fees or whether § 145 otherwise
    signals Congress’s intent to make an award of attorneys’
    fees available. I express no opinion as to what other
    words carry enough weight to displace the American Rule.
    NANTKWEST, INC.   v. MATAL                                11
    this could have a disproportionate effect in discouraging
    less wealthy individuals “from instituting actions to
    vindicate their rights if the penalty for losing included the
    fees of their opponents’ counsel.” Fleischmann Distilling
    Corp. v. Maier Brewing Co., 
    386 U.S. 714
    , 718 (1967); see
    also Summit Valley, 
    456 U.S. at 725
     (“[C]onsiderations
    [favoring application of the American Rule] include the
    possible deterrent effect that fee shifting would have on
    poor litigants with meritorious claims.”). Independent
    advocacy could also be threatened, the Supreme Court
    warned, “by having the earnings of the attorney flow from
    the pen of the judge before whom he argues.” F. D. Rich
    Co., 
    417 U.S. at 129
    . Finally, if the word “expenses” in
    every statute or contract trumped the American Rule,
    then “the time, expense, and difficulties of proof inherent
    in litigating the question of what constitutes reasonable
    attorney’s fees would pose substantial burdens for judicial
    administration.” Fleischmann, 
    386 U.S. at 718
    .
    Here, the majority’s interpretation would compel any
    prospective patentee who avails herself of the review
    afforded by § 145 to pay the PTO’s attorneys’ fees even if
    the applicant prevails and proves error by the PTO. 4
    These high and uncertain costs will likely deter appli-
    cants, particularly solo inventors and other smaller enti-
    ties, from pursuing review under § 145. And every § 145
    4   The AIA offers two options for judicial review of a
    Board decision rejecting a patent application. The appli-
    cant can appeal to the Federal Circuit under § 141 or it
    can file a civil action in the Eastern District of Virginia
    against the Director of the PTO under § 145. See Kappos
    v. Hyatt, 
    132 S. Ct. 1690
    , 1694 (2012). Seeking review
    under § 145 offers certain benefits to the applicant, in-
    cluding the ability to conduct discovery and introduce
    additional evidence. See id. at 1700–01.
    12                                 NANTKWEST, INC.   v. MATAL
    proceeding would involve litigation over whether the
    PTO’s attorneys’ fees were reasonable, creating an addi-
    tional burden for the district court. I am not convinced
    that Congress intended such an outcome.
    III.
    The majority’s arguments to the contrary do not per-
    suade me to conclude otherwise. The majority relies
    heavily on our statement in Hyatt v. Kappos, 
    625 F.3d 1320
    , 1337 (Fed. Cir. 2010) that plaintiffs who proceed
    under § 145 bear “the heavy economic burden of paying
    ‘[a]ll the expenses of the proceedings’ regardless of out-
    come.” Maj. Op. 5, 15. This observation, however, does
    not require that expenses include attorneys’ fees. Indeed,
    the PTO has traditionally interpreted this statutory
    language to include expert fees, court reporter fees, depo-
    sition travel expenses, and printing expenses—all of
    which can be significant and pose a “heavy economic
    burden” in district court litigation.
    The majority also claims that its holding is consistent
    with opinions from the Second and Fourth Circuits that
    have interpreted “expenses” to include attorneys’ fees.
    But the rationale adopted by the majority diverges from
    that of the Fourth Circuit in Shammas v. Focarino,
    
    784 F.3d 219
     (4th Cir. 2015), and the Second Circuit’s
    opinion in United States v. 110-118 Riverside Tenants
    Corp., 
    886 F.2d 514
     (2d Cir. 1989) is easily distinguished. 5
    5  In addition, the majority cites to dicta in Tanigu-
    chi v. Kan Pacific Saipan, Ltd., 
    132 S. Ct. 1997
     (2012) as
    evidence that the Supreme Court has blessed its interpre-
    tation of “expenses.” As described by the Court, the
    question presented in Taniguchi was whether the phrase
    “compensation of interpreters” includes the cost of trans-
    lating written documents. The Court answered this
    NANTKWEST, INC.   v. MATAL                               13
    In interpreting a section of the Lanham Act requiring
    the party bringing the case to pay “all the expenses of the
    proceeding,” 
    15 U.S.C. § 1071
    (b)(3), the Shammas majori-
    ty 6 found the American Rule did not apply. Shammas,
    784 F.3d at 223. Only after dispatching with the strong
    presumption against fee shifting embodied in the Ameri-
    can Rule—a rule that the majority here assumes is appli-
    cable—was the Shammas court able to interpret the
    ordinary meaning of “expenses” to cover attorneys’ fees.
    Id. at 224. Simply reaching the same result, however,
    does not make the majority’s opinion consistent with
    Shammas. This is particularly so here because the two
    opinions offer conflicting views on the applicability of the
    foundational common law principle embodied in the
    American Rule.
    The Second Circuit’s decision in 110-118 Riverside is
    inapposite because it does not address the interpretation
    of “expenses” in a contract or statutory provision. In-
    question by concluding that “both the ordinary and tech-
    nical meanings of ‘interpreter,’ as well as the statutory
    context in which the word is found, lead to the conclusion
    that § 1920(6) does not apply to translators of written
    materials.” Id. at 2005. Only then did the Court explain
    that its holding was consistent with the “narrow scope of
    taxable costs,” which it characterized as a fraction of the
    nontaxable expenses. Id. at 2006. It never interpreted a
    statutory provision containing the word “expenses” to
    include attorneys’ fees.
    6   Judge King dissented. In his view, the American
    Rule controls the analysis, and attorneys’ fees should not
    be shifted because the statutory provision at issue “makes
    no reference to attorney’s fees awards and does not reflect
    a Congressional intention to authorize such awards.”
    Shammas, 784 F.3d at 227 (King, J., dissenting).
    14                                NANTKWEST, INC.   v. MATAL
    stead, 110-118 Riverside dealt with an apartment corpo-
    ration that incurred expenses in foreclosing a lien that the
    government placed on one of the apartment corporation’s
    tenants. The government bore responsibility for foreclos-
    ing the tax lien, but the apartment corporation effectuat-
    ed the foreclosure and shouldered the expenses associated
    with the proceeding. Because it was the government’s
    duty to foreclose the tax lien, the court found no reason
    why the government should not reimburse the apartment
    corporation for the expenses of the foreclosure proceeding,
    including attorneys’ fees. 110-118 Riverside, 
    886 F.2d at 520
    . As these facts demonstrate, 110-118 Riverside is a
    case where a private party performed the legal obligations
    of the government and was made whole for its efforts; it
    does not involve the interpretation of a statute in the
    context of adversarial litigation to determine whether
    Congress specifically and explicitly provided for the
    recovery of attorneys’ fees by one party against the other
    based on its use of the word “expenses.”
    Next, the majority relies on dictionary definitions to
    illuminate the ordinary meaning of “expenses.” The
    majority’s dictionaries, however, are from 1998 and
    2014—they are not contemporaneous with Congress’s
    introduction of the word “expenses” into the Patent Act in
    1839. Therefore, they shed no light on the ordinary
    meaning of “expenses” more than 175 years ago. See
    Amoco Prod. Co., 
    526 U.S. at
    873–74 (“‘[U]nless otherwise
    defined, words will be interpreted as taking their ordi-
    nary, contemporary, common meaning’ at the time Con-
    gress enacted the statute.” (alteration in original)
    (emphasis added) (quoting Perrin, 
    444 U.S. at 42
    )). And
    unlike the 1998 definition from Wright and Miller, the
    contemporaneous definitions do not mention “attorneys’
    fees.” See Section II.B, supra.
    Finally, the majority posits that the litany of statuto-
    ry provisions separately specifying both “expenses” and
    “attorneys’ fees” demonstrates Congress’s desire not to be
    NANTKWEST, INC.   v. MATAL                               15
    restricted to a single word or phrase when awarding
    attorneys’ fees. See Maj. Op. 11. These statutes, in my
    view, compel the opposite conclusion, especially when
    read in light of the American Rule. As explained above,
    there would be no reason for Congress to provide for the
    award of “attorneys’ fees” in numerous statutory provi-
    sions where it also permits the award of expenses if the
    contemporaneous, ordinary, and well-known meaning of
    “expenses” necessarily included attorneys’ fees. Rather,
    in the context of § 145, the term “expenses” is ambiguous
    and shows no clear intent to award attorneys’ fees.
    IV.
    The American Rule is the starting point for our anal-
    ysis, and it imposes a high bar for any litigant seeking to
    shift its attorneys’ fees to the opposing party. Despite
    assuming the American Rule’s applicability to this case,
    the majority believes § 145 provides the requisite authori-
    zation. But § 145 lacks the specific and explicit provision
    for the allowance of attorneys’ fees, and the ordinary
    meaning of “expenses” fails to fill the void. I respectfully
    dissent.
