    WYNN, Circuit Judge:
    In    April     2014,     the   U.S.       Food   and   Drug   Administration
    (“FDA”) issued a letter decision regarding the rights of patent
    holders and the ease with which generic drugs could enter the
    market place under the Hatch-Waxman Act.                        Though disclaiming
    that it was adjudicating the rights of any specific parties,
    this         letter       effectively             prevents     Appellants        Mylan
    Pharmaceuticals,         Inc.,     Watson     Laboratories,       Inc.,    and   Lupin
    Pharmaceuticals, Inc. from bringing their generic versions of
    celecoxib, an arthritis treatment drug currently sold under the
    brand name Celebrex, to the market until June 2015.                          The FDA
    based its decision on its interpretation of a Hatch-Waxman Act
    provision it deemed ambiguous.                    However, as explained below, we
    find        the   pertinent        provision          unambiguous     in    context.
    Accordingly, we reverse the district court’s opinion upholding
    the FDA’s letter decision.
    I.
    In 1984, Congress amended the Food, Drug, and Cosmetic Act
    to “make available more low cost generic drugs by establishing a
    generic drug approval procedure for pioneer drugs first approved
    after 1962.”          H.R. Rep. No. 98-857, part 1, at 14.             See The Drug
    Price Competition and Patent Term Restoration Act of 1984 (the
    “Hatch-Waxman Act” or “Hatch-Waxman”), Pub. L. No. 98-417, 98
    
    4 Stat. 1585
     (1984), formerly codified at 
    21 U.S.C. § 355
     and 
    35 U.S.C. §§ 156
    , 271, 282.                  In furtherance of this goal, the
    Hatch-Waxman       Act     created    a    truncated         approval       process     for
    generic drugs and, crucially for this case, the potential for a
    180-day period of market exclusivity for the first company to
    bring     its     generic     drugs       to       market.         The     statute,    and
    specifically the language at issue in this case, has since been
    amended      by    the     Medicare   Prescription           Drug     Improvement      and
    Modernization Act, Pub L. No. 108-173, 
    117 Stat. 2066
     (2003).
    Because the initial Abbreviated New Drug Applications at issue
    in this case were filed prior to the enactment of this revision,
    the pre-amendment version of the statute applies.
    Before marketing a new drug, a drug company must submit a
    New   Drug    Application,      an    elaborate        document      detailing,       among
    other things, the drug’s safety and efficacy.                            See 
    21 U.S.C. § 355
    (b)(1).        A New Drug Application also must contain “the patent
    number and the expiration date of any patent which claims the
    drug . . . or which claims a method of using such drug[.]”                              
    Id.
    The FDA publishes information about those patents and methods of
    use “in a fat, brightly hued volume called the Orange Book[.]”
    Caraco Pharm. Labs., Ltd. v. Novo Nordisk A/S, 
    132 S. Ct. 1670
    ,
    1676 (2012).
    Generic    drug     companies,     by       contrast,      need    not   submit   a
    complete New        Drug    Application        to    seek    FDA   approval      of   their
    5
    drugs.      Under Hatch-Waxman, they may instead file an Abbreviated
    New Drug Application, in which they may “rely on the clinical
    studies performed by the pioneer drug manufacturer” instead of
    having “to prove the safety and effectiveness of [their] generic
    drug from scratch.”              aaiPharma, Inc. v. Thompson, 
    296 F.3d 227
    ,
    231 (4th Cir. 2002).               “[T]he generic manufacturer must prove
    only that its drug is bioequivalent to the brand name drug it
    wants to copy.”          
    Id.
    In its Abbreviated New Drug Application, a generic drug
    company must make one of four certifications regarding the non-
    infringement of “listed” patents referenced in the Orange Book.
    See   
    21 U.S.C. § 355
    (j)(2)(A)(vii).                   With        the     fourth
    certification        option       (a    “Paragraph         IV    certification”),               the
    relevant one for this case, generic drug makers confirm that any
    patent for the pioneer drug is invalid or will not be infringed.
    
    Id.
            Additionally,          the     Abbreviated           New     Drug       Application
    applicant must also certify to “later-listed patents” when they
    are published in the Orange Book.                   
    Id.
     § 355(j)(2)(B).
    If,    as     in    this    case,    a       generic      drug       company       makes   a
    Paragraph     IV     certification,         it      must     provide        notice        of    its
    Abbreviated       New     Drug    Application        to    the   owner        of    any   patent
    covered by the Paragraph IV certification and to the brand-name
    company      that        filed    the     New       Drug     Application.                 Id.     §
    355(j)(2)(B)(i).                 Hatch-Waxman          treats          a      Paragraph          IV
    6
    certification as an artificial act of patent infringement by the
    generic drug company.                 Id. §§ 355(j)(2)(B)(i)-(ii); Eli Lilly &
    Co. v. Medtronic, Inc., 
    496 U.S. 661
    , 678 (1990).                                    If the brand-
    name   company        wants      to     defend      its      patent,       it       must    bring   an
    infringement          action     within          forty-five        days        of   receiving       the
    generic company’s notice.                   
    21 U.S.C. § 355
    (j)(5)(B)(iii).
    In   general,         the      FDA    “shall       approve         or    disapprove”         the
    generic     drug       application           within      180       days    of       receiving       the
    Abbreviated New Drug Application.                        
    Id.
     § 355(j)(5)(A).                However,
    the effective date of the FDA’s approval is dependent on several
    factors, including which of the four certifications the generic
    company used.          In the case of a Paragraph IV certification, the
    timing      of   the      FDA’s       approval          of    an     Abbreviated           New   Drug
    Application depends on whether the brand-name company brings an
    action to defend its patent.                      If it does, the FDA’s approval of
    the Abbreviated New Drug Application is stayed for 30 months.
    Id.    If, during that 30-month stay, “a court decides that such
    patent is invalid or not infringed, the approval shall be made
    effective        on    the       date       of    the        court    decision.”              Id.    §
    (j)(5)(B)(iii)(I).
    If more than one applicant submits an Abbreviated New Drug
    Application        with      a     Paragraph        IV       certification,           the    statute
    provides that a later-filed “application shall be made effective
    not earlier than one hundred and eighty days after” either (1)
    7
    the date that the FDA received notice that the first-filer began
    marketing the drug; or (2) “the date of a decision of a court in
    an action [brought by the brand-name company against the company
    filing the Abbreviated New Drug Application] holding the patent
    which is the subject of the certification to be invalid or not
    infringed”—also known as the “court-decision trigger.”                       Id. §
    (j)(5)(B)(iv).      This   180-day   exclusivity           period,    potentially
    worth   millions   of   dollars,    is   meant        to   incentivize      generic
    pharmaceutical     companies   to    bear       the    costs    of    the   patent
    infringement lawsuit.      Teva Pharm., USA, Inc. v. Leavitt, 
    548 F.3d 103
    , 104 (D.C. Cir. 2008).
    Finally, when multiple patents protect a brand-name drug
    from competition, the FDA, under the pre-amendment version of
    Hatch-Waxman at issue in this case, took a “patent-by-patent
    approach”   in   determining   whether      a    generic       drug   company   is
    entitled to the 180-day exclusivity period.                 As it explained in
    its letter decision:
    eligibility for 180-day exclusivity would be based on
    which   company   submitted  the  first   paragraph  IV
    certification    challenging   each    listed   patent.
    Therefore, in cases where multiple patents are listed,
    different applicants may have the first paragraph IV
    certification as to different patents and multiple
    ANDA applicants may simultaneously be eligible for
    180-day exclusivity as to the particular patents on
    which they were first.
    8
    J.A. 43.        None of the parties challenge the FDA’s patent-by-
    patent   approach          (while    recognizing         that    the     law   has,    in    the
    interim,    changed          and    that    the    FDA     now    uses     a   drug-by-drug
    approach).
    II.
    Pfizer        produces      the   brand-name        arthritis       drug    Celebrex.
    Celebrex was protected by the following patents listed in the
    Orange Book as of 2003: 5,466,823 (“the ‘823 patent”); 5,563,165
    (“the    ‘165    patent”);          5,760,068      (“the    ‘068       patent”);      and    one
    other patent not at issue in this case.                            In 2003, Teva filed
    Abbreviated          New     Drug     Application         76-898,        which     contained
    Paragraph       IV    certifications        as     to    the     ‘823,    ‘165,    and      ‘068
    patents.        Pfizer       sued    Teva   for     patent       infringement,        and    the
    District Court of New Jersey held that all three patents were
    valid and infringed by Teva.                 Pfizer, Inc. v. Teva Pharms. USA,
    Inc., 
    482 F. Supp. 2d 390
     (D.N.J. 2007).                          The Federal Circuit,
    however, reversed in part, deeming eleven of the claims in the
    ‘068 patent invalid.                Pfizer, Inc. v. Teva Pharms. USA, Inc.,
    
    518 F.3d 1253
     (Fed. Cir. 2008).
    Teva then resubmitted its certifications as to the ‘823 and
    ‘165    patents       as   “Paragraph       III    certifications”—that            is,      they
    sought approval of their Abbreviated New Drug Application only
    subsequent      to     the    expiration      of    those       two    patents.        See    21
    
    9 U.S.C. § 355
    (j)(2)(A)(vii).            Meanwhile, several other generic
    drug    manufacturers,   including      Mylan,     Watson      and   Lupin,      filed
    Abbreviated      New   Drug    Applications        for    Celebrex         based     on
    Paragraph IV certifications.
    On March 5, 2013, the United States Patent and Trademark
    Office (“PTO”) reissued the invalidated ‘068 patent as RE44048
    (“the    ‘048   patent”),     Pfizer   notified     the    FDA,      and   two     days
    later, the FDA listed the ‘048 patent in the Orange Book.                            On
    March 7, 2013, Teva, Mylan, and Watson amended their Abbreviated
    New Drug Applications so that their Paragraph IV certifications
    included the reissued patent.          And Lupin amended its Abbreviated
    New Drug Application on March 28, 2013.               Again, Pfizer sued for
    patent infringement.
    One year later, in March 2014, the District Court for the
    Eastern District of Virginia deemed the ‘048 patent invalid for
    substantially the same reasons that the ‘068 patent had been
    invalidated.     G.D. Searle LLC v. Lupin Pharms., Inc., No. 2:13-
    cv-00121 (E.D. Va. Mar. 12, 2014).           Teva and Pfizer entered into
    a   settlement    agreement    allowing     Teva    to    market     celecoxib       in
    December 2014.     Mylan and Watson also settled with Pfizer.                      Only
    Lupin remains in the appeal of that decision, which is pending
    in the Federal Circuit.
    During the litigation of the ‘048 patent, the various drug
    manufacturers     engaged     in   letter   writing      and   private      meetings
    10
    with    the   FDA     inquiring      into     how       the    agency     would      approach
    approval of their celecoxib Abbreviated New Drug Applications.
    On April 24, 2014, the FDA issued a letter decision addressed to
    “Celecoxib ANDA Applicant.”                 The question the FDA purported to
    answer    was    “whether      a    prior     court      decision        on   the    original
    patent   triggered       (and      exhausted)       any       exclusivity       to   which   a
    first applicant on the original patent was entitled.”                                J.A. 41.
    Underlying      the    FDA’s       question    was       the       assumption    “that     the
    reissued patent cannot be the basis for a new period of 180-day
    exclusivity[.]”        J.A. 49.       The FDA concluded that:
    for purposes of 180-day exclusivity, upon the listing
    of a reissued patent, a prior court decision on the
    original patent is not regarded as having triggered
    180-day exclusivity for the single bundle of patent
    rights represented by the original and reissued
    patent.    In such a case, eligibility for 180-day
    exclusivity is only available to the applicant that
    first filed a paragraph IV certification to the
    original patent, and that applicant must make a timely
    submission of a paragraph IV certification to the
    reissued   patent  to  remain  eligible   for  180-day
    exclusivity.
    J.A. 51.        The letter decision stated that the FDA was merely
    clarifying      “the     regulatory      framework            to    be   applied      to   the
    relevant ANDAs when such exclusivity determination is made[,]”
    and    “not     making     a    determination           with        respect     to    180-day
    exclusivity in a particular case[.]”                    J.A. 46.
    The following day, April 25, 2014, Mylan sought injunctive
    and    declaratory       relief     against       the    FDA       regarding    its    letter
    11
    decision.        Mylan sought to prevent the FDA from granting any
    other company a 180-day exclusivity period.                             Watson and Lupin
    intervened as plaintiffs, and Teva intervened as a defendant.
    The     district        court     consolidated            the    hearing        on     Mylan’s
    preliminary       injunction       motion       with       a    trial    on     the    merits,
    granted Mylan’s motion for judgment, but in favor of the FDA,
    and dismissed the case.                 Mylan Pharmaceuticals, Inc., v. FDA,
    No. 1:14-cv-00075-IMK Doc. 125 (N.D. W.Va. June 16, 2014).                                  This
    appeal followed.
    III.

    If   step     one   leads       to   the      conclusion        that    Congress      has
    spoken clearly, that is the end of the Chevron inquiry.                                We move
    to Chevron step two only if “devices of judicial construction
    have    been     tried       and      found     to     yield      no    clear        sense    of

    the agency’s answer is based on a permissible construction of
    the statute.” (internal quotation marks omitted)).
    Here,     Congress       has    spoken      directly       regarding      the    court-
    decision     trigger.           The   statute      makes    plain       that    the    180-day
    exclusivity runs from “the date of a decision of a court in an
    action . . . holding the patent which is the subject of the
    certification        to    be     invalid     or     not   infringed.”            
    21 U.S.C. §355
    (j)(5)(B)(iv).           As to generic celecoxib, such a decision was
    reached by the Federal Circuit in 2008.                            Pfizer Inc. v. Teva
    Pharms.     USA,     Inc.,      
    518 F.3d 1253
          (Fed.    Cir.       2008).         That
    decision struck eleven of the claims in Pfizer’s ‘068 patent as
    invalid.       
    Id.
        The ‘068 patent was the subject of the Paragraph
    IV certification that Teva submitted to FDA.                                  Teva’s 180-day
    exclusivity period as to the ‘068 patent began to run from the
    date the Federal Circuit issued its mandate in May 2008.                                      And
    14
    the exclusivity period expired on November 9, 2008, i.e., 180
    days later.
    Hatch-Waxman          does        not        define      “patent”        nor        does    it
    specifically speak to reissued patents.                           This does not, however,
    render       the    statute       ambiguous.             The    “court-decision            trigger”
    speaks       of      “the        patent       which        is     the     subject          of     the
    certification.”             
    21 U.S.C. §355
    (j)(5)(B)(iv) (emphasis added).
    FDA’s interpretation of this language treats the original patent
    and the reissued patent as a single “bundle of rights” which can
    only    be    the     subject       of       one    Paragraph      IV    certification            and
    therefore      provides          only    a    single       180-day      exclusivity         period.
    However, this interpretation is contrary to the plain statutory
    language.
    Black’s        Law        Dictionary           defines      “patent”           as     “[t]he
    governmental         grant        of     a    right,       privilege,          or     authority.”
    Black’s Law Dictionary 1300 (10th ed. 2014).                               It also defines
    “reissue       patent”       as    “[a]       patent      that    is    issued        to    correct
    unintentional or unavoidable errors in an original patent, such
    as to revise the specification or to fix an invalid claim.”                                       Id.
    at 1301.           In other words, a reissue patent exists because of
    some mistake in the original patent.                           It does not grant the same
    “right[s],         privilege[s],             or     authorit[ies]”        as        the    original
    patent because the original cannot protect the rights it claims—
    it     was    issued        in    error        or    was       otherwise       mistake-ridden.
    15
    Instead, it is a separate grant of rights, even if elements of
    the reissued patent overlap with those of the original patent.
    See    
    35 U.S.C. § 251
         (describing        the   reissue   of       defective
    patents).
    The    original      2008     court        decision   triggered      a     180-day
    exclusivity period regarding the ‘068 patent.                      That patent was
    thus “the patent which” was “the subject of the certification”
    Teva sent to FDA in 2003.                 Because the ‘068 patent could not
    protect the rights it claimed, Teva’s marketing of celecoxib
    would not infringe the original patent, at least to the eleven
    invalidated claims.            Teva’s successful challenge of the ‘068
    patent, however, could not address its rights as to the ‘048
    patent, which did not come into existence until years later.
    The reissued ‘048 patent represented a new set of rights granted
    by the PTO, due to the court-recognized mistake in the original
    ‘068     patent.         The      reissue    necessitated       new    Paragraph       IV
    certifications and a subsequent legal challenge to determine the
    patent’s validity.          Because the statute requires recertification
    as to a reissued patent, the ‘048 reissued patent thus was also
    “the patent which” was “the subject of the certification[s]”
    that Mylan, Teva, and Watson issued in 2013 and that led to
    litigation.
    The   plain      language     of     the    statute    indicates     that     each
    patent      that   is   the    subject       of    a   certification     may      trigger
    16
    exclusivity.         The Hatch-Waxman Act required Abbreviated New Drug
    Application applicants to certify as to both the original and
    reissued patents; each could be “the patent which is the subject
    of the certification.”           
    21 U.S.C. §355
    (j)(5)(B)(iv).              Because we
    find    that    FDA’s   interpretation         to    the   contrary   violated      the
    plain    statutory      language,   we    must       set   it   aside.      Household
    Credit Servs., Inc. v. Pfennig, 
    541 U.S. 232
    , 239 (2004) (“If
    [Congress has spoken to the question at issue], courts, as well
    as the agency, must give effect to the unambiguously expressed
    intent of Congress.”).           See also Mylan Pharms., Inc. v. FDA, 
    454 F.3d 270
    , 274-75, 276-77 (4th Cir. 2006) (holding that 
    21 U.S.C. § 355
    (j)(5)(B)(iv)       was   plain    and       therefore   the   court   had   no
    choice but to enforce the language as written).
    IV.
    For    the    reasons    above,    we        reverse    and      remand   with
    instructions for the district court to proceed with adjudicating
    the rights of the Abbreviated New Drug Application applicants
    consistent with this opinion.
