    OPINION OF THE COURT
    ALITO, Circuit Judge:
    Kanebridge Corporation   ("Kanebridge") appeals the
    District Court's order   granting a preliminary injunction in
    favor of Southco, Inc.   ("Southco"). Because wefind that
    Southco's part numbers   are not entitled to copyright
    protection, we reverse   the District Court's order.
    I.
    Southco manufactures various types of captive screw
    fasteners, devices used in assembling the panels of items
    such as computers and telecommunications equipment. 1
    Important characteristics that distinguish among the huge
    variety of fasteners include their length, thread size, finish,
    recess type, installation type, screw diameter, and
    composition. To assist its employees and customers in
    identifying and distinguishing among its products, Southco
    developed a numbering system to serve as a shorthand
    description of the relevant characteristics of each fastener.
    Under this system, each fastener is assigned a unique nine-
    digit number, with each digit describing a specific physical
    parameter of the fastener.2 Southco includes these numbers
    _________________________________________________________________
    1. Southco describes these fasteners as follows:"Captive screws are used
    to fasten panels together. Each captive screw comprises a screw, a
    ferrule and a knob. A set of screws will be mounted in one panel by
    means of the ferrule and the other panel contains an internally threaded
    insert which receives the screw." Appellee's Brief at 6-7.
    2. Southco's brief illustrated how its numbering system works by
    including the following description of part numbers 47-10-202-10 and
    47-11-202-10:
    47-10-202-10
    The first two digits ("47") refer to Southco's line of captive
    fasteners,
    as opposed to other Southco product lines. The next two digits
    ("10")
    refer to an English thread with either a flare orfloating style
    ferrule
    with a specific screw projection. In particular, the specific
    digits
    ("10") indicate that the screw is so short that it does not project
    3
    in various Handbooks it publishes each year.3 Anyone who
    is familiar with Southco's system should be able to
    determine all of the relevant features of a particular screw
    from its part number alone. This numbering system has
    become an industry standard, and the part numbers
    produced by the system are the subject of this copyright
    infringement suit.
    Matdan America ("Matdan") is a competing manufacturer
    of panel fasteners. Kanebridge, known as Matdan's"master
    distributor," sells Matdan fasteners to other distributors,
    often at prices lower than Southco's. Because Southco's
    numbering system has become an industry standard, many
    _________________________________________________________________
    outside the ferrule when the installed captive fastener is in the
    unfastened state. In the next series of digits ("202"), the first
    digit
    ("2") refers to the specific thread size ("632"). The next digit
    ("0")
    indicates a slotted recess on top of the screw. The next digit
    ("2")
    refers to the grip length of that flange, where the parts attach to
    the
    panel. In this case, the "2" indicates that the flange grip length
    is
    appropriate for panel with a thickness from 0.058 inches and 0.125
    inches. In the last two digits, the first digit ("1") indicates the
    type
    of material that the ferrule is made out of (aluminum) and that the
    knob has a natural finish. The last digit ("0") indicates whether
    the
    knob is knurled or smooth. The "0" indicates that the knob is
    knurled.
    47-11-202-10
    This number signifies a captive fastener that is identical, except
    that
    the second pair of digits ("11") refer to an English thread with a
    flare
    or floating style ferrule with a different screw projection. In
    this case
    the screw is long enough to project from the ferrule even when the
    captive fastener is unfastened.
    3. Southco obtained copyright registrations for these Handbooks, but the
    registrations do not refer to the part numbers. In addition to the part
    numbers, the Handbooks contain, among other things, short
    descriptions and drawings of the various products. The parties do not
    appear to dispute that the Handbooks are entitled to copyright
    protection, and it is well-established that compilations can be
    copyrighted, assuming that the compiler "make[s] the selection or
    arrangement independently (i.e. without copying that selection or
    arrangement from another work), and that it display some minimal level
    of creativity." Feist Publications, Inc. v. Rural Tel. Serv. Co., 
    499 U.S. 340
    ,
    358 (1991).

    of Kanebridge's customers often specify suitable fasteners
    by reference to Southco's part numbers. Recognizing this
    fact, Kanebridge began using Southco's part numbers in
    comparison charts that were included in advertisements
    and other literature that it provides to customers. These
    charts display Kanebridge's and Southco's numbers for
    equivalent fasteners in adjacent columns, making it clear
    that these parts are interchangeable.4 According to
    Kanebridge, the "ability to cross-reference Southco panel
    fasteners in an honest, accurate and comparative manner"
    is necessary to make competition viable. Appellant's Brief at
    7. Without this ability, customers would lose the
    opportunity to obtain lower-cost alternative fasteners. 
    Id. Southco commenced
    this action against Kanebridge
    asserting, among other claims, a claim for copyright
    infringement. The parties agreed to a temporary restraining
    order ("TRO") containing various restrictions on
    Kanebridge's use of Southco's part numbers. They also
    agreed to enter into a preliminary injunction on consent
    but were unable to agree on its scope. Southco then moved
    for a preliminary injunction of the same scope as the TRO,
    and after a hearing, the District Court issued an order
    granting Southco's motion. Kanebridge is appealing this
    order.
    II.
    The decision whether to enter a preliminary injunction is
    committed to the sound discretion of the trial court and will
    be reversed "only if the court abused its discretion,
    committed an obvious error in applying the law, or made a
    serious mistake in considering the proof." Loretangeli v.
    Critelli, 
    853 F.2d 186
    , 193 (3d Cir. 1988); see also Times
    Mirror Magazines, Inc. v. Las Vegas Sporting News, L.L.C.,
    
    212 F.3d 157
    , 160-61 (3d Cir. 2000). Although the scope of
    our review is limited, "any determination that is a
    prerequisite to the issuance of an injunction . . . is reviewed
    according to the standard applicable to that particular
    _________________________________________________________________
    4. Southco claims that Matdan's fasteners, although interchangeable
    with its own, are of inferior quality. Whether or not this is true,
    however,
    is irrelevant to the present appeal.

    determination." American Tel. and Tel. Co. v. Winback and
    Conserve Program, Inc., 
    42 F.3d 1421
    , 1427 (3d Cir. 1994)
    (quoting John F. Harkins Co., Inc. v. Waldinger Corp., 
    796 F.2d 657
    , 658 (3d Cir. 1986)). Therefore, "we exercise
    plenary review over the District Court's conclusions of law
    and its application of the law to the facts." Duraco Products,
    Inc. v. Joy Plastic Enterprises, Ltd., 
    40 F.3d 1431
    , 1438 (3d
    Cir. 1994); see also Marco v. Accent Publ'g Co. , 
    969 F.2d 1547
    , 1548 (3d Cir. 1992).
    III.
    Kanebridge challenges the District Court's grant of a
    preliminary injunction on two separate grounds. First, it
    argues that Southco's part numbers fail to satisfy the
    requirements for copyright protection. Kanebridge gives
    three reasons to support this argument: the part numbers'
    lack of sufficient originality, the scenes a faire doctrine, and
    the merger doctrine. Second, Kanebridge argues that, even
    if the part numbers are protected, its use of the numbers
    satisfies the requirements for fair use. Because we conclude
    that these numbers fail to satisfy the originality
    requirement, we do not reach any of the other arguments.
    A.
    Copyright protection is available for "original works of
    authorship fixed in any tangible medium of expression." 17
    U.S.C. S 102(a) (emphasis added). The Supreme Court has
    held that, in order to satisfy the originality requirement, a
    work must have been "independently created by the author"
    and must possess "at least some minimal degree of
    creativity." Feist Publications, Inc. v. Rural Tel. Serv. Co.,
    Inc., 
    499 U.S. 340
    , 345 (1991). Although the Court has
    noted that this is not a "stringent" standard, it has also
    held that there is "a narrow category of works in which the
    creative spark is utterly lacking or so trivial as to be
    virtually nonexistent." 
    Id. at 358-59.
    We conclude that
    Southco's part numbers fit within this "narrow category" of
    works that are incapable of sustaining a valid copyright. 
    Id. At the
    outset, we must determine exactly what work
    Southco claims is entitled to copyright protection. There are
    6
    three possibilities: (1) the numbering system, (2) the actual
    part numbers, and (3) both the system and the numbers.
    The District Court apparently did not distinguish among
    these three options. Although it framed the issue as
    "whether Kanebridge may use Southco numbers in
    comparison charts," the Court's analysis repeatedly referred
    to the "Numbering System." Southco, Inc. v. Kanebridge
    Corp., No. CIV. A. 99-4337, 
    2000 WL 21257
    , at *2 (E.D.Pa.
    Jan. 12, 2000) (emphasis added). For example, when
    discussing the originality requirement, the Court stated:
    "The Numbering System is sufficiently original for copyright
    protection." 
    Id. at 3
    (emphasis added). For purposes of
    copyright law, however, Southco's numbering system itself
    and the actual numbers produced by the system are two
    very different works.5
    Southco has not alleged that Kanebridge improperly used
    its numbering system. Instead, it alleges that Kanebridge
    infringed its copyright in the actual part numbers. This
    case does not involve Kanebridge's creation of a new
    fastener and its use of the Southco numbering system to
    assign that part a part number. That hypothetical situation
    would raise issues not present in this appeal.6 We believe
    _________________________________________________________________
    5. As the amicus brief submitted on behalf of the United States Patent &
    Trademark Office aptly notes:
    The district's court's originality analysis addressed the
    originality
    not of the 51 nine-digit numbers Southco alleged Kanebridge to
    have copied, but rather of the "Numbering System." . . . The court
    found that system to be original and protected by Southco's
    registered copyrights. Whatever the merits of thosefindings, they
    do
    not compel, nor even suggest, a conclusion that the parts numbers
    are protected by copyright.
    Amicus Brief of the United States at 14.
    6. For example, the United States raises the question whether the system
    amounts to a set of abstract rules that is ineligible for copyright
    protection under 17 U.S.C. 102(b). Amicus Br. For the United States at
    14 n.12. We express no opinion on this issue. However, we do point out
    that, in response to questions at oral argument, Southco's attorney
    conceded that the system itself is not eligible for copyright protection.
    This issue does not affect the outcome of this case.
    7
    that, given Southco's allegations, the proper focus of our
    analysis must be on the actual part numbers.7
    B.
    To satisfy the originality requirement, Southco's part
    numbers must "display some minimal level of creativity."
    See 
    Feist, 499 U.S. at 358
    . Although the originality
    requirement is not demanding, it nevertheless is a
    prerequisite for copyright protection since copyright
    protection is available only for "original works of
    authorship." 17 U.S.C. S 102(a) (emphasis added); see also
    
    Feist, 499 U.S. at 345
    ("The sine qua non of copyright is
    originality."). Indeed, "[o]riginality is a constitutional
    requirement." 
    Feist, 499 U.S. at 346
    . We conclude that the
    creative spark is utterly lacking in Southco's part numbers
    and that these numbers are examples of works that fall
    short of the minimal level of creativity required for
    copyright protection.
    Although the District Court reached the opposite
    conclusion, its own words demonstrate that Southco's part
    numbers are completely devoid of originality and instead
    result from the mechanical application of the numbering
    system. As the District Court stated,
    Southco uses product numbers that convey specific
    properties of the products manufactured. The numbers
    are not assigned at random or in sequence; they are
    assigned based on the properties of the parts. The
    Numbering System is a complex code expressing
    numerous detailed features of Southco hardware
    _________________________________________________________________
    7. An analogy to patent law may be helpful to illustrate the importance
    of this distinction. If someone obtains a process patent for a machine
    that manufactures widgets, that person has a monopoly in the rights to
    the machine. However, unless the widgets themselves also satisfy the
    requirements for patent protection and the application contains claims
    related to the widgets, that person will have no patent rights in the
    widgets and will not succeed in an infringement suit against someone
    who produces identical widgets through a process that does not infringe
    the patent for the machine. His/her patent rights will be limited to the
    machine that produces the widgets. See United States v.
    Studiengesellschaft Kohle, 
    670 F.2d 1122
    , 1127-28 (D.C. Cir. 1981).
    8
    products; each part number tells the story of a part's
    size, finish, and utility. Southco does not make random
    and arbitrary use of numbers; Southco assigns
    numbers based on a system designed over twenty years
    ago and refined ever since.
    Southco, 
    2000 WL 21257
    , at *4. Southco also acknowledges
    this fact in its brief by stating that its system"is made up
    of nine-digit part numbers in which the first two numbers
    denote the type of fastener and the remaining digits denote
    functional characteristics of each type, such as installation
    type, thread size, recess type, grip length, type of material,
    and knob finish." Appellee's Brief at 7. Southco also refers
    to its system as a "code which communicates details of the
    hardware." 
    Id. Southco unquestionably
    devoted time, effort, and thought
    to the creation of the numbering system, but Southco's
    system makes it impossible for the numbers themselves to
    be original. Under that system, there is simply no room for
    creativity when assigning a number to a new panel
    fastener. The part has certain relevant characteristics, and
    the numbering system specifies certain numbers for each of
    those characteristics. As a result, there is only one possible
    part number for any new panel fastener that Southco
    creates. This number results from the mechanical
    application of the system, not creative thought. If Southco
    were to develop a new fastener and for some reason decide
    to exercise creativity when assigning it a number, the
    resulting part number would fail to accomplish its purpose.
    Regardless of how small the change is, customers could not
    effectively identify the relevant characteristics of the panel
    fastener by simply looking at its part number.
    C.
    The District Court devoted significant attention to two
    decisions from other circuits, and the parties' briefs take
    the same approach. These decisions, Toro Co. v. R&R
    Products Co., 
    787 F.2d 1208
    (8th Cir. 1986), and Mitel, Inc.
    v. Iqtel, Inc., 
    124 F.3d 1366
    (10th Cir. 1997), are of course
    not binding on this Court, and neither directly addresses
    the precise ground on which our current decision is based.
    9
    In Toro, the Eighth Circuit held that a lawn care machine
    manufacturer's part numbering system lacked sufficient
    originality for copyright protection. See Toro , 787 F.2d at
    1213. The manufacturer arbitrarily assigned a random
    sequential number to each new part it created and offered
    no evidence that the numbers used were intended to
    encode any information. See 
    id. The Court
    stated: "The
    random and arbitrary use of numbers in the public domain
    does not evince enough originality to distinguish
    authorship." 
    Id. In dicta,
    however, the Court went on to
    say:
    This is not to say that all   parts numbering systems are
    not copyrightable. A system   that uses symbols in some
    sort of meaningful pattern,   something by which one
    could distinguish effort or   content, would be an
    original work.
    
    Id. Both Southco
    and the District Court have seized on this
    dicta and argued that Toro supports a finding of
    copyrightability for Southco's part numbers since those
    numbers are not randomly assigned.
    We agree with Kanebridge that reliance on Toro is
    unfounded. For one thing, the Toro Court, in analyzing the
    issue of originality, invoked the "sweat of the brow" theory,
    under which courts considered the amount of effort
    expended by an "author" in assessing whether a work was
    original. 
    See 787 F.2d at 1213
    (relying on Hutchinson Tel.
    Co. v. Frontier Directory Co., 
    770 F.2d 128
    (8th Cir. 1985)).
    The Toro Court relied, at least in part, on this theory in
    making the statement on which Southco and the District
    Court have relied. 
    See 787 F.2d at 1213
    ("A system that
    uses symbols in some sort of meaningful pattern,
    something by which one could distinguish effort or content,
    would be an original work.")(emphasis added). However, the
    Supreme Court has clearly rejected the "sweat of the brow"
    theory. See 
    Feist, 499 U.S. at 352-61
    ("Without a doubt, the
    ``sweat of the brow' doctrine flouted basic copyright
    principles."). In addition, Toro stated only that a parts
    numbering "system" that used symbols in a meaningful
    pattern would be 
    original. 787 F.2d at 1213
    . Here, as we
    have emphasized, the issue is not the originality of
    Southco's system but of its parts numbers themselves. For
    10
    these reasons, we do not believe that Toro supports a
    finding of copyrightability in this case.
    The Tenth Circuit's decision in Mitel likewise does not
    support Southco's argument. The Mitel Court addressed the
    issue of copyrightability of four-digit computer codes used
    to operate telecommunications equipment.8 The Court first
    held that the four digits making up these codes themselves
    -- the "registers" (the first three digits) and "descriptions"
    (the fourth digit) - were not original and therefore not
    copyrightable. These numbers were arbitrarily chosen and
    largely sequential, and the Court concluded that" ``the
    random and arbitrary use of numbers in the public domain
    does not evince enough originality to distinguish
    authorship.' 
    " 124 F.3d at 1374
    (quoting District Court).
    However, the Court reached a different conclusion with
    respect to the "values" assigned to the "descriptions." 
    Id. at 1374.
    One such "value" that the Court described concerned
    the appropriate response "upon the failure of a call sent
    over a particular telephone network route." 
    Id. "The possible
    values for th[is] function include[d] several
    combinations of redialing over another route or
    reattempting the call over the same route again before
    trying another route." 
    Id. The Tenth
    Circuit held that Mitel's
    values reveal ``the existence of . . . intellectual production,
    of thought, and conception.' " 
    Id. (quoting Feist,
    499 U.S. at
    362). The Court stated that Mitel employees satisfied the
    ``minimal degree of creativity' requirement by"devis[ing]
    _________________________________________________________________
    8. Kanebridge accurately and succinctly described the command codes
    that were at issue in Mitel as follows:
    The four-digit codes included a "register", consisting of the first
    three digits, and a "description", consisting of the last digit.
    Each
    three-digit register identified a particular function. Particular
    numbers in the description digit corresponded to certain "values"
    pertaining to the function identified by the register. For example,
    register "X27" identified the function "Time to Auto Answer",
    wherein
    X indicated the number of the telephone line for which the function
    would be activated. With regard to the description, a "4" stood for
    the value of "40 seconds" for the "Time to Auto Answer" function.
    Other values for this function denoted other time durations. For
    other functions, values represented various baud rates.
    Kanebridge's Brief at 31-32.
    11
    appropriate values for the wide variety of individual
    functions." 
    Id. Despite this
    finding of originality, the court
    denied copyright protection to these values under the
    scenes a faire doctrine.
    The District Court, without any explanation, declared
    that "Southco's Numbering System is original under this
    portion of the Mitel analysis." This reliance on Mitel,
    however, was misplaced.9 We agree with Kanebridge that
    the values in Mitel are not analogous to the part numbers
    in this case. Instead, they are more closely analogous to the
    physical specifications of the parts. For example, the
    number "4" as a description in one of the codes in Mitel
    stood for the value of "40 seconds." This is simply an
    operational parameter. The number "4" just as easily could
    have stood for values of "4 seconds," "44 seconds," "83
    seconds," or any other amount of time. It was in making
    this decision that the value should be "40 seconds" that the
    Mitel employees exercised creativity. At best, this would be
    analogous to Southco's choosing the length to make a
    particular fastener. For example, it would be analogous to
    Southco's deciding between making a particular fastener
    200 millimeters or 300 millimeters in length. This is not the
    same as deciding that the number "2" in its numbering
    system should represent a fastener that is 632 millimeters.
    For this reason, we do not believe that Mitel supports a
    finding of copyrightability in this case.
    Finally, we believe that it is important to address a third
    case that the District Court and the parties have not
    discussed. In American Dental Association v. Delta Dental
    Plans Association, 
    126 F.3d 977
    (7th Cir. 1997), the
    Seventh Circuit held that a "taxonomy" used by the
    American Dental Association ("ADA") was copyrightable.
    This taxonomy classified various dental procedures into
    groups and assigned to each procedure a five-digit number,
    _________________________________________________________________
    9. In its brief, Southco stated, "The values in Mitel were found to be
    copyrightable however, even though single digits, because they were
    established according to a system." Appellee's Brief at 19-20. The Mitel
    Court reached no such holding and did not refer to the values being
    established according to a system when concluding that they satisfied
    the originality requirement. Therefore, we disagree with Southco's
    characterization of the court's holding.

    a short description, and a long description.10 See 
    id. at 977.
    This taxonomy was used to create the "Code on Dental
    Procedures and Nomenclature," a compilation of all of the
    potentially billable dental procedures. Delta, a corporation
    that provides and administers various member dental care
    service plans, published its own book entitled "Universal
    Coding and Nomenclature." This book included most of the
    numbering system and short descriptions from the ADA's
    Code. See 
    id. The District
    Court held that the ADA's
    taxonomy was not copyrightable.
    In reversing the District Court, the Seventh Circuitfirst
    expressed concern that the District Court's decision was so
    sweeping that it would remove copyright protection from
    many other well-established "taxonomies," such as the
    West Key Number System and the manuals issued by the
    Financial Accounting Standards Board to specify generally
    accepted accounting practices. See 
    id. at 978.
    The Court
    went on to hold that the ADA's taxonomy was entitled to
    copyright protection. See 
    id. at 979.
    The Court observed:
    Facts do not supply their own principles of
    organization. Classification is a creative endeavor.
    Butterflies may be grouped by their wings, or their
    feeding or breeding habits, or their habitats, or the
    attributes of their caterpillars, or the sequence of their
    DNA; each scheme of classification could be expressed
    in multiple ways. Dental procedures could be classified
    by complexity, or by the tools necessary to perform
    them, or by the parts of the mouth involved, or by the
    anesthesia employed, or in any of a dozen different
    ways.
    
    Id. The court
    added:
    Creativity marks the expression even after the
    fundamental scheme has been devised. This is clear
    enough for the long description of each procedure in
    the ADA's Code. The long description is part of the
    copyrighted work, and original long descriptions make
    _________________________________________________________________
    10. For example, the number 04267 is assigned to the short description
    "guided tissue regeneration -- nonresorbable barrier, per site, per tooth
    (includes membrane removal)." American Dental 
    Ass'n, 126 F.3d at 977
    .

    the work as a whole copyrightable. But we think that
    even the short description and the number are original
    works of authorship.
    
    Id. We believe
    that there are important distinctions between
    American Dental and the present case. The long and short
    descriptions of the various dental procedures are obviously
    very different from the part numbers at issue in the present
    case, and therefore the Seventh Circuit's decision that
    these descriptions are copyrightable has no application
    here. Moreover, even the numbers assigned to the
    procedures appear to be quite different. These numbers
    were not chosen randomly, as were the numbers in Toro or
    the computer codes in Mitel, and they were not the
    mechanical results of a numbering system, as are the part
    numbers in question in this case. Rather, the numbers in
    American Dental reflected creative thought. The entries in
    the ADA's Code were originally developed by a committee
    comprised of representatives from interested organizations.
    See American Dental Ass'n v. Delta Dental Plans Ass'n, No.
    92-C-5909, 
    1996 WL 224494
    , at *2-3 (N.D.Ill. May 1, 1996).
    When new procedures were developed or other changes to
    the system became necessary, this committee collected
    written proposals submitted by state dental societies and
    national dental organizations. The committee then debated,
    edited, and voted on the proposals. See 
    id. at *3.
    Although
    the ADA eventually changed this process, the new process
    still involved significant debate and editing of proposals by
    this committee. See 
    id. at *4.
    Assigning a number to a particular dental procedure
    reflects a decision about the distinctiveness and prevalence
    of the procedure and its relationship to the other
    procedures in the Code. Each number series in the Code
    refers to a particular category of procedures. For example,
    the 00100-00999 series refers to "Diagnostic" procedures,
    and the 02000-2999 series refers to "restorative
    procedures." And it appears that closely related procedures
    are grouped within each series. For example, the 2100
    series, which is grouped under the heading "Amalgam
    Restorations (including polishing)," is as follows:
    14
    02110   amalgam   -   one surface, primary
    02120   amalgam   -   two surfaces, primary
    02130   amalgam   -   three surfaces, primary
    02131   amalgam   -   four or more surfaces, primary
    02140   amalgam   -   one surface, permanent
    02150   amalgam   -   two surfaces, permanent
    02160   amalgam   -   three surfaces, permanent
    02161   amalgam   -   four or more surfaces, permanent
    American Dental Association, Current Dental Terminology,
    at 10 (1st ed. 1990-1995). Thus, assigning a particular
    number to a particular procedure involved at least a
    modicum of creativity.
    The ADA's system stands in stark contrast to Southco's.
    As previously discussed, Southco's system is highly
    mechanical and leaves no room for creativity. When a new
    fastener is created, there is only one possible part number.
    Assigning a particular number to the fastener does not
    involve any creativity or any choice about how the fastener
    should be classified. Accordingly, even if we were bound by
    American Dental, we would not regard it as controlling here.
    In sum, we conclude that the District Court committed
    an error in holding that the Southco numbers satisfied the
    originality requirement of the Copyright Act. We hold that
    Southco has no likelihood of success in its infringement
    action and that the entry of the preliminary injunction in
    its favor was not proper. We therefore reverse the order of
    the District Court.
