    OPINION
    _________________
    BERNICE BOUIE DONALD, Circuit Judge. This is a copyright dispute over the use of
    software code and technical drawings for an industrial control system related to plastic injection
    molding. The district court held that Plaintiff-Appellant RJ Control Consultants, Inc. and its sole
    shareholder, Paul Rogers, (collectively, “Plaintiffs”) failed to establish copyright infringement
    No. 20-1009              RJ Control Consultants, Inc., et al. v. Multiject, LLC, et al.                       Page 2
    because the use of a design to manufacture a control system does not constitute copyright
    infringement. The district court accordingly granted summary judgment against Plaintiffs on
    their copyright infringement claim. The district court further granted summary judgment against
    Plaintiffs as to their Lanham Act claim, declined to exercise supplemental jurisdiction over the
    remaining state law claims, and denied as moot Plaintiffs’ motion to compel discovery.
    Plaintiffs appeal the order denying reconsideration of the district court’s grant of summary
    judgment as to the copyright claim as well as the denial of their motion to compel as moot.
    I.
    The district court characterized this as a “business dispute which soured a friendship.”
    That friendship was between Plaintiff-Appellant Paul Rogers and Defendant-Appellee Jack
    Elder. Rogers was the principal and sole shareholder of RJ Control Consultants, Inc. (“RJ
    Control”), a Michigan company that creates industrial control systems. Elder is the sole owner
    of Defendant-Appellee Multiject, LLC (“Multiject”), a Michigan business which engineers and
    sells various industrial accessories related to plastic injection molding. Their friendship turned
    into a business relationship when Elder approached Rogers seeking Rogers’s expertise and
    assistance in developing a control system for an injection molding machine.
    In 2008, Rogers and Elder entered into an oral agreement whereby Rogers would develop
    a rotary turntable control system for Elder and Multiject. This turntable control system is the
    “brain” of the turntable, allowing the turntable to move and operate. RJ Control, through
    Rogers’s work, updated the control system design in 2013, labeling the newest iteration as
    “Design 3.” The parties dispute the invoicing for Design 3.1
    In March of 2014, Elder asked Rogers for copies of Design 3’s diagrams as well as the
    software source code “in case something happened” to Rogers.                               Rogers disclosed that
    information to Multiject, believing that Multiject and Elder would not improperly use or disclose
    the information to third parties. Three days after providing that information to Multiject, Elder
    informed Rogers and RJ Control that Elder and Multiject would no longer need Rogers’s
    1In their briefing, the parties explain in detail the various contractual disputes raised in the district court.
    Because Rogers and RJ Control do not appeal the district court’s dismissal of the state law claims—the only claims
    for which these facts are relevant—we do not address those facts here.
    No. 20-1009         RJ Control Consultants, Inc., et al. v. Multiject, LLC, et al.      Page 3
    services and would instead use Defendant-Appellee RSW Technologies, LLC (“RSW”) for the
    assembly and wiring of the control systems. Elder said that Multiject would like to continue
    working with Rogers as a technical consultant for the system design and that Multiject
    appreciated his expertise but that “this comes down to a business decision.”
    Multiject and RSW—RJ Control’s replacement—had a long-standing business
    relationship with each other, and Multiject was already considering switching to RSW when it
    asked Rogers for the design diagrams. Elder claims that Multiject was increasingly concerned
    with Rogers’s pricing, worrying that Rogers was charging Multiject too much relative to
    competitors, at least to the extent Rogers was performing manual labor rather than designing the
    systems. For that reason, Elder and Multiject decided to “switch out” RJ Control and Rogers for
    RSW, for purposes of manufacturing rotary tables.
    On the same day that Elder informed Rogers that Multiject would be using RSW to
    assemble and wire the control systems, RSW sent Elder a quote that explicitly referenced the
    assembly and wiring of “RJ Table Control.” Elder, Multiject, and RSW used Design 3—both the
    software code and the technical drawings—in the assembly and wiring of new control systems.
    RSW did not make any changes in the design when it used Design 3. RSW claims that it did not
    know Rogers and RJ Control had separately designed Design 3 and did not know there was
    dispute as to whether Elder properly paid Rogers for that work; that is to say, RSW believed
    Multiject had permission to build the control systems using the software and technical drawings.
    On February 17, 2016—nearly two years after Rogers initially supplied the software code
    and technical drawings to Elder—Rogers obtained two Copyright Certificates of Registration:
    one for the “Control System Turn Table Software: Design 3” (i.e., the software code) and
    another for “Control System Turn Table Schematics: Design 3” (i.e., the technical drawings).
    Nearly two weeks after receiving those copyrights, RJ Control brought suit against
    Multiject, Elder, and RSW. Over a year later, RJ Control filed an amended complaint, adding
    Rogers as a plaintiff. That amended complaint brought several federal and state law claims:
    (1) copyright infringement, (2) trademark infringement, (3) violation of the Michigan Consumer
    Protection Act, (4) breach of contract, (5) unjust enrichment, (6) conversion, and (7) tortious
    No. 20-1009              RJ Control Consultants, Inc., et al. v. Multiject, LLC, et al.                      Page 4
    interference with contract/business expectancy. RSW and Elder/Multiject separately brought
    motions for summary judgment on all claims. Before the district court ruled on those motions,
    Plaintiffs brought a motion to compel discovery responses. On November 8, 2018, the district
    court granted Defendants’ motions for summary judgment. In doing so, the court dismissed the
    two federal claims (copyright and trademark infringement) with prejudice. The court dismissed
    the state law claims without prejudice, declining to exercise supplemental jurisdiction after the
    dismissal of the federal claims. Finally, the court denied as moot Plaintiffs’ motion to compel.
    That same day, the district court entered its final judgment dismissing the case.
    That was not, however, the end of the matter. Plaintiffs thereafter filed a motion for
    reconsideration of the dismissal of the copyright claim and denial as moot of their motion to
    compel. The district court denied that motion on January 18, 2019, but a week later set a hearing
    on the motion. Nearly two weeks later, the district court vacated its prior denial of the motion.
    At the hearing on February 11, 2019, the district court expressed interest in seeing the entire
    software code as it reconsidered its decision, also noting that the court may need an expert in
    making its determination regarding the software’s copyrightability. Plaintiffs thereafter supplied
    the full code to the court.             Ten months later, the district court denied the motion for
    reconsideration, finding that nothing in the papers supplied to the court—the full source code—
    revealed that the court erred in its original dismissal of the copyright-infringement claim. The
    district court provided no further explanation.2 Plaintiffs then brought this appeal.
    II.
    We review a district court’s grant of summary judgment de novo. Gillis v. Miller,
    
    845 F.3d 677
    , 683 (6th Cir. 2017).3 Summary judgment is proper “if the movant shows that
    2The   district judge, Avern Cohn, retired weeks after his denial of Plaintiffs’ motion for reconsideration.
    3The   notice of appeal itself is limited to appealing the denial of Plaintiffs’ motion for reconsideration.
    Nonetheless, “where it can be reasonably inferred from the notice of appeal that the intent of the appellant was to
    appeal from the final judgment” rather than merely the denial of the motion for reconsideration, we may treat the
    appeal as an appeal from the final judgment, particularly where the appellee has not been misled. Peabody Coal Co.
    v. Local Union Nos. 1734, 1508, & 1548, UMW, 
    484 F.2d 78
    , 81 (6th Cir. 1973). Here, the appellees have not been
    misled, particularly considering that both parties have briefed the merits of the underlying motion for summary
    judgment rather than constraining themselves to the motion for reconsideration. See also Boburka v. Adcock,
    
    979 F.2d 424
    , 426 (6th Cir. 1992).
    No. 20-1009          RJ Control Consultants, Inc., et al. v. Multiject, LLC, et al.       Page 5
    there is no genuine dispute as to any material fact and the movant is entitled to judgment as a
    matter of law.” Fed. R. Civ. P. 56(a). The moving party bears the burden of showing that no
    genuine issues of material fact exist. Celotex Corp. v. Catrett, 
    477 U.S. 317
    , 325 (1986). The
    nonmoving party “must set forth specific facts showing that there is a genuine issue for trial,”
    and in turn, the reviewing court must determine “whether the evidence presents a sufficient
    disagreement to require submission to a jury or whether it is so one-sided that one party must
    prevail as a matter of law.” Anderson v. Liberty Lobby, Inc., 
    477 U.S. 242
    , 250-52 (1986). In
    copyright infringement cases, “granting summary judgment, particularly in favor of a defendant,
    is a practice to be used sparingly.” Wickham v. Knoxville Int’l Energy Exposition, Inc., 
    739 F.2d 1094
    , 1097 (6th Cir. 1984).
    III.
    On appeal, Rogers and RJ control argue that the district court erred in granting summary
    judgment as to the copyright claim and in denying their motion to compel as moot. Considering
    first the copyright claim, they argue that Defendants’ access to the copyright, combined with the
    substantial similarity between the control systems, at minimum raises a genuine dispute as to
    whether Defendants copied their works. They argue that the “useful article” exception does not
    apply where the alleged infringer directly copied the article, as they allege Defendants did here.
    Finally, RJ Control and Rogers argue that the district court erred in not considering the copying
    of the software code, instead analyzing only the copying of the technical drawings.
    In their responses, Defendants address the two copyrighted works separately. First,
    considering the software copyright, they argue that “copyright protection does not extend to the
    control system software at issue because it embodies a procedure, a system[,] and a method of
    operating an injection molding machine” and that “[n]o[t] one of these is eligible for copyright
    protection.” Thus, even if the district court did not specifically address the software code in its
    initial opinion granting summary judgment, Plaintiffs cannot claim copyright protection in the
    software code. Second, considering the technical drawings—which the district court did address
    at length—Defendants claim that the use of copyrighted technical drawings to produce a control
    system does not constitute copyright infringement of the technical drawings in the same way that
    making a recipe out of a copyrighted cookbook does not constitute copyright infringement of the
    No. 20-1009             RJ Control Consultants, Inc., et al. v. Multiject, LLC, et al.                   Page 6
    cookbook. Defendants submit that to the extent Plaintiffs seek to protect the use of the technical
    drawings to create something else, such as the control systems here, Plaintiffs should seek
    protection under patent law, not copyright law.
    The Copyright Act protects “original works of authorship fixed in any tangible medium
    of expression.” 
    17 U.S.C. § 102
    (a).4 The owner of the copyright has the exclusive right to
    reproduce the copyrighted work, to prepare derivative works, and to distribute copies of the
    works to the public. 
    Id.
     § 106. However, “[t]he mere fact that a work is copyrighted does not
    mean that every element of the work may be protected.” Feist Publ’ns Inc. v. Rural Tel. Serv.
    Co., 
    499 U.S. 340
    , 348 (1991). The statute limits that protection in two relevant ways. First,
    “[i]n no case does copyright protection for an original work of authorship extend to any idea,
    procedure, process, system, method of operation, concept, principle, or discovery, regardless of
    the form in which it is described, explained, illustrated, or embodied in such a work.” 
    17 U.S.C. § 102
    (b). Second, as applied to rights in “pictorial, graphic, and sculptural work,” the Copyright
    Act “does not afford, to the owner of copyright in a work that portrays a useful article as such,
    any greater or lesser rights with respect to the making, distribution, or display of the useful
    article so portrayed than those afforded to such works under the law . . . in effect on December
    31, 1977.” 
    Id.
     § 113(b).
    A copyright-infringement claim must establish: (1) ownership of a valid copyright, and
    (2) the fact “that the defendant copied protectable elements of the work.” Lexmark Int., Inc. v.
    Static Control Components, Inc., 
    387 F.3d 522
    , 534 (6th Cir. 2004). The first element tests both
    originality and non-functionality which are “presumptively established by the copyright
    registration.” 
    Id.
     A plaintiff may provide “the certificate of a registration made before or within
    five years after first publication of the work” which “shall constitute prima facie evidence of the
    validity of the copyright and of the facts stated in the certificate.” 
    17 U.S.C. § 410
    (c). Once the
    plaintiff produces that copyright certificate, the burden shifts to the defendant to explain why the
    4As   relevant here, software codes may be entitled to copyright protection as “literary works” under
    
    17 U.S.C. § 101
    . Lexmark Int’l Inc. v. Static Control Components, Inc., 
    387 F.3d 522
    , 533 (6th Cir. 2004) (citing
    H.R. Rep. No. 1476 (1976), reprinted in 1976 U.S.C.C.A.N. 5659, 5667 (“The term ‘literary works’. . . includes . . .
    computer programs to the extent that they incorporate authorship in the programmer’s expression of original ideas,
    as distinguished from the ideas themselves.”)). Technical drawings are covered under “pictorial, graph, and
    sculptural works.” 
    17 U.S.C. § 102
    (a)(5).
    No. 20-1009             RJ Control Consultants, Inc., et al. v. Multiject, LLC, et al.                 Page 7
    copyright is invalid. Lexmark, 
    387 F.3d at 334
    . RJ Control had two valid copyrights: one for the
    software (TXu 1-978-284, with an effective registration date of February 17, 2016) and one for
    the technical drawings (VAu 1-234-630, with an effective registration date of February 18,
    2016). Defendants do not assert that the copyrights themselves are invalid but rather that
    Defendants’ use of those drawings does not constitute prohibited copying.5
    Because the validity of the copyrights is not contested, we consider the technical drawing
    and software code copyrights under the second prong. The second prong “tests whether any
    copying occurred (a factual matter) and whether the portions of the work copied were entitled to
    copyright protection (a legal matter).” Lexmark, 378 F.3d at 534.
    A. Copying of the Technical Drawings
    We first consider the copyright titled “Control System Turn Table Schematics: Design
    3,” i.e., the technical drawings. We hold that although physical copying may have occurred, 6 the
    basis for RJ Control and Rogers’s complaint—that the drawings were copied to reproduce the
    control system contained therein—sounds in patent law rather than copyright. Accordingly, we
    agree with the district court that the manufacture of the control system from the copyrighted
    technical drawing was not copyright infringement because the recreation of a control system by
    using a copyrighted technical drawing is not “copying” for purposes of the Copyright Act.
    5Courts    consider “copyrightability” in both aspects of the infringement test. Lexmark, 
    387 F.3d at 538
    .
    Here, we address the copyrightability of the copyrights under the second prong to ensure our holding does not
    establish that technical drawings are never protected by copyright. They may be. However, as we hold today, any
    such copyright protection does not extend to the use of such drawings to construct the object or process contained
    within those drawings. Patent law provides the appropriate protection for such usage.
    6Plaintiffs assert that there is a fact issue regarding whether RSW physically reproduced the technical
    drawings. That may be true, but the question of whether the drawings were themselves reproduced—a separate
    question from whether the drawing was used to create the system portrayed in that drawing—was not clearly raised
    in Plaintiffs’ amended complaint. No facts allude to the physical reproduction of the technical drawings, instead
    alleging only that Defendants used the “Copyright Information” to infringe on “one or more” of Plaintiffs’
    copyrights. Even to the extent this new theory of copyright infringement was raised in Plaintiffs’ response to
    Defendants’ motion for summary judgment, a plaintiff may not expand its claims to assert new theories, either in
    response to summary judgment or on appeal. Bridgeport Music, Inc. v. WM Music Corp., 
    508 F.3d 394
    , 400 (6th
    Cir. 2007). Further, even if we were to consider such copyright infringement of the drawings based on the physical
    reproduction thereof, it is unclear what damages—if any—are attributable to that physical copying.
    No. 20-1009          RJ Control Consultants, Inc., et al. v. Multiject, LLC, et al.       Page 8
    Unlike patent law, “a copyright gives no exclusive right to the art disclosed; protection is
    given only to the expression of the idea—not the idea itself.” Mazer v. Stein, 
    347 U.S. 201
    , 217
    (1954); see also Computer Assocs. Int’l, Inc. v. Altai, Inc., 
    982 F.2d 693
    , 703 (2d Cir. 1992) (“It
    is a fundamental principle of copyright law that a copyright does not protect an idea, but only the
    expression of the idea.”). This distinction between ideas and expression is consistent with the
    distinction between patent and copyright law; copyright law protects an author’s original
    expression but does not give the author the exclusive right to use the ideas expressed in that
    work. Such ideas may only be protected by obtaining a patent. See Nat’l Med. Care, Inc. v.
    Espiritu, 
    284 F. Supp. 2d 424
    , 435 (S.D. W. Va. 2003) (citing Baker v. Selden, 
    101 U.S. 99
    (1879) (“Copyright law protects an author’s original expression, but does not give the author the
    exclusive right to use the ideas expressed in the author’s work. Baker, 101 U.S. at 102. An author
    may only obtain protection for the ideas expressed by obtaining a patent.”). In Baker, the
    plaintiff held a copyright in a book which outlined a bookkeeping system, and the defendant
    created duplicates of forms used within that book. Baker, 101 U.S. at 100. The plaintiff claimed
    that the forms sold by the defendant infringed on the plaintiff’s copyright in the book itself. The
    Supreme Court disagreed, holding that copyright protection extends to the particular expression
    of an art of work, but not to the use of the art of work described in the copyrighted material.
    Baker, 101 U.S. at 100.
    The exclusive right to use the drawings to reconstruct any idea contained therein sounds
    in patent law rather than copyright. In contrast to patent law’s protection of use, copyright
    protection does not “extend to any idea, procedure, process, [or] system . . . , regardless of the
    form in which it is described, explained, illustrated or embodied in such a work.” 
    17 U.S.C. § 102
    (b); see, e.g., Victor Stanley, Inc. v. Creative Pipe, Inc., No. MJG-06-2662, 
    2011 WL 4596043
    , at *3 (D. Md. Sept. 30, 2011) (“[T]o allow the act of manufacturing a non-architectural
    useful item by using a copyright protected drawing of that item to constitute copyright
    infringement would be to elevate the copyright to a patent.”) aff’d, 499 F. App’x 971 (Fed. Cir.
    2013); see also 1 M. Nimmer & D. Nimmer, Nimmer on Copyright § 2.18[A] (“Where the owner
    of a patent obtains the right to exclude others from using the invention, the rights granted to a
    copyright owner under [§] 106 of the Copyright Act do not include the right to prevent others
    from using the copyrighted work.”). A copyright protects the author’s expression but does not
    No. 20-1009               RJ Control Consultants, Inc., et al. v. Multiject, LLC, et al.                        Page 9
    give the author the exclusive right to use the ideas expressed in the author’s work. An author
    may only obtain protection for the ideas expressed by obtaining a patent. Baker, 101 U.S. at
    102. As Defendants note, the Copyright Act may protect a cookbook itself, but that copyright
    protection does not prevent an amateur chef from using the cookbook to prepare a recipe
    contained within that copyrighted book.
    Both the congressional record and case law support the distinction between copyright and
    patent law as it pertains to technical drawings and copyright infringement claims made on the
    basis of using those drawings to create something else. The congressional record preceding the
    enactment of the Copyright Act notes that “[a] copyrighted technical drawing showing the
    construction of a machine, used to manufacture the machine” is not entitled to copyright
    protection to the extent the work “portray[s] a useful article.” Staff of H.R. Comm. on the
    Judiciary, 87th Cong., Rep. of the Register of Copyrights on the General Revision of the U.S.
    Copyright Law (1961). “A ‘useful article’ is an article having an intrinsic utilitarian function
    that is not merely to portray the appearance of the article or to convey information.” 
    17 U.S.C. § 101.7
    In construing this language, courts have routinely held that “the manufacture of a
    machine from a copyrighted technical drawing is clearly not copyright infringement.” Niemi v.
    Am. Axle Mfg. & Holding Inc., No. 05-74210, 
    2006 WL 2077590
    , at *3 (E.D. Mich. July 24,
    2006). Holding a “copyright in a pictorial representation of a useful article does not vest the
    owner of the picture with a derivative copyright in the useful article itself.” Gusler v. Fischer,
    
    580 F. Supp. 2d 309
    , 315 (S.D.N.Y. 2008) (quoting Eliya, Inc. v. Kohl’s Dept. Stores, No. 06 Civ
    195(GEL), 
    2006 WL 2645196
    , at *9 (S.D.N.Y. Sept. 13, 2006)); 
    id.
     (“[The plaintiff] holds a
    copyright in a technical drawing of a useful article, which does not preclude [the] [d]efendants’
    manufacturing . . . of the article itself.”); Espiritu, 
    284 F. Supp. 2d at 433
    , 435–36 (finding that
    7At   least one court has found that technical drawings themselves are not “useful articles” because they are
    created to “convey information” and, thus, are not themselves useful but rather depict useful articles. See, e.g.,
    Oldcaste Precast, Inc. v. Granite Precasting & Concrete, Inc., No. C10-322, 
    2011 WL 813759
    , at *5 (W.D. Wash.
    Mar. 2, 2011). The House Committee Report, however, uses the above example—excluding technical drawings
    from copyright protection—where they portray a useful article, not where they themselves are useful articles. The
    analysis, then, is on whether the depicted item is itself a useful article. The control system itself is a useful article in
    that it is the “brain” used to direct the plastic injection molding and is not designed merely to “convey information.”
    
    17 U.S.C. § 101
    .
    No. 20-1009             RJ Control Consultants, Inc., et al. v. Multiject, LLC, et al.                 Page 10
    copyright protection does not extend to structures built from technical drawings, even where the
    defendant stipulated to using unauthorized copies of the technical drawings).8
    We thus agree with the district court that “the use of the Design 3 drawing to manufacture
    a control system is not an act of copyright infringement.” The copyright protection extends to
    the drawing itself, affording Plaintiffs the exclusive right to prepare derivative works, distribute
    copies, and display the copyright. 
    17 U.S.C. § 106
    . Such protection, however, does not extend
    to the use of those drawings to create the useful article described in those drawings, as patent
    law—with its stricter standards requiring novelty—governs such use protection.                            Mazer,
    
    347 U.S. at 217
    ; see Espiritu, 
    284 F. Supp. 2d at
    434–35. We thus affirm the district court to the
    extent the court found that there was no copyright infringement as to the technical drawings
    themselves.
    B. Software Copyright
    We next consider the software copyright registered as “Control System Turn Table
    Software: Design 3.” In its order granting summary judgment, the district court did not analyze
    the software code, looking instead solely to the copyrightability of the technical drawings. In a
    hearing on Plaintiffs’ motion for reconsideration, however, the court expressed an understanding
    that it still needed to consider the copyrightability of the software code itself. R. 73, PageID
    #2556 (“[T]he problem with my Opinion is I didn’t know what the [software] program was[,]
    and it’s a question of what is the program, whether it’s covered.”). The district court questioned
    whether the court, without an expert, could make an appropriate judgment as to the
    copyrightability of a software program.
    We begin again with the distinction between an unprotectible idea and a protectible
    expression, a distinction which poses “unique problems” when considering computer
    8Plaintiffs cite Nino Homes for the opposite conclusion: that “one may construct a house which is identical
    to a house depicted in copyrighted architectural plans, but one may not directly copy those plans and then use the
    infringing copy to construct the house.” Robert R. Jones Assoc., Inc. v. Nino Homes, 
    858 F.2d 274
    , 280 (6th Cir.
    1988). Courts have repeatedly, however, explicitly declined to extend these architecture cases to non-architectural
    technical drawings, largely because the two categories are covered separately under the Copyright Act. See, e.g.,
    Niemi, 
    2006 WL 2077590
    , at *4 (noting that the holding in Nino Homes is “limited to architectural works”); see also
    Forest River, Inc. v. Heartland Recreational Vehicles LLC, 
    753 F. Supp. 2d 753
    , 759 (N.D. Ind. 2010); Niemi v.
    NHK Spring Co., No. 3:06-CV-1117, 
    2007 WL 2460348
    , at *2 (N.D. Ohio Aug. 27, 2007).

    977 F.2d 1510
    , 1524 (9th Cir. 1992); Mazer,
    
    347 U.S. at 217
    . The 1976 House Report on the Copyright Act applies the statutory limitation in
    § 102(b) directly to computer programs, noting that:
    Some concern has been expressed lest copyright in computer programs should
    extend protection to the methodology or processes adopted by the programmer,
    rather than merely to the “writing” expressing his ideas. Section 102(b) is
    intended, among other things, to make clear that the expression adopted by the
    programmer is the copyrightable element in a computer program, and that the
    actual processes or methods embodied in the program are not within the scope of
    the copyright law.
    Atari Games Corp. v. Nintendo of Am. Inc., 
    975 F.2d 832
    , 838–39 (Fed. Cir. 1992) (quoting
    H.R. Rep. No. 1476, 94th Cong., 2d Sess. 57 (1976), reprinted in 1976 U.S.C.C.A.N. 5659,
    5670).
    In Lexmark, this Court considered this distinction with a software program and noted that
    “the task of separating expression from idea in this setting is a vexing one,” describing the
    distinction between idea and expression as an “elusive boundary line.” Lexmark, 
    387 F.3d at 535
    . To distinguish ideas from expression in the software context, courts have considered two
    doctrines: the doctrine of merger and “scenes a faire.” 
    Id.
     These doctrines are used to filter out
    “unprotectible elements.” See Kohus, 328 F.3d at 856. “Where the expression is essential to the
    statement of the idea . . . the idea and expression are said to have merged. In these instances,
    copyright protection does not exist because granting protection to the expressive component of
    the work necessarily would extend protection to the work’s uncopyrightable ideas as well.”
    Lexmark, 
    387 F.3d at 535
     (internal citations and quotation marks omitted). In other words, if the
    noncopyrightable and copyrightable elements are inextricably intertwined, the noncopyrightable
    aspect trumps the copyrightable one, rendering the entire work uncopyrightable. Murray Hill
    Publ’ns Inc. v. Twentieth Century Fox Film Corp., 
    361 F.3d 312
    , 318 n.2 (6th Cir. 2004)
    (“Of the two principles, that ideas are not protectible and that expressions are protectible, it is the
    former that is the stronger.”).
    Distinguishing between those ideas and expression in the context of software code
    requires a line-by-line understanding of the code, including what specific lines in that code are
    purely functional and whether those unprotectible lines are intertwined with any expressive lines.
    No. 20-1009          RJ Control Consultants, Inc., et al. v. Multiject, LLC, et al.       Page 12
    See Lexmark, 
    387 F.3d at 535
    ; Sega Enters., 977 F.2d at 1524. If there are “many possible ways
    of accomplishing a given task,” then “the programmer’s choice of program structure and design
    may be highly creative and idiosyncratic,” thus pointing in favor of the software—or at least, that
    particular line—being a protectible expression. Sega Enters., 977 F.3d at 1254. On the other
    hand, such computer programs are, “in essence, utilitarian articles” and “[a]s such, they contain
    many logical, structural, and visual display elements that are dictated by the function to be
    performed, by considerations of efficiency, or by external factors such as compatibility
    requirements and industry demands.” Id. Such utilitarian features of the program are not
    protected, and if they are intertwined with any copyrightable elements, the unprotected elements
    trump the protected elements. Lexmark, 
    387 F.3d at 535
    ; Murray Hill, 
    361 F.3d at
    318 n.2.
    The “scenes a faire” doctrine similarly distinguishes between ideas and expression.
    Under this doctrine, certain stock or standard phrases or code lines that “necessarily follow from
    a common theme or setting” are not protected.” Lexmark, 
    387 F.3d at
    535 (citing Gates Rubber
    Co. v. Bando Chem. Indus. Ltd., 
    9 F.3d 823
    , 838 (10th Cir. 1993)). “In the computer software
    context, the doctrine means that the elements of a program dictated by practical realities—e.g.,
    by hardware standards and mechanical specifications, software standards and compatibility
    requirements, computer manufacturer design standards, target industry practices, and standard
    computer programming practices—may not obtain protection.” Id.; Sega Enters., 977 F.2d at
    1524 (“To the extent that a work is functional or factual, it may be copied.”). In considering the
    protectability of a particular copyright under this doctrine, courts may look at “external
    considerations” such as industry standard practices.       Kohus, 328 F.3d at 856.       Where the
    expression is standard or commonplace, then plaintiffs may not claim copyright protection of
    that software. Lexmark, 
    387 F.3d at
    535–36 (citing Brown Bag Software v. Symantec Corp.,
    
    960 F.2d 1465
    , 1473 (9th Cir. 1992) (affirming district court’s finding that “[p]laintiffs may not
    claim copyright protection of an . . . expression that is, if not standard, then commonplace in the
    computer software industry”)).
    In considering these two doctrines, the assistance of an expert is desirable, if not required.
    See Kohus, 328 F.3d at 856 (noting that expert testimony in that case would “likely be required”
    to discern expression from idea under the merger doctrine).           Similarly, we are unable to
    No. 20-1009          RJ Control Consultants, Inc., et al. v. Multiject, LLC, et al.    Page 13
    undertake any analysis under the scenes a faire doctrine without any expert testimony—much
    less without any briefing or argument—regarding standard industry practices regarding control
    systems and the relevant software. See id. at 857–58 (remanding where the “inquiry [into
    copyrightability] will almost certainly require expert testimony, because the drawings are
    technical in nature”). The district court here noted as much but nonetheless denied the motion
    for reconsideration before any such expert was hired or appointed. The technology here is
    complex, as are the questions necessary to establish whether that technology is properly
    protected under the Copyright Act. Which aspects or lines of the software code are functional?
    Which are expressive? Which are commonplace or standard in the industry? Which elements, if
    any, are inextricably intertwined? Without any record evidence—whether expert or not—to
    answer these material questions, there indeed remains a genuine factual dispute. Accordingly,
    we reverse the district court’s grant of summary judgment as to the copyright-infringement claim
    regarding the software copyright, Copyright Registration Number TXu 1-978-284, and remand
    the matter to the district court for the taking of additional evidence.
    Plaintiffs also appeal the district court’s denial of their motion to compel discovery. The
    district court denied that motion as moot. We review denials of motions to compel discovery for
    an abuse of discretion. Louzon v. Ford Motor Co., 
    718 F.3d 556
    , 560 (6th Cir. 2013). To the
    extent the discovery requests are relevant to the surviving claim, i.e. copyright infringement of
    the software, the district court’s denial is vacated. The remaining requests, however—those
    relevant to the technical drawings and the state-law claims—are indeed moot and, as such, the
    district court’s denial of those requests as moot is affirmed.
    IV.
    For the foregoing reasons, we AFFIRM the district court’s grant of summary judgment
    with respect to the copyright infringement claim related to the technical drawings, REVERSE
    the district court’s grant of summary judgment with respect to the copyright infringement claim
    related to the software code, and VACATE IN PART and AFFIRM IN PART the district
    court’s denial of the motion to compel as moot.           We REMAND for further proceedings
    consistent with this opinion.
