    The Honorable Matthew G. Hanson, Judge

    No. 55A05-1709-CT-2168
    Opinion by Chief Justice Rush
    Justices David, Massa, Slaughter, and Goff concur.
    Rush, Chief Justice.
    In Indiana, when an individual is injured by a defectively designed
    product, the Indiana Product Liability Act (IPLA) provides a basis for
    relief. The injured party may bring a defective-design claim against the
    manufacturers of a component part, as well as of the final product.
    Today we address a narrow question regarding an IPLA design-defect
    claim: when does a component-part manufacturer owe no duty, as a
    matter of law, to install safety features that an injured party alleges are
    necessary?
    PACCAR is the manufacturer of a “glider kit,” a component part that
    becomes an operable over-the-road semi-truck after a purchaser installs an
    engine, transmission, and exhaust system. The glider kit has a forty-foot
    blind spot behind it; and it is PACCAR’s standard practice not to include
    certain safety features to mitigate that danger, unless a customer
    specifically requests them.
    Here, a driver backed up a semi with an integrated PACCAR glider kit
    and struck and killed construction foreman Rickey Brewer. His widow
    asserted a design-defect claim against PACCAR, alleging that the lack of
    certain safety features rendered the glider kit defective. PACCAR argued
    that it was entitled to summary judgment because it owed no duty, as a
    matter of law, to install those safety features—because this duty fell solely
    on the final manufacturer of the completed semi.
    Under these circumstances, PACCAR, as the component-part
    manufacturer, is not entitled to summary judgment. Its glider kit was not
    going to be incorporated into an end product that had multiple
    anticipated configurations. Rather, the component part had one
    reasonably foreseeable use: to be integrated into an operable over-the-
    road semi. Thus, PACCAR had to make one of two showings to be
    relieved of a duty, as a matter of law, to include the allegedly necessary
    safety features. It made neither.
    PACCAR did not show that the final manufacturer was offered, and
    declined, the allegedly necessary safety features or that the integrated
    Indiana Supreme Court | Case No. 18S-CT-451 | June 17, 2019         Page 2 of 16
    glider kit can be used safely without them. Thus, whether PACCAR owed
    Brewer a duty to include the features is a question for the trier of fact.
    Finally, while PACCAR may assert a sophisticated-user defense against
    the design-defect claim, the merits of that defense are likewise a question
    for the trier of fact. We accordingly reverse the trial court’s grant of
    summary judgment for PACCAR.
    Facts and Procedural History
    PACCAR manufactures vehicles and parts that W&W Transport uses to
    conduct its trucking operations. One PACCAR product that W&W
    purchases is a glider kit—the body and frame of a semi-truck. W&W
    purchases glider kits, as opposed to new vehicles, so that it can install its
    preferred engines, producing more fuel-efficient semis that are easier to
    maintain.
    In 2015, W&W bought a PACCAR sleeper-cab glider kit, and installed
    an engine, transmission, and exhaust system, rendering the glider kit an
    operable over-the-road semi-truck.
    The glider kit created a forty-foot blind spot directly behind the semi.
    But PACCAR did not include certain safety features—such as a rear-view
    window, a backup alarm, a backup camera, or backup flashers—to
    alleviate the dangers associated with the blind spot when the semi is
    reversed. And PACCAR and W&W disagree about whether PACCAR
    offered these features as options.
    The following year, W&W employee Raymond Miller was backing up
    the completed semi at a construction site. He felt a nudge, which is
    normally “nothing unusual.” But he was immediately alerted by a man
    pounding on his window, urging him to pull forward. Construction
    foreman Rickey Brewer had been pinned between the back of the truck
    and a trailer and died from his injuries.
    Indiana Supreme Court | Case No. 18S-CT-451 | June 17, 2019        Page 3 of 16
    Rickey’s widow, Angela Brewer, filed a wrongful-death lawsuit against
    PACCAR. She asserted, in part, a defective-design claim under the IPLA, 1
    alleging that PACCAR’s glider kit was unreasonably dangerous and
    defective because it lacked certain safety features and warnings relating to
    the blind spot.
    PACCAR moved for summary judgment, arguing that it had no duty,
    as a matter of law, to install those safety features. To that end, PACCAR
    argued that it did not manufacture the completed semi and that the glider
    kit was not defective or unreasonably dangerous when it left PACCAR’s
    control. In support, PACCAR included two affidavits from one of its
    engineers, who stated that safety features were options for buyers to
    order, and that PACCAR built the glider kit to W&W’s design
    specifications.
    In response, Brewer argued that summary judgment was
    inappropriate. She reasoned that there was evidence the glider kit was
    defective under the IPLA because it lacked a rear-view window, a backup
    alarm, a backup camera, backup flashers, and warnings relating to the
    blind spot. In support, she designated evidence including testimony and a
    report prepared by an expert in auto-safety design. The expert opined that
    the glider kit was defectively designed and unreasonably dangerous
    because it lacked adequate backup safety devices as standard
    installations. 2
    The trial court held a hearing on both PACCAR’s motion for summary
    judgment and Brewer’s later cross-motion for partial summary judgment.
    Brewer argued in her cross-motion that under the IPLA, PACCAR owed a
    1Brewer also filed suit against W&W, Miller, and Indianapolis Power & Light—the latter
    owned the site where the accident took place. Brewer settled with W&W and Miller, and IPL
    prevailed on its unopposed motion for summary judgment, leaving PACCAR the only
    remaining defendant.
    2Although it appears that the auto-design expert analyzed the completed semi involved in the
    accident, the alleged safety defects relate specifically to the glider kit’s design and its lack of
    certain safety features.
    Indiana Supreme Court | Case No. 18S-CT-451 | June 17, 2019                            Page 4 of 16
    duty to Rickey as a bystander. The court granted PACCAR’s motion for
    summary judgment and denied Brewer’s cross-motion. Brewer appealed.
    The Court of Appeals reversed. It first held that summary judgment in
    PACCAR’s favor was improper because “it should be a question of fact as
    to whether it was reasonable for PACCAR to put a product into the
    stream of commerce that lacked one or several” safety features. Brewer v.
    PACCAR, Inc., 
    98 N.E.3d 83
    , 93 (Ind. Ct. App.), aff’d on reh’g, 
    104 N.E.3d 625
    (Ind. Ct. App. 2018). It then addressed Brewer’s cross-motion for
    partial summary judgment, explaining “there should be no dispute that
    the IPLA applies to [Brewer’s] claims against PACCAR.” 
    Id. at 97.
    PACCAR petitioned to transfer, which we granted, vacating the Court
    of Appeals opinion. Ind. Appellate Rule 58(A). 3
    Standard of Review
    We review summary judgment de novo, drawing all reasonable
    inferences in Brewer’s favor. See Siner v. Kindred Hosp. Ltd. P’ship, 
    51 N.E.3d 1184
    , 1187 (Ind. 2016). The standard is the same on appeal as it is
    for the trial court: summary judgment is appropriate only when the
    designated evidence “shows that there is no genuine issue as to any
    material fact and that the moving party is entitled to a judgment as a
    matter of law.” Ind. Trial Rule 56(C).
    Discussion and Decision
    The IPLA subjects a manufacturer of “a product or a component part
    of a product,” Ind. Code § 34-6-2-77 (2018) (emphasis added), to liability
    for physical harm caused by a manufacturer placing “into the stream of
    commerce any product in a defective condition unreasonably dangerous
    to any user or consumer,” I.C. § 34-20-2-1. See also I.C. § 34-20-1-1. A
    3We summarily affirm the portion of the Court of Appeals opinion that addresses whether
    the IPLA applies to Brewer’s claims against PACCAR. See App. R. 58(A)(2).
    Indiana Supreme Court | Case No. 18S-CT-451 | June 17, 2019                    Page 5 of 16
    product may be defective under the IPLA if it is defectively designed, if it
    has a manufacturing flaw, or if it lacks adequate warnings about dangers
    associated with its use. See I.C. §§ 34-20-4-1, -2; see also, e.g., Campbell
    Hausfeld/Scott Fetzer Co. v. Johnson, 
    109 N.E.3d 953
    , 956 (Ind. 2018).
    Here, Brewer’s IPLA claim asserts that PACCAR’s glider kit was
    defectively designed because it lacked certain safety features to reduce the
    danger inherent in its forty-foot blind spot. Because a design-defect claim
    is based in negligence, Brewer must establish that (1) PACCAR owed a
    duty to Rickey; (2) PACCAR breached that duty; and (3) the breach
    proximately caused an injury to Rickey. See I.C. § 34-20-2-2; Ford Motor Co.
    v. Rushford, 
    868 N.E.2d 806
    , 810 (Ind. 2007). The only element at issue
    today is duty—whether PACCAR lacked a duty, as a matter of law, to
    install certain safety features. See Kennedy v. Guess, Inc., 
    806 N.E.2d 776
    ,
    783 (Ind. 2004).
    PACCAR acknowledges that component-part manufacturers may be
    liable for negligence under the IPLA—but it asserts that summary
    judgment is appropriate here because it had no duty, as a matter of law, to
    include the safety features that Brewer alleges were necessary. Brewer
    counters that summary judgment in PACCAR’s favor is improper because
    the designated evidence shows the glider kit was defective when it left
    PACCAR’s control—given PACCAR’s failure to include certain safety
    features.
    Indiana caselaw on this issue—when a component-part manufacturer
    has a duty under the IPLA to include safety features—is sparse. But it has
    established that, under the IPLA, component-part manufacturers may
    have no duty, as a matter of law, to install safety features when the
    component part can be put to a variety of uses that prevent the component
    manufacturer from reasonably knowing whether and how safety features
    should be included. See Shanks v. A.F.E. Indus., 
    275 Ind. 241
    , 249–50, 
    416 N.E.2d 833
    , 838 (1981); Del Signore v. Asphalt Drum Mixers, 
    182 F. Supp. 2d 730
    , 745–46 (N.D. Ind. 2002) (applying Indiana law). In those cases, the
    duty to install safety features, if it exists at all, falls on the final
    manufacturer and not the component-part manufacturer. See 
    Shanks, 275 Ind. at 250
    –51, 416 N.E.2d at 838; Del 
    Signore, 182 F. Supp. 2d at 745
    –46.
    Indiana Supreme Court | Case No. 18S-CT-451 | June 17, 2019           Page 6 of 16
    But here, PACCAR’s glider kit is a component with only one
    reasonably foreseeable use: to be integrated into an operable over-the-
    road semi-truck. And Brewer has alleged that the lack of certain safety
    features rendered the component part defective for this use. This Court
    has not yet addressed whether, under these circumstances, a component-
    part manufacturer has no duty, as a matter of law, to install features
    necessary for safe use of the end product.
    Today we hold that, under the IPLA, a manufacturer who produces a
    component part with only one reasonably foreseeable use has no duty, as
    a matter of law, to install safety features if: (1) the final manufacturer was
    offered the safety features and declined them; or (2) the component part,
    once integrated, can be used safely without those safety features.
    Because PACCAR has failed to establish the absence of a genuine issue
    of material fact for either condition, it is not entitled to summary
    judgment. 4 But, as we explain in more detail below, PACCAR may assert
    a sophisticated-user defense for the trier of fact to consider.
    I. In Indiana, component-part manufacturers may have a
    duty to include safety features under certain
    circumstances.
    The IPLA establishes when a product is defective, including in design.
    Indiana Code section 34-20-4-1 provides,
    4 Brewer also asserted a failure-to-warn claim. Because the trial court granted summary
    judgment in PACCAR’s favor “on all claims asserted against PACCAR,” its order applied to
    both the design-defect claim and the failure-to-warn claim. For two reasons, we also reverse
    summary judgment on the failure-to-warn claim. First, to the extent any duty PACCAR has to
    warn overlaps with a duty to include certain safety features, the inappropriateness of
    summary judgment on the design-defect claim makes summary judgment also inappropriate
    on the failure-to-warn claim. See Fleck v. KDI Sylvan Pools, Inc., 
    981 F.2d 107
    (3d Cir. 1992).
    Second, to the extent any duty to warn is distinct from a design-defect duty, PACCAR failed
    to develop a separate argument for the failure-to-warn claim. See T.R. 56(C); 
    Siner, 51 N.E.3d at 1187
    ; 
    Kennedy, 806 N.E.2d at 782
    .
    Indiana Supreme Court | Case No. 18S-CT-451 | June 17, 2019                        Page 7 of 16
    A product is in a defective condition . . . if, at the time it is
    conveyed by the seller to another party, it is in a condition:
    (1) not contemplated by reasonable persons among those
    considered expected users or consumers of the product; and
    (2) that will be unreasonably dangerous to the expected user or
    consumer when used in reasonably expectable ways of
    handling or consumption.
    The IPLA does not differentiate between a final manufacturer and a
    component-part manufacturer. See TRW Vehicle Safety Sys. v. Moore, 
    936 N.E.2d 201
    , 215 (Ind. 2010). Both are “manufacturers” for purposes of the
    IPLA, see I.C. § 34-6-2-77, and so both have a duty “to design . . . products
    which are reasonably fit and safe for the purpose for which they are
    intended,” Guerrero v. Allison Engine Co., 
    725 N.E.2d 479
    , 482 (Ind. Ct.
    App. 2000) (quoting Liberty Mut. Ins. v. Rich Ladder Co., 
    441 N.E.2d 996
    , 999
    (Ind. Ct. App. 1982)).
    PACCAR acknowledges this general duty imposed by the IPLA on
    component-part manufacturers. But PACCAR contends that it had no
    duty, as a matter of law, to install certain safety features because that duty
    fell on the final manufacturer alone.
    We recognize that when a component part is integrated into an end
    product that has multiple anticipated configurations, a component-part
    manufacturer may have no duty, as a matter of law, to install safety
    features. But those are not the circumstances here. The designated
    evidence confirms that PACCAR’s component part—the glider kit—has
    one reasonably foreseeable use. And PACCAR has failed to show that it
    offered, and W&W rejected, the allegedly necessary safety features or that
    the integrated glider kit can be used safely without them. Rather,
    questions of material fact remain on these issues, making summary
    judgment in favor of PACCAR inappropriate.
    Indiana Supreme Court | Case No. 18S-CT-451 | June 17, 2019          Page 8 of 16
    A. Component-part manufacturers have no duty under the
    IPLA to install safety features when it is foreseeable that the
    final manufacturer will put the component to different uses
    depending on how it integrates the component into the final
    product—but this is not the case here.
    There is little Indiana caselaw regarding a component-part
    manufacturer’s duty to include safety features on its component part.
    However, two decisions explain situations in which a component
    manufacturer does not have this legal duty under the IPLA.
    In Shanks v. A.F.E., a component part was intended for use in an
    intricate operation that “could have taken many forms, depending on the
    needs of the owner and the imagination of the 
    designer.” 275 Ind. at 249
    ,
    416 N.E.2d at 838. This Court held that the component-part manufacturer
    had no duty to install additional safety features because it could not know
    “the specific context in which such warning devices could or should be
    used.” 
    Id. at 250,
    416 N.E.2d at 838.
    Similarly, in Del Signore v. Asphalt Drum Mixers, the district court
    concluded that a component-part manufacturer had no way of knowing
    how the owner of an asphalt-producing complex would use the
    component 
    part. 182 F. Supp. 2d at 746
    . The court pointed out that the
    facility could have taken many forms depending on the owner’s specific
    needs. 
    Id. at 745–46.
    Because the component manufacturer could not know
    “how safety features should have been incorporated into [the] complex,”
    the court held that the duty to install any safety features fell solely on the
    owner of the facility. 
    Id. at 746.
    These decisions reveal that a component-part manufacturer has no duty
    under the IPLA to include safety features when three conditions are met:
    (1) the end product has multiple anticipated configurations, (2) the end
    manufacturer determines which configuration the product takes, and (3)
    the different anticipated configurations prevent the component-part
    manufacturer from reasonably knowing whether and how safety features
    should be included with the part.
    Indiana Supreme Court | Case No. 18S-CT-451 | June 17, 2019         Page 9 of 16
    Here, however, PACCAR has pointed to no anticipated end
    configuration that prevented it from reasonably knowing whether certain
    safety features related to the inevitable forty-foot blind spot should be
    included. The designated evidence indisputably shows that PACCAR’s
    sleeper-cab glider kit has one reasonably foreseeable use—to be combined
    with an engine, transmission, and exhaust system into an over-the-road
    semi. And there is no reasonable dispute that an over-the-road semi with
    a sleeper cab is, at some point, going to be used in reverse, and that the
    glider kit—both as supplied and as integrated—has a forty-foot blind
    spot. So unlike in Shanks and Del Signore, here multiple anticipated end
    configurations do not leave the component-part manufacturer without a
    duty, as a matter of law, to include safety features necessary to adequately
    abate inherent dangers.
    But this does not mean that a manufacturer of a component part with
    one reasonably foreseeable use will necessarily owe a duty, as a matter of
    law, to include allegedly necessary safety features. Rather, the component-
    part manufacturer has two paths to relieve itself of such a duty. We
    examine those in detail below, applying them to the facts before us.
    B. Component-part manufacturers have no duty under the
    IPLA to install safety features if they make one of two
    showings; PACCAR has made neither.
    Existing precedent does not squarely address a component-part
    manufacturer’s duty to install safety features when the part has one
    reasonably foreseeable use. But we find instructive both federal caselaw
    and section 5 of the Restatement (Third) of Torts: Products Liability—
    commonly referred to as the “component parts doctrine,” see Davis v.
    Komatsu Am. Indus., 
    42 S.W.3d 34
    , 38 & n.6 (Tenn. 2001). Drawing from
    these sources, we conclude that a component-part manufacturer will have
    no duty, as a matter of law, to install safety features if it makes one of two
    showings: (1) the safety features were offered to, and declined by, the final
    manufacturer or (2) the integrated product can be used safely without the
    allegedly necessary safety features. Here, PACCAR has failed to make
    either showing.
    Indiana Supreme Court | Case No. 18S-CT-451 | June 17, 2019        Page 10 of 16
    1. Under the IPLA, component-part manufacturers have no
    duty to install safety features if the final manufacturer
    was offered, and declined, the features.
    In Anderson v. P.A. Radocy & Sons, Inc., an electrician was fatally
    electrocuted while standing inside a metal basket that was attached to a
    crane. 
    865 F. Supp. 522
    , 526 (N.D. Ind. 1994) (applying Indiana law), aff’d,
    
    67 F.3d 619
    (7th Cir. 1995). An IPLA claim against the component-part
    manufacturer of the metal basket alleged in part that the manufacturer
    should have provided a bucket with insulating material—such as
    fiberglass—to reduce the risk of electrocution. 
    Id. at 526,
    530–31. The
    district court disagreed, noting that the electrician’s employer had the
    option of purchasing a fiberglass bucket from the component-part
    manufacturer, but chose not to. 
    Id. at 531.
    The court held that “a party
    cannot be liable for failing to equip its products with an optional device
    that . . . [was] knowingly rejected.” 
    Id. We agree.
    When safety features are offered, the final manufacturer is in
    the best position to decide which features are necessary—and which are
    not—for the environment in which the integrated product will be used.
    See Parks v. Ariens Co., 
    829 F.3d 655
    , 657–58 (8th Cir. 2016) (collecting
    cases). And so, we hold that under the IPLA, a component-part
    manufacturer has no duty to include optional safety features that were
    offered to, and rejected by, the final manufacturer.
    Here, however, PACCAR has not shown the absence of a material
    factual dispute that it offered, and W&W rejected, the alleged necessary
    safety features. It is true that PACCAR designated evidence from one of
    its engineers that W&W did not choose the optional rear window or
    backup alarm, and that a rear-view camera was incompatible with the
    glider kit because of the engine W&W installed. But it also designated
    W&W’s response to a request for admissions, in which W&W “denies that
    it was provided with a list of options from which to identify or select the
    options that i[t] desired.” PACCAR did not provide anything to refute
    W&W’s response, such as a purchase order or invoice identifying specific
    safety features that were offered and rejected.
    Indiana Supreme Court | Case No. 18S-CT-451 | June 17, 2019        Page 11 of 16
    Thus, PACCAR has not established that it had no duty, as a matter of
    law, to install safety features based on a showing that W&W declined
    those features.
    2. Under the IPLA, component-part manufacturers have no
    duty to install safety features if the part is safe for its
    reasonably foreseeable use without the features.
    Comments to the Restatement (Third) of Torts: Product Liability § 5(a)
    (Am. Law Inst. 1998), which include supporting caselaw, suggest that
    when a component part has one reasonably foreseeable use, the part’s
    manufacturer will have no duty to install safety features if it establishes
    that the integrated component has safe uses without them. See 
    id. § 5
    reporters’ note to cmt. c. But when a component-part manufacturer fails to
    demonstrate that the integrated component may be safe without safety
    features, “liability may attach.” 
    Id. § 5
    reporters’ note to cmt. b. A federal
    circuit decision explains the underlying reason for this approach.
    In Fleck v. KDI Sylvan Pools, Inc., a man was severely injured when he
    dove headfirst into an above-ground pool. 
    981 F.2d 107
    , 112 (3d Cir. 1992).
    During litigation that followed, the parties disputed whether the pool
    liner was defective because it lacked depth markers and warnings. 
    Id. at 112,
    117.
    The component-part manufacturer argued that it had no duty, as a
    matter of law, to include those safety features “because a replacement
    pool liner is a component part that is later incorporated into a final
    product.” 
    Id. at 117.
    Specifically, it argued that the pool liner is an “inert,
    innocuous thing” that cannot cause damage by itself, but only once it is
    incorporated into the final product. 
    Id. at 118–19.
    The court rejected this argument. It noted that although “the danger
    arises only when incorporated into the pool and filled with water, when
    the danger arises is irrelevant”—rather, the issue was whether the lack of
    safety features and warnings on the pool liner rendered it defective. 
    Id. Because the
    component-part manufacturer “knew that its liner would
    ultimately be incorporated into a pool, and nothing else, it [could] then
    Indiana Supreme Court | Case No. 18S-CT-451 | June 17, 2019           Page 12 of 16
    reasonably foresee the potential risk” of failing to include certain features
    that would mitigate the danger. 
    Id. at 118.
    Since the component-part
    manufacturer could foresee that risk, it was not relieved of its duty to
    include those safety features. 
    Id. at 118–19.
    Thus, Fleck explains that if a manufacturer of a component part with
    one anticipated use can reasonably predict that the lack of safety features
    leaves the final product dangerous, then the manufacturer may not escape
    a duty, as a matter of law, to include the features. But what logically
    follows from that principle is the following: if a component-part
    manufacturer cannot reasonably predict the risk of omitting safety
    features to mitigate the danger of the part’s anticipated use, then it should
    be relieved of a duty, as a matter of law, to include those features. And a
    component-part manufacturer can demonstrate its inability to reasonably
    predict such a risk by making the following showing: that its part—once
    integrated for its anticipated use—can be used safely without the
    allegedly necessary safety features. This showing would relieve the
    component-part manufacturer of a duty under the IPLA, as a matter of
    law, to include allegedly necessary safety features.
    Here, PACCAR failed to show the absence of a genuine issue of
    material fact that the glider kit, once built out as an operable semi, can be
    used safely without the allegedly necessary safety features. We recognize
    that PACCAR cites standards from the Mine Safety and Health
    Administration to support its assertion that “[i]n certain applications and
    environments, backup alarms are disfavored because people nearby can
    become de-sensitized to the sound.” But this evidence relates to only one
    safety feature—backup alarms. Brewer has alleged that other features
    should have been included. And the fact that one specific kind of safety
    feature may be ineffective does not mean that the component-part
    manufacturer must have no duty, as a matter of law, to include others.
    We further recognize PACCAR’s designated evidence that a spotter
    should have been in place on the day of the accident to guide the driver as
    he reversed the semi. While this may be true, it does not establish that a
    spotter alone could make the integrated glider kit’s use—without other
    safety features—safe.
    Indiana Supreme Court | Case No. 18S-CT-451 | June 17, 2019         Page 13 of 16
    Thus, PACCAR has not established that it has no duty, as a matter of
    law, to include the safety features Brewer alleges are necessary for the
    glider kit’s reasonably foreseeable use.
    II. The sophisticated-user defense applies to IPLA
    defective-design claims for a lack of safety features.
    Last, we address a defense PACCAR has implicitly raised to challenge
    Brewer’s design-defect claim: the sophisticated-user defense. Until now,
    IPLA caselaw has addressed this defense only in connection with
    inadequate-warning claims. See, e.g., Smock Materials Handling Co. v. Kerr,
    
    719 N.E.2d 396
    , 401, 403 (Ind. Ct. App. 1999); Nat. Gas Odorizing, Inc. v.
    Downs, 
    685 N.E.2d 155
    , 162–64 (Ind. Ct. App. 1997), trans. denied.
    The sophisticated-user defense typically exempts a manufacturer from
    providing warnings about a product’s potential dangers when the users of
    the product are—or should be—already aware of them. See Nat. Gas
    
    Odorizing, 685 N.E.2d at 163
    . Because this defense focuses on the user’s
    actual or constructive knowledge of the danger, its applicability “is almost
    always a question for the trier of fact.” 
    Id. at 164.
    Today we find that, given certain similarities between inadequate-
    warning claims and design-defect claims, the sophisticated-user defense
    should also be available to challenge design-defect claims.
    Both IPLA claims for inadequate warnings and those for defective
    design are based in negligence. See I.C. § 34-20-2-2. To recover damages, a
    plaintiff asserting either type of claim “must establish that the
    manufacturer or seller failed to exercise reasonable care under the
    circumstances in designing the product or in providing the warnings or
    instructions.” 
    Id. In other
    words, both design-defect claims and
    inadequate-warning claims focus on the reasonableness of the
    manufacturer’s conduct. Accordingly, both types of duty—to design a
    product with adequate safety features and to provide adequate
    warnings—may hinge on a user’s knowledge or level of sophistication.
    Our Court of Appeals provided an excellent list of factors for the trier
    of fact to balance in determining whether a manufacturer has satisfied its
    Indiana Supreme Court | Case No. 18S-CT-451 | June 17, 2019       Page 14 of 16
    duty to warn when raising a sophisticated-user defense. Nat. Gas
    
    Odorizing, 685 N.E.2d at 164
    . Revised to account for design-defect claims
    alleging failure to include safety features, those factors are: the nature,
    complexity, and associated dangers of the integrated product; the dangers
    posed by a lack of safety features; and the user’s ability to include the
    safety features. Cf. 
    id. (listing factors
    tailored to the “sophisticated
    intermediary” variety of the defense). This is not an exhaustive list, and
    each case may present unique circumstances and factors.
    Here, PACCAR has asserted that glider kits are sold to and used by
    “sophisticated purchasers.” PACCAR also refers to W&W as a
    “sophisticated” commercial entity, a “sophisticated” final manufacturer,
    and a “sophisticated” customer. Those allegations essentially assert a
    sophisticated-user defense. But, as stated above, this defense is suited for
    the trier of fact, not for summary judgment. See 
    id. And, so,
    PACCAR can
    make this argument to the trier of fact on Brewer’s claims for defective
    design and for inadequate warnings.
    Conclusion
    PACCAR’s designated evidence fails to establish that it had no duty, as
    a matter of law, to include certain blind-spot safety features on its glider
    kit. We therefore reverse the trial court’s grant of summary judgment to
    PACCAR and remand for proceedings consistent with this opinion.
