¶ 1. The petitioner, Ruben Baez Godoy, seeks review of a published court of appeals decision affirming the circuit court's order dismissing his defective design claims in strict liability and negligence against manufacturers of white lead carbonate pigment.1 The issue presented here is whether the circuit court correctly concluded that Godoy's complaint failed to state a claim of defective design where (1) the product is white lead carbonate pigment; (2) the alleged design defect is the presence of lead; and (3) the defendant manufacturers were manufacturers of white lead carbonate pigment.
¶ 2. We determine that the circuit court correctly concluded that the complaint failed to state claims of defective design. A claim for defective design cannot be maintained here where the presence of lead is the alleged defect in design, and its very presence is a characteristic of the product itself. Without lead, there can be no white lead carbonate pigment. We therefore conclude that the complaint fails to allege a design feature that makes the design of white lead carbonate pigment defective. Accordingly, albeit with some clarification of the rationale, we affirm the court of appeals.2
*101I
¶ 3. This is a review of the circuit court's dismissal of design defect claims. Therefore, all facts and allegations in the complaint are presumed to be true. These facts are primarily taken from Godoy's first amended complaint.3
¶ 4. Ruben Baez Godoy is a minor child who grew up in Milwaukee, Wisconsin. When he was approximately one year old, he lived in an apartment at 1502 West Windlake Avenue. The surfaces of the apartment had been coated with paint containing white lead carbonate pigment.
¶ 5. Beginning in March of 1998 and for the duration of his tenancy, Godoy sustained lead poisoning. The source of the lead poisoning was white lead carbonate pigment derived from painted surfaces, paint chips, paint flakes, and dust containing paint in his apartment.
¶ 6. The defendants in this case include E.I. du Pont de Nemours and Company, Armstrong Containers, the Sherwin-Williams Company, and American Cyanamid (collectively, "manufacturer defendants"). These defendants designed, manufactured, processed, marketed, promoted, supplied, distributed and/or sold white lead carbonate products used as a pigment in paints and coatings for residential use. Godoy alleged that the intended purpose of white lead carbonate pigment was as an ingredient in paint. Godoy is unable *102to identify the particular manufacturer of the white lead carbonate pigment present in the apartment.
¶ 7. Ingesting white lead carbonate pigment, like other products containing lead, can cause severe and permanent injuries including learning disabilities, decreased intelligence, deficits in neurophsychological functioning, coma, seizure, and death. By the second half of the twentieth century, manufacturers and members of the scientific community acknowledged that lead is hazardous to human health and that children could get lead poisoning through exposure to paint containing lead. Godoy alleges that the manufacturer defendants nonetheless promoted the use of white lead carbonate pigment in residential paints, marketing it as a safe product that fostered health and well-being.
¶ 8. Godoy filed suit alleging, among other things, that white lead carbonate pigment is defectively designed and that the defendant manufacturers are liable under theories of strict liability and negligence. Although three of the manufacturer defendants designed and manufactured paint in addition to white lead carbonate pigment, Godoy filed suit against them in the capacity of white lead carbonate pigment manufacturers, not in the capacity of paint manufacturers.4
¶ 9. The manufacturer defendants responded by filing a motion to dismiss the defective design claims. They argued that Godoy did not identify a legally cognizable design defect in white lead carbonate pigment and that, as a result, his complaint failed to state design defect claims upon which relief could be *103granted.5 The circuit court dismissed the design defect claims, concluding that "lead is an inherent characteristic of white lead carbonate," and that white lead carbonate pigment cannot be designed without lead.
¶ 10. Godoy was granted permission to file an interlocutory appeal. The court of appeals affirmed the order of the circuit court, determining that a product cannot be said to be defectively designed when that design is inherent in the nature of the product so that an alternative design would make the product something else. See Godoy ex rel. v. E.I. du Pont de Nemours & Co., 2007 WI App 239, ¶¶ 4, 8, 306 Wis. 2d 226, 743 N.W.2d 159.
¶ 11. In its analysis, the court noted that Wisconsin has neither accepted nor rejected the Restatement (Third) of Torts: Product Liability. Id., ¶ 8. Nonetheless, the opinion stated that the Restatement (Third) could "illumine" its inquiry. Id. The court quoted the definition of design defect from the Restatement (Third), and then applied the facts to that definition. Id. Unlike Wisconsin law, the Restatement (Third) requires proof of a reasonable alternative design in design defect cases. Id. Noting that "there is no 'alternative design' to make white-lead carbonate without using lead," the court concluded that the Restatement (Third) "does not sanction imposing liability on the defendants." Id.
*104II
¶ 12. Whether a complaint states a claim upon which relief can be granted is a question of law, which we review independently of the determinations rendered by the circuit court and the court of appeals. John Doe 1 v. Archdiocese of Milwaukee, 2007 WI 95, ¶ 12, 303 Wis. 2d 34, 734 N.W.2d 827. A motion to dismiss tests the legal sufficiency of the claim. Id. We accept as true both the facts in the complaint and the reasonable inferences that may be drawn from such facts. Id.
¶ 13. We construe the allegations liberally in favor of stating a cause of action. Id. However, legal inferences and unreasonable inferences need not be accepted as true. Id.; Morgan v. Pa. Gen. Ins. Co., 87 Wis. 2d 723, 731, 275 N.W.2d 660 (1979). A claim will not be dismissed as legally insufficient unless it appears certain that the plaintiff cannot recover under any circumstances. John Doe 1, 303 Wis. 2d 34, ¶ 12.
Ill
¶ 14. In order to provide context to our analysis and focus to our inquiry, we initially embark on two threshold areas: (a) an overview of the development of our strict liability jurisprudence; and (b) a determination of the product at issue in this case.
A
¶ 15. Products liability law involves complex and continually evolving concepts regarding a manufacturer's responsibility for providing safe con*105sumer products.6 Less than a century ago, products liability jurisprudence was firmly rooted in contract law, which frustrated recovery for many injured consumers. See generally David G. Owen, The Evolution of Products Liability Law, 26 Rev. Litig. 955 (2007). Manufacturers of defective products could claim lack of 'privity of contract' as a near-absolute defense to liability. Id. at 961-64. By mid-century, courts began to respond to "ever-growing pressure for protection of the consumer." Id. at 966 (quoting Fleming James, Jr., Products Liability, 34 Tex. L. Rev. 44, 44 (1955)). In 1963, the landmark case Greenman v. Yuba Power Products, Inc., 377 P.2d 897 (Cal. 1963), declared that manufacturers of defective products could be held strictly liable in tort.
¶ 16. Shortly thereafter, the American Law Institute introduced the Restatement (Second) of Torts, which included for the first time "Special Liability of Seller of Product for Physical Harm to User or Consumer." See Restatement (Second) of Torts § 402A (1965). This section created a new rule of strict liability, holding sellers of defective products liable for defective products even if "the seller has exercised all possible care in the preparation and sale of [the] product." Id. § 402A(2)(a); see also id. cmt. a. The intended effect was to prevent manufacturers, who were in the best position to ensure the quality of their wares, from invoking inapt contract law defenses. Manufacturers could be held strictly liable for a product defect even if they were not negligent. Two years later, Wisconsin embraced *106Section 402A and strict liability7 in Dippel v. Sciano, 37 Wis. 2d 443, 155 N.W.2d 55 (1967).
¶ 17. By the 1990s, some commentators believed that it was necessary to revise the restatement to *107reflect developments in the law. See Owen, supra, at 980. In response, the American Law Institute introduced the Restatement (Third) of Torts: Products Liability in 1998. One major innovation was that the Restatement (Third) split products liability into three distinct categories: manufacturing defects, design defects, and defects based on failure to warn. See Restatement (Third) of Torts: Products Liability § 2 (1998). In defining these categories, the restatement eschewed the doctrinal labels "strict liability" and "negligence." Rather, the restatement defined the categories functionally, according to their required elements of proof. Owen, supra, at 982.
¶ 18. Although we have recognized that the Restatement (Third) may offer new insights into product liability, we have neither adopted nor rejected it in its entirety.8 Haase v. Badger Mining Corp., 2004 WI 97, ¶ 23, 274 Wis. 2d 143, 682 N.W.2d 389. Section 402A of the Restatement (Second) of Torts has remained the touchstone of our analysis for strict products liability.
B
¶ 19. The next threshold area of discussion requires that we pinpoint the product that is the subject of the design defect claims in this case. The identity of the product is essential to an analysis of its design. The circuit court and the court of appeals based their analyses on the design of white lead carbonate pigment, but Godoy argues that the product in question is actually residential paint pigment.
¶ 20. An examination of the complaint, however, undermines Godoy's argument. The complaint alleges that "[t]he white lead carbonate pigment designed ... by *108the Industry Defendants was and is an inherently defective and unreasonably dangerous product." The complaint states that defendant manufacturers are strictly hable because the defect existed "[a]t the time the white lead carbonate left possession and control of the Industry Defendants[.]" The complaint refers to "white lead carbonate," "white lead pigment," or "white lead carbonate pigment" dozens of times.9 The words "residential paint pigment" do not appear in the complaint.
¶ 21. During the review of a motion to dismiss, the allegations in a complaint must be construed liberally in favor of stating a cause of action. John Doe 1, 303 Wis. 2d 34, ¶ 12. Nonetheless, in a products liability case, the plaintiff must — at minimum — identify the product alleged to be defective. Doing so puts the defendant on notice and allows the defendant to begin building a defense. See Midway Motor Lodge of Brookfield v. Hartford Ins. Group, 226 Wis. 2d 23, 35, 593 N.W.2d 852 (Ct. App. 1999) ("[T]he complaint must give the defendant fair notice of not only the plaintiffs claim but the grounds upon which it rests as well." (internal quotations omitted)). A liberal pleading standard cannot transform a complaint regarding "white lead carbonate pigment" into one regarding "residential paint pigment."
¶ 22. Further, in order to advance his claim, the product cannot be residential paint pigment because Godoy is proceeding under the Collins risk-contribution theory. Normally, an injured plaintiff is required to *109identify the particular manufacturer of the product that caused the injury. Collins v. Eli Lilly Co., 116 Wis. 2d 166, 181-82, 342 N.W.2d 37 (1984). Under risk-contribution, however, the plaintiff is not required to identify the specific manufacturer when all similar products are fungible and identically defective. Id. at 180, 194.
¶ 23. We recently applied the risk-contribution theory to white lead carbonate pigment.10 Thomas ex rel. Gramling v. Mallett, 2005 WI 129, 285 Wis. 2d 236, 701 N.W.2d 523. In Thomas, we concluded that for the purposes of risk-contribution, white lead carbonate pigment is fungible, and all manufacturers of white lead carbonate pigment could be held jointly and severally liable for injuries caused by the product. Id., ¶ 27. We have not, however, applied the risk-contribution theory to residential paint pigment.
¶ 24. Nonetheless, Thomas provides little guidance for the issue we address in this case. This case is about defective design claims and Thomas was based on failure to warn claims. The question of whether white lead carbonate pigment was defectively designed was not before the Thomas court. All defective design claims had been dismissed at the circuit court, and that ruling was not appealed. Thomas, 285 Wis. 2d 236, ¶ 181 n.2 (Wilcox, J., dissenting).
¶ 25. Because Godoy cannot identify which defendant produced the defective product that caused his injury, he must proceed under the risk-contribution *110theory. Godoy does not ask us to extend the risk-contribution theory to residential paint pigment. He does not assert that all residential paint pigments are identically defective, which is a prerequisite of risk-contribution. Perhaps he does not assert that all residential paint pigments are identical because he cannot make such an assertion given that not all residential paint pigments contain lead, the alleged defect. Accordingly, based on a review of the complaint, we determine that the product at issue is white lead carbonate pigment.
IV
¶ 26. Having examined these threshold matters, we now address the substantive issue before the court. At issue is the narrow question of whether a complaint alleging strict liability and negligence for a defective design states a claim where (1) the product is white lead carbonate pigment; (2) the alleged design defect is the presence of lead; and (3) the defendant manufacturers were manufacturers of white lead carbonate pigment.
¶ 27. Under Dippel and the Restatement (Second) of Torts, manufacturers of defective products can be liable for the injuries their products cause, regardless of the care taken by the manufacturer or the foreseeability of the harm:
One who sells any product in a defective condition unreasonably dangerous to the user or consumer ... is liable for physical harm ... if:
(a) The seller is engaged in the business of selling such a product, and
(b) It is expected to and does reach the user or consumer without substantial change in the condition in which it is sold.
*111Restatement (Second) of Torts § 402A(1). Section 402A, along with its comments, defines what it means to be defective.
¶ 28. Nonetheless, a determination that a product is defective is not identical to a determination that the product was defectively designed. Put another way, the fact that a defect exists does not compel the conclusion that the source of the defect is the product's design. This distinction makes a difference.
¶ 29. The issue in this case is not whether white lead carbonate pigment is defective, but whether the source of the alleged defect is the product's design. Wisconsin cases have discussed three categories of product defects — manufacturing defects, design defects, and defects based on a failure to adequately warn. A product has a manufacturing defect when it deviates from the manufacturer's specifications, and that deviation causes it to be unreasonably dangerous.11 A product has a design defect when the design itself is the cause of the unreasonable danger.12 Finally, a product is defective based on a failure to adequately warn when an *112intended use of the product is dangerous, but the manufacturer did not provide sufficient warning or instruction.13 Although Section 402A of the Restatement (Second) does not draw clear lines between these types of defects, the comments provide guidance, discussed below.
¶ 30. Godoy's complaint does not identify a particular design feature that is alleged to be defective. However, a fair reading of the complaint suggests that the alleged defect is the presence of lead.14
¶ 31. Lead is a characteristic ingredient of white lead carbonate pigment. By definition, white lead carbonate pigment contains lead. Removing lead from *113white lead carbonate pigment would transform it into a different product. Under these circumstances, we conclude that the design of white lead carbonate pigment is not defective.
¶ 32. An analogy illustrates the distinction. Foil can be made using ingredients other than aluminum— gold, for example — but aluminum foil cannot be made without aluminum. The presence of aluminum is characteristic of aluminum foil. If aluminum posed a hidden danger that the ultimate consumer would not contemplate, a manufacturer might be liable based on the failure to adequately warn or other claims. However, the manufacturer would not be liable based on the design of aluminum foil.
¶ 33. The comments to Section 402A support our conclusion. Comment h lists four potential deficiencies that can result in a defective condition: foreign objects, deterioration before sale, the way in which the product was packaged or prepared, and "harmful ingredients, not characteristic of the product itself." Restatement (Second) of Torts § 402A, cmt. h. It does not state that a defective condition can arise from harmful ingredients that are characteristic of the product. See id. However, if a manufacturer "has reason to anticipate that danger may result from a particular use ... [the manufacturer] may be required to give adequate warning of the danger ... and a product sold without such warning is in a defective condition." Id.; see also id. cmt. j ("In order to prevent the product from being unreasonably dangerous, the [manufacturer] may be required to give directions or warning, on the container, as to its use.").
¶ 34. This distinction is consistent with Wisconsin law. See Green v. Smith & Nephew AHP, Inc., 2001 WI 109, 245 Wis. 2d 772, 629 N.W.2d 727. In Green, the *114plaintiff was a hospital worker who developed a severe allergy to latex. Id., ¶ 1. She brought suit against the manufacturer of latex gloves, alleging a defective design. Id. Notably, the plaintiff did not claim that latex gloves were defective because they contained latex. The presence of latex is "characteristic" of latex gloves. Rather, the plaintiff alleged that they were defective because (1) they contained excessive levels of latex; and (2) they were powdered, which allowed the latex to be airborne. Id., ¶ 11. In effect, she argued that the quantity of latex in the gloves was not characteristic of the product, and that a particular design feature, powder, made the gloves more dangerous.
¶ 35. Godoy argues that the defendants confuse barring a design defect claim based on characteristic ingredients with barring a claim based on the open and obvious danger doctrine. Under the open and obvious danger doctrine, a manufacturer is not liable for injuries when the danger posed by the product should have been apparent to the consumer. See Tanner v. Shoupe, 228 Wis. 2d 357, 367, 596 N.W.2d 805 (Ct. App. 1999) ("In order for a defective design to render a product unreasonably dangerous the defect must be hidden from the ordinary consumer, that is, not an open and obvious defect.").
¶ 36. The doctrine is not applicable in this case. Under the open and obvious danger doctrine, a manufacturer is not strictly liable when a knife cuts flesh, when an alcoholic beverage leads to intoxication, or when the flame on a gas stove burns the chef. See Dippel, 37 Wis. 2d at 459; Greif v. Anheuser-Busch Cos. Inc., 114 F. Supp. 2d 100, 103 (D. Conn. 2000). Further, a Volkswagen driver who has been injured in a car *115accident cannot allege that the car was defectively designed because it was too small — any danger posed by its size should have been readily apparent. Arbet v. Gussarson, 66 Wis. 2d 551, 225 N.W.2d 431 (1975), overruled in part on other grounds by Greiten v. LaDow, 70 Wis. 2d 589, 601 n.1, 235 N.W.2d 677 (1975) (Heffernan, J., concurring). Here, the danger is not readily apparent. Godoy's complaint alleges that the dangerous quality of white lead carbonate pigment is hidden and that the average consumer would not contemplate the risk.15
¶ 37. The circuit court correctly concluded that the complaint failed to state claims of defective design. A claim for defective design cannot be maintained where the presence of lead is the alleged defect in design, and its very presence is a characteristic of the product itself. Without lead, there can be no white lead carbonate pigment. We therefore conclude that the complaint fails to allege a design feature that makes the design of white lead carbonate pigment defective.
V
¶ 38. We have thus determined that Godoy's defective design claims were properly dismissed. However, we recognize that two areas of products liability law *116require further clarification given the arguments advanced by the parties interpreting the analysis of the court of appeals. We take this opportunity to reaffirm that: (a) Wisconsin strict products liability law does not require a plaintiff to prove the feasibility of an alternative design; and (b) the substantial change defense is not a basis of our decision here and was not an alternative basis of the decision of the court of appeals. Substantial change is a fact-intensive inquiry which is generally not appropriate to decide on a motion to dismiss for failure to state a claim. We address these two issues in turn.
A
¶ 39. Godoy argues that the court of appeals' analysis was in error because it relied on the Restatement (Third) of Torts: Products Liability § 2(b), which Wisconsin declined to adopt in Green, 245 Wis. 2d 772, ¶ 74. He asserts that the court of appeals circumvented the consumer contemplation test, the established test for a product defect under Wisconsin law, and instead substituted the Restatement (Third)'s reasonable alternative design requirement.
¶ 40. This court recently reaffirmed that Wisconsin applies the consumer contemplation test to determine whether a product is defective under strict liability. Id., ¶ 35. "Defective," for purposes of the consumer contemplation test, means that the product is "in a condition not contemplated by the ultimate consumer and unreasonably dangerous to that consumer." Id., ¶ 29 (quoting Beacon Bowl, Inc. v. Wis. Elec. Power Co., 176 Wis. 2d 740, 792, 501 N.W.2d 788 (1993)).
*117¶ 41. The term 'defect' is not susceptible to any general definition. Rather, the determination is made on a case-by-case basis relying on the ultimate consumers' expectations. Sumnicht v. Toyota Motor Sales, U.S.A., Inc., 121 Wis. 2d 338, 368, 360 N.W.2d 2 (1984). However, the fact that a defect exists does not compel the conclusion that the source of the defect is the product's design. The question in this case is not whether white lead carbonate pigment is defective, but whether the source of the alleged defect is the product's design.
¶ 42. The court of appeals concluded that the design could not be defective because there is no alternative design to make white lead carbonate pigment without using lead. See Godoy, 306 Wis. 2d 226, ¶ 8 ("[A]s we have seen there is no 'alternative design' to make white-lead carbonate without using lead."). To the extent that the court of appeals relied on a reasonable alternative design requirement, the court's analysis was misguided.
¶ 43. We have explained that although the feasibility of an alternative design can be considered when evaluating a design defect claim, it is not a requirement. Sumnicht, 121 Wis. 2d at 370-71. In Sumnicht, we refused to require a plaintiff to prove that a safer alternative design was commercially available:
A product may be defective and unreasonably dangerous even though there are no alternative, safer designs available.... The question is not whether any other manufacturer has produced a safer design ....
Id. at 371; see also Green, 245 Wis. 2d 772, ¶ 73 (concluding that proof of a reasonable alternative de*118sign would "add[] an additional — and considerable— element of proof' to the analysis.)
¶ 44. Godoy argues that it is inconsistent to reject a reasonable alternative design requirement and still maintain that characteristic ingredients of the product cannot support a claim for defective design. Godoy asserts that our conclusion is analogous to imposing a reasonable alternative design requirement.
¶ 45. Holding that the presence of an ingredient which is "characteristic of the product itself' is an improper basis for a defective design claim is not equivalent to imposing a reasonable alternative design requirement. We do not require that a plaintiff affirmatively prove, through expert testimony, that an alternative design is commercially viable. We do not impose an expensive burden and require a battle of the experts over competing product designs. We simply acknowledge that some ingredients cannot be eliminated from a design without eliminating the product itself. When the ingredient cannot be designed out of the product, the Restatement (Second) instructs that although other claims may be asserted, the proper claim is not design defect.
B
¶ 46. The manufacturer defendants also argue that Godoy cannot recover for a design defect because white lead carbonate pigment is substantially changed when it is integrated into paint. Section 402A states that a product must reach the consumer "without substantial change" in order for the manufacturer to be strictly liable for an injury it causes. Restatement (Second) of Torts § 402A(l)(b). Our cases state that to *119succeed under the substantial change defense, the change must be both substantial and material. Glassey v. Cont'l Ins. Co., 176 Wis. 2d 587, 601, 500 N.W.2d 295 (1993). The purpose of this requirement is to protect a manufacturer from liability when the dangerously defective aspect of the product was altered or introduced after the product left the manufacturer's control.
¶ 47. Defendant manufacturer American Cyanamid asserts that the "substantial change" defense was actually an alternative basis for the court of appeals' decision. We do not find support for this assertion. See Godoy, 306 Wis. 2d 226, ¶ 7.
¶ 48. American Cyanamid cites to the court of appeals' opinion, which provides: "Here, consistent with Shawver, the white-lead carbonate had to be further processed by its integration into paint." Id., ¶ 7. It is a stretch to conclude from this citation that the court of appeals set forth an alternative basis for its dismissal of the plaintiffs complaint based on a substantial change defense.
¶ 49. Likewise, the substantial change defense was not a basis for the circuit court's decision to dismiss Godoy's defective design claims. The defendants' motion to dismiss did not argue that the claims should be dismissed because the white lead carbonate pigment experienced a substantial and material change after leaving the possession and control of the defendant manufacturers. In fact, the circuit court record is devoid of any reference to substantial change.
¶ 50. It is not surprising that substantial change was not discussed at the circuit court. Often, the issue of whether there was a substantial and material change is a fact-intensive inquiry. This type of inquiry may not *120be amenable to resolution on a motion to dismiss where the facts in the complaint are accepted as true.16
¶ 51. In this case, Godoy's first amended complaint alleges that "[t]he white lead carbonate that the Plaintiff was exposed to was in substantially the same condition as it was before leaving the control of the Industry Defendants." The complaint further alleges that "[a]t the time that the white lead carbonate left the possession and control of the Industry Defendants, it was a defective and unreasonably dangerous product[.]"
¶ 52. For purposes of a motion to dismiss, the allegations of the complaint are taken as true and are to be liberally construed in favor of allowing a cause of action to be maintained. John Doe 1, 303 Wis. 2d 34, ¶ 12. Given the procedural posture of this case, we do not address the issue of whether as a matter of law the white lead carbonate pigment underwent a substantial and material change.
¶ 53. Further, we emphasize that our decision here should in no way be interpreted to provide component manufacturers blanket immunity from liability. Integration into another product does not shift responsibility from the manufacturer of a defective component *121to another party "who [is] in no position to detect the hidden defect." City of Franklin v. Badger Ford Truck Sales, Inc., 58 Wis. 2d 641, 649-50, 207 N.W.2d 866 (1973). We have stated:
Where there is no change in the component part itself, but it is merely incorporated into something larger, and where the cause of harm or injury is found, as here, to be a defect in the component part, we hold that, as to the ultimate user or consumer, the strict liability standard applies to the maker and supplier of the defective component part. Where the component part is subject to further processing or substantial change, or where the causing of injury is not directly attributable to defective construction of the component part, the result might be different.
Id. at 649. When component manufacturers introduce defective components into the stream of commerce, they may be held liable for resulting injuries under the particular circumstances of the case.
VI
¶ 54. We determine that the circuit court correctly concluded that the complaint failed to state claims of defective design. A claim for defective design cannot be maintained where the presence of lead is the alleged defect in design, and its very presence is a characteristic of the product itself. Without lead, there can be no white lead carbonate pigment. The complaint fails to allege a design feature that makes the design of white lead carbonate pigment defective. Accordingly, albeit with some modification in the rationale, we affirm the court of appeals.
By the Court. — The decision of the court of appeals is affirmed.
¶ 55. PATIENCE DRAKE ROGGENSACK, J., did not participate.See Godoy ex rel. v. E.I. du Pont de Nemours & Co., 2007 WI App 239, 306 Wis. 2d 226, 743 N.W.2d 159, affirming a non-final order of the circuit court for Milwaukee County, Francis T. Wasielewski, Judge.
Godoy filed suit under theories of strict liability and negligence. Our opinion today addresses only the defective design claims. Other claims remain pending at the circuit court and are not affected by this interlocutory appeal.
The defendant manufacturers filed the motion to dismiss in response to Godoy's first amended complaint. Godoy subsequently filed a second amended complaint adding party defendants. However, the substantive allegations remained unchanged.
American Cyanamid is the only defendant white lead carbonate manufacturer that did not also manufacture paint. For further discussion, see Part III.B below.
In the memorandum in support of the motion to dismiss, the defendants advanced that "[t]o the extent that Plaintiffs claims rest on an allegation of a design defect, they should be dismissed because white lead carbonate is, by definition, made of lead, and can be made no other way.... A design defect claim aimed at a product such as white lead carbonate is not a complaint about a defect in the design of the product. It is, rather, a complaint that it should be a different product altogether."
For an extensive discussion of the history of products liability, see David G. Owen, The Evolution of Products Liability Law, 26 Rev. Litig. 955 (2007) and Richard W. Wright, The Principles of Product Liability, 26 Rev Litig. 1067 (2007).
The Restatement (Second) of Torts § 402A clarified that strict liability "does not preclude liability based upon the alternative ground of negligence of the seller, where such negligence can be proved." Id. cmt. a. Our cases explain that negligence and strict liability are separate avenues of recovery. Morden v. Cont'l AG, 2000 WI 51, ¶ 42, 235 Wis. 2d 325, 611 N.W.2d 659. Both causes of action require a plaintiff to prove that the product causing injury was "defective." See Wis. JI— Civil 3200. However, the elements of negligence and strict liability claims are substantively different. A determination that a manufacturer is strictly liable for a defect is "completely independent of and irrelevant to" a determination that a defect was caused by the manufacturer's negligence. Giese v. Montgomery Ward, Inc., 111 Wis. 2d 392, 414, 331 N.W.2d 585 (1983).
Strict liability is based on Restatement (Second) of Torts § 402A and focuses on the nature of the defendant's product, whereas liability in negligence "hinges in large part on the defendant's conduct under circumstances involving a foreseeable risk of harm." Green v. Smith & Nephew AHP, Inc., 2001 WI 109, ¶ 55, 245 Wis. 2d 772, 629 N.W.2d 727. To prevail under strict liability, a plaintiff must prove that: (1) the product was in a defective condition when it left the possession or control of the seller; (2) it was unreasonably dangerous to the user or consumer; (3) the defect was a cause of the plaintiffs injuries or damages; (4) the seller engaged in the business of selling such a product; and (5) the product was one which the seller expected to and did reach the user or consumer without substantial change in the condition it was in when the seller sold it. Dippel v. Sciano, 37 Wis. 2d 443, 460, 155 N.W.2d 55 (1967).
Here, what is lacking in the strict liability for defective design claim is lacking in the negligent design claim as well. Neither claim alleges a design defect that is not characteristic of the product itself. As such, neither alleges a design feature that makes the design of white lead carbonate pigment defective.
Recently, we stated that the Restatement (Third)'s definition of "defective design" is "fundamentally at odds with current Wisconsin products liability law." Green, 245 Wis. 2d 772, ¶ 72.
The terms "white lead carbonate" or "white lead pigment" are found at least once and sometimes repeatedly in the following paragraphs of the first amended complaint: 9, 11, 12, 13,14,15,16,17,18,19, 20, 21, 25, 26, 27, 28, 30, 36, 37, 38, 39, 41, 42, 44, 46(a), 46(b), 46(c), and 46(d).
In the present case, the court of appeals mistakenly stated that the product in Thomas ex rel. Gramling v. Mallett, 2005 WI 129, 285 Wis. 2d 236, 701 N.W.2d 523, was paint containing white lead carbonate. See Godoy, 306 Wis. 2d 226, ¶¶ 3, 5. This statement misconstrues our holding in Thomas.
See, e.g., City of Franklin v. Badger Ford Truck Sales, Inc., 58 Wis. 2d 641, 648-49, 207 N.W.2d 866 (1973) (affirming a jury verdict that a wheel was defectively constructed because the wheel did not meet manufacturer specifications).
See, e.g., Green, 245 Wis. 2d 772 (concluding that latex gloves were defectively designed because they contained excessive levels of allergy-causing latex proteins, and because they were powdered, which increased the likelihood that the allergenic proteins would be inhaled); Sumnicht v. Toyota Motor Sales, U.S.A., Inc., 121 Wis. 2d 338, 346, 375, 360 N.W.2d 2 (1984) (concluding that a car seat was defectively designed because it was not padded with energy-absorbing material).
See, e.g., Schuh v. Fox River Tractor Co., 63 Wis. 2d 728, 737, 218 N.W.2d 279 (1974) (concluding that a tractor could be unreasonably dangerous and defective when the manufacturer failed to adequately inform the consumer that engaging the clutch would not turn off the fan).
At the hearing on the motion to dismiss, the circuit court asked Godoy's counsel to identify the specific defect in the design of white lead carbonate pigment. Godoy's counsel identified lead. The exchange between Godoy's counsel, Mr. Earle, and the court was set forth in the transcript as follows:
MR. EARLE:... This is a motion to dismiss. There are fact questions about whether or not white lead carbonate is designed in a defective manner.
THE COURT: There is no question that you can't design white lead carbonate without lead, is there?
MR. EARLE: Right.
THE COURT: That is the defect that you are claiming, the harmful defect, that is what makes white lead carbonate dangerous. That is the defect in it, do you agree?
MR. EARLE: I agree.
THE COURT: There is no dispute about any of those facts....
Under Section 402A, manufacturers have an obligation to warn consumers about the hidden dangers of their products. See Restatement (Second) of Torts § 402A cmts. h., i. If the defendant manufacturers had reason to anticipate that white lead carbonate pigment would be dangerous for its intended use, that fact could give rise to a requirement to give adequate warning. Without such warning, white lead carbonate pigment could be considered "defective" under § 402A. These legal and factual questions properly remain pending at the circuit court.
The very cases that American Cyanamid relies upon to advance its argument illustrate this point. It cites to the following cases: Glassey v. Cont'l Ins. Co., 176 Wis. 2d 587, 500 N.W.2d 295 (1993); Haase v. Badger Mining Corp., 2004 WI 97, 274 Wis. 2d 143, 682 N.W.2d 389; Shawver v. Roberts Corporation, 90 Wis. 2d 672, 280 N.W.2d 226 (1979); City of Franklin, 58 Wis. 2d 641; Westphal v. E.I. du Pont De Nemours & Co., 192 Wis. 2d 347, 531 N.W.2d 386 (Ct. App. 1995). None of these cases was decided at a motion to dismiss. With the exception of Westphal, each case had been submitted to a jury. Westphal was decided on summary judgment, after a record had been fully developed through discovery.
