OPINION
_________________
CLAY, Circuit Judge. Plaintiffs Charles Brian and Megan Fox, individually and as
parents and next friends of their minor children Hailey, Matthew, Rebecca, and Sarah Fox,
appeal the district court’s May 30, 2018 order granting summary judgment in favor of Defendant
Amazon.com, Inc. Plaintiffs’ complaint alleges that Defendant (1) sold Plaintiff Megan Fox a
defective or unreasonably dangerous product, in violation of the Tennessee Products Liability
Act of 1978, Tenn. Code Ann. § 29-28-101 et seq., (2) breached a duty to warn Plaintiff Megan
Fox about the defective or unreasonably dangerous nature of that product, in violation of
Tennessee tort law, and (3) caused Plaintiff Megan Fox confusion or misunderstanding about the
source of that product, in violation of the Tennessee Consumer Protection Act of 1977, Tenn.
Code Ann. § 47-18-101 et seq. For the reasons set forth below, we AFFIRM IN PART and
REVERSE IN PART the district court’s summary judgment order.
BACKGROUND
Factual Background
Plaintiffs are a family of six that resides in Davidson County, Tennessee. Defendant is a
corporation that operates a worldwide online marketplace. Defendant’s marketplace facilitates
the sale of products from sellers, including both Defendant and third-party sellers, to buyers.1
W2M Trading Corp. (“W2M”) is a corporation that at one time was a third-party seller that
utilized Defendant’s marketplace to sell hoverboards.
1There has been significant disagreement over how to characterize sellers, other than Defendant, that utilize
Defendant’s marketplace. Plaintiffs characterize them as “co-sellers.” Defendant characterizes them as “third-party
sellers.” And the district court characterized them as “sellers.” We refer to such sellers as “third-party sellers”
because that term accurately and appropriately reflects the fact that they are sellers, other than Defendant, that
utilize Defendant’s marketplace. See Hart v. Amazon.com, Inc., 845 F.3d 802, 803 (7th Cir. 2017) (referring to
“third-party sellers”); Nicosia v. Amazon.com, Inc., 834 F.3d 220, 234 n.4 (2d Cir. 2016) (referring to “third-party
sellers”); Multi Time Machine, Inc. v. Amazon.com, Inc., 804 F.3d 930, 933 (8th Cir. 2015) (referring to “third-party
sellers”).

No. 18-5661 Fox, et al. v. Amazon.com, Inc. Page 3
In November 2015, Defendant’s marketplace contained a webpage offering for sale a
FITURBO F1 hoverboard. The webpage contained, among other things, the purchase price,
$274.79, and a detailed product description, including that the hoverboard was equipped with an
“original Samsung advanced battery pack.” (RE 150, PageID # 2117.)2 Defendant did not set
the purchase price or develop any of the product-related content that appeared on the webpage.
On November 3, 2015, Plaintiff Megan Fox accessed the webpage and purchased a
FITURBO F1 hoverboard. At that time, Plaintiff believed that Defendant owned the hoverboard,
and that she purchased the hoverboard from Defendant. However, Defendant’s records show
that W2M owned the hoverboard, and that Plaintiff purchased the hoverboard from W2M. For
instance, Plaintiff’s order history lists the hoverboard’s “[s]eller of record” as “W2M Trading
Corp.”3 (RE 120, PageID # 1566.) Neither Defendant nor W2M manufactured the hoverboard;
the manufacturer remains unknown.
Plaintiff Megan Fox paid the purchase price to Defendant, and the purchase receipt was
sent from “amazon.com” to Plaintiff’s email address. (RE 161, PageID # 2205.) The receipt
contained various details about the purchase, including the order date, the shipment date, the
shipping address, and the billing address. The receipt also contained the phrase, “Sold
by: -DEAL-.” (Id.)
Defendant operates a program known as “Fulfillment by Amazon” (“FBA”), through
which third-party sellers can opt to use storage and shipping services offered by Defendant. If a
third-party seller participates in FBA, its products are stored in an Amazon Fulfillment Center
until they are purchased, at which point Defendant ships the products to the buyers. Participants
in FBA pay a fee to Defendant for these services, but retain title to their products.
The parties disagree over whether W2M participated in FBA, and accordingly over
whether W2M or Defendant stored and shipped the hoverboard purchased by Plaintiff Megan
2Except as otherwise indicated, record citations refer to the record in district court action No. 16-cv-03013.
3Plaintiff’s order history also states that the hoverboard was “[s]old by: W-Deals,” and that the “[s]eller
name” was “W-Deals.” (RE 120, PageID # 1566.) W2M chose the name “W-Deals,” as well as the
name “-DEAL-,” pursuant to Defendant’s policy permitting third-party sellers to choose “friendly names” by which
they could be identified as a seller of their products. (RE 119-1, PageID # 1500.)

Fox. Defendant’s records show that, in 2015, W2M participated in FBA for some of the
products it sold on Defendant’s marketplace. Additionally, the hoverboard purchased by
Plaintiff was shipped from China via Federal Express, arrived in an Amazon-labeled box, and its
Amazon Standard Identification Number (“ASIN”) was B00WGX04YM. And Defendant’s
records show that, in 2015, Defendant had Amazon Fulfillment Centers in China, shipped items
via Federal Express in Amazon-labeled boxes, and stored a hoverboard with the ASIN
B00WGX04YM. However, Defendant’s records also show that multiple third-party sellers sold
hoverboards with the ASIN B00WGX04YM, and that Plaintiff’s hoverboard was “[f]ulfilled by:
W-Deals.” (RE 120, PageID # 1566.) Plaintiff received the hoverboard sometime between
November 10, 2015 and November 17, 2015.
Defendant requires all third-party sellers that utilize its marketplace to sign Defendant’s
Business Solutions Agreement (“BSA”). The BSA provides in part that third-party sellers are
prohibited from direct communication with buyers. Rather, all communication with buyers
comes from Defendant. The BSA also provides that Defendant retains initial control over
customer payments. Generally, customers pay Defendant, and Defendant then remits those
payments to third-party sellers every 14 days. However, Defendant retains the right to impose a
90-day hold on those payments.
The parties disagree over whether Defendant remitted Plaintiff Megan Fox’s payment to
W2M. Defendant’s records show that from January 1, 2015 through December 31, 2016,
Defendant remitted approximately $1.4 million in customer payments to W2M. However,
Defendant’s records do not show that Plaintiff’s payment specifically was remitted to W2M.
Sometime in November 2015, following news reports of hoverboard fires and explosions,
Defendant began a thorough internal investigation into the dangers posed by hoverboards. That
investigation identified at least 17 complaints of hoverboard fires or explosions in the United
States that involved hoverboards purchased on Defendant’s marketplace. For instance, on
November 30, 2015, a customer sent an email to Defendant’s CEO, Jeff Bezos, informing Bezos
that a hoverboard the customer had purchased had burst into flames while his daughter was
riding it.

No. 18-5661 Fox, et al. v. Amazon.com, Inc. Page 5
Based on the results of the investigation, Damon Jones, Defendant’s product safety
manager, was concerned that the entire product category of hoverboards was “bad.” (RE 117-5,
PageID # 1265.) In his view, “there was no precedent for this kind of event in the product safety
community,” in part because of the “widespread nature of the problem.” (Id. at PageID # 1264–
65.) On December 10, 2015, the results were presented to “a broad set of senior decision-
makers” at Defendant. (Id. at PageID # 1258.) By that time, Damon Jones had removed his own
hoverboard from his home.
On December 11, 2015, Defendant ceased all hoverboard sales worldwide. At that time,
Defendant knew that approximately 250,000 hoverboards had been sold on its marketplace in the
previous 30 days. At that time, Defendant knew that approximately 25% of those hoverboards
had not yet been delivered. Also at that time, Defendant knew that it was likely that a majority
of those hoverboards would remain unopened until the holiday season in late December. As a
result, Defendant made “contingency plans” in anticipation of more fires and explosions,
including scheduling employees to work on December 26, 2015 in order to monitor news reports
and customer complaints about hoverboard fires and explosions. (RE 161, PageID # 2209.)
On December 12, 2015, Defendant sent an email to hoverboard purchasers that
Defendant described as intended to be “non-alarmist” because it would likely be “headline
news.” (Id. at PageID # 2210.) The subject line of the email stated: “Important Product Safety
Notification Regarding your Amazon.com Order.” (RE 117-17, PageID # 1402.) The body of
the email stated: “There have been news reports of safety issues involving products like the one
you purchased that contain rechargeable lithium-ion batteries. As a precaution, we want to share
with you some additional information about lithium-ion batteries and safety tips for using
products that contain them.” (Id.) The email included a link for the “information and safety
tips,” a link “to initiate a return,” and a request that the recipient “pass along this information” to
the proper person if the hoverboard was purchased for someone else. (Id.) The email did not
inform hoverboard purchasers of any of the actions Defendant had taken to evaluate the dangers
posed by hoverboards, including the findings and results of its internal investigation. The email
did not inform hoverboard purchasers that the reported safety issues included a risk of fire and

-- 5 of 18 --

No. 18-5661 Fox, et al. v. Amazon.com, Inc. Page 6
explosion. And the email did not inform hoverboard purchasers that Defendant had ceased all
hoverboard sales worldwide.
The December 12, 2015 email was sent to Plaintiff Megan Fox. Plaintiff does not recall
receiving or reading the email. However, Plaintiff “had a habit” of reading emails sent to her
email address. (RE 161, PageID # 2210.) Plaintiff testified that she would not have let the
hoverboard enter or remain in her home had she known that there had been 17 complaints of
hoverboard fires or explosions in the United States that involved hoverboards purchased on
Defendant’s marketplace, that Defendant anticipated additional complaints during the holiday
season in late December, or that Defendant had ceased all hoverboard sales worldwide.
On January 9, 2015, Matthew Fox was playing with his new hoverboard while the rest of
the family was away from the home. Eventually, he stopped playing with the hoverboard and
left it on the first floor of the family’s two-story home. When Hailey Fox returned to the home,
she sent a text message to Plaintiff Megan Fox stating that she thought that someone had broken
into the home. Plaintiff Megan Fox alerted Plaintiff Charles Brian Fox of Hailey’s message, and
he drove home immediately, accompanied by Sarah and Rebecca Fox. By the time he arrived,
Matthew and Hailey had hidden on the second floor of the home, fearing an intruder.
When Plaintiff Charles Brian Fox arrived, the home was on fire, and Matthew and Hailey
were trapped on the second floor. He frantically searched for a way to enter the home, but the
intensity of the fire prevented him from getting inside. He then heard Hailey banging on a
second-floor window. At his instruction, Hailey broke the window, and jumped out.
He attempted to break her fall. He then heard Matthew banging on another second-floor
window. Again, at his instruction, Matthew broke the window, and jumped out. Plaintiff Megan
Fox arrived shortly thereafter to find that everyone had escaped from the home, but that the fire
was still raging. As a result of the fire, the members of the Fox family suffered various physical
and psychological injuries, and their home, along with virtually all of the personal property
contained therein, was destroyed.
It is undisputed that the fire was caused by the lithium-ion battery in Plaintiff Megan
Fox’s hoverboard.

Procedural History
Plaintiffs filed a complaint in the United States District Court for the Middle District of
Tennessee against Defendant and W2M.4 Plaintiffs’ complaint alleges that Defendant (1) sold
Plaintiff Megan Fox a defective or unreasonably dangerous product, in violation of the
Tennessee Products Liability Act of 1978, Tenn. Code Ann. § 29-28-101 et seq., (2) breached a
duty to warn Plaintiff Megan Fox about the defective or unreasonably dangerous nature of that
product, in violation of Tennessee tort law, and (3) caused Plaintiff Megan Fox confusion or
misunderstanding about the source of that product, in violation of the Tennessee Consumer
Protection Act of 1977, Tenn. Code Ann. § 47-18-101 et seq. (Id.) Following discovery,
Plaintiffs filed a motion for partial summary judgment, and Defendant filed a motion for
summary judgment. On May 30, 2018, the district court granted Defendant’s motion for
summary judgment, reasoning that all of Plaintiffs’ claims failed as a matter of law.
This appeal followed.
DISCUSSION
I. Standard of Review and Applicable Law
We review a district court’s grant of summary judgment de novo, “drawing all reasonable
inferences in favor of the nonmoving party.” Rocheleau v. Elder Living Const., LLC, 814 F.3d
398, 400 (6th Cir. 2016) (quotation omitted). Summary judgment is appropriate where the
movant demonstrates that 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). Accordingly, summary judgment
must be entered where the nonmovant “fails to make a showing sufficient to establish the
existence of an element essential to that party’s case, and on which that party will bear the
burden of proof at trial.” United States v. Storey, 640 F.3d 739, 743 (6th Cir. 2011) (quotation
omitted).
4Plaintiffs have since obtained a default judgment against W2M.

-- 7 of 18 --

No. 18-5661 Fox, et al. v. Amazon.com, Inc. Page 8
Where, as here, our subject matter jurisdiction is based on diversity of citizenship, we
apply the substantive law of the forum state. Berrington v. Wal-Mart Stores, Inc., 696 F.3d 604,
607 (6th Cir. 2012). “Faithful application of a state’s law requires federal courts to ‘anticipate
how the relevant state’s highest court would rule in the case.’” Id. (quotation omitted). Thus, we
are bound by controlling decisions of that court, and in the absence of decisions addressing the
issue, must predict how that court would rule by looking to “all available data.” Id. (quotation
omitted). However, this Court has often warned that “[f]ederal courts should be ‘extremely
cautious about adopting substantive innovation in state law.’” Id. at 608 (quotation omitted).
II. Analysis
A. Plaintiffs’ Tennessee Products Liability Act (“TPLA”) Claim
The TPLA provides that a “manufacturer” or “seller” of a product may be liable for
personal injury or property damage caused by that product if it was “in a defective condition or
unreasonably dangerous at the time it left the control of the manufacturer or seller.” Tenn. Code
Ann. § 29-28-105(a). “Manufacturer” is defined as “the designer, fabricator, producer,
compounder, processor, or assembler of [a] product or its component parts.” Id. § 29-28-102(4).
And “seller” is defined as “any individual or entity engaged in the business of selling a product,”
including a “retailer,” “wholesaler,” or “distributor,” as well as a “lessor” engaged in the
business of leasing a product and a “bailor” engaged in the business of bailment of a product. Id.
§ 29-28-102(7).
At issue in this case is whether Defendant is a “seller” of Plaintiff Megan Fox’s
hoverboard. Defendant argues that it “never had title to the hoverboard” and thus could not sell
it. (Brief for Appellee at 16.) Plaintiffs argue that Defendant “controlled all aspects of the
[hoverboard] sales transaction” and thus effectively sold it. (Brief for Appellants at 20.)
We begin, as we must, with “the natural and ordinary meaning of the language used.” Penley v.
Honda Motor Co., 31 S.W.3d 181, 185 (Tenn. 2000) (quotation omitted).
The TPLA’s definition of “seller” hinges on an individual’s or entity’s engagement “in
the business of selling.” Tenn. Code Ann. § 29-28-102(7). Parsing this phrase, to “sell”
generally means to dispose of property “by sale.” See Sell, Black’s Law Dictionary (4th ed.

-- 8 of 18 --

No. 18-5661 Fox, et al. v. Amazon.com, Inc. Page 9
1968); Sell, Black’s Law Dictionary (10th ed. 2014). A “sale” is generally a transfer of title to or
possession of property for an agreed upon price, or the agreement by which such a transfer takes
place. See Sale, Black’s Law Dictionary (4th ed. 1968); Sale, Black’s Law Dictionary (10th ed.
2014). And to be engaged “in the business of” something generally means to be regularly
engaged in it for livelihood or gain. See Business, Black’s Law Dictionary (4th ed. 1968);
Business, Black’s Law Dictionary (10th ed. 2014); see also Rollins v. Cherokee Warehouses,
Inc., 635 F. Supp. 136, 138 (E.D. Tenn. 1986).
Accordingly, one possible construction of the TPLA’s definition of “seller” is any
individual or entity regularly engaged in transferring title to a product for an agreed upon price,
for livelihood or gain. Defendant argues that we should adopt this construction because it
accords with the Uniform Commercial Code, which Tennessee has adopted in relevant part.
Specifically, the Uniform Commercial Code defines “seller” as “a person who sells or contracts
to sell goods,” and defines “sale” as “the passing of title from the seller to the buyer for a price.”
Tenn. Code Ann. §§ 47-2-103(1)(d), 47-2-106(1).
However, we are not persuaded that the Tennessee legislature intended such a limited
construction. See Spires v. Simpson, 539 S.W.3d 134, 143 (Tenn. 2017) (“The cardinal rule of
statutory construction is to effectuate legislative intent, with all rules of construction being aides
to that end.”). Significantly, the TPLA’s definition of “seller” expressly includes a “lessor” and
a “bailor,” neither of which necessarily transfers title to the products they lease or bail. See, e.g.,
Bailment, Black’s Law Dictionary (10th ed. 2014) (“Unlike a sale or gift of personal property, a
bailment involves a change in possession but not in title.”). Thus, this construction would result
in a definition of “seller” that excludes examples that the legislature explicitly included. And
“[a]n important canon of statutory construction counsels that a statute . . . should be interpreted
to preclude any part from being ‘inoperative, superfluous, void, or insignificant.’” Baker v.
State, 417 S.W.3d 428, 439 n.11 (Tenn. 2013) (quotation omitted).
The Tennessee Supreme Court’s decision in Baker v. Promark Products West, Inc.,
692 S.W.2d 844 (Tenn. 1985) is instructive. In that case, the court held that a TPLA claim for
breach of implied warranty can be maintained against a lessor or bailor of personal property,
notwithstanding the fact that the Uniform Commercial Code provided that the warranty was

-- 9 of 18 --

No. 18-5661 Fox, et al. v. Amazon.com, Inc. Page 10
implied only in certain contracts for “sale.” Id. at 847. The court reasoned that the legislature
“carefully considered who was to be a ‘seller’ in a products liability action,” and that the
legislature’s inclusion of “lessor” and “bailor” in the TPLA’s definition of “seller” demonstrated
its intent “to extend protection for products liability injuries beyond the technical buyer-seller
relationship encompassed by a strict interpretation of the Uniform Commercial Code.” Id.
(emphasis added). Accordingly, the court stated that in a products liability action for breach of
implied warranty, no actual “sale” need occur, whereas “if the action is not a products liability
action . . . an actual ‘sale’ [is] required.” Id.
This Court’s decision in Winningham v. Ciba-Geigy Corp., 156 F.3d 1234 (6th Cir. July
14, 1998) (Table) is similarly instructive. In that case, this Court held that the TPLA’s statute of
repose applies to bailments, notwithstanding the fact that it runs from the date on which the
product was “purchased.” Id. at *3. This Court reasoned that the legislature’s inclusion of
“lessor” and “bailor” in the TPLA’s definition of “seller” demonstrated its intent that the statute
of repose apply regardless of the occurrence of an actual sale. Id. Accordingly, this Court stated
that the plaintiffs’ argument “that no title passed . . . and thus no sale occurred . . . ignore[d] the
definition of the term ‘seller’ in the TPLA.” Id. Thus, it would seem that the TPLA’s definition
of “seller” is not limited to any individual or entity regularly engaged in transferring title to a
product for an agreed upon price, for livelihood or gain.
Another possible construction of the TPLA’s definition of “seller” is any individual or
entity regularly engaged in exercising sufficient control over a product in connection with its
sale, lease, or bailment, for livelihood or gain. Plaintiffs argue that we should adopt this
construction because it accords with the text of the TPLA and Tennessee case law.
Plaintiffs’ argument is persuasive. Unlike the construction urged by Defendant, this
construction is broad enough to include all of the TPLA’s examples of a “seller”—a “retailer,” a
“wholesaler,” a “distributor,” a “lessor,” and a “bailor,” Tenn. Code Ann. § 29-28-102(7)—each
of which exercises a significant degree of control over the products they sell, lease, or bail. This
construction also accords with Tenn. Code. Ann. § 29-28-105(a), the “key operative provision”
of the TPLA, Whitehead v. Toyota Motor Corp., 897 S.W.2d 684, 689 (Tenn. 1995), and with
Tennessee case law. As stated above, § 29-28-105(a) provides that the liability of a

-- 10 of 18 --

No. 18-5661 Fox, et al. v. Amazon.com, Inc. Page 11
“manufacturer” or “seller” is contingent upon whether the product was “in a defective condition
or unreasonably dangerous at the time it left the control of the manufacturer or seller.”
(emphasis added). And in Baker, the Tennessee Supreme Court explained that a TPLA claim for
breach of implied warranty can be maintained “[r]egardless of whether title passes in the
transaction” because “one party to the relationship is in a better position to know and control the
condition of the chattel.” 692 S.W.2d at 848 (emphasis added). Thus, both the legislature and
Tennessee Supreme Court have indicated that control is an important consideration underlying
products liability law.
Moreover, this construction is consistent with the remedial purpose of the TPLA.
“A primary purpose of [the TPLA] is ‘to ensure that an injured consumer may maintain a strict
liability action against whomever is most likely to compensate him for his injuries.’” Owens v.
Truckstops of Am., 915 S.W.2d 420, 432 (Tenn. 1996) (quotation omitted). In furtherance of that
purpose, the TPLA plainly provides that where the manufacturer and others in the chain of
distribution are “not amenable to service of process,” “insolvent,” or unknown, “an injured
consumer can assert liability against [a] ‘faultless’ seller. Id. Otherwise, “the injured consumer
would be left with no remedy.” Id.; see also Baker, 692 S.W.2d at 848.
In this case, Defendant is clearly the entity “most likely to compensate” Plaintiffs for
their injuries. See Owens, 915 S.W.2d at 432. The third-party seller and manufacturer of
Plaintiff Megan Fox’s hoverboard, to whom Plaintiffs might otherwise look for compensation,
appear to be judgment-proof and unknown respectively. And Defendant certainly has the
capacity to compensate Plaintiffs, as it accounts for 49.1% of all online retail spending in the
United States, nearly more than all other online retailers combined, and generated $141.92
billion in product sales in 2018, including $13.38 billion in fees paid by third-party sellers in the
fourth quarter alone.5 The combination of these two facts—Defendant’s ability to facilitate the
sale of goods by sellers who are functionally outside the reach of U.S. courts, and its online retail

No. 18-5661 Fox, et al. v. Amazon.com, Inc. Page 12
dominance—often drastically hinders the ability of consumers injured by defective or
unreasonably dangerous products to receive compensation for their injuries.
Defendant also has the capability to spur the manufacturing and sale of safer products in
the future, which is a primary purpose behind the doctrine of products liability in general. See
Owens, 915 S.W.2d at 432; Baker, 692 S.W.2d at 847. That capability can indeed be seen in
several of the facts of this case. Defendant required W2M to sign its BSA, which imposed
various restrictions on W2M’s ability to sell products on Defendant’s marketplace. Defendant
attempted to demand safety compliance documentation from third-party hoverboard sellers
following initial reports of hoverboard fires and explosions. And Defendant eventually ceased
all hoverboard sales on its marketplace worldwide.
Lastly, we note that courts applying the products liability law of other states have also
considered or adopted constructions of “seller” or other similar terms that hinge on the degree of
control exercised over a product. See, e.g., Erie Ins. Co. v. Amazon.com, Inc., _ F.3d _, No. 18-
1198, 2019 WL 2195146, at *3 (4th Cir. May 22, 2019); Garber v. Amazon.com, Inc., _ F. Supp.
3d _, No.17-C-673, 2019 WL 1437877, at *7 (N.D. Ill. Mar. 31, 2019); Carpenter v.
Amazon.com, Inc., No. 17-03221-JST, 2019 WL 1259158, at *4 (N.D. Cal. Mar. 19, 2019);
Eberhart v. Amazon.com, Inc., 325 F. Supp. 3d 393, 398–99 (S.D.N.Y. 2018); Allstate N.J. Ins.
Co. v. Amazon.com, Inc., No. 17-2738, 2018 WL 3546197, at *7–10 (D.N.J. July 24, 2018);
Oberdorf v. Amazon.com, Inc., 295 F. Supp. 3d 496, 498 (M.D. Pa. 2017); see also Stiner v.
Amazon.com, Inc., 120 N.E.3d 885, 895 (Ohio Ct. App. 2019).
Thus, we hold that the TPLA’s definition of “seller” means any individual regularly
engaged in exercising sufficient control over a product in connection with its sale, lease, or
bailment, for livelihood or gain. We turn next to an application of that definition to the facts of
this case.
Plaintiffs argue that Defendant exercised sufficient control over Plaintiff Megan Fox’s
hoverboard because Defendant (1) stored and shipped the hoverboard, (2) initially obtained the
payment made in exchange for the hoverboard, (3) retained the payment made in exchange for
the hoverboard, and (4) handled all communications with Plaintiff Megan Fox regarding the

No. 18-5661 Fox, et al. v. Amazon.com, Inc. Page 13
hoverboard. However, Plaintiffs’ first and third assertions are belied by the record. Defendant’s
records demonstrate both that the hoverboard was “[f]ulfilled by: W-Deals,” (RE 120, PageID
# 1566.), and that Defendant remitted approximately $1.4 million in customer payments to W2M
between January 1, 2015 and December 31, 2016, a time period which includes Plaintiff Megan
Fox’s hoverboard purchase. Plaintiffs ask us to infer that stray pieces of circumstantial evidence
cast doubt on the accuracy of these records, and stress that this case is at the summary judgment
stage; but summary judgment “does not allow, much less require that we draw strained and
unreasonable inferences in favor of the nonmovant.” Audi AG v. D’Amato, 469 F.3d 534, 545
(6th Cir. 2006) (quotation omitted).
What remains—Plaintiff’s second and fourth assertions—is not a sufficient exercise of
control to be deemed a “seller” under the TPLA. In contrast to those assertions, Defendant did
not choose to offer the hoverboard for sale, did not set the price of the hoverboard, and did not
make any representations about the safety or specifications of the hoverboard on its marketplace.
We also note that courts applying the products liability law of other states to comparable facts
have reached similar conclusions. See, e.g., Garber, 2019 WL 1437877, at *7, *10; Carpenter,
2019 WL 1259158, at *5; Stiner, 120 N.E.3d at 895. At bottom, we are not convinced, on the
record before us, that Defendant exercised sufficient control over Plaintiff Megan Fox’s
hoverboard to be deemed a “seller” of the hoverboard under the TPLA. Thus, we hold that there
is no genuine dispute of material fact regarding Plaintiffs’ TPLA claim, and affirm the district
court’s dismissal.6
B. Plaintiffs’ Tennessee Tort Law Claim
Tennessee tort law provides that an individual can assume a duty to act, and thereby
become subject to the duty of acting reasonably. Grogan v. Uggla, 535 S.W.3d 864, 871 (Tenn.
2017). In evaluating whether such a duty has been assumed, Tennessee courts look to the
Restatement (Second) of Torts §§ 323, 324A. Id. at 873; see also Downs v. Bush, 263 S.W.3d
812, 820 (Tenn. 2008). Section 323 states:
6Accordingly, we need not decide whether the Communications Decency Act, 47 U.S.C § 230, grants
Defendant immunity from Plaintiffs’ TPLA claim.

No. 18-5661 Fox, et al. v. Amazon.com, Inc. Page 14
One who undertakes, gratuitously or for consideration, to render services to
another which he should recognize as necessary for the protection of the other’s
person or things, is subject to the liability to the other for physical harm resulting
from his failure to exercise reasonable care to perform his undertaking, if
(a) his failure to exercise reasonable care increases the risk of such harm, or
(b) the harm is suffered because of the other’s reliance upon the undertaking.
Restatement (Second) of Torts § 323 (emphasis added). And § 324A states:
One who undertakes, gratuitously or for consideration, to render services to
another which he should recognize as necessary for the protection of a third
person or his things, is subject to liability to the third person for physical harm
resulting from his failure to exercise reasonable care to protect his undertaking if
(a) his failure to exercise reasonable care increases the risk of such harm, or
(b) he has undertaken to perform a duty owed by the other to the third person, or
(c) the harm is suffered because of reliance of the other or the third person upon
the undertaking.
Restatement (Second) of Torts § 324A (emphasis added).
Evidently, the rule stated in § 324A “parallels the one stated in § 323.” Grogan,
535 S.W.3d at 873 n.10 (quotation omitted). However, the emphasized references in the
Restatement highlight a crucial difference. Section 323 governs liability to the person to whom
the defendant undertook to render services, while § 324A governs liability to persons other than
the person to whom the defendant undertook to render services. Id.
In this case, Plaintiffs allege that Defendant gratuitously undertook to warn Plaintiff
Megan Fox of the dangers posed by the hoverboard when it sent her the December 12, 2015
email, that Defendant was negligent in that undertaking, and that Defendant’s negligence caused
them harm. The district court held that § 324A was inapplicable to Plaintiffs’ claims because it
“contemplate[d] liability to third parties.” (RE 161, PageID # 2221–22.) And the district court
also held that Plaintiffs forfeited any § 323 claim. The first holding was erroneous, and the
second we need not address.
By its plain terms, § 324A governs liability to persons other than the person to whom the
defendant undertook to render services. Grogan 535 S.W.3d at 872–73 & n.10. For instance, in

-- 14 of 18 --

No. 18-5661 Fox, et al. v. Amazon.com, Inc. Page 15
Biscan v. Brown, the plaintiff argued that the defendant undertook to monitor minors at a party at
which alcohol was served, and that the defendant’s negligent monitoring caused physical harm to
the plaintiff—a motorist who was injured in a car accident with an intoxicated minor who had
attended the party. 160 S.W.3d 462, 483 (Tenn. 2005). Similarly, in this case, Plaintiffs argue
that Defendant undertook to warn Plaintiff Megan Fox when it sent her the December 12, 2015
email, and that Defendant’s negligent warning caused physical harm to the other members of her
family. Accordingly, while Defendant’s liability to Plaintiff Megan Fox is properly governed by
§ 323, Defendant’s liability to the other members of her family is properly governed by § 324A.7
See Grogan, 535 S.W.3d at 872–73. Thus, the district court’s holding that § 324A was
inapplicable to Plaintiffs’ Tennessee tort law claim was erroneous.
Applying § 324A to the facts of this case, Defendant chose to send the December 12,
2015 email to Plaintiff Megan Fox, and in doing so plainly sought to warn her of the dangers
posed by the hoverboard. The body of the email stated: “There have been news reports of safety
issues involving products like the one you purchased that contain rechargeable lithium-ion
batteries. As a precaution, we want to share with you some additional information about lithium-
ion batteries and safety tips for using products that contain them.” (RE 117-17, PageID # 1402.)
And Defendant just as plainly recognized the warning as necessary for the protection of a third
party or his things. The body of the email also specifically requested that the recipient “pass
along this information” to the proper person if the hoverboard was purchased for someone else.
(Id.) Thus, we hold that Defendant assumed a duty to warn Plaintiff Megan Fox of the dangers
posed by the hoverboard when it sent her the December 12, 2015 email. See Grogan,
535 S.W.3d at 874 (“[T]he question of whether one has assumed a duty to act is . . . a question of
law.”) (alterations in original) (quotation omitted).
Given that Defendant assumed a duty to act, there remain genuine issues of material fact
regarding whether Defendant breached that duty and whether any breach caused Plaintiffs
physical harm. For instance, there is a genuine issue of material fact regarding whether
Defendant’s failure to include certain information in the December 12, 2015 email amounted to
7Plaintiff Megan Fox does not allege that she suffered any physical harm, therefore we need not decide
whether she forfeited her § 323 claim, for it fails as a matter of law. See Grogan, 535 S.W.3d at 874.

negligence. The email did not inform hoverboard purchasers of any of the actions Defendant had
taken to evaluate the dangers posed by hoverboard, including the findings and results of its
internal investigation. The email did not inform hoverboard purchasers that the reported safety
issues included a risk of fire or explosion. And the email did not inform hoverboard purchasers
that Defendant had ceased all hoverboard sales worldwide.
Additionally, there is a genuine issue of material fact regarding whether Plaintiff Megan
Fox read the December 12, 2015 email, and thereby could have acted in reliance on it.
Such reliance is required by subsection (c) of § 324A, one of three subsections under which
Plaintiffs’ claim may proceed. Though Plaintiff has no specific recollection of reading the email,
she “had a habit” of reading emails sent to her email address. (RE 161, PageID # 2210.)
Plaintiff also testified that she would not have let the hoverboard enter or remain in her home had
she known, among other things, that there had been 17 complaints of hoverboard fires or
explosions in the United States that involved hoverboards purchased on Defendant’s
marketplace, that Defendant anticipated additional complaints, particularly during the holiday
season in late December, or that Defendant had ceased all hoverboard sales worldwide.
Thus, we hold that there are genuine disputes of material fact regarding Plaintiffs’
Tennessee tort law claim, and reverse the district court’s dismissal.8
C. Plaintiffs’ Tennessee Consumer Protection Act (“TCPA”) Claim
The TCPA prohibits “[u]nfair or deceptive acts or practices affecting the conduct of any
trade or commence,” including “[c]ausing likelihood of confusion or of misunderstanding as to
the source, sponsorship, approval, or certification of goods or services.” Tenn. Code Ann. § 47-
18-104(a), (b)(2). In this case, Plaintiffs allege that Defendant’s policy allowing third-party
sellers to choose “friendly names” by which they would be identified as a seller of their products
caused a likelihood of confusion or misunderstanding as to the source of the hoverboard.
Specifically, Plaintiffs allege that Defendant’s policy deceptively caused Plaintiff Megan Fox to
8Defendant concedes that the Communications Decency Act, 47 U.S.C § 230, does not grant it immunity
from Plaintiffs’ Tennessee tort law claim. (RE 120, PageID # 1583.) (“All of Plaintiffs’ claims except those arising
from the December 12 email require treating Amazon as a publisher of W-Deals’ offer.”).

No. 18-5661 Fox, et al. v. Amazon.com, Inc. Page 17
believe that Defendant owned the hoverboard, and that she was purchasing the hoverboard from
Defendant.
The district court held that Plaintiffs did not “demonstrate a sufficient causal link” to state
their TCPA claim. (RE 161, PageID # 2227.) On appeal, Plaintiffs argue (1) that they did
demonstrate a sufficient causal link, and (2) that the district court erroneously granted summary
judgment on grounds not briefed by the parties. Defendant argues that the district court properly
determined that Plaintiffs did not demonstrate a sufficient causal link.
In order to prevail on a claim under the TCPA, “the alleged unfair or deceptive act or
practice must in fact cause the damages of which the plaintiff complains.” White v. Early,
211 S.W.3d 723, 743 (Tenn. Ct. App. 2006). Accordingly, Plaintiffs must demonstrate that
Plaintiff Megan Fox would not have purchased the hoverboard but for W2M’s choice and use of
the “friendly names” “W-Deals” and “-DEAL-.” Plaintiffs rely solely on Plaintiff Megan Fox’s
affidavit to satisfy this element of their TCPA claim.
Plaintiff’s affidavit states that she “do[es] not recall noticing the name ‘-DEAL-’ as the
seller of the hoverboard.” (RE 146-3, PageID # 1942.) While it also states that “even if [she]
had noticed the name ‘-DEAL-’ as the ‘[s]eller’” she would not have “recognized or understood
those names to refer to a third-party seller,” that statement does not demonstrate the requisite
causal link. It does not establish that but for W2M’s choice and use of the “friendly names” “W-
Deals” and “-DEAL-” Plaintiff would not have purchased the hoverboard. See Hamlin v. Trans-
Dapt of Cal., Inc., 584 F. Supp. 2d 1050, 1058 (M.D. Tenn. 2008) (granting judgment as a matter
of law on a TCPA claim because “there [was] no indication that [the plaintiff’s] loss was caused
by . . . reliance on a false impression” created by the defendant).
Plaintiffs also argue that the district court improperly granted summary judgment on
causation grounds because causation was not briefed by the parties. See Smith v. Perkins Bd. of
Educ., 708 F.3d 821, 828 (6th Cir. 2013). However, Defendant asserted in support of its motion
for summary judgment that Plaintiffs “d[id] not tie any Amazon conduct to any acts or practices
declared unlawful by Section 47-18-104(b) of the TCPA.” (RE 120, PageID # 1579.) This

-- 17 of 18 --

No. 18-5661 Fox, et al. v. Amazon.com, Inc. Page 18
assertion was sufficient to put Plaintiffs “on notice that [they] had to muster the necessary facts
to withstand summary judgment” on causation grounds. Smith, 708 F.3d at 829.
Thus, we hold that there is no genuine issue of material fact regarding Plaintiffs’ TCPA
claim, and affirm the district court’s dismissal.9
CONCLUSION
For the reasons set forth above, we AFFIRM the district court’s summary judgment
order with respect to Plaintiffs’ TPLA and TCPA claims, and REVERSE the district court’s
summary judgment order with respect to Plaintiffs’ Tennessee tort law claim.
9Accordingly, we need not decide whether the Communications Decency Act, 47 U.S.C. § 230, grants
Defendant immunity from Plaintiffs’ TCPA claim.
