I. BACKGROUND

Plaintiff brings this action for an allegedly defective rental wheelchair. Plaintiff is a
disabled individual who has been confined to a wheelchair since undergoing multiple hip and
spine surgeries. On January 19, 2016, Lincare, a company that “whether by rental or sale”12
“supplies durable medical equipment . . . [including] wheelchairs to patients from whom doctors
order their use for the patient’s needs,”13 delivered to Plaintiff’s home a non-motorized
wheelchair.14 Upon delivery, Plaintiff received an operating manual and signed a Manual
Wheelchair Orientation checklist.15 Plaintiff claims the Lincare delivery representative then
represented to Plaintiff that the wheelchair had a 300-pound weight capacity.16
In October 2016, Plaintiff claims he repositioned himself about once every hour to relieve
pressure on an ulcer sore,17 but that his “pressing down the armrests to pull himself up from the
wheelchair to adjust his position was never excessive.”18 On October 29, 2016, while

repositioning himself, Plaintiff “fell from [the subject] wheelchair and broke his femur after the
wheelchair’s [left] armrest broke.”19 Plaintiff claims he weighed 160 pounds at the time.20

12 Dkt. No. 33 p. 6.
13 Id. at p. 5.
14 Dkt. No. 22-1 p. 31. Before Lincare’s delivery of the wheelchair at issue, Plaintiff used a wheelchair borrowed
from his former rehabilitation facility. While the issues with the “first” wheelchair are noted in Plaintiff’s
deposition, the “first” wheelchair is not at issue in this case. Thus, any further reference to the wheelchair at issue is
in reference to what Plaintiff considers his “second” wheelchair. The Court notes Plaintiff also mentions other
wheelchairs either observed, gifted, or delivered, but such are not the basis of this case.

20 Dkt. No. 22-1 p. 21 (Martinez Dep. 79:14–15).
As a result of the fall, Plaintiff underwent reparative surgery on his femur on or about
November 1, 2016.21 Three days later, Plaintiff alleges Lincare “picked up the defective
wheelchair (Serial Number: 4515[1]0291[0]60 – Model Drive Cruiser X4) and delivered a new
wheelchair (Serial Number: 451608220926) for Plaintiff to use.”22 As addressed below, the
parties dispute any issues with the wheelchair’s armrest at or after delivery and whether Plaintiff

contacted Lincare about any issues with the wheelchair before the subject incident. The subject
wheelchair has apparently since been lost.23 However, Plaintiff and Plaintiff’s counsel’s brother,
Plaintiff’s original counsel,24 may still have possession of some parts.25
Plaintiff filed his original petition in state court on September 17, 2018,26 bringing claims
against Defendants for manufacturing and design defects; marketing defects; negligence; breach
of express and implied warranties of merchantability; and breach of implied warranty of fitness
for a particular purpose.27 Medical Depot, the alleged manufacturer but admitted seller28 of the
subject wheelchair to Lincare,29 received service of process on October 8, 2018;30 filed an
answer in state court on October 29, 2018;31 and removed to this Court on November 6, 2018, on

21 Dkt. No. 1-4 p. 7, ¶ 13.
22 Id. at pp. 7–8, ¶ 13. The Court notes Plaintiff’s signed Manual Wheelchair Orientation Checklist provided at
delivery lists the Manufacturer as “Drive,” Model CX418ADDASF, and Serial/LECS as #451510291060. Dkt. No.
31-3 p. 7. It is unclear if “Drive” is referring to Medical Depot or “Model Drive Cruiser X4.” However, Plaintiff
never raises this issue.

Defendants first learned Plaintiff still had parts from the wheelchair. Dkt. No. 22-1 pp. 14–15 (Martinez Dep. 50–

the basis of diversity jurisdiction.32 Lincare received service of process on October 9, 2018,33 and
filed an answer in this Court on November 8, 2018.34
On December 4, 2018, the Court issued a case-specific scheduling order in accordance
with Rule 26 guidelines and the parties’ requests in their joint discovery/case management
plan.35 The Court set a deadline for Plaintiff to designate expert witnesses and reports by June 1,

2019; Defendants to designate expert witnesses and reports by July 1, 2019; and the parties to
complete discovery by September 27, 2019.36
Despite the six-month period between the Court’s scheduling order and Plaintiff’s first
deadline, Plaintiff failed to meet its deadline to designate expert witnesses and reports.
Defendants met their deadlines to designate expert witnesses and reports.37 Two months after
failing to timely designate expert witnesses, Plaintiff filed a motion for leave to designate late
expert witnesses “who can testify and opine for the medical treatments that [Plaintiff] received as
a result of this accident.”38 The Court denied the motion, noting Plaintiff failed to identify an
expert on damages and liability, among other deficiencies.39
Thereafter, Medical Depot filed the instant motion for summary judgment.40 Medical

Depot maintains it purchased the wheelchair from an unnamed third-party manufacturer; contests
Plaintiff’s contention that Medical Depot designed and manufactured the wheelchair; and argues
it is an “innocent seller” under the Texas Products Liability Act.41 Plaintiff responded,42 and

Medical Depot replied and objected to Plaintiff’s summary judgment evidence.43 Lincare also
filed the instant motion for summary judgment, acknowledging that it delivered the wheelchair to
Plaintiff and arguing it is an “innocent seller” under the Texas Products Liability Act.44 Plaintiff
responded,45 Lincare replied,46 and Plaintiff filed a surreply.47 Lincare later filed the instant
unopposed motion to supplement its motion for summary judgment to include exhibits
referenced in an attached affidavit.48 The parties have filed their Court-ordered joint pretrial

order.49
Two days before the originally scheduled December 20, 2019 final pretrial conference,
Plaintiff requested a six-month continuance and extension of the September 27, 2019 discovery
deadline.50 The Court denied such request, pointing out Plaintiff’s counsel’s “apparent disregard
for his client’s and opposing counsel’s time and the Court’s judicial resources” and “multiple
opportunities . . . to remedy his manifest failure to timely recognize his case management
deficiencies.”51 The Court nonetheless continued the final pretrial conference to January 21,
2020, and ordered Plaintiff’s counsel to appear for a show cause hearing on January 21, 2020.52

The motions are now ripe for review. The Court begins with Lincare’s motion to
supplement then turns to Defendants’ motions for summary judgment.

II. MOTION TO SUPPLEMENT

Lincare requests to supplement its provided affidavit of Ricardo Benavides, Exhibit B
attached to its motion for summary judgment, because one of the exhibits referenced in the
affidavit was “erroneously not attached [] at the time of filing.”53 Lincare states, “[t]his filing
will complete the Exhibit B . . . [t]hese documents are known to the parties as they were the
subject of testimony and examination at Plaintiff’s deposition.”54 The Court notes the requested
supplemental exhibits are already provided in the record. Nevertheless, considering the parties’
lack of opposition, the Court GRANTS Lincare’s motion. The Court turns to the motions for
summary judgment.
III. MOTIONS FOR SUMMARY JUDGMENT

A. Legal Standard

The Court notes Medical Depot’s motion for “no evidence” summary judgment is only
available in Texas state court and not federal court.55 The Court thus applies the relevant federal
summary judgment standard. Under Federal Rule of Civil Procedure (“Rule”) 56, summary
judgment is proper when there is “no genuine dispute as to any material fact and the movant is
entitled to judgment as a matter of law.”56 “A fact is ‘material’ if its resolution could affect the
outcome of the action,”57 while a “genuine” dispute is present “only if a reasonable jury could
return a verdict for the non-movant.”58 As a result, “[o]nly disputes over facts that might affect
the outcome of the suit under the governing law will properly preclude the entry of summary

judgment.”59 “Although this is an exacting standard, summary judgment is appropriate where the
only issue before the court is a pure question of law.”60 As to the question of law, because federal
jurisdiction is invoked on the basis of diversity of citizenship,61 this Court, Erie-bound, must
adhere to grounds of relief authorized by the state law of Texas.62 Absent a decision by Texas’s
highest tribunal, the decisions by Texas courts of appeals control “unless [the Court] is
convinced by other persuasive data that the highest court of the state would decide otherwise.”63

The movant bears the initial burden of showing the absence of a genuine issue of material
fact,64 but is freed from this initial burden on matters for which the non-movant would bear the
burden of proof at trial; in that event, the movant’s burden is reduced to merely pointing to the
absence of evidence.65 If the movant meets its initial burden, the non-movant must then
demonstrate the existence of a genuine issue of material fact.66 This demonstration must
specifically indicate facts and their significance,67 and cannot consist solely of “[c]onclusional
allegations and denials, speculation, improbable inferences, unsubstantiated assertions, and
legalistic argumentation.”68

In conducting its analysis, the Court may consider evidence from the entire record,
viewing that evidence in the light most favorable to the non-movant.69 Rather than combing
through the record on its own, however, the Court looks to the motions for summary judgment

and responses to present the evidence for consideration.70 Parties may cite to any part of the
record, or bring evidence in the motions and responses.71 By either method, parties need not
proffer evidence in a form admissible at trial,72 but must proffer evidence substantively
admissible at trial.73
B. Analysis

As a threshold matter, the Court notes the parties generally characterize this case as a
“products liability” case. Despite Plaintiff including negligence and breach of warranties claims
in his complaint. In the parties’ proposed joint pretrial order, Lincare contests “[w]hether
Plaintiff can maintain an action for common law negligence and breach of warranty separate and
apart from a claim as defined under the [Texas Products Liability Act] against Lincare.”74
Plaintiff does not argue distinct theories of negligence or breach of warranties, but rather,
addresses his claim only as a products liability action. Accordingly, considering Plaintiff is the
master of his action, the Court finds Plaintiff’s claims for manufacturing and design defects;
marketing defects; negligence; and breach of warranties fundamentally arise out of personal

injuries caused by the alleged defective wheelchair and sound in products liability only, as
described below.
Importantly, the parties do not dispute Chapter 82 of the Texas Civil Practice and
Remedies Code (“Texas Products Liability Act” or “TPLA”) governs this action.75 Defendants

individually argue they are “innocent sellers” not liable under a theory of products liability
because none of the TPLA’s relevant exceptions apply.76 The parties also disagree over the
requirement of expert testimony in this case, considering Plaintiff failed to designate any experts.
Thus, the Court must resolve whether Plaintiff presents evidence sufficient to (1) establish
whether Defendants can be held liable under the TPLA; and (2) proceed with his products

liability claims without expert testimony.
a. Defendants’ Liability Under the TPLA

Texas defines a “products liability action” as:

[A]ny action against a manufacturer or seller for recovery of damages arising out
of personal injury, death, or property damage allegedly caused by a defective
product whether the action is based in strict tort liability, strict products liability,
negligence, misrepresentation, breach of express or implied warranty, or any other
theory or combination of theories.77

The TPLA defines a “seller” as “a person who is engaged in the business of distributing or
otherwise placing, for any commercial purpose, in the stream of commerce for use or
consumption a product or any component part thereof.”78 A “manufacturer” under the TPLA is
“a person who is a designer, formulator, constructor, rebuilder, fabricator, producer,
compounder, processor, or assembler of any product or any component part thereof and who
places the product or any component part thereof in the stream of commerce.”79 “[A]ll
manufacturers are also sellers, but not all sellers are manufacturers.”80

injuries or property damage caused by a defective product. See Hyundai Motor Co. v. Rodriguez ex rel. Rodriguez,
995 S.W.2d 661, 664 (Tex. 1999) (“Liability for personal injuries caused by a product’s defective design can be
imposed under several legal theories, among them negligence, breach of warranty, and strict products liability.”)).

(“With one exception, nothing in the statute precludes one person from being both with respect to the same product
“The common law has long taught that a manufacturer has no ‘duty to warn or instruct
about another manufacturer’s products, though those products might be used in connection with
the manufacturer’s own products.’”81 Traditionally, products liability law provides that “the
plaintiff must prove the defendant supplied the product that caused the injury. It is not enough
that the seller introduced products of similar design and manufacture into the stream of
commerce.”82 Under Texas law, an “innocent seller” is a nonmanufacturing seller of a product

who “is not liable for harm caused to the claimant by that product unless the claimant proves”
one of the following seven exceptions:
(1) that the seller participated in the design of the product;
(2) that the seller altered or modified the product and the claimant’s harm resulted
from that alteration or modification;
(3) that the seller installed the product, or had the product installed, on another
product and the claimant’s harm resulted from the product’s installation onto the
assembled product;
(4) that:
(A) the seller exercised substantial control over the content of a warning or
instruction that accompanied the product;
(B) the warning or instruction was inadequate; and
(C) the claimant’s harm resulted from the inadequacy of the warning or
instruction;
(5) that:
(A) the seller made an express factual representation about an aspect of the
product;
(B) the representation was incorrect;
(C) the claimant relied on the representation in obtaining or using the
product; and
(D) if the aspect of the product had been as represented, the claimant
would not have been harmed by the product or would not have suffered
the same degree of harm;
(6) that:
(A) the seller actually knew of a defect to the product at the time the seller
supplied the product; and

or its components. The exception is in section 82.002(d), which states: For purposes of this section, a wholesale
distributor or retail seller who completely or partially assembles a product in accordance with the manufacturer's
instructions shall be considered a seller.”).

82 Firestone Steel Prod. Co., 927 S.W.2d at 614 (citations omitted).
(B) the claimant’s harm resulted from the defect; or
(7) that the manufacturer of the product is:
(A) insolvent; or
(B) not subject to the jurisdiction of the court.83

Accordingly, if Plaintiff proves that any one of the seven exceptions individually applies
to Defendants, that Defendant may be held liable under the TPLA and cannot avail itself of the
“innocent seller” defense. The Court now discusses each Defendants’ liability.
i. Medical Depot’s Liability

Plaintiff alleges Medical Depot “manufactured, sold, distributed, and/or delivered . . .
designed, [], tested, warranted . . . and [] engaged in the business of designing, manufacturing,
testing, assembling, engineering, constructing, building, inspecting, marketing, advertising,
modifying, altering, rebuilding, selling, leasing, and/or distributing and placing into the stream of
commerce certain products, specifically [Plaintiff’s wheelchair] for sale to members of the
general public.”84 Plaintiff further alleges Medical Depot “knew the subject wheelchair had
various defects, specifically defective armrest, with respect to its safety, and was not suitable for
any use, thereby posing a serious threat of injury or death to its consumers, including Plaintiff.”85
Medical Depot argues it “sold the Wheelchair to Defendant Lincare, Inc. at some point but did
not manufacture the Wheelchair . . . there is no evidence that Medical Depot designed,
manufactured, altered or made an incorrect misrepresentation about the Wheelchair.”86 Medical
Depot further argues it “cannot be held liable under a theory of products liability because
Plaintiff has not presented any evidence that his claim falls under one of the seven exceptions

Inc., 2011 WL 2517141, at *2 (S.D. Tex. June 23, 2011)) (“Texas law ‘provides blanket protection for
nonmanufacturing sellers of products from liability for injuries caused by a defective product unless one of the
specified exceptions [under Section 82.003] appl[ies].”).

under Tex. Civ. Prac. & Rem Code § 82.003.”87 Medical Depot notes it “could not identify the
wheelchair in question because it was no longer available for inspection, but it would have been
manufactured by one of two manual assist wheelchair suppliers for [Medical Depot].”88
In support, Medical Depot provides (1) “Plaintiff’s Response to Defendant[s’] Request
for Disclosure;”89 and (2) Medical Depot’s own objections and answers to Plaintiff’s First Set of
Interrogatories.90 Plaintiff neither raises any argument in his reply and surreply nor attempts to

provide any evidence challenging Medical Depot’s arguments or evidence.91 “The party
opposing summary judgment is required to identify specific evidence in the record and to
articulate the precise manner in which that evidence supports his or her claim.”92 The Court has
no duty “to sift through the record in search of evidence to support a party’s opposition to
summary judgment.”93 Nevertheless, the Court notes Medical Depot’s own answers to Plaintiff’s
First Set of Interrogatories do not ordinarily constitute competent summary judgment evidence
because such are hearsay when offered by Medical Depot.94 However, Plaintiff has not objected.
Thus, the Court may consider Medical Depot’s proffered evidence.95

Medical Depot directs the Court to Plaintiff’s answers to Medical Depot’s Interrogatory
No. 16, Request for Production No. 19, and Request for Disclosure under Rule 194.2(c).96
Through Interrogatory No. 16, Medical Depot requests Plaintiff “state any and all facts which
support or relate to [Plaintiff’s] contention that ‘at the time, Defendants sold the subject
wheelchair to a Hidalgo County resident, Defendants knew the subject wheelchair had various

defects, specifically defective armrest, with respect to its safety, and was not suitable for any use,
thereby posing a serious threat of injury or death to its consumers, including Plaintiff.” Plaintiff
answers, “Plaintiff never thought he was going to fall. He trusted the company making them to
keep him safe, but in the end the company failed him because of how cheaply they were
made.”97 When asked by Medical Depot in its Request for Production No. 19 to “produce any
and all documents which support or relate” to the same abovementioned contention, Plaintiff
answers “None.”98 Finally, Plaintiff answers Medical Depot’s request for Plaintiff’s “legal
theories and, in general, the factual bases [for Plaintiff’s] claims or defenses” with “Plaintiff
believes that the wheelchairs are made cheaply and not put together well.”99 The record does not

reflect Plaintiff supplemented his answers. On this evidence, Plaintiff fails to show how Medical
Depot may be liable under a TPLA exception.
As exemplified above, Plaintiff recognizes his lack of evidence proving Medical Depot
meets any of the seven exceptions under Tex. Civ. Prac. & Rem Code § 82.003 to hold Medical
Depot liable for his harm caused by the alleged defective product in this case. Plaintiff makes no
effort to identify Medical Depot as “the company making [the subject wheelchair]” or present
related evidence sufficient to meet his burden on any of the available exceptions. Plaintiff fails to

articulate any attempt to obtain clarification of Medical Depot’s involvement with the subject
wheelchair or the identities of potential third-party suppliers as raised by Medical Depot. Absent
any evidence from Plaintiff that Medical Depot falls under any of the seven exceptions, the Court
finds Plaintiff fails to raise a genuine issue of material fact that could preclude summary
judgment in favor of Medical Depot on this ground.100 Thus, the Court GRANTS Medical

Depot’s motion. The Court turns to the issue of Lincare’s liability.
ii. Lincare’s Liability

Plaintiff makes the same allegations against Lincare as he does against Medical Depot.101
Both Plaintiff and Lincare agree that Lincare is a “seller” as defined by the TPLA,102 but Lincare
presents arguments as to why it does not fall under any of the seven exceptions under the
TPLA.103 Plaintiff’s response fails to directly address any of Lincare’s “innocent seller”
arguments or argue any particular exceptions apply. Rather, citing his own deposition, Plaintiff
primarily focuses on the expert testimony issue. Regardless, the Court briefly addresses each of
the TPLA’s exceptions and evaluates whether Plaintiff raises a genuine issue of material fact as
to any of the seven exceptions.
As to the first and second exception, Lincare argues it “did not manufacture or design the
wheelchair at issue or any of its accessory parts nor did it alter or modify the wheelchair or any

100 See SSP Partners, 275 S.W.3d at 458 (where the Texas Supreme Court held a plaintiff’s evidence sufficient to
raise an issue of fact precluding summary judgment for a defendant arguing there was no evidence the defendant
sold the actual lighter that caused the fire at issue where such evidence showed defendant imported the specific kind
of lighter used and plaintiff knew of no one else who imported the specific kind of lighter); Romo v. Ford Motor
Co., 798 F. Supp. 2d 798 (S.D. Tex. 2011) (where store that sold an allegedly defective tire could not be held liable
because plaintiff failed to present evidence showing the store had any connection to that tire).
101 Dkt. No. 1-4.
102 Lincare states “the wheelchair was rented by [Plaintiff’s] insurer for his use, and that renters of products are
treated as sellers for these purposes.” Dkt. No. 22 p. 8, ¶ C (citing Drake v. Penske Truck Leasing Co., LP, No. 4:12-

2015 WL 11573773, at *1 (W.D. Tex. July 29, 2015)).
103 Dkt. No. 22.
of its accessory parts.”104 Plaintiff fails to provide any argument or evidence to the contrary, and
in turn, fails to establish the application of these exceptions.
For the third exception, which concerns the product’s “installation” by Lincare and
Plaintiff’s resulting harm from such installation, Lincare argues “[t]he wheelchair required no
assembly and was not ‘installed’ as part of any other pieces of equipment.”105 In support, Lincare

points to the affidavit of Ricardo Benavides (“Mr. Benavides”), Lincare’s area manager for south
Texas branch offices, and Plaintiff’s own deposition.106 Mr. Benavides states:
Records kept by Lincare show that employee Eugene Velasquez delivered the
wheelchair. He delivered the wheelchair and completed the delivery paperwork
associated with the delivery on January 19, 2016 . . . Lincare did not add to,
modify, or remove any parts from the wheelchair before delivery to Plaintiff, and
it is the policy and procedure of the company that no such modifications of any
kind are made to equipment rented or sold to customers or patients . . .
Wheelchairs may be provided with accessory parts, for example – foot rests, that
come from a manufacturer, but those parts are not modified in any way by
Lincare personnel.107

Lincare points out that Plaintiff “testified the wheelchair was in a box and removed from its box
and packaging at delivery.”108 While Plaintiff does not offer a direct response to Lincare’s
argument, the Court looks to Plaintiff’s deposition testimony. When asked whether the
wheelchair was [allegedly] “flimsy from the time that . . . [the wheelchair] was originally
delivered” and whether Plaintiff had to assemble the wheelchair, Plaintiff simply responded the
wheelchair “was in a box . . . The person that came and dropped it off did it for me . . . .”109
Plaintiff makes no attempt to compare Lincare’s delivery of the wheelchair to an “installation” of

representative who dropped this off, did he remove all the packaging, the box that you said it was in? A: Yeah, he
took it out of the plastic and everything. . . . Q: Did – did you get in the wheelchair at the time of delivery? A: No,
because I was in my bedroom. And then he took it out of the box.”).
109 Dkt. No. 22-1 p. 4 (Martinez Dep. 9:6–13).
the wheelchair or an “installation” of the alleged defective part of the wheelchair, the armrest.
Plaintiff further fails to show a genuine issue of material fact as to Lincare installing the armrest
or the wheelchair because Plaintiff presents no evidence of Lincare installing the armrest onto
the wheelchair or substantively assembling the wheelchair. Even if such argument survived,
Plaintiff fails to show a genuine issue of material fact exists as to the “installation” causing

Plaintiff’s harm. Accordingly, no material factual dispute exists as to the application of the third
exception.
Lincare argues Plaintiff cannot establish causation under the fourth and fifth exceptions
where Plaintiff “cannot prove that any warning or representation caused his injury as he
admittedly failed to read any instructions or warnings regarding the wheelchair at issue and
admits that Lincare provided him no verbal instruction regarding the wheelchair at issue.”110
Through his response and deposition testimony, Plaintiff presents some argument for the Court’s
review. Because these exceptions are distinct, the Court discusses them separately.
For Plaintiff to survive summary judgment against Lincare under the fourth exception,

Plaintiff must prove that “[Lincare] exercised substantial control over the content of a warning or
instruction that accompanied the product; the warning or instruction was inadequate; and
[Plaintiff’s] harm resulted from the inadequacy of the warning or instruction.”111 In his affidavit,
Mr. Benavides states:
Lincare representatives do not provide advice or guidance from a biomechanical
viewpoint on a customer/patient’s safest or best method for wheelchair transfer
considering their medical or physical limitations and that such instructions would
be provided by a customer’s doctor, health care provider or person providing the
order for the equipment. Rather, any instructions provided or discussed with
customers regard only the equipment and are in conformity with information
provided by the manufacturer of the equipment at issue.112

110 Dkt. No. 22 p. 10, ¶ 3.
111 Tex. Civ. Prac. & Rem. Code Ann. § 82.003(a)(4) (West).
112 Dkt. No. 22-2 p. 3, ¶ 17.
Plaintiff has not directed the Court to any evidence to the contrary. Accordingly, there is no
genuine issue of material fact that Lincare does not exercise substantial control over the content
of accompanying wheelchair instructions provided to Plaintiff.
Even if Lincare exercised substantial control over such content, Plaintiff fails to prove
how “the warning or instruction was inadequate.” On the date of delivery, Plaintiff signed
Lincare’s “Manual Wheelchair Orientation Checklist,” affirming in relevant part: (1) under the
“General” section, Plaintiff “ha[d] the current manufacturer’s operating manual for the Drive
wheelchair and is advised to read it thoroughly;”113 under the “Safety” section, Lincare
“[e]xplain[ed] all warnings in the manufacturer’s operation instructions;” under the “Operating

the Wheelchair” section, Lincare “[e]xplain[ed] the parts of the wheelchair and the function of
each;” and under the “Routine Maintenance by Customer” section, Lincare “[i]nstruct[ed]
[Plaintiff] to periodically check the wheelchair for loose parts. Advise local center if problem
arises.”114 Yet, Plaintiff argues “the wheelchair lacked adequate instructions or warnings in
regard to the safety of the armrests, and the omission of the instructions or warnings rendered the
wheelchair not reasonably safe;”115 Plaintiff “did not receive any instructions or warnings from
[Lincare] in terms of pressing down the armrests to pull himself up to reposition or stand up;”116
and Lincare “never instructed or warned in regard to Plaintiff’s usage of the armrests to
reposition his body.”117 Confusingly, Lincare characterizes Plaintiff as a “‘sophisticated’ user of
wheelchairs at the time of Lincare’s delivery [who] did not need [the Lincare delivery

representative] to instruct [Plaintiff] on anything”118 and Plaintiff’s deposition testimony as
“admit[ting] that Lincare provided [Plaintiff] no verbal instruction regarding the wheelchair at
issue.”119 Nevertheless, Plaintiff does not provide evidence that would suggest or create a
genuine issue of material fact as to Lincare’s instructions, written or oral, being inadequate,
especially where Plaintiff instead presents evidence he ignored any provided instructions:

Q: Did – so when the [] wheelchair came . . . you’re saying [Lincare] didn’t give
you any paperwork to keep, and you didn’t have any questions for how this
wheelchair may operate differently than the first one. Is that right?
A: [Lincare] probably did, but you know, they don’t – I don’t – I don’t sit there,
bother reading agreements. Got in the wheelchair and just sit there or wheel
yourself around, whatever you’re going to do in the house.
Q: You don’t know if you got some paperwork from –
A: . . . [Lincare] probably gave it to me, but since I already had [the wheelchair],
why – as far as reading the manual on it.
Q: If you – if you got paperwork, did you – did you just set it aside and not look
at it?
A: Or my – my wife did.
Q: Okay. So if you got any paperwork, is it fair to say that you didn’t look at it
because you thought you already knew what you needed to know about operating
a wheelchair?
A: Yes.120

Plaintiff further fails to offer any evidence that his harm resulted from the inadequacy of
the instruction. Plaintiff has made clear his deliberate disregard for any provided instructive
materials and his self-proclaimed experience with wheelchairs. Yet, Plaintiff argues “[i]f
Plaintiff was given a proper instruction or warning in regard to pressing down the armrests of the
wheelchair to reposition his body, this falling accident would not have occurred.”121 Plaintiff
provides no evidence that a failure to instruct or an inadequate instruction on armrest use caused
his harm here. Accordingly, the fourth exception does not apply.

120 Dkt. No. 22-1 p. 21 (Martinez Dep. 77:9–18; 78: 6–17).
121 Dkt. No. 24 pp. 30–31, ¶ 9.
For the fifth exception, which concerns an express factual representation about an aspect
of the product, the Court first looks to the nature of Plaintiff’s relationship with Lincare. As
noted above by Mr. Benavides, Lincare becomes involved with customers like Plaintiff after “the
customer’s doctor, health care provider or person providing the order for the equipment”122
contacts Lincare. Plaintiff confirms communicating at some point with his insurance company
who set up the wheelchair order.123 Thus, by some combination of doctor recommendation and

insurance approval, Plaintiff received the subject wheelchair. Plaintiff does not present evidence
that this process requires Plaintiff to rely on any representation made by Lincare regarding an
aspect of the subject wheelchair. Plaintiff also presents no evidence that Lincare’s delivery
included any express factual representations regarding an aspect of the wheelchair enough for
Plaintiff to have relied on the representation.
Nevertheless, Plaintiff claims “the employee of Lincare represented to Plaintiff that the
wheelchair could handle a person whose weight is 300 pounds.”124 Plaintiff argues he “had no
reason to think that the armrest will break when he pushes the armrest to pull up his body to
reposition himself.”125 Still, Plaintiff’s alleged weight of 160 pounds and testimony of how the

armrest “broke off” does not create a genuine issue of material fact regarding whether the 300-
pound weight capacity representation was incorrect or whether such representation extended to
the weight capacity of the armrest, an aspect of the wheelchair.
The Court also agrees with Lincare that Plaintiff fails to prove the causation requirement
for the fifth TPLA exception, that “if the aspect of the product had been as represented,
[Plaintiff] would not have been harmed by the product or would not have suffered the same

degree of harm.” Plaintiff only presents unfounded causation theories that “improper
construction or defective materials caused this falling accident;”126 “the armrest broke not due to
heavy usage, but due to manufacturing, designing, and marketing defect, because it suddenly
broke off;”127 and “[a]lternative materials such as metals, stronger plastics, or carbon pieces to
the armrests on the wheelchair in question could have prevented it from breaking off which
ultimately caused Plaintiff to fall and break his femur.”128 None of this relates to Lincare’s

representation. Even where Plaintiff speculates the wheelchair “couldn’t handle my weight, or I
don’t know,”129 Plaintiff concedes “the people who study that and manufacture those are in a
better position to understand that.”130 Plaintiff’s speculation is not proof of how a wheelchair or
armrest with a 300-pound weight capacity would have prevented Plaintiff’s harm. The Court
finds the fifth exception does not apply.
As to the sixth exception, requiring proof that Lincare actually knew of a defect to the
product at the time the seller supplied the product and Plaintiff’s harm resulted from the defect,
Lincare’s evidence shows it “has no record of prior complaints or problems with [the subject]
wheelchair, identified on delivery and pick-up paperwork as Serial Number 4S1510291060.”131

Lincare also argues Plaintiff “cannot show that Lincare actually knew of any defect in the
wheelchair.”132 Lincare’s evidence further shows that, “when asked about what issue the

indicate that there were no complaints or requests for a change of wheelchair by Plaintiff or anyone acting on his
behalf before it was picked up [] on November 4, 2016, from the time of its delivery on January 19, 2016. If there
had been prior complaints or a separate request for a different wheelchair, it would have been noted in [Plaintiff’s]
file records. Lincare has no record of prior complaints or problems with this wheelchair, identified on delivery and
pick-up paperwork as Serial number 4S1510291060.”)
132 Dkt. No. 22 p. 13, ¶ 4.
wheelchair displayed, [Plaintiff] said it was ‘flimsy’ but not at the time of delivery.”133 Lincare
points out the wheelchair “remained in [Plaintiff’s] sole possession until the accident occurred,
having been removed in front of [Plaintiff] from its packaging.”134
Plaintiff provides no evidence Lincare actually knew of the alleged defect at the time of
delivery. Plaintiff alleges that “[p]rior to his fall from the wheelchair on October 29, 2016,”135 he

called Lincare about the defect, but was “[n]ot even sure of the date” and that no one got back
with him.136 Clearly, the only allegation of Plaintiff’s communication to Lincare about the
alleged defect does not take place at the time of delivery and does not even prove Lincare knew
of the defect. Accordingly, the sixth exception does not apply.
Finally, the seventh exception provides for liability against an “innocent seller” where a
manufacturer is insolvent or not subject to the Court’s jurisdiction, Lincare states, “[n]o such
information has ever been pled, much less is available.”137 As noted above, it is undisputed that
Plaintiff has not identified the appropriate manufacturer sufficient to establish liability. It is
further undisputed Lincare is not the manufacturer of the subject wheelchair. In turn, Plaintiff has

failed to establish any insolvency or jurisdictional status of the relevant wheelchair manufacturer.
The seventh exception thus does not apply here.
Therefore, the Court finds Lincare is a nonmanufacturing seller for the purposes of TPLA
and there is no genuine issue of material fact as to the application of any of the abovementioned
exceptions. The Court GRANTS Lincare’s motion for summary judgment on this ground.
b. Plaintiff’s Lack of Expert Testimony

The above analysis renders summary judgment proper. Yet, alternatively, the Court
briefly addresses the lack of expert testimony in light of the parties collectively providing more
briefing on the issue. “[P]roduct liability cases are quintessentially expert cases.”138 As noted
above, Plaintiff failed to designate an expert in this case. Without question, Plaintiff’s products
liability claims require proof of causation.139

“Whether expert testimony is necessary to prove a matter or theory is a question of
law.”140 “Under Texas law, ‘expert testimony is generally encouraged if not required to establish
a products liability claim.’”141 The Supreme Court of Texas has “consistently required expert
testimony and objective proof to support a jury finding that a product defect caused the
plaintiff’s condition.”142 Specifically, “[e]xpert testimony is required when an issue involves
matters beyond jurors’ common understanding.”143 “Proof other than expert testimony will
support a jury finding only when the jurors’ common understanding and experience will allow

139 The elements of Plaintiff’s claims are as follows. “Under Texas law, in order to recover for an injury on the
theory of products liability, the plaintiff bears the burden of proving that (1) the defendant placed a product into the
stream of commerce; (2) the product was in a defective or unreasonably dangerous condition; and (3) there was a
causal connection between that condition and the plaintiff’s injuries or damages.” Smith v. Robin Am., Inc., 484 F.
App’x 908, 912 (5th Cir. 2012) (citation omitted). Plaintiff’s manufacturing defect requires Plaintiff prove “the
product was defective when it left the hands of the manufacturer and that the defect was a producing cause of the
plaintiff's injuries.” Gharda USA, Inc. v. Control Sols., Inc., 464 S.W.3d 338, 352 (Tex. 2015) (quoting Ford Motor

must identify a specific defect by competent evidence and rule out other possible causes of the damage.” Id. (citing
Nissan Motor Co. v. Armstrong, 145 S.W.3d 131, 137 (Tex. 2004)). A Texas design defect claim requires Plaintiff
to prove “(1) the product was defectively designed so as to render it unreasonably dangerous; (2) a safer alternative
design existed; and (3) the defect was a producing cause of the injury for which the plaintiff seeks recovery.” Emery,
No. 19-20389, 2019 WL 6705285, at *2 (quoting Goodner v. Hyundai Motor Co., 650 F.3d 1034, 1040 (5th Cir.

but-for cause, namely one without which the event would not have occurred.” Id. (citing Ford Motor Co. v.
Ledesma, 242 S.W.3d 32, 46 (Tex. 2007)). “A marketing defect is proven when the evidence shows that a defendant

instructions renders an otherwise adequate product unreasonably dangerous.” Smith, 484 F. App’x at 912.

them to make that finding with reasonable probability.”144 “[When] the causal link is beyond the
jury’s common understanding, expert testimony is necessary.”145 “Lay testimony may be used as
evidence of causation in certain circumstances, but “[w]hen expert testimony is required, lay
evidence supporting liability is legally insufficient.”146 “[F]or expert testimony not to be required
in a products liability case, ‘the product itself, or at least the . . . feature in question, must be

relatively uncomplicated, and the implications . . . such that a layman could readily grasp
them.’”147
Defendants separately argue, “[e]xpert testimony is required where the causal connection
between an alleged defect and the claimant’s injuries is beyond the jury’s common
understanding . . . the connection between the alleged defect and [Plaintiff’s] injuries is beyond
the jury’s common understanding.”148 Medical Depot argues, “there has been no showing, and
there will be no showing, that Plaintiff can offer these opinions under Fed. R. Evid. 701 or 702.
There are a number of explanations for the wheelchair arm breaking as alleged by Plaintiff,
including but not limited to, the Plaintiff doing something to cause it to break. Expert testimony

is clearly required to prove a products liability claim, particularly one that involves a durable
medical product.”149 Lincare continues, “[Plaintiff] cannot proffer lay witness testimony in place
of expert testimony for evidence . . . Without expert testimony, [Plaintiff] cannot show evidence
of the wheelchair’s alleged defect, an element essential to his claims, and with no evidence of a

defect, [Plaintiff] cannot establish a causal connection between the defect and his alleged
damages.”150
Plaintiff first attempts to differentiate his case from those cited by Defendants151 because
“the cases that [Defendants] cites primarily are cases involving a manufacturing defect, rather
than a design defect,”152 thereby failing to realize Plaintiff pleads a manufacturing defect in this

case. Without citing to any supporting cases, Plaintiff further argues his “testimony supports his
position that an expert testimony is not necessary in this particular case because the defect and
the causation in the present case do not involve the complexity that requires expert testimony to
help [the] jury to understand the issues. Even without [] expert testimony, Plaintiff can prove his
case . . . [t]he testimony of Plaintiff and Plaintiff’s treating physicians are sufficient to raise a fact
issue which should be presented to a jury.”153 Plaintiff then presents to the Court the following
causation theories: (1) “if Defendant added [a] seatbelt to the wheelchair or used other alternative
materials for the armrest, this falling accident could have been prevented;”154 (2) “the armrest
broke not due to heavy usage, but due to manufacturing, designing, and marketing defect,
because it suddenly broke off;”155 (3) “[Plaintiff] believes that the cause of the falling incident

was that the armrest of the wheelchair could not handle his weight;”156 (4) “[p]ressing down the
armrests to pull himself up from the wheelchair to adjust his position . . . was not the cause or
contributing factor in the falling incident;”157 and (5) “[a]lternative bolt and nut mechanism

could have prevented the falling accident.”158 The Court finds expert testimony is required in this
case.
The Court is unaware of a products liability case involving an allegedly defective
wheelchair able to proceed without expert testimony as to the alleged defect. Rather, courts in
this Circuit have evaluated the need and relevancy of wheelchair experts in similar circumstances

with heightened scrutiny. In Dorsey v. Relf, the plaintiff, a wheelchair user for 35 years, failed to
designate an expert who could provide testimony “concerning the degree of care which a
physical therapist of ordinary prudence and skill would have exercised in the same or similar
circumstances, whether [plaintiff’s physical therapist] breached that standard of care, and
whether any such breach was a proximate cause of plaintiff’s injury.”159 The Dorsey court
opined “the need to provide instructions and warnings to a wheelchair user” is not a matter of
common knowledge, as a “wheelchair is a medical device.”160
In McSwain v. Sunrise Med., Inc., where wheelchair anti-tip tubes were at issue, the
Court held the designated expert, a mechanical engineer, was qualified to “test the angle at which

the wheelchair can be tipped back before tipping over, and to explain how different factors, such
as the thickness of the seat cushion, the wheelbase measurement of the front and back tires, and
whether the tires are hard or soft plastics, affects the center of gravity, the stability of the chair,
and the propensity to tip.”161 However, the Court reserved the right to limit the expert’s
testimony at trial to matters that met his qualifications “as a mechanical engineer and [were]
outside the scope of the average juror’s experience and knowledge” because the expert’s “lack of
experience and knowledge of wheelchair use [was] troubling . . . [the expert] conclude[d] that

anti-tip tubes should be standard, but [had] no knowledge of the benefits of wheelchairs without
anti-tip tubes and [the expert] relie[d] on his own hypothesis, without the benefit of any
experience or education in wheelchair use or training, that the vast majority of wheelchair users
cannot do a wheelie at will.”162
Further, in Gibson v. Invacare Corp., an expert with qualifying engineering credentials

who examined the alleged defective hemi-walker compared it with identical models and
produced detailed findings was qualified to testify.163 Even when the alleged defective
wheelchair is unavailable for an expert’s examination, an expert with qualifying engineering
credentials may provide testimony where “calculations are based on a reliable formula and [the
expert’s] assumptions are based on direct evidence in the record.”164 Finally, the Fifth Circuit has
held, in the context of a products liability case involving a child’s car seat, expert testimony as to
armrest detachment is relevant and requires a reliable foundation.165
Based on the aforementioned, the Court finds the alleged defect and the causal link to
Plaintiff’s injuries is beyond jurors’ common understanding. Plaintiff fails to cite to any relevant

cases supporting his argument that his own testimony would suffice to establish causation.
Plaintiff’s own unfounded theories or reliance on alleged broken parts in his possession or
indistinct photographs will not suffice. Plaintiff further fails to present evidence that could serve

(“Rather, Dr. Clarke closely examined Gibson’s failed hemi-walker and two otherwise identical Model 6252 hemi-
walkers, and his report contains detailed findings. Perhaps Invacare’s arguments will sully Dr. Clarke’s veracity with
the jury at trial, but they are not enough to establish, for Rule 702 purposes, that his conclusions rest on mere
speculation.”).

to supplement his lack of expert testimony,166 even where the wheelchair is unavailable for
review.
Notably, the alleged defect and the causal link to Plaintiff’s injuries appears to be beyond
Plaintiff’s common understanding. Plaintiff provides no evidence a layman could readily grasp
the alleged defective feature in question and no indication he personally grasps the actual product

and alleged defect.167 First, it is unclear how often or thoroughly Plaintiff evaluated the
wheelchair:
Q: [W]hen the wheelchair gets dropped off to – to you – you understand that no
one from Lincare is watching how you’re using it or knowing how you’re using it
every day right?
A: Right.
Q: And you understood that once it was in your possession you had to continue to
monitor its condition, correct?
A: Of course.
Q: So that means you’re going to visually look at the wheelchair, right?
A: I just sit on it. I mean, there’s no way to physically look at it.168

Although Plaintiff speculates one of the parts gathered by his wife after the fall was “supposedly
used to adjust height of armrests,”169 he acknowledges this part had nothing to do with his
accident.170 Plaintiff’s deposition testimony also reveals that Plaintiff did not read the
wheelchair’s instructions and Plaintiff inconsistently describes the armrest and wheelchair as
“broken,” “loose,” or “flimsy.”171 Accordingly, Plaintiff has not shown an understanding of the

166 See Kleppel v. Hunter’s Mfg. Co., Inc., No. 4:16-CV-03715, 2018 WL 6436269, at *9–10 (S.D. Tex. Dec. 7,
2018), reconsideration denied, No. 4:16-CV-03715, 2019 WL 1438324 (S.D. Tex. Apr. 1, 2019) (“While it is true
that Kleppel has not presented a study, data, or expert testimony to show that a [patented] Guard [to a particular
crossbow] would have prevented or significantly reduced the risk of her injury, Kleppel has produced evidence that
the Guard is designed precisely to prevent or significantly reduce the risk of her type of injury . . . Despite Kleppel’s
failure to produce expert testimony, the Court finds that the evidence discussed above is sufficient to create a triable
question of fact regarding whether a safer alternative design for the TL-4 [crossbow] existed in 2006.”).

171 Dkt. No. 33; Dkt. No. 22-1 p. 14 (Martinez Dep. 50:11–21) (where Plaintiff states, “I didn’t even know it was
broken, to tell you the truth,” and when looking at the part he brought to the deposition, stating “I knew it was kind
of loose.”); Dkt. No. 22-1 p. 29 (Martinez Dep. 112:14–25) (where Plaintiff states the armrest “wasn’t loose or
cause, much less that the causal link is within his or the jury’s common understanding. Thus,
Plaintiff provides no evidence he would be qualified to testify as to the defect.
“Texas courts have repeatedly held that the mere fact that an accident occurred is not
sufficient proof [of a defect].”172 Plaintiff’s conclusory representations, speculations, and
emotions, namely that the wheelchair was “flimsy,” and Plaintiff felt “insecure” in the

wheelchair, do not constitute any evidence. Even if the Court permitted the testimony of
Plaintiff’s physicians, Plaintiff presents no information as to what Plaintiff’s physicians would
testify. Plaintiff offers nothing to show that his physicians can testify as to liability.
Accordingly, Plaintiff’s failure to provide any expert testimony also warrants summary
judgment. The Court alternatively GRANTS Defendants’ motions for summary judgment on this
basis. As no other claims or issues remain, the Court need not address the other pending motions.
IV. CONCLUSION
For the foregoing reasons, the Court GRANTS Lincare’s “Unopposed Motion to
Supplement Summary Judgment Evidence.”173 The Court also GRANTS Medical Depot’s “No
Evidence Motion for Summary Judgment”174 and Lincare’s “Motion for Summary Judgment,”175

thereby DISMISSING WITH PREJUDICE Plaintiff’s claims against Defendants. The Court
thus DENIES AS MOOT Lincare’s “Motion in Limine to Exclude Any References to Alleged

explains on an unknown date he told an unnamed girl the “wheelchair doesn’t feel right to me,” the girl allegedly
said “Well, I’ll have Mr. Rodriguez call you back,” and [Lincare employee] did not get back with Plaintiff).
