Rule of Law:
Under Texas products liability law, a plaintiff's claim for design defect fails if the proposed safer alternative design is merely conceptual and is not supported by evidence that it would have significantly reduced the risk of injury without impairing the product's utility. Additionally, a manufacturer has no duty to warn sophisticated users, such as those in a specialized industry, of risks that are common knowledge within that industry.
Facts:
- Rodger Smith was a cable technician for Longview Cable Company.
- Longview Cable Company purchased an extension ladder with a U-shaped hook assembly from Louisville Ladder Corp. for its technicians.
- While on a job, Smith rested the ladder's hooks against a cable strand that was approximately 20 feet off the ground and had a natural downward slope.
- Smith climbed the ladder without first securing it to a stationary object, intending to secure it after he reached the top.
- At the top of the ladder, Smith's weight shifted, causing the ladder to slide sideways along the sloped cable.
- During the slide, one of the hooks disengaged from the cable, which caused the ladder to twist abruptly and come to a halt.
- The sudden twisting motion caused Smith to lose his grip, fall to the ground, and sustain serious injuries.
- Lateral slides of ladders along cables were a well-recognized risk in the telecommunications industry, and Smith himself had previously experienced several such slides without injury.
Procedural Posture:
- Rodger Nelson Smith sued Louisville Ladder Corp. in federal district court, asserting claims of defective design, failure to warn, and breach of implied warranty.
- The case was tried before a jury, which returned a verdict in favor of Smith on all three theories.
- The jury found Smith 15% contributorily negligent and awarded total damages of $1,487,500.
- The district court entered judgment on the jury's verdict.
- Louisville filed post-judgment motions seeking judgment as a matter of law, which the district court denied.
- Louisville, as the appellant, appealed the district court's judgment to the U.S. Court of Appeals for the Fifth Circuit. Smith is the appellee.

Issue:
Under Texas products liability law, does expert testimony proposing a conceptual alternative design that does not quantify the reduction in risk or evaluate the design's own hazards constitute legally sufficient evidence to prove a design defect and breach of implied warranty, and does a manufacturer have a duty to warn of risks commonly known within a specialized industry?
Opinions:
Majority - Judge W. Eugene Davis
No. The evidence presented was legally insufficient to support the jury's verdict on any of the plaintiff's theories. To prove a design defect, a plaintiff must establish that a proposed safer alternative would have significantly reduced the risk of injury without substantially impairing the product's utility, which Smith failed to do. Furthermore, a manufacturer has no duty to warn sophisticated users of dangers that are already common knowledge within their industry. Regarding the design defect claim, Smith's expert, Dr. Packman, proposed a conceptual latching device but admitted it was preliminary and that he had not conducted a risk-benefit analysis. Dr. Packman could not quantify the reduction in force his design would provide or state that it would have prevented Smith’s fall, only that it would diminish the possibility. This fails to meet the statutory requirement that an alternative design “significantly reduce the risk” of injury. Furthermore, the expert conceded his design might introduce new hazards, failing to prove it would not “substantially impair the product’s utility.” Because Texas law requires the same proof of a safer alternative design for a breach of implied warranty claim based on a defective design, that claim also fails. Regarding the failure-to-warn claim, there is no duty under Texas law to warn of risks that are common knowledge within the community of users. Louisville marketed the ladder to the telecommunications industry, a group of sophisticated users. Overwhelming evidence from industry safety manuals and training videos demonstrated that the hazard of lateral slides and the methods for preventing them were common knowledge in the industry, relieving Louisville of a duty to provide a more specific warning.
Dissenting - Judge Dennis
Yes. There was a legally sufficient evidentiary basis for a reasonable jury to find for the plaintiff, and the majority errs by improperly re-weighing the evidence and misapplying Texas law. The majority impermissibly considers a new ground for judgment as a matter of law that was not raised in the district court and incorrectly applies a sufficiency of evidence standard derived from Louisiana law rather than the established federal standard. Under Texas law, a plaintiff is not required to build a prototype or provide mathematical quantification of risk reduction to prove a safer alternative design; qualified expert testimony is sufficient. Dr. Packman’s tests and testimony provided ample evidence for the jury to conclude that a simple, feasible spring-latch design would have prevented the hook from disengaging, significantly reducing the violent torsional force that threw Smith from the ladder. The majority substitutes its own judgment for the jury's on the weight of the evidence and credibility of witnesses, which is improper under the federal standard for reviewing a jury verdict. The jury’s findings on all claims were supported by the evidence and should be affirmed.
Analysis:
This decision significantly clarifies the evidentiary requirements for plaintiffs asserting design defect claims under Texas's products liability statute. It establishes that merely proposing a conceptual alternative design is insufficient; a plaintiff must present concrete evidence that the alternative would both significantly reduce the risk of injury and not substantially impair the product's overall utility or introduce new hazards. The ruling also strongly reaffirms the sophisticated user doctrine in failure-to-warn cases, providing a robust defense for manufacturers whose products are sold to specialized industries with inherent, well-known risks. The dissent highlights a critical tension in diversity cases regarding the proper standard of appellate review and whether a federal court has overstepped its bounds by re-evaluating factual determinations made by a jury under state substantive law.
