Lin v. Solta Medical, Inc.

Background

Hsin Lin alleged that she suffered second-degree burns during a laser skin treatment in Taiwan using a Thermage CPT device. She asserted claims for strict-liability design defect, strict-liability manufacturing defect, strict-liability failure to warn, negligent design, negligent manufacturing, negligent failure to warn, breach of express warranty, and breach of implied warranty. The opinion states that Lin confirmed the negligence claim concerned the alleged design, manufacturing, and warning defects rather than a separate general-negligence claim.

Solta moved for summary judgment, arguing in part that Lin could not show that the device was authentic, that the warning claims failed, that the design and manufacturing claims failed, that the warranty claims failed, and that punitive damages were unsupported.

Authenticity of the Device

The court denied summary judgment on Solta’s argument that Lin had not shown a genuine factual dispute about whether an authentic Thermage CPT device was used. Although the device was not produced and its serial number was not recorded in the medical records, Dr. Huang testified that he used a genuine Thermage CPT device and identified features matching the product manual. Medical records also stated that a Thermage device was used. The court held that this evidence created a factual issue for trial. Lin still must prove at trial that Solta manufactured the device, and Solta may present evidence to the contrary.

Failure-to-Warn Claims

The court granted summary judgment on both Lin’s strict-liability and negligent failure-to-warn claims. The court applied the parties’ agreed approach that the medical professional who used the device served as the relevant person to warn. The court found that Dr. Huang knew the Thermage CPT could cause burns and blisters, knew that the risk could increase when general anesthesia raised the patient’s pain tolerance, and had warned Lin about those risks.

The court also rejected Lin’s argument that Solta needed to warn specifically that using the Thermage CPT after an Ulthera treatment could increase the risk. The court held that the warnings about excessive heat did not need to identify every possible factor that could increase skin temperature. Because Dr. Huang already understood the risks, the court found no factual dispute about whether a different warning would have changed his conduct and caused a different outcome.

Design-Defect Claims

The court denied summary judgment on both the strict-liability and negligent-design claims.

For strict liability, the court held that Lin could proceed under California’s risk-benefit test but not under the consumer-expectations test. The court reasoned that the prescription-only Thermage CPT device was used by specialized physicians and trained medical professionals, so ordinary consumers could not be expected to have commonly understood safety expectations about the device.

Under the risk-benefit test, Lin identified the alleged design defect as the device’s reliance on the patient’s subjective pain reports instead of an objective measurement of subsurface skin temperature. She proposed a design that would measure subsurface temperature and automatically limit energy levels. The court found that Lin made the required initial showing that the alleged design defect could have caused her injury. Solta showed that burns occurred in 0.007% of treatments, but the court held that this evidence did not resolve factual questions about the feasibility, cost, and consequences of a safer alternative design. A jury therefore must weigh the competing risks and benefits.

The court also denied summary judgment on negligent design. It found a factual dispute concerning whether Solta took reasonable precautions in designing the device, including Lin’s evidence concerning sedation, the risk of burns, and possible safety features.

Manufacturing-Defect and Warranty Claims

Lin did not oppose Solta’s motion on the manufacturing-defect claims or the express- and implied-warranty claims. The court therefore granted summary judgment to Solta on those causes of action.

Punitive Damages

The court denied Solta’s request to prevent Lin from seeking punitive damages at trial. It found disputed factual questions about whether Lin was eligible for that remedy and concluded that those questions were more appropriately decided by a jury after hearing the parties’ trial evidence.

Disposition

The court granted in part and denied in part Solta’s motion for summary judgment. It denied the motion concerning the authenticity of the device; granted it on the strict-liability and negligent failure-to-warn claims; denied it on the strict-liability and negligent design-defect claims; granted it on the strict-liability and negligent manufacturing-defect claims and both warranty claims; and denied it on punitive damages.
