In State Farm Fire & Cas. Co. v. Coway USA, Inc., No. 22-cv-3516, 2024 U.S. Dist. LEXIS 192849, the United States District Court for the Eastern District of Pennsylvania (District Court) considered whether the plaintiff produced sufficient evidence to establish that the defendant sold and/or marketed a product and, thus, could be held liable for an alleged defect in the product. The plaintiff, a subrogating insurance carrier, brought strict product liability and breach of warranty claims against the defendant—the installer of a bidet in its insured’s home—claiming that the defendant also marketed and sold the bidet. The sole evidence to support a finding that the defendant sold the bidet was the homeowner’s testimony that she bought the product from the installer. The court found that the insured’s testimony, without any documentation or other corroborating evidence, was insufficient to establish that the defendant sold the product. Since proof of a sale is a required element for strict product liability and breach of warranty claims, the District Court granted the defendant’s motion for summary judgment, dismissing the case.

This case involved a water loss to the Pennsylvania residence of Mikyung Kim and her husband Adrian Kim (collectively, the Kims) that was discovered in April 2021. An investigation revealed that the water loss originated from the failure of a bidet for a toilet in the second-floor bathroom. The Kims alleged that defendant, Coway USA, Inc. (Coway), sold the bidet and installed it around 2010. An employee of the plaintiff’s liability expert, a materials engineer, opined that a T-connector—a plastic valve that regulates the flow of water to and through the bidet—failed due to overtightening of the connector during the manufacturing process.
