In Romans v. Texas Instruments, Inc., No. CA2013-04-012 (Ohio Ct. App. Nov. 18, 2013), the Ohio Court of Appeals reviewed an order granting summary judgment to the defendant manufacturer of a component part of a Ford truck that caught fire, resulting in the death of plaintiff’s family.  The court held that under Ohio law, the component parts doctrine requires a plaintiff suing a component part manufacturer to establish either that (a) the component part itself was defective or (b) the component part manufacturer participated in the design integrating the component part into the completed product.  The court ruled that plaintiff had not shown that the component at issue was itself defective, nor had it shown that the defendant component part manufacturer had participated in designing how its switch was to be integrated into the truck.  As a consequence, the court affirmed the summary judgment for the defendant component parts manufacturer.
