Case Brief Summary & Legal Analysis
tl;dr: A manufacturer was held liable for a table saw injury. The court affirmed that failing to incorporate an available, albeit costly, flesh-sensing safety technology could constitute a design defect, rejecting the argument that this imposed impermissible “categorical liability” on low-cost saws.
Legal Significance: Reinforces that under a risk-utility test, a jury can find a design defective for omitting a safety feature even if it significantly increases cost and alters product characteristics. The case clarifies the distinction between a standard design defect claim and a disfavored “categorical liability” claim.

Case Facts & Court Holding
Key Facts & Case Background
Plaintiff Carlos Osorio suffered a severe hand injury while operating a Ryobi Model BTS15 benchtop table saw. He sued Ryobi, the manufacturer, for breach of the implied warranty of merchantability, alleging a design defect. Osorio’s claim centered on the saw’s lack of “SawStop” technology, a flesh-detection safety system that immediately stops and retracts the blade upon contact with skin. Plaintiff’s expert, the inventor of SawStop, testified that the technology was available and had been presented to Ryobi years before the accident. Ryobi countered that incorporating SawStop was not a feasible alternative for its low-cost ($179), portable saw. It argued the technology would add substantial cost (estimated at under $150), weight, and size, fundamentally altering the product’s defining characteristics and placing it in a different market category. The jury found for Osorio, awarding him $1.5 million. The district court denied Ryobi’s subsequent motion for judgment as a matter of law, and Ryobi appealed.
