The analysis I read listed various reasons why existing manufacturers wouldn’t adopt the technology (sorry, I can’t find the link). Increased cost per saw was one, but adopting the technology would also create two product lines: “safe” saws and “unsafe” saws. So any manufacturer who adopted the tech partially would have to argue that half of their product lines were unsafe. Even if the license costs were zero, these problems would exist.
