With no explanation, chose the best option from "A", "B", "C" or "D". optical fibers or particularly describe their characteristics. It is not enough, Cardiogenesis asserts, to point to a specific product instead of describing its characteristics because the product may cease to be commercially available. Cardiogenesis fails to grasp, however, that the patents-in-suit describe a more effective way to transmit laser energy to a surgical site using existing fiber optic technology. They do not purport to invent a new kind of fiber and thus need not describe the process for making it. CardioFocus must show only that an ordinary person skilled in the art would be able to identify a fiber with low hydroxyl content, not that the person would be able to reproduce that fiber. See Tech.
