*Although not stated in the specification, it was possible to recognize that one of two measurement methods should be used.
⇒ Numerical limitation satisfied!!
“A person skilled in the art recognizes that the SCI method is … strongly affected by the gloss of the packaging … and is therefore … inappropriate … and could recognize that the SCE method should be used.”
(Excerpt from the court's reasoning)
The difference between measurements obtained by the SCE and SCI methods arises from whether specular reflection is included in the measured value. It is generally known that highly glossy substances produce stronger specular reflection…. Since visual inspection of meat and similar products covered with packaging often shows that the packaging is glossy, a person skilled in the art would recognize that the SCI method is inappropriate: it would be strongly affected by the gloss of the packaging and would yield absorbance different from that corresponding to the proportion of myoglobin in the measured object. …Taking into account the significance of the invention and this common general technical knowledge, a person skilled in the art could recognize that the SCE method should be used when measuring absorbance through packaging as the basis for calculating the proportion of myoglobin in roast beef in the invention.
