2023 (Gyo-Ke) 10098 [Laundry Detergent Composition] <Shoji>
*The component is of low importance.
—No particular technical significance in the numerical range
⇒ A design matter!
“A component positioned as optional … was not highly important …; the examples did not achieve better deodorizing effects than other examples …”; no “particular technical significance”
(Excerpt from the court's reasoning)
…The specification indicates that component (G), meaning “a surfactant other than component (A),” is positioned as an optional component and was not highly important. Further, for G-2, G-2′, and G-3 included in component (G) specified in Invention 1, the examples using them did not achieve superior deodorizing effects compared with other examples in the deodorizing-effect evaluation. Thus, no particular technical significance is found in specifying component (G) as general formula (I) or (II) in Invention 1. At least, examining the nonionic surfactant (component (G)) content within the range in the invention in Exhibit Ko 1 and setting it at “20–25 mass%” is found to be a design matter for a person skilled in the art.
