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