Case No. 2025 (Gyo-ke) 10027
[Hinge] (Presiding Judge Hasegawa)
*Inventive step recognized
A configuration for solving the problem of the primary cited invention cannot be changed without a particular reason. (What constitutes a particular reason?)
(Excerpts from the judgment — translated)
Given that the configuration of the invention in Exhibit Ko 3, namely the arrangement of arm support projections 16 and 17 outside the first cam portion 22 and second cam portion 23, is a configuration for solving the problem, it cannot be said that a person skilled in the art could readily have conceived of changing it without a particular reason to a configuration in which a pair of support portions of the first wing member of Invention 1 at issue supports a projecting portion protruding from the second wing member between them, for example by changing it so that arm support projections 16 and 17 are interposed between the first cam portion 22 and second cam portion 23.
Further, Exhibit Ko 4 discloses only a configuration in which, similarly to the invention in Exhibit Ko 3, a pair of support portions is provided on the configuration (support member 60) corresponding to the second wing member of Invention 1 at issue, with the configuration (mounting member 50) corresponding to the first wing member of Invention 1 at issue interposed between them. It contains no description suggesting a change to the configuration of the invention in Exhibit Ko 3.
