Tokyo District Court, 2005 (Wa) 14346 [Top-Level Setting Aid] <Ichikawa>
The accused product integrated the two configurations of claim elements B and D2.
⇒ (1) The claims do not exclude an integrated structure. + (2) No evidence shows a different mechanism for solving the problem (restraining force).
⇒ Claim limitations satisfied
Cf. Osaka District Court, 1998 (Wa) 7191
(Excerpts from the court's reasoning)
Claim element B2 of Invention 1 states that “an upper wing portion 2 extending horizontally and perpendicular to the aid body 1 is fixed to the upper portion of the aid body 1,” while element D2 states that “a lower wing portion 3 extending …vertically and perpendicular to the aid body 1 is fixed to the lower portion.” The wording does not exclude a lower wing portion 7 positioned directly beneath and integrated with upper wing portion 2….
There is insufficient evidence to establish that the mechanism generating the restraining force asserted by the defendant differs depending on whether upper wing portion 2 and lower wing portion 7 are integrated….
Translator’s notes (editorial)
The summary names element B, whereas the quoted judgment names B2. Both source labels are preserved.
