Tokyo District Court, Reiwa 5 (Wa) 70449 [Fastening hardware] <Presiding Judge Takahashi>
The claim wording “for inducing deformation when an excessive load acts” does not limit the invention's configuration.
“It merely indicates the purpose to be achieved, or the effects inevitably obtained, by a configuration integrating the front portion and rear edge portion with multiple branch-like portions, and has no meaning limiting the invention's configuration.”
⇒ Lacks novelty over a design publication.
“The multiple narrow plate portions of the column-connecting fitting in the Ko 5 invention have the same shape configuration as the multiple branch-like portions of the claimed fastening hardware, and therefore inevitably produce the effects expressed as ‘for inducing deformation when an excessive load acts.’”
