Unlike the first-instance Tokyo District Court judgment, 2021 (Wa) 11507,
the court held that, based on the specification and general knowledge, the claim language “made of resin” means “synthetic resin” and cannot be interpreted as “synthetic fiber.”
⇒ Claim limitation not satisfied. Doctrine of equivalents also rejected.
