Osaka District Court, Case No. 2024 (Wa) 7055

[Taxi dispatch management system] (Presiding Judge Matsuami)

*Claim requirements not satisfied (the doctrine of equivalents also not established).

"Taxi (information)" in claim element C means individual vehicles (information about them).

⇒ A "dispatch confirmation request specifying the taxi desired by the user" in the invention means a request to dispatch the particular taxi selected by the user.

⇒ What the defendant's application displays on the user's terminal is a screen for "specifying a taxi company," not information about individual vehicles.

+ Since the user does not select a particular vehicle, it also lacks a "dispatch confirmation request specifying the taxi desired by the user."

(Quoted wording is translated.)
