IP High Court, Reiwa 7 (Ne) No. 10074 [Reservation Management Device] <Presiding Judge Masuda>
*As at first instance, the doctrine of equivalents was rejected.
(Excerpt from the judgment; translated)
As stated in Section 5(2) of Part III of the “Facts and Reasons” of the cited original judgment, the configuration in which image data is transmitted from the reservation management device to the image printing device, triggered by operation of the store terminal, is an essential part of each invention at issue. Therefore, it cannot be said that only the timing asserted by the appellant is the essential part of each invention at issue. …
The configuration in which image data is transmitted from the reservation management device to the image printing device, triggered by operation of the store terminal, is an essential part of each invention at issue. Because the accused system does not include the invention-specifying matters of constituent requirements 7C-3 and 8D of each invention at issue, which contain this essential part as an element, it cannot be said to satisfy the first requirement of the doctrine of equivalents.
