January 21,2022

DOE (Doctrine of Equivalence)

(Conclusion)
DOE (Doctrine of Equivalence) is Not admitted.
=Appealed case <IP High Court> 2020 (Ne) 10041 affirmed this.

Since the defendant’s system does not transmit one piece of information created on the basis of two pieces of information, i.e., ticket information and ticket issuance information, to the terminal, the defendant’s system does not exhibit the same operation and effect as the operation and effect of the present invention in that the burden on the communication line, the storage capacity, and the processing speed of the terminal are reduced by half as compared with the system in which the ticket information and ticket issuance information are transmitted to the terminal, respectively.
