IP High Court, Reiwa 5 (Gyo-Ke) 10100 [Gas-scrubber fluid purification apparatus] <Judge Shimizu>
The invention's technical significance lies in dividing functions between the scrubber body and the separation system through a “separate tank,” thereby reducing buildup, clogging, maintenance burdens, and waste volume.
By contrast, there was no motivation in the cited invention to provide a “buffer tank” separately from the “gas scrubber.”
⇒ Inventive step upheld.
