Represented Daio Paper Corporation in successfully defending against patent infringement claims brought by Nippon Paper Crecia at the Tokyo District Court. The dispute centred on Daio's extra-long toilet-paper rolls (3.2 times longer than conventional products), which Crecia alleged infringed its three patents related to surface texturing technology. The court ruled in August 2024 that Daio's specifications fell outside Crecia's patent scope.
