Company patents
NIPPON SHOKUBAI CO., LTD.
NIPPON SHOKUBAI CO., LTD. demonstrates a broad materials-focused patent strategy, with Catalysts & Reactors (24.0% of portfolio) and Polymer Synthesis (Polymerization) (22.1% of portfolio) as core areas. Surprisingly, despite its materials focus, the company showed a significant, albeit volatile, interest in Acyclic / Carbocyclic Compounds, with a 116.7% YoY growth in 2024, suggesting an exploration into pharmaceutical or biotech intermediates, though this has since declined. The sharp decline in Batteries & Fuel Cells (YoY -100.0% in 2026 so far) and Sterilization & Biocompatible Materials (YoY -100.0% in 2025) indicates a clear shift away from these areas after periods of activity.
