Company patents
NOF CORPORATION
NOF Corporation's patent strategy reveals a strong, sustained focus on "Pharmaceutical Preparations," which constitutes 38.9% of its portfolio and saw a significant 41.7% YoY growth in 2025, indicating an emerging commitment despite a partial decline so far in 2026. While traditionally strong in "Polymer Synthesis (Polycondensation)" (30.5% of portfolio), the dramatic 87.5% decline in 2026 suggests a shifting priority, contrasting with the earlier rapid growth in "Polymer Synthesis (Polymerization)" which surged by 175.0% in 2024.
