Company patents
Tokuyama Corporation
Tokuyama Corporation's patent strategy reveals a surprising, albeit potentially shifting, focus on Semiconductor Manufacturing Process, which saw an explosive 216.7% YoY growth in 2024, despite a subsequent decline in 2025 and so far in 2026. While core materials categories like Non-metallic Inorganic Compounds (24.7% of portfolio) and Polymer Additives (18.9% of portfolio) remain significant, the rapid growth in Cement & Ceramics (YoY +120.0% in 2025) suggests an emerging priority in construction materials, contrasting with a clear decline in Polymer Synthesis (Polycondensation), which saw a -71.4% YoY drop in 2025.
