Company patents
TOYOBO CO., LTD.
TOYOBO CO., LTD's patent strategy reveals a strong, albeit fluctuating, focus on core materials science, with Layered Products (Laminates, Films) and Polymer Working & Compounding together accounting for over 63% of its portfolio. While Polymer Working & Compounding saw a significant 37.0% YoY growth in 2025, the dramatic 84.0% decline in Layered Products (Laminates, Films) patents so far in 2026, alongside a 100.0% decline in Polymer Compositions and Containers & Packaging, suggests a broad re-evaluation or shift in priorities across several key areas, despite an emerging interest in Organic Electronics (OLED) which experienced a 300.0% YoY surge in 2024.
