Company patents

TOYOCOLOR CO., LTD.

TOYOCOLOR CO., LTD. exhibits a surprising dual focus, with a strong emphasis on traditional 'Coating Compositions (Paints, Inks)' (49.3% of its portfolio) alongside a significant and growing commitment to 'Batteries & Fuel Cells' (36.6% of its portfolio), which saw a 66.7% year-over-year growth in 2025. While core materials categories like 'Non-metallic Inorganic Compounds' also experienced rapid growth of 300.0% in 2025, the company appears to be shifting away from 'Printers & Typewriters', which saw a 100.0% decline in 2024, and 'Polymer Synthesis (Polymerization)', with no patents in 2025 or so far in 2026.
