Company patents
KANSAI PAINT CO., LTD.
KANSAI PAINT CO., LTD's patent strategy, while heavily focused on its core "Coating Compositions (Paints, Inks)" (76.1% of portfolio), shows a surprising emerging focus in "Plastics Shaping & Molding," which saw a remarkable 300% year-over-year growth in 2025 with 4 patents, indicating a potential diversification beyond traditional coatings. However, patenting activity across most categories, including the dominant "Coating Compositions," appears to be significantly declining so far in 2026, with a 73.9% drop in the latter, suggesting a potential shift in R&D or filing priorities.
