Company patents
FUJIMORI KOGYO CO., LTD.
FUJIMORI KOGYO CO., LTD. appears to be undergoing a significant shift in its patent strategy, with a surprising and widespread decline across nearly all categories in 2025 and so far in 2026, including core areas like Layered Products (Laminates, Films) and Containers & Packaging, both seeing a -100.0% YoY decline in 2026. While Adhesives showed a strong +133.3% YoY growth in 2024, its subsequent -42.9% decline in 2025 and -100.0% in 2026 suggests a broad re-evaluation of R&D focus rather than a targeted shift to new emerging areas, with only Pharmacy Containers / Devices showing any patent activity (1 patent) so far in 2026.
