Company patents
TOPPAN INC.
TOPPAN Inc.'s patent strategy reveals a surprising shift away from its core 'Layered Products (Laminates, Films)' category, which, despite being 22.5% of its portfolio, has seen a 50.0% decline in patent filings so far in 2026 after a 35.5% drop in 2025. While many categories show recent declines, the company appears to be exploring 'Functional Materials (LCD, Lubricants)', which saw a 100.0% growth in 2025, and 'Pictorial / Video Communications', which rebounded with a 100.0% growth so far in 2026 after a sharp decline in 2025.
