Company patents
TOPPAN PRINTING CO., LTD.
TOPPAN PRINTING CO., LTD. appears to be undergoing a significant strategic shift, with patenting activity in its historically dominant categories like Layered Products (Laminates, Films) and Optical Elements & Systems, both representing 21.7% of its portfolio, showing sharp declines of -70.0% and -77.8% respectively in 2025. This trend is even more pronounced in Batteries & Fuel Cells, which saw an 84.6% decline in 2024 and a 100.0% decline so far in 2026, suggesting a broad de-emphasis across several core areas.
