Company patents
DUK SAN NEOLUX CO., LTD.
DUK SAN NEOLUX CO., LTD. demonstrates a primary focus on Organic Electronics (OLED), accounting for 82.9% of its portfolio, with a significant surge in 2024 (YoY +105.6%) before a slight decline in 2025 and a partial decline so far in 2026. Surprisingly, despite its display focus, the company also holds a substantial 55.8% of its portfolio in Heterocyclic Compounds (Pharma), which has seen a consistent decline in patenting activity since 2023, indicating a potential shift away from this area.
