Company patents
DOWA METALTECH CO., LTD.
DOWA METALTECH CO., LTD.'s patent strategy shows a surprising shift away from core semiconductor areas, with categories like Semiconductor Packaging & Encapsulation, Switches, and Semiconductor Manufacturing Process all experiencing significant declines of -75.0% to -100.0% in 2025 and so far in 2026. While Alloys remain their largest category at 28.3% of the portfolio, the company appears to be exploring new material applications, as evidenced by the rapid 300.0% YoY growth in Layered Products (Laminates, Films) in 2024, despite a subsequent decline.
