Company patents
NATIONAL UNIVERSITY CORPORATION HOKKAIDO UNIVERSITY
NATIONAL UNIVERSITY CORPORATION HOKKAIDO UNIVERSITY's patent strategy reveals a strong and sustained focus on pharmaceutical innovation, with 'Pharmaceutical Preparations' constituting 23.3% of its portfolio and 'Therapeutic Activity (Pharma)' at 16.2%, both showing consistent growth in recent years. While there's an emerging focus on 'Powder Metallurgy' with a remarkable +300.0% YoY growth in 2026 so far, the significant decline in 'Material & Chemical Analysis' (-100.0% YoY in 2026 so far) and 'Catalysts & Reactors' (-80.0% YoY in 2026 so far) suggests a shifting priority away from broader materials science.
