KYUSHU UNIVERSITY, NATIONAL UNIVERSITY CORPORATION

KYUSHU UNIVERSITY NATIONAL UNIVERSITY CORPORATION's patent strategy reveals a surprising and strong emerging focus on 'Material & Chemical Analysis', which has seen a remarkable 133.3% year-over-year growth so far in 2026, alongside a significant 400.0% surge in 'Pharmaceutical Preparations' patents in 2024, now representing 15.2% of its portfolio. While maintaining a strong presence in pharma, the university appears to be shifting priorities away from 'Functional Materials (LCD, Lubricants)', which has declined by 85.7% so far in 2026, and 'Organic Electronics (OLED)', which saw a sharp 63.6% decline in 2025 after a massive 1000.0% increase in 2024.
