Company patents
CENTRAL SOUTH UNIVERSITY
CENTRAL SOUTH UNIVERSITY's patent strategy reveals a strong, albeit fluctuating, focus on materials science, with Alloys representing the largest share at 16.3% of its portfolio, despite a recent decline of -45.5% in 2025 and -33.3% so far in 2026. While many materials categories saw declines in 2025 and 2026, the university shows an interesting emerging interest in Electronic Design Automation (CAD/EDA), which saw a 50.0% growth so far in 2026, contrasting with the general slowdown in other areas.
