Company patents
DALIAN UNIVERSITY OF TECHNOLOGY
Dalian University of Technology's patent strategy reveals a surprising shift away from core computing areas, with Electronic Design Automation (CAD/EDA) declining by 45.5% in 2025 and Image Processing by 64.3% in the same year. While Material & Chemical Analysis remains a significant focus (8.5% of portfolio), the dramatic 500.0% growth in Additive Manufacturing (3D Printing) in 2025 suggests an emerging priority in advanced manufacturing technologies, despite a sharp decline so far in 2026.
