Company patents
IUCF-HYU (INDUSTRY-UNIVERSITY COOPERATION FOUNDATION HANYANG UNIVERSITY)
IUCF-HYU's patent strategy reveals a strong, sustained focus on Batteries & Fuel Cells, which constitutes 11.5% of its portfolio and saw a significant 150.0% YoY growth in 2024, despite a partial decline of 38.1% so far in 2026. While Memory Devices (Structural) also experienced a remarkable 375.0% YoY surge in 2024, the sharp decline in Wireless Networks (down 83.3% in 2025 and 50.0% so far in 2026) indicates a clear shift away from this area, alongside a surprising complete halt in Speech Processing and Electric Motors & Generators patenting so far in 2026.
