Company patents

Harbin Engineering University

Harbin Engineering University's patent strategy shows a surprising recent shift, with a significant decline across many categories in 2025 and so far in 2026, including a 71.4% YoY drop in Machine Testing and a 66.7% decline in Radar / Sonar / Lidar in 2025. While Electronic Design Automation (CAD/EDA) remains their largest category at 15.6% of their portfolio, its patenting activity also saw a 50.0% decline in 2025, suggesting a broad re-evaluation of their patenting priorities, with the notable exception of Machine Learning & AI, which has seen 2 patents so far in 2026 after no activity in 2024-2025.
