Company patents
North China Electric Power University
North China Electric Power University's patent strategy is surprisingly broad, with a significant 14.9% of its portfolio in non-core areas like Business Methods & Fintech and Electronic Design Automation (CAD/EDA), despite its name suggesting a focus on power. While Power Distribution & Storage remains its largest category at 52.1% of its portfolio, the university has shown a notable, albeit fluctuating, interest in Wind Motors / Turbines, experiencing a +266.7% YoY growth in 2024, and a recent resurgence in Machine Learning & AI with 3 patents so far in 2026 after a sharp decline.
