CHINA UNIVERSITY OF PETROLEUM-BEIJING
CHINA UNIVERSITY OF PETROLEUM-BEIJING's patent strategy shows a strong, albeit fluctuating, focus on energy-related technologies, with Drilling & Mining representing 36.2% of its portfolio and experiencing a significant 57.1% growth in 2025 before a -45.5% decline so far in 2026. Surprisingly, despite its name, the university also demonstrates an emerging interest in Electronic Design Automation (CAD/EDA), which saw a notable increase to 3 patents so far in 2026 after a -100.0% decline in 2025, suggesting a diversification beyond traditional petroleum-related fields.
