Company patents
SHANGHAI DIANBA NEW ENERGY TECHNOLOGY CO., LTD.
SHANGHAI DIANBA NEW ENERGY TECHNOLOGY CO., LTD. exhibits a strong, albeit recently decelerating, focus on core automotive electrification technologies, with Electric Vehicle Propulsion (84.6% of portfolio) and Batteries & Fuel Cells (52.3% of portfolio) seeing significant patenting activity in 2024 (YoY +68.8% and +90.0% respectively), before a sharp decline in 2025 and so far in 2026. The company also shows a surprising, though minor, interest in Locks & Keys (10.8% of portfolio), which experienced a 100.0% YoY growth in 2024 before a subsequent decline.
