Company patents
CNPC USA CORPORATION
CNPC USA Corporation's patent strategy reveals a strong, albeit fluctuating, focus on its core energy sector, with Drilling & Mining representing 70.7% of its portfolio. Surprisingly, despite its energy focus, Functional Materials (LCD, Lubricants) also constitutes a significant 52.2% of its portfolio, experiencing a remarkable 162.5% YoY growth in 2024 before a decline in 2025, suggesting a dynamic and potentially shifting emphasis within its materials science applications, while several smaller categories like Polymer Additives and Batteries & Fuel Cells show a clear decline in priority with zero patents so far in 2026.
