Company patents
Northvolt AB
Northvolt AB's patent strategy is overwhelmingly focused on Batteries & Fuel Cells, which constitutes 89.1% of its portfolio and saw significant growth of +233.3% in 2024 and +35.0% in 2025, indicating a strong commitment to this core area despite a partial decline of -85.2% so far in 2026. While other categories like Electrical Measurement and Power Distribution & Storage show shifting priorities with recent declines, the company's emerging focus on Compounds Containing Metals, though small at 4.7% of the portfolio, suggests an interest in underlying material science for battery innovation.
