Company patents
ElringKlinger AG
ElringKlinger AG's patent strategy reveals a strong, albeit volatile, commitment to "Batteries & Fuel Cells," which constitutes 58.8% of its portfolio and saw a significant 54.5% growth in 2025 before a -58.8% decline so far in 2026. Surprisingly, despite its core focus, the company is also rapidly expanding its "Vehicle Steering & Bodies" portfolio, which, while small at 7.1%, experienced a remarkable 200.0% growth in 2026, indicating an emerging focus on broader automotive structural components.
