Company patents
Putzmeister Engineering GmbH
Putzmeister Engineering GmbH's patent strategy reveals a surprising, albeit fluctuating, focus on "Pumps (Positive Displacement)" which constitutes 21.3% of its portfolio and saw a significant 200.0% YoY growth in 2024, followed by a 50.0% increase so far in 2026. While maintaining a steady presence in "Additive Manufacturing (3D Printing)" (9.8% of portfolio), the company appears to be shifting priorities away from categories like "Valves" and "Pipes & Tubing," both experiencing a 100.0% YoY decline in 2025 and no patents so far in 2026.
