Company patents
KSB SE & Co. KGaA
KSB SE & Co. KGaA's patent strategy is heavily concentrated in "Pumps (Centrifugal)", representing 66.7% of its portfolio, which saw a significant surge in 2024 with a 111.1% YoY growth before stabilizing in 2025 and a partial decline so far in 2026. Surprisingly, despite its core focus, the company shows a recent, albeit small, emerging interest in "Valves" with 3 patents in 2025, while categories like "Additive Manufacturing (3D Printing)" and "Machine Testing" have seen a sharp decline in patenting activity in 2026, indicating a potential shift away from these areas after a brief focus in 2024-2025.

Pumps and blowers specifically adapted or designed for unique fluid types, challenging environments, or particular industrial, medical, or consumer applications, often involving debris, specific gas mixtures, or precise delivery requirements.
Focuses on optimizing the geometry, structure, and internal flow channels of impellers, blades, and housings to improve fluid dynamics, efficiency, or specific performance characteristics of centrifugal pumps and fans.
Methods and components for converting power into mechanical motion to drive pump mechanisms, encompassing electric motors, hydraulic actuators, and specialized motion converters like ball screws or solenoids.
Innovations in the design, materials, and maintenance of seals, valves, and related components to improve durability, reduce leakage, and enable specific pump functions like high-pressure operation or automated seal replacement.
Systems and methods for monitoring, regulating, and diagnosing the performance and health of pumps and fans, including speed control, flow rate management, abnormality detection, and safety mechanisms like overspeed safeguards.
Development of novel motor architectures beyond traditional radial flux designs, including linear, axial, or multi-armature configurations, often to optimize for specific performance characteristics like torque density or form factor.
Mechanisms and control systems for precisely moving valve elements, often involving electric motors, cams, solenoids, or pneumatic/hydraulic pilots, to achieve desired flow or position.
Valves engineered to automatically open or close based on pressure differentials, preventing over-pressurization, controlling flow direction, or suppressing backflow in fluid systems.
Utilizing sound and vibration analysis to detect malfunctions, assess balance, or monitor the operational health of machinery and structures. This often involves sensors, signal processing, and pattern recognition.
Utilizing sensor data, historical performance, and analytical models to anticipate equipment failures, diagnose faults, and estimate remaining useful life, thereby enabling proactive maintenance and reducing downtime.
Methods and circuits for controlling the power electronic converters (inverters, bridges) that supply current and voltage to electric motors, including switching strategies, voltage command generation, and multi-phase configurations.
Methods and systems for detecting fluid or gas leaks, or assessing the quality and continuity of seals in containers, systems, or structures. This often involves pressure changes, electrical properties, or acoustic analysis.
Integration of electric motors into larger systems (e.g., vehicles, power tools) and safety features for high-voltage components, including control interfaces, mechanical integration, and environmental protection (e.g., waterproofing).
Techniques for building three-dimensional metal objects layer-by-layer using metal powders, including powder bed fusion, binder jetting, and directed energy deposition. This theme encompasses process mechanics, equipment design, and operational control for AM systems.
Computational methods and design principles for generating optimized geometries, internal structures (e.g., lattices, minimal surfaces), or functional features that are specifically enabled or enhanced by the capabilities of additive manufacturing.
Integration of additive manufacturing with subtractive manufacturing (e.g., machining, cutting) or other traditional processes within a single system or workflow to create parts with improved features, surface finish, or material properties, or to enable new manufacturing paradigms.
Sophisticated software or hardware-implemented control strategies that optimize motor performance, such as precise speed/torque regulation, vibration reduction, or efficiency, often using model-based, predictive, or adaptive techniques.
Techniques for determining the rotor position, speed, or other operational parameters of an electric motor without dedicated physical sensors, often relying on back-EMF, current, or voltage measurements.
