Company patents
Mueller International, LLC
Mueller International LLC's patent strategy reveals a significant shift away from its core Pipes & Tubing (41.3% of portfolio) and Valves (26.9% of portfolio) categories, which saw substantial declines of -59.4% and -50.0% respectively in 2025, suggesting a re-evaluation of traditional product lines. Surprisingly, despite a broad decline across many categories in 2024, the company showed an emerging focus on Machine Testing, with a 33.3% increase in patent filings so far in 2026, indicating a potential pivot towards quality assurance or diagnostic technologies within manufacturing.

Mechanisms allowing rapid, secure, and often sealed attachment and detachment of pipes, tubes, or hoses, frequently featuring locking, sealing, and release components for efficient assembly and maintenance.
Connectors, seals, and tubing solutions specifically designed for pipes, ducts, or conduits that deviate from standard circular cross-sections, or require flexible/collapsible forms for specific applications or installation challenges.
Systems and methods for repairing, reinforcing, or isolating existing pipes, often involving internal lining, curing processes, or sealing techniques without extensive excavation or replacement.
Couplings and fittings designed for specific fluid properties (e.g., cryogenic, chemical, medical, high-pressure) or requiring aseptic conditions, low-spill characteristics, or antimicrobial features to ensure safety and integrity.
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.
Innovations in the construction, integration, and operational verification of flow measurement devices, including methods for calibration, fault detection, and structural integrity monitoring.
Incorporating sensors and processing capabilities directly into valve systems to monitor operational state, detect malfunctions, measure flow parameters, or verify proper installation.
Specialized valve designs for domestic and commercial applications involving water distribution, temperature control, and air conditioning, often focusing on integration, materials, and specific flow characteristics.
Valves engineered to automatically open or close based on pressure differentials, preventing over-pressurization, controlling flow direction, or suppressing backflow in fluid systems.
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.
Valves specifically designed for managing fluid power in hydraulic or pneumatic systems, including components for pressure regulation, flow direction, and system centering.
Tubes, hoses, or ducts incorporating additional components or features beyond simple fluid conveyance, such as embedded electronics (sensors, heaters), structural reinforcement, or segregated compartments for cable routing.
Design and manufacturing techniques for incorporating antenna structures directly into electronic devices, product housings, or materials, often under constraints of space, aesthetics, or environmental factors.
Tools and systems engineered for the precise installation, removal, or manipulation of specific components or fasteners, often involving specialized gripping, depth control, or extraction mechanisms.
Antennas engineered to operate effectively across a wide continuous range of frequencies (broadband) or multiple distinct frequency bands, often requiring specific radiating element geometries or impedance matching circuits.
Systems and methods for electronically steering or shaping antenna beams by controlling the phase and amplitude of signals fed to individual elements in an array, including calibration techniques and multi-antenna configurations.
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.
Systems and sensors designed to measure the pressure difference between two distinct points or to capture rapid, transient pressure fluctuations in fluid or gas systems, often using diaphragms or pistons.
Systems and methods that use sensors, data analysis, and automation to monitor water quality, process parameters, or system performance, enabling adaptive control, predictive maintenance, or incentive-based management.
Systems that leverage networked sensors, cloud platforms, and data analytics to remotely monitor the operational status, detect anomalies, and diagnose faults in distributed assets or infrastructure.
Techniques and structures used to reduce unwanted electromagnetic coupling, scattering, or interference between multiple antennas, different frequency bands, or sensitive electronic components within a device.
Integration of sensors, microcontrollers, and communication modules into hand tools to enable precise operation, remote configuration, and user guidance through real-time feedback or augmented reality.
Fasteners designed to release or change state under specific triggers, such as a predefined force, pressure differential, or through active mechanical control.
Technologies for measuring the flow rate, level, or composition of mixtures containing multiple fluid phases (e.g., liquid-liquid, liquid-gas, liquid-solid suspensions), often employing specialized sensing principles to differentiate components.
