Company patents
HACH COMPANY
HACH COMPANY's patent strategy is heavily concentrated in Material & Chemical Analysis, which accounts for 81.2% of its portfolio, showing consistent growth with a 10.5% YoY increase in 2025, though patenting activity so far in 2026 is down significantly by 71.4%. Surprisingly, despite its core focus, the company has seen a complete cessation of patenting in Wireless Networks and Heterocyclic Compounds (Pharma) in 2025 and so far in 2026, indicating a clear shift away from these areas.

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.
Methods and compositions for identifying, quantifying, or characterizing specific biological molecules (e.g., nucleic acids, proteins, metabolites, antibodies) or microbial species, often for diagnostic, prognostic, or quality control applications.
Techniques and systems for precisely measuring electrical or electromagnetic properties of materials or components, often involving specialized resonators, waveguides, or multi-range measurement systems to ensure accuracy.
Specific techniques and materials developed to remove persistent or difficult-to-treat pollutants from water, such as per- and polyfluoroalkyl substances (PFAS), micropollutants, or specific industrial chemicals.
Non-chemical or non-biological methods that alter the physical properties or structure of water, often claimed to improve its quality or interaction with biological systems, such as vortexing or electromagnetic treatment.
Innovations in nozzle internal geometry, actuation, or multi-fluid mixing to achieve specific spray patterns, droplet sizes, or performance characteristics, especially for challenging fluids or conditions.
Integration of sensors, data processing, and control systems to assess the effectiveness of a cleaning process, detect contaminants, measure cleaning agent delivery, and optimize operational parameters for efficiency and thoroughness.
Technologies for removing contaminants from critical surfaces of sensors, vehicle parts, or industrial components, often involving automated or semi-automated processes. This can include physical, acoustic, or fluid-based methods to maintain functionality.
Processes that use strong oxidants, electrochemical methods, sonic waves, or other energy-intensive techniques to break down organic pollutants, disinfect water, or facilitate contaminant separation.
Membrane-based separation for water purification, contaminant removal, desalination, and wastewater treatment, including reverse osmosis, ultrafiltration, and forward osmosis modules.
Systems and methods specifically engineered for removing pollutants and impurities from water sources, ranging from groundwater decontamination to point-of-use filtration, often employing adsorption, membrane, or distillation techniques.
Systems and methods for accurately controlling the volume, location, and characteristics of sprayed fluids, often involving sensors, feedback, or specific nozzle geometries for precise application.
Methods for treating solid or semi-solid waste (sludge, litter, industrial byproducts) from water treatment processes, often with a focus on reducing volume, detoxifying, or recovering valuable resources like energy (biogas), chemicals, or materials.
Systems and methods for transferring electrical energy without physical contact, often utilizing inductive or resonant coupling, including antenna design, resonance tracking, and control mechanisms for efficient power delivery.
Membrane and depth filtration for industrial separation, gas purification, and bioprocess clarification including cross-flow, dead-end, tangential flow filtration, and oil/water separation.
