Company patents
LIXIL Corporation
LIXIL Corporation's patent strategy reveals a surprising, albeit fluctuating, focus on "Locks & Keys," which accounts for 14.8% of its portfolio and saw a 100.0% YoY growth in 2024 and 2025 before a -75.0% decline so far in 2026. Concurrently, "Water / Sewage Treatment" is an emerging focus, showing a 200.0% YoY growth in 2024 and another 100.0% growth so far in 2026, indicating a renewed interest in this materials sector despite a dip in 2025.

Mechanical lock designs and components focused on resisting picking, unauthorized manipulation, forced entry, or other technical unlocking methods, often through complex internal mechanisms or robust materials.
Locking mechanisms specifically designed for automotive applications, recreational vehicles, or unique door types like bi-fold, sliding, or container doors, often incorporating specific safety, noise reduction, or operational features.
Locks integrating electronic components for remote control, wireless communication, internet connectivity, and digital credential management, often including features for user identification and access monitoring.
Membrane-based separation for water purification, contaminant removal, desalination, and wastewater treatment, including reverse osmosis, ultrafiltration, and forward osmosis modules.
Additives or compositions specifically formulated for surface application or modification to impart protective, decorative, or specialized functional properties to polymer products.
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.
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.
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.
Synthesis and modification of polysiloxane polymers to introduce specific functional groups or structures, enhancing properties for applications like composites, coatings, biomedical uses, or powder treatment.
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.
Development of materials with tailored porosity, surface chemistry, or structure, such as metal-organic frameworks (MOFs), zeolites, or superficially porous particles, for selective adsorption, ion exchange, or chromatographic separations.
Methods and devices for generating, transferring, storing, and utilizing electronic or digitally encoded keys and access credentials, including physical keys with integrated digital information for enhanced security or convenience.
Spraying devices designed to handle, mix, or independently dispense multiple distinct fluid components, often with mechanisms for selection, blending, or sequential application.
