Company patents
Unicharm Corporation
Unicharm Corporation's patent strategy reveals a surprising and strong focus on "Animal Husbandry / Fishing," which constitutes 42.2% of its portfolio, despite a notable 50.0% decline in patenting activity so far in 2026. Concurrently, its significant investment in "Implants & Prosthetics" (32.5% of portfolio) appears to be a shifting priority, experiencing a sharp 71.4% year-over-year decrease in 2026, while patenting in "Layered Products (Laminates, Films)" has completely ceased in 2026 after consistent declines.

Development and application of textile materials with engineered properties such as waterproofing, thermal regulation, anti-cling, structural coloration, or enhanced filtration capabilities for specific performance needs.
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.
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.
Design and material innovations for specific cleaning components or attachments, such as brush rolls, mop pads, scrapers, or multi-functional surface tools. These are often tailored for particular surfaces, debris types, or cleaning tasks to enhance effectiveness.
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.
Thin, multi-layered films and structures specifically designed for electronic applications, including flexible substrates for devices, display panel components, and active material layers for battery electrodes.
Methods and apparatus for disinfecting or sterilizing medical devices, waste, or environments, often employing radiation, chemical agents, or thermal processes, and including monitoring systems.
Innovations in vacuum cleaner components and systems for efficiently separating, compacting, and containing collected dust, dirt, or lint. This often involves multi-stage filtration, cyclonic separation, or specialized disposal mechanisms to improve air quality and ease of maintenance.
Design features and accessories that improve the installation, storage, usability, and overall user experience of household cleaning appliances and manual tools. This includes mounting brackets, ergonomic handles, and integrated storage solutions.
