Company patents
Unger Marketing International, LLC
Unger Marketing International, LLC's patent strategy appears to be undergoing a significant shift, with a strong historical focus on Domestic Cleaning Devices, which represent 44.6% of its portfolio and saw a remarkable 116.7% YoY growth in 2024. However, a surprising trend is the widespread decline across nearly all categories in 2025, with many experiencing 100% YoY drops, suggesting a potential re-evaluation or consolidation of its R&D efforts, as evidenced by only 1 patent filed so far in 2026.

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.
Systems for storing, heating, pumping, and precisely dispensing water or cleaning solutions within domestic appliances or cleaning tools. This includes cartridge-based systems, dissolvable cleaning agents, and controlled fluid delivery for optimal cleaning performance.
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.
Systems and mechanisms that allow autonomous cleaning robots or devices to return to a base station for automated tasks such as mop washing, dustbin emptying, fluid replenishment, or cleaning of tool heads without human intervention.
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.
Design and control of advanced robotic grippers, tools, and mechanical linkages for specific manipulation tasks or operating in challenging environments.
Systems specifically engineered to use sprayed liquids or aerosols for cleaning surfaces, removing residues, or distributing disinfectants in various environments.
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.
Systems and processes for applying coatings, films, or materials onto surfaces in manufacturing or industrial contexts, often involving automated movement, surface preparation, or post-application treatment.
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.
