Company patents
Valmet Technologies Oy
Valmet Technologies Oy's patent strategy reveals a surprising focus on Material Handling (Sheets, Webs), which accounts for 13.7% of its portfolio and saw a significant 66.7% growth in 2024, indicating a sustained interest despite a dip in 2025. While Separation Processes (Filtration, Distillation) represents 11.0% of its patents, the complete absence of filings so far in 2026 suggests a potential shift in priorities for this area.

Systems and methods for precisely measuring, monitoring, and regulating the longitudinal tension in continuous webs of material during roll-to-roll processes to prevent defects, reduce waste, and ensure consistent product quality.
Apparatus and methods for automatically winding or unwinding continuous materials such as webs, cables, conduits, or yarns onto or from spools, reels, or bobbins, including aspects like layering, coreless winding, and material supply.
Systems that perform operations like cutting, folding, binding, or applying liquids to sheets or webs, often integrated within larger production lines such as printing or image forming apparatuses.
Novel designs and configurations for heat exchangers that improve heat transfer efficiency, compactness, or enable specific phase change or separation processes within refrigeration and heat pump cycles.
Techniques and structures within heat exchangers designed to enhance heat transfer efficiency by controlling and optimizing fluid flow, including baffle arrangements, jet impingement, and condensate management.
Membrane and depth filtration for industrial separation, gas purification, and bioprocess clarification including cross-flow, dead-end, tangential flow filtration, and oil/water separation.
Technologies and systems for removing unwanted components or separating desired gases from a mixed gas stream, including adsorption, absorption, and membrane-based methods.
Heat transfer devices that utilize the phase change of a working fluid (evaporation and condensation) to efficiently move heat, often incorporating capillary structures, heat pipes, or vapor chambers.
Technologies for maintaining the correct path and alignment of webs or individual sheets during conveyance, including mechanisms for steering, correcting positional deviations, and managing static electricity.
Methods and systems for uniquely identifying individual units of material (e.g., yarn spindles, winding spools, bobbins) and monitoring their performance or status within a material handling process, often using sensors and coding.
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.
Techniques for combining multiple materials or layers, often with specialized surface treatments, coatings, or assembly methods, to create functional or aesthetically enhanced plastic articles, including consumer goods and encapsulated electronics.
Methods and tooling for forming structural components from fibrous materials impregnated with resin, involving processes like prepreg handling, resin infusion, and co-bonding during curing.
