Company patents
KOA CORPORATION
KOA CORPORATION's patent strategy reveals a surprising shift away from its largest category, Electrical Measurement, which constitutes 23.5% of its portfolio but has seen a significant decline of 71.4% so far in 2026. While there was an emerging focus in Printed Circuits & Electronic Assemblies with a 200.0% YoY growth in 2025, the complete absence of patents in this category and several others (Alloys, Temperature Measurement, Semiconductor Packaging & Encapsulation, Force / Pressure Measurement) so far in 2026 suggests a broad re-evaluation of its R&D priorities.

Devices and methods for accurately measuring or monitoring electrical current draw and power usage in various systems, often for control, optimization, or safety purposes.
Methods and devices for integrating temperature sensors directly into materials, structures, or challenging environments (e.g., hydrogen tanks, concrete, ocean) to measure internal or localized temperatures.
Methods and compositions for applying metallic or alloy layers to a substrate, or modifying the surface of an alloy, to impart specific functional properties such as corrosion resistance, wear resistance, electrical insulation, or improved adhesion, without altering the bulk properties significantly.
Innovations in the construction, integration, and operational verification of flow measurement devices, including methods for calibration, fault detection, and structural integrity monitoring.
Techniques and apparatus for electrically testing semiconductor devices, integrated circuits, or wafers during manufacturing or post-assembly, including built-in self-test (BIST) and contact reliability assessment.
Methods and structures for integrating and enclosing electronic components into compact, multi-functional modules, often involving embedded components, multi-layer substrates, and electromagnetic shielding for performance and miniaturization.
Aluminum-based alloys developed for applications requiring low density combined with high strength, ductility, and formability, often involving specific alloying elements (e.g., Li, Mg, Si, Mn) and controlled aging or thermomechanical treatments.
Manufacturing processes and material compositions for creating electronic circuits on flexible or conformable substrates, enabling novel form factors, enhanced durability, and new applications beyond rigid PCBs.
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.
Technologies for measuring the flow rate, level, or composition of mixtures containing multiple fluid phases (e.g., liquid-liquid, liquid-gas, liquid-solid suspensions), often employing specialized sensing principles to differentiate components.
Measures force or pressure by detecting changes in electrical capacitance. This typically involves the deformation of a dielectric material or the relative movement of conductive plates, altering the distance or area between them.
Sensors and systems designed to detect and quantify localized contact forces, pressure distribution, or touch interactions, often employed in robotics, human-machine interfaces, or object manipulation applications.
Techniques for measuring, monitoring, and compensating for temperature variations within semiconductor devices, integrated circuits, or photonic components to maintain performance, prevent degradation, and ensure reliability across operating conditions.
Temperature sensing systems integrated into wearable devices or medical apparatus for monitoring physiological conditions, such as inflammation detection, often utilizing differential temperature measurements.
