H01B CABLES; CONDUCTORS; INSULATORS; SELECTION OF MATERIALS FOR THEIR CONDUCTIVE, INSULATING OR DIELECTRIC PROPERTIES (selection for magnetic properties H01F1/00; waveguides H01P )
Description
H01B covers the design, manufacture, and material composition of cables, conductors, and insulators used in electrical systems. This includes bare and insulated wires, multi-conductor cables, coaxial cables, and fiber optic cables, as well as the selection and properties of materials chosen for their electrical conductivity, insulation capability, or dielectric characteristics. The subclass encompasses manufacturing processes specific to cable and conductor production, protective coverings, and mechanical properties of these components. Adjacent classes H01C (resistors) and H01D (electromagnets) are excluded, as are finished apparatus that incorporate these elements.
Filing statistics
CPC subclass H01B recorded 140,018 patent applications worldwide between 2013 and 2023. Annual filings grew from 10,354 in 2013 to 11,276 in 2023 (+9%), peaking at 15,902 applications in 2016. The most active applicants in class H01 are SAMSUNG ELECTRONICS COMPANY (37,897 applications), TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY (36,116 applications) and APPLIED MATERIALS (21,640 applications).
