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
IPC subclass H01B recorded 250,733 patent applications worldwide between 2013 and 2023. Annual filings grew from 18,984 in 2013 to 23,641 in 2023 (+25%), peaking at 26,842 applications in 2020. The most active applicants in class H01 are TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY (43,574 applications), SAMSUNG ELECTRONICS COMPANY (42,206 applications) and LG CHEM (21,383 applications).
