Introduced: September 1968
Classification Context
- Section:
- ELECTRICITY
- Class:
- GENERATION, CONVERSION, OR DISTRIBUTION OF ELECTRIC POWER
- Subclass:
- BOARDS, SUBSTATIONS OR SWITCHING ARRANGEMENTS FOR THE SUPPLY OR DISTRIBUTION OF ELECTRIC POWER
Description
H02B covers electrical equipment and installations that organize and manage power distribution from generation sources to end users. This includes control boards, switchboards, substations, switching apparatus, and their associated structural frameworks and components used in power supply networks. The classification encompasses both indoor and outdoor installations, protective devices, and the arrangement of conductors and equipment within these distribution systems. Adjacent classes H02G (wiring, cabling) and H02M (conversion of electric power) handle transmission infrastructure and power conversion separately.
Filing statistics
IPC subclass H02B recorded 228,580 patent applications worldwide between 2013 and 2023. Annual filings grew from 7,630 in 2013 to 31,374 in 2023 (+311%), peaking at 36,869 applications in 2020. The most active applicants in class H02 are SGCC(STATE GRID CORPORATION OF CHINA) (54,496 applications), MITSUBISHI ELECTRIC CORPORATION (10,495 applications) and TOYOTA MOTOR CORPORATION (9,464 applications).
