ELECTRICITY
Class:
ELECTRIC TECHNIQUES NOT OTHERWISE PROVIDED FOR

Description

H05 covers electric techniques and equipment that do not fit within the more specialized electrical and electronics classes (H01-H04). This catch-all classification includes electrostatic phenomena, electric heating and cooking devices, X-ray generation equipment, nuclear reactor control systems, and other specialized electrical applications. The class serves as a residual category for electrical inventions that lack sufficient technical coherence or volume to warrant a dedicated class, ensuring comprehensive coverage of the IPC electrical spectrum.

Filing statistics

IPC H05 recorded 1,105,033 patent applications worldwide between 2013 and 2023, summed across its 6 subclasses. Annual filings grew from 67,642 in 2013 to 130,810 in 2023 (+93%), peaking at 134,903 applications in 2021. The most active applicants in class H05 are SAMSUNG ELECTRONICS COMPANY (7,201 applications), PANASONIC INTELLECTUAL PROPERTY (6,828 applications) and SEMICONDUCTOR ENERGY LABORATORY COMPANY (3,988 applications).
