H05 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
CPC H05 recorded 670,750 patent applications worldwide between 2013 and 2023, summed across its 6 subclasses. Annual filings grew from 48,933 in 2013 to 61,054 in 2023 (+25%), peaking at 71,121 applications in 2020. The most active applicants in class H05 are SAMSUNG ELECTRONICS COMPANY (9,981 applications), SAMSUNG DISPLAY (5,041 applications) and LG ELECTRONICS (4,742 applications).
