H10D INORGANIC ELECTRIC SEMICONDUCTOR DEVICES
Description
H10D covers inorganic semiconductor devices and solid-state electronic components not classified elsewhere in section H10. This subclass encompasses a broad range of semiconductor technologies including diodes, transistors, thyristors, and other discrete or integrated inorganic semiconductor devices based on materials such as silicon, germanium, gallium arsenide, and similar compounds. It serves as a residual category for inorganic semiconductor inventions that do not fall within the more specialized subclasses H10B (semiconductor devices with at least one potential-jump barrier or surface barrier), H10F (unspecified semiconductor devices), or other dedicated H10 classifications. Typical applications include power electronics, microwave devices, and specialized semiconductor components for which no specific classification exists.
Filing statistics
CPC subclass H10D recorded 324,912 patent applications worldwide between 2013 and 2023. Annual filings grew from 24,303 in 2013 to 30,387 in 2023 (+25%), peaking at 34,149 applications in 2022. The most active applicants in class H10 are SAMSUNG DISPLAY (38,446 applications), TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY (30,922 applications) and SAMSUNG ELECTRONICS COMPANY (30,059 applications).
