CPC subclass H10F covers INORGANIC SEMICONDUCTOR DEVICES SENSITIVE TO INFRARED RADIATION, LIGHT, ELECTROMAGNETIC RADIATION OF SHORTER WAVELENGTH OR CORPUSCULAR RADIATION. It belongs to CPC class H10 (SEMICONDUCTOR DEVICES; ELECTRIC SOLID-STATE DEVICES NOT OTHERWISE PROVIDED FOR), with 31,010 US utility patents granted since 2015.
How many patents have been filed in H10F?
31,010 US utility patents were granted in CPC subclass H10F between 2015 and 2025, based on USPTO PatentsView data.
Which company holds the most patents in H10F?
Samsung Electronics Co., Ltd. leads H10F with 1,601 patents, making it the most active assignee in this technology area.
How is patent data for H10F collected?
Patent data comes from USPTO PatentsView, a public research dataset maintained by the United States Patent and Trademark Office. It covers all US granted utility patents and assigns CPC codes based on the technology described in each patent.
What is the difference between CPC class and subclass?
A CPC class (e.g., H10) is a broad technology category. Subclasses like H10F provide finer granularity within that category. PlainPatent organizes data at the subclass level (4-character codes) for the most useful view of technology domains.
