Frequently Asked Questions

What is CPC class H02S?

CPC subclass H02S covers GENERATION OF ELECTRIC POWER BY CONVERSION OF INFRARED RADIATION, VISIBLE LIGHT OR ULTRAVIOLET LIGHT, e.g. USING PHOTOVOLTAIC [PV] MODULES. It belongs to CPC class H02 (GENERATION; CONVERSION OR DISTRIBUTION OF ELECTRIC POWER), with 6,483 US utility patents granted since 2015.

How many patents have been filed in H02S?

6,483 US utility patents were granted in CPC subclass H02S between 2015 and 2025, based on USPTO PatentsView data.

Which company holds the most patents in H02S?

Sunpower Corporation leads H02S with 212 patents, making it the most active assignee in this technology area.

How is patent data for H02S 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., H02) is a broad technology category. Subclasses like H02S provide finer granularity within that category. PlainPatent organizes data at the subclass level (4-character codes) for the most useful view of technology domains.
