It belongs to CPC class G01 (MEASURING; TESTING), with 14,112 US utility patents granted since 2015.
How many patents have been filed in G01D?
14,112 US utility patents were granted in CPC subclass G01D between 2015 and 2025, based on USPTO PatentsView data.
Which company holds the most patents in G01D?
Infineon Technologies Ag leads G01D with 328 patents, making it the most active assignee in this technology area.
How is patent data for G01D 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., G01) is a broad technology category. Subclasses like G01D provide finer granularity within that category. PlainPatent organizes data at the subclass level (4-character codes) for the most useful view of technology domains.
