Overall rank by patents
#10,406
of 50,000 tracked assignees
USPTO PatentsView assignee record - 30 granted patents across 25 technology areas, recorded in grant years 2015–2025. Grant-trend analysis is cross-referenced to USPTO Patent Public Search; it does not measure application filings, current R&D, or legal strength. Primary class: G01J (MEASUREMENT OF INTENSITY, VELOCITY, SPECTRAL CONTENT, POLARISATION, PHASE OR PULSE CHARACTERISTICS OF INFRARED, VISIBLE OR ULTRAVIOLET LIGHT; COLORIMETRY; RADIATION PYROMETRY).
The verdict
According to USPTO PatentsView, National ranks #10,406 of 50,000 tracked US assignees by granted-patent volume, with 30 patents across 25 technology areas.
National Institute OF Metrology, China has been granted 30 US utility patents between 2015 and 2025, placing National Institute OF Metrology, China at #10,406 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 25 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.5 claims per patent with primary concentration in G01J (MEASUREMENT OF INTENSITY, VELOCITY, SPECTRAL CONTENT, POLARISATION, PHASE OR PULSE CHARACTERISTICS OF INFRARED, VISIBLE OR ULTRAVIOLET LIGHT; COLORIMETRY; RADIATION PYROMETRY). As a Foreign Corporation, National Institute OF Metrology, China is one of the more focused assignees in the PatentsView dataset. By volume, National sits between Magnolia Broadband Inc. (30 patents, rank #10,402) and Neumodx Molecular, Inc. (30 patents, rank #10,410) - the closest US assignees by grant volume. The composite Innovation Score of 55.3/100 blends portfolio volume, grant velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.
Grant cadence records the difference between two grant-year windows. Between 2020 and 2024 the company received 15 grants, compared with 10 in the 2015–2019 window, a +50% shift in five-year grant velocity. Both windows cover five complete grant years; the latest PatentsView year is a partial release and is excluded from this comparison, though it still appears in the yearly table and chart below. Grant timing can lag the related application by years, so this comparison does not establish current R&D spending, strategic intent, or a company’s application activity. The Foreign Corporation classification provides context for the assignee record, not a conclusion about its business strategy.
Claim depth and technology breadth describe this aggregate record. National Institute OF Metrology, China's 9.5 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 25 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.

How to use this portfolio
National's 30 grants land it in the top 7% by Innovation Score, but volume alone doesn't tell you where the strength sits.
Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
