Portfolio overview

Nuctech Company Limited has been granted 379 US utility patents between 2015 and 2025, placing Nuctech Company Limited at rank #1,119 across all assignees tracked by PlainPatent. This portfolio spans 101 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.3 claims per patent with primary concentration in G01N (INVESTIGATING OR ANALYSING MATERIALS BY DETERMINING THEIR CHEMICAL OR PHYSICAL PROPERTIES). As a Foreign Corporation, Nuctech Company Limited is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Nuctech sits between Henkel IP & Holding Gmbh (380 patents, rank #1,115) and Chiun Mai Communication Systems, Inc. (377 patents, rank #1,123) - the closest US assignees by grant volume. The composite Innovation Score of 56.2/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Filing cadence tells the strategic story. Between 2020 and 2025 the company received 150 grants, compared with 229 in the 2015–2019 window, a -34% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.

Claim depth and technology breadth together indicate competitive posture. Nuctech Company Limited's 14.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Nuctech Company Limited against peers pursuing similar technology classes.

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.
