Portfolio overview

China Special Equipment Inspection & Research Institute has been granted 9 US utility patents between 2020 and 2025, placing China Special Equipment Inspection & Research Institute at rank #28,459 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.2 claims per patent with primary concentration in G01N (INVESTIGATING OR ANALYSING MATERIALS BY DETERMINING THEIR CHEMICAL OR PHYSICAL PROPERTIES). As a Foreign Corporation, China Special Equipment Inspection & Research Institute is one of the more focused assignees in the PatentsView dataset. By volume, China sits between Chef Robotics, Inc. (9 patents, rank #28,455) and Christie Lites Enterprises Canada Inc. (9 patents, rank #28,463) - the closest US assignees by grant volume. The composite Innovation Score of 37.9/100 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. Historical data spans 2020 through 2025, with 9 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. China Special Equipment Inspection & Research Institute's 11.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark China Special Equipment Inspection & Research Institute against peers pursuing similar technology classes.
