Portfolio overview

Qinghai Institute OF SALT Lakes, Chinese Academy OF Sciences has been granted 10 US utility patents between 2021 and 2025, placing Qinghai Institute OF SALT Lakes, Chinese Academy OF Sciences at rank #27,195 across all assignees tracked by PlainPatent. This portfolio spans 16 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.0 claims per patent with primary concentration in C01F (COMPOUNDS OF THE METALS BERYLLIUM, MAGNESIUM, ALUMINIUM, CALCIUM, STRONTIUM, BARIUM, RADIUM, THORIUM, OR OF THE RARE-EARTH METALS). As a Foreign Government, Qinghai Institute OF SALT Lakes, Chinese Academy OF Sciences is one of the more focused assignees in the PatentsView dataset. By volume, Qinghai sits between Pulse Health Llc (10 patents, rank #27,191) and Quantalrf Ag (10 patents, rank #27,199) - the closest US assignees by grant volume. The composite Innovation Score of 48.4/100 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 2021 through 2025, with 10 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. The Foreign Government 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. Qinghai Institute OF SALT Lakes, Chinese Academy OF Sciences's 10.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 16 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Qinghai Institute OF SALT Lakes, Chinese Academy OF Sciences against peers pursuing similar technology classes.
