Portfolio overview
Shanghai Chuangshi Medical Technology (group) Co., Ltd. has been granted 14 US utility patents between 2022 and 2024, placing Shanghai Chuangshi Medical Technology (group) Co., Ltd. at rank #20,434 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 1.9 claims per patent with primary concentration in A61F (FILTERS IMPLANTABLE INTO BLOOD VESSELS; PROSTHESES; DEVICES PROVIDING PATENCY TO, OR PREVENTING COLLAPSING OF, TUBULAR STRUCTURES OF THE BODY, e.g. STENTS; ORTHOPAEDIC, NURSING OR CONTRACEPTIVE DEVICE). As a Foreign Corporation, Shanghai Chuangshi Medical Technology (group) Co., Ltd. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 38.4/100 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 2022 through 2024, with 14 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. Shanghai Chuangshi Medical Technology (group) Co., Ltd.'s 1.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 5 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Shanghai Chuangshi Medical Technology (group) Co., Ltd. against peers pursuing similar technology classes.
