Portfolio overview

Qiaokang Biotech (guangdong) Co., Ltd. has been granted 16 US utility patents between 2021 and 2022, placing Qiaokang Biotech (guangdong) Co., Ltd. at rank #18,022 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.2 claims per patent with primary concentration in A61L (METHODS OR APPARATUS FOR STERILISING MATERIALS OR OBJECTS IN GENERAL; DISINFECTION, STERILISATION OR DEODORISATION OF AIR; CHEMICAL ASPECTS OF BANDAGES, DRESSINGS, ABSORBENT PADS OR SURGICAL ARTICLES;). As a Foreign Corporation, Qiaokang Biotech (guangdong) Co., Ltd. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 32.6/100 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 2022, with 16 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. Qiaokang Biotech (guangdong) Co., Ltd.'s 15.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Qiaokang Biotech (guangdong) Co., Ltd. against peers pursuing similar technology classes.
