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 #18,026 of 50,000 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. By volume, Qiaokang sits between Professional Disposables International Inc. (16 patents, rank #18,018) and Qinterra Technologies AS (16 patents, rank #18,026) - the closest US assignees by grant volume. The composite Innovation Score of 32.6/100 blends portfolio volume, grant velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Grant cadence records the difference between two grant-year windows. Historical data spans 2021 through 2022, with 16 total grants over that period. Grant timing can lag the related application by years, so this comparison does not establish current R&D spending, strategic intent, or a company’s application activity. The Foreign Corporation classification provides context for the assignee record, not a conclusion about its business strategy.

Claim depth and technology breadth describe this aggregate record. Qiaokang Biotech (guangdong) Co., Ltd.'s 15.2 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 14 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
