Portfolio overview
Hangzhou Singclean Medical Products Co., Ltd has been granted 10 US utility patents between 2018 and 2024, placing Hangzhou Singclean Medical Products Co., Ltd at rank #26,472 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.8 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, Hangzhou Singclean Medical Products Co., Ltd is one of the more focused assignees in the PatentsView dataset. By volume, Hangzhou sits between Hamburger's Specialty Vehicles, Inc. (10 patents, rank #26,468) and Harken, Incorporated (10 patents, rank #26,476) - the closest US assignees by grant volume. The composite Innovation Score of 34.6/100 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. Between 2020 and 2025 the company received 9 grants, compared with 1 in the 2015–2019 window, a +800% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Hangzhou Singclean Medical Products Co., Ltd's 8.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Hangzhou Singclean Medical Products Co., Ltd against peers pursuing similar technology classes.
