Portfolio overview

HANGZHOU BIOTEST BIOTECH CO., LTD. has been granted 30 US utility patents between 2020 and 2025, placing HANGZHOU BIOTEST BIOTECH CO., LTD. at rank #10,340 across all assignees tracked by PlainPatent. This portfolio spans 3 distinct Cooperative Patent Classification (CPC) subclasses, averaging 5.6 claims per patent with primary concentration in B01L (CHEMICAL OR PHYSICAL LABORATORY APPARATUS FOR GENERAL USE). As a Foreign Corporation, HANGZHOU BIOTEST BIOTECH CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 32.2/100 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 2020 through 2025, with 30 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. HANGZHOU BIOTEST BIOTECH CO., LTD.'s 5.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 3 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark HANGZHOU BIOTEST BIOTECH CO., LTD. against peers pursuing similar technology classes.

How to use this portfolio

Hangzhou's 30 grants land it in the top 60% by Innovation Score, but volume alone doesn't tell you where the strength sits.
