Portfolio overview

Plexbio Co., Ltd. has been granted 10 US utility patents between 2015 and 2024, placing Plexbio Co., Ltd. at rank #27,092 across all assignees tracked by PlainPatent. This portfolio spans 15 distinct Cooperative Patent Classification (CPC) subclasses, averaging 22.2 claims per patent with primary concentration in G01N (INVESTIGATING OR ANALYSING MATERIALS BY DETERMINING THEIR CHEMICAL OR PHYSICAL PROPERTIES). As a Foreign Corporation, Plexbio Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Plexbio sits between Plastic Development Group (10 patents, rank #27,088) and Politechnika Poznanska (10 patents, rank #27,096) - the closest US assignees by grant volume. The composite Innovation Score of 39.3/100 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 5 grants, compared with 5 in the 2015–2019 window, a +0% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Plexbio Co., Ltd.'s 22.2 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 15 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Plexbio Co., Ltd. against peers pursuing similar technology classes.

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
