Portfolio overview
Suzhou Pengxu Pharmatech Co. Ltd. has been granted 11 US utility patents between 2017 and 2025, placing Suzhou Pengxu Pharmatech Co. Ltd. at rank #25,208 across all assignees tracked by PlainPatent. This portfolio spans 8 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.1 claims per patent with primary concentration in C07D (HETEROCYCLIC COMPOUNDS). As a Foreign Corporation, Suzhou Pengxu Pharmatech Co. Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Suzhou sits between SUSS Microtec Photomask Equipment Gmbh & Co (11 patents, rank #25,204) and Synerscope B.v. (11 patents, rank #25,212) - the closest US assignees by grant volume. The composite Innovation Score of 34.1/100 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 6 grants, compared with 5 in the 2015–2019 window, a +20% 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. Suzhou Pengxu Pharmatech Co. Ltd.'s 11.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 8 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Suzhou Pengxu Pharmatech Co. Ltd. against peers pursuing similar technology classes.
