Portfolio overview

Nanjing TECH University has been granted 90 US utility patents between 2015 and 2025, placing Nanjing TECH University at rank #4,017 across all assignees tracked by PlainPatent. This portfolio spans 92 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.4 claims per patent with primary concentration in B01D (SEPARATION). As a Foreign Government, Nanjing TECH University is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Nanjing sits between Medacta International Sa (90 patents, rank #4,013) and Quanta Associates, L.p. (90 patents, rank #4,021) - the closest US assignees by grant volume. The composite Innovation Score of 58.7/100 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 63 grants, compared with 27 in the 2015–2019 window, a +133% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The Foreign Government 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. Nanjing TECH University's 9.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 92 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Nanjing TECH University 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.
