Portfolio overview

Nanjing Forestry University has been granted 28 US utility patents between 2017 and 2025, placing Nanjing Forestry University at rank #11,012 across all assignees tracked by PlainPatent. This portfolio spans 46 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.0 claims per patent with primary concentration in C07F (ACYCLIC, CARBOCYCLIC OR HETEROCYCLIC COMPOUNDS CONTAINING ELEMENTS OTHER THAN CARBON, HYDROGEN, HALOGEN, OXYGEN, NITROGEN, SULFUR, SELENIUM OR TELLURIUM). As a Foreign Corporation, Nanjing Forestry University is one of the more focused assignees in the PatentsView dataset. By volume, Nanjing sits between Metal Raptor Inc. (28 patents, rank #11,008) and Nexter Munitions (28 patents, rank #11,016) - the closest US assignees by grant volume. The composite Innovation Score of 48.7/100 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 25 grants, compared with 3 in the 2015–2019 window, a +733% 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. Nanjing Forestry University's 7.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 46 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Nanjing Forestry 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.
