Portfolio overview

Wuhan University OF Technology has been granted 77 US utility patents between 2015 and 2025, placing Wuhan University OF Technology at rank #4,595 across all assignees tracked by PlainPatent. This portfolio spans 81 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.8 claims per patent with primary concentration in C04B (LIME, MAGNESIA; SLAG; CEMENTS; COMPOSITIONS THEREOF, e.g. MORTARS, CONCRETE OR LIKE BUILDING MATERIALS; ARTIFICIAL STONE ; CERAMICS ; REFRACTORIES; TREATMENT OF NATURAL STONE). As a Foreign Corporation, Wuhan University OF Technology is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Wuhan sits between Umm-al-qura University (77 patents, rank #4,591) and Arcadyan Technology Corporation (76 patents, rank #4,599) - the closest US assignees by grant volume. The composite Innovation Score of 64.1/100 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 70 grants, compared with 7 in the 2015–2019 window, a +900% 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. Wuhan University OF Technology's 6.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 81 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Wuhan University OF Technology against peers pursuing similar technology classes.
