Portfolio overview

Wuhan Institute OF Technology has been granted 10 US utility patents between 2020 and 2025, placing Wuhan Institute OF Technology at rank #27,810 across all assignees tracked by PlainPatent. This portfolio spans 21 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.7 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 Institute OF Technology is one of the more focused assignees in the PatentsView dataset. By volume, Wuhan sits between Wilden PUMP AND Engineering Llc (10 patents, rank #27,806) and WWS Acquisition, Llc (10 patents, rank #27,814) - the closest US assignees by grant volume. The composite Innovation Score of 32.4/100 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. Historical data spans 2020 through 2025, with 10 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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 Institute OF Technology's 7.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 21 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Wuhan Institute OF Technology 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.
