Portfolio overview

Kobelco Construction Machinery Co., Ltd has been granted 384 US utility patents between 2015 and 2025, placing Kobelco Construction Machinery Co., Ltd at rank #1,107 across all assignees tracked by PlainPatent. This portfolio spans 94 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.7 claims per patent with primary concentration in E02F (DREDGING; SOIL-SHIFTING). As a Foreign Corporation, Kobelco Construction Machinery Co., Ltd is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Kobelco sits between Contemporary Amperex Technology (hong Kong) Limited (387 patents, rank #1,103) and National Oilwell Varco, L.p. (382 patents, rank #1,111) - the closest US assignees by grant volume. The composite Innovation Score of 57.0/100 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 211 grants, compared with 173 in the 2015–2019 window, a +22% 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. Kobelco Construction Machinery Co., Ltd's 6.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 94 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Kobelco Construction Machinery Co., Ltd 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.
