Portfolio overview

Sumitomo Construction Machinery Co., Ltd. has been granted 174 US utility patents between 2015 and 2025, placing Sumitomo Construction Machinery Co., Ltd. at rank #2,258 across all assignees tracked by PlainPatent. This portfolio spans 53 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.6 claims per patent with primary concentration in E02F (DREDGING; SOIL-SHIFTING). As a Foreign Corporation, Sumitomo Construction Machinery Co., Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Sumitomo sits between NAN YA Plastics Corporation (174 patents, rank #2,254) and Beckhoff Automation Gmbh (173 patents, rank #2,262) - the closest US assignees by grant volume. The composite Innovation Score of 61.2/100 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 120 grants, compared with 54 in the 2015–2019 window, a +122% 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. Sumitomo Construction Machinery Co., Ltd.'s 12.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 53 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Sumitomo Construction Machinery Co., Ltd. against peers pursuing similar technology classes.
