Portfolio overview

DOOSAN MACHINE TOOLS CO., LTD. has been granted 36 US utility patents between 2016 and 2022, placing DOOSAN MACHINE TOOLS CO., LTD. at rank #8,778 across all assignees tracked by PlainPatent. This portfolio spans 12 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.1 claims per patent with primary concentration in B23Q (DETAILS, COMPONENTS, OR ACCESSORIES FOR MACHINE TOOLS, e.g. ARRANGEMENTS FOR COPYING OR CONTROLLING ; MACHINE TOOLS IN GENERAL CHARACTERISED BY THE CONSTRUCTION OF PARTICULAR DETAILS OR COMPONENTS; CO). As a Foreign Corporation, DOOSAN MACHINE TOOLS CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 31.0/100 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 19 grants, compared with 17 in the 2015–2019 window — a +12% 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. DOOSAN MACHINE TOOLS CO., LTD.'s 6.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 12 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark DOOSAN MACHINE TOOLS CO., LTD. against peers pursuing similar technology classes.
