Portfolio overview
MITSUBISHI HEAVY INDUSTRIES ENGINEERING, LTD. has been granted 115 US utility patents between 2018 and 2023, placing MITSUBISHI HEAVY INDUSTRIES ENGINEERING, LTD. at rank #3,260 across all assignees tracked by PlainPatent. This portfolio spans 73 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.3 claims per patent with primary concentration in B01D (SEPARATION). As a Foreign Corporation, MITSUBISHI HEAVY INDUSTRIES ENGINEERING, LTD. is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 48.5/100 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 66 grants, compared with 49 in the 2015–2019 window — a +35% 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. MITSUBISHI HEAVY INDUSTRIES ENGINEERING, LTD.'s 8.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 73 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark MITSUBISHI HEAVY INDUSTRIES ENGINEERING, LTD. against peers pursuing similar technology classes.
