Portfolio overview

Mitsubishi Heavy Industries Environmental & Chemical Engineering Co., Ltd. has been granted 17 US utility patents between 2017 and 2023, placing Mitsubishi Heavy Industries Environmental & Chemical Engineering Co., Ltd. at rank #16,983 across all assignees tracked by PlainPatent. This portfolio spans 23 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.2 claims per patent with primary concentration in F23G (CREMATION FURNACES; CONSUMING WASTE PRODUCTS BY COMBUSTION). As a Foreign Corporation, Mitsubishi Heavy Industries Environmental & Chemical Engineering Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Mitsubishi sits between Metrotech Corporation (17 patents, rank #16,979) and MOBA Group B.v. (17 patents, rank #16,987) - the closest US assignees by grant volume. The composite Innovation Score of 32.3/100 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 5 grants, compared with 12 in the 2015–2019 window, a -58% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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 Environmental & Chemical Engineering Co., Ltd.'s 6.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 23 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Mitsubishi Heavy Industries Environmental & Chemical Engineering Co., Ltd. against peers pursuing similar technology classes.
