Portfolio overview

Mitsubishi Heavy Industries Engine & Turbocharger, Ltd. has been granted 278 US utility patents between 2018 and 2025, placing Mitsubishi Heavy Industries Engine & Turbocharger, Ltd. at rank #1,497 across all assignees tracked by PlainPatent. This portfolio spans 63 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.6 claims per patent with primary concentration in F02B (INTERNAL-COMBUSTION PISTON ENGINES; COMBUSTION ENGINES IN GENERAL). As a Foreign Corporation, Mitsubishi Heavy Industries Engine & Turbocharger, Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Mitsubishi sits between Amkor Technology Singapore Holding Pte. Ltd. (278 patents, rank #1,493) and Conti Temic Microelectronic Gmbh (277 patents, rank #1,501) - the closest US assignees by grant volume. The composite Innovation Score of 56.3/100 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 236 grants, compared with 42 in the 2015–2019 window, a +462% 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. Mitsubishi Heavy Industries Engine & Turbocharger, Ltd.'s 9.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 63 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Mitsubishi Heavy Industries Engine & Turbocharger, Ltd. against peers pursuing similar technology classes.
