Portfolio overview

Mitsubishi Heavy Industries Machine TOOL Co., Ltd. has been granted 53 US utility patents between 2016 and 2025, placing Mitsubishi Heavy Industries Machine TOOL Co., Ltd. at rank #6,359 across all assignees tracked by PlainPatent. This portfolio spans 31 distinct Cooperative Patent Classification (CPC) subclasses, averaging 5.5 claims per patent with primary concentration in B23F (MAKING GEARS OR TOOTHED RACKS). As a Foreign Corporation, Mitsubishi Heavy Industries Machine TOOL Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Mitsubishi sits between LMK Technologies, Llc (53 patents, rank #6,355) and Newmax Technology Co., Ltd. (53 patents, rank #6,363) - the closest US assignees by grant volume. The composite Innovation Score of 37.1/100 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 9 grants, compared with 44 in the 2015–2019 window, a -80% 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 Machine TOOL Co., Ltd.'s 5.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 31 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Mitsubishi Heavy Industries Machine TOOL Co., Ltd. against peers pursuing similar technology classes.

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
