USPTO PatentsView assignee record - 107 granted patents across 29 technology areas, active 2015–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: H02K (DYNAMO-ELECTRIC MACHINES).
The verdict
Mitsui holds 107 US patents across 29 technology areas, rank #3,454 of 50,000 tracked assignees.
Mitsui High-tec, Inc. has been granted 107 US utility patents between 2015 and 2025, placing Mitsui High-tec, Inc. at rank #3,454 across all assignees tracked by PlainPatent. This portfolio spans 29 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.3 claims per patent with primary concentration in H02K (DYNAMO-ELECTRIC MACHINES). As a Foreign Corporation, Mitsui High-tec, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Mitsui sits between Diebold Nixdorf Incorporated (107 patents, rank #3,450) and Reckitt Benckiser Finish B.v. (107 patents, rank #3,458) - the closest US assignees by grant volume. The composite Innovation Score of 44.2/100 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 38 grants, compared with 69 in the 2015–2019 window, a -45% 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. Mitsui High-tec, Inc.'s 9.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 29 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Mitsui High-tec, Inc. against peers pursuing similar technology classes.

How to use this portfolio
Mitsui's 107 grants land it in the top 26% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
