Portfolio overview

Komatsu Ltd. has been granted 1,303 US utility patents between 2015 and 2025, placing Komatsu Ltd. at rank #331 across all assignees tracked by PlainPatent. This portfolio spans 158 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.9 claims per patent with primary concentration in E02F (DREDGING; SOIL-SHIFTING). As a Foreign Corporation, Komatsu Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Komatsu sits between Aristocrat Technologies Australia Pty Limited (1,316 patents, rank #327) and Yamaha Corporation (1,296 patents, rank #335) - the closest US assignees by grant volume. The composite Innovation Score of 62.9/100 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 589 grants, compared with 714 in the 2015–2019 window, a -18% 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. Komatsu Ltd.'s 10.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Komatsu Ltd. against peers pursuing similar technology classes.

How to use this portfolio

Komatsu's 1,303 grants land it in the top 2% by Innovation Score, but volume alone doesn't tell you where the strength sits.

  • Read that count against the largest US assignees before treating it as dominance - Komatsu ranks #331 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in E02F - see who else leads that technology area. E02F leaders
  • Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
