Portfolio overview

Hitachi Industrial Equipment Systems Co., Ltd. has been granted 302 US utility patents between 2015 and 2025, placing Hitachi Industrial Equipment Systems Co., Ltd. at rank #1,393 across all assignees tracked by PlainPatent. This portfolio spans 103 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.8 claims per patent with primary concentration in F04C (ROTARY-PISTON, OR OSCILLATING-PISTON, POSITIVE-DISPLACEMENT MACHINES FOR LIQUIDS ; ROTARY-PISTON, OR OSCILLATING-PISTON, POSITIVE-DISPLACEMENT PUMPS). As a Foreign Corporation, Hitachi Industrial Equipment Systems Co., Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Hitachi sits between Beijing DIDI Infinity Technology AND Development Co., Ltd. (302 patents, rank #1,389) and Skechers U.s.a., Inc. II (302 patents, rank #1,397) - the closest US assignees by grant volume. The composite Innovation Score of 59.8/100 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 198 grants, compared with 104 in the 2015–2019 window, a +90% 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. Hitachi Industrial Equipment Systems Co., Ltd.'s 9.8 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 Hitachi Industrial Equipment Systems Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio

Hitachi's 302 grants land it in the top 4% 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 - Hitachi ranks #1,393 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in F04C - see who else leads that technology area. F04C 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.
