Portfolio overview

Mitsubishi Hitachi Power Systems Environmental Solutions, Ltd. has been granted 17 US utility patents between 2016 and 2020, placing Mitsubishi Hitachi Power Systems Environmental Solutions, Ltd. at rank #16,984 across all assignees tracked by PlainPatent. This portfolio spans 22 distinct Cooperative Patent Classification (CPC) subclasses, averaging 4.5 claims per patent with primary concentration in Y02E (REDUCTION OF GREENHOUSE GAS [GHG] EMISSIONS, RELATED TO ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION). As a Foreign Corporation, Mitsubishi Hitachi Power Systems Environmental Solutions, Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Mitsubishi sits between Metso FLOW Control OY (17 patents, rank #16,980) and Modern Meadow, Inc. (17 patents, rank #16,988) - the closest US assignees by grant volume. The composite Innovation Score of 29.3/100 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 2 grants, compared with 15 in the 2015–2019 window, a -87% 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 Hitachi Power Systems Environmental Solutions, Ltd.'s 4.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 22 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Mitsubishi Hitachi Power Systems Environmental Solutions, Ltd. against peers pursuing similar technology classes.

How to use this portfolio

Mitsubishi's 17 grants land it in the top 70% 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 - Mitsubishi ranks #16,984 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in Y02E - see who else leads that technology area. Y02E 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.
