Across all tracked assignees
USPTO PatentsView assignee record - 7 granted patents across 7 technology areas, active 2020–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: F24F (AIR-CONDITIONING; AIR-HUMIDIFICATION; VENTILATION; USE OF AIR CURRENTS FOR SCREENING).
The verdict
Hitachi holds 7 US patents across 7 technology areas, rank #35,739 of 50,000 tracked assignees.
Hitachi Global Life Solutions, Inc. has been granted 7 US utility patents between 2020 and 2025, placing Hitachi Global Life Solutions, Inc. at rank #35,739 across all assignees tracked by PlainPatent. This portfolio spans 7 distinct Cooperative Patent Classification (CPC) subclasses, averaging 5.9 claims per patent with primary concentration in F24F (AIR-CONDITIONING; AIR-HUMIDIFICATION; VENTILATION; USE OF AIR CURRENTS FOR SCREENING). As a Foreign Corporation, Hitachi Global Life Solutions, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Hitachi sits between Hinds Instruments, Inc. (7 patents, rank #35,735) and Hobie Cat IP, Llc (7 patents, rank #35,743) - the closest US assignees by grant volume. The composite Innovation Score of 40.0/100 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. Historical data spans 2020 through 2025, with 7 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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 Global Life Solutions, Inc.'s 5.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 7 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Hitachi Global Life Solutions, Inc. against peers pursuing similar technology classes.

How to use this portfolio
Hitachi's 7 grants land it in the top 37% 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.
