USPTO PatentsView assignee record - 10 granted patents across 6 technology areas, active 2018–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: G01J (MEASUREMENT OF INTENSITY, VELOCITY, SPECTRAL CONTENT, POLARISATION, PHASE OR PULSE CHARACTERISTICS OF INFRARED, VISIBLE OR ULTRAVIOLET LIGHT; COLORIMETRY; RADIATION PYROMETRY).
The verdict
Hitachi holds 10 US patents across 6 technology areas, rank #26,445 of 50,000 tracked assignees.
Hitachi High-tech Analytical Science Gmbh has been granted 10 US utility patents between 2018 and 2025, placing Hitachi High-tech Analytical Science Gmbh at rank #26,445 across all assignees tracked by PlainPatent. This portfolio spans 6 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.7 claims per patent with primary concentration in G01J (MEASUREMENT OF INTENSITY, VELOCITY, SPECTRAL CONTENT, POLARISATION, PHASE OR PULSE CHARACTERISTICS OF INFRARED, VISIBLE OR ULTRAVIOLET LIGHT; COLORIMETRY; RADIATION PYROMETRY). As a Foreign Corporation, Hitachi High-tech Analytical Science Gmbh is one of the more focused assignees in the PatentsView dataset. By volume, Hitachi sits between HIL Applied Medical, Ltd. (10 patents, rank #26,441) and Hokko Chemical Industry Co., Ltd. (10 patents, rank #26,449) - the closest US assignees by grant volume. The composite Innovation Score of 32.4/100 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 8 grants, compared with 2 in the 2015–2019 window, a +300% 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 High-tech Analytical Science Gmbh's 14.7 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 6 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Hitachi High-tech Analytical Science Gmbh against peers pursuing similar technology classes.

How to use this portfolio
Hitachi's 10 grants land it in the top 59% 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.
