The verdict
Hitachi holds 6 US patents across 3 technology areas, rank #40,637 of 50,000 tracked assignees.
Hitachi Astemo France has been granted 6 US utility patents between 2025 and 2025, placing Hitachi Astemo France at rank #40,637 across all assignees tracked by PlainPatent. This portfolio spans 3 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.2 claims per patent with primary concentration in B60T (VEHICLE BRAKE CONTROL SYSTEMS OR PARTS THEREOF; BRAKE CONTROL SYSTEMS OR PARTS THEREOF, IN GENERAL ; ARRANGEMENT OF BRAKING ELEMENTS ON VEHICLES IN GENERAL; PORTABLE DEVICES FOR PREVENTING UNWANTED MO). As a Foreign Corporation, Hitachi Astemo France is one of the more focused assignees in the PatentsView dataset. By volume, Hitachi sits between Highlight TECH Corp. (6 patents, rank #40,633) and HIYA, Inc. (6 patents, rank #40,641) - the closest US assignees by grant volume. The composite Innovation Score of 21.4/100 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. Historical data spans 2025 through 2025, with 6 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 Astemo France's 14.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while specialization in 3 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Hitachi Astemo France against peers pursuing similar technology classes.

How to use this portfolio
Hitachi's 6 grants land it in the top 92% 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.
