Portfolio overview

Hitachi Astemo, Ltd. has been granted 1,145 US utility patents between 2021 and 2025, placing Hitachi Astemo, Ltd. at rank #385 across all assignees tracked by PlainPatent. This portfolio spans 143 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.9 claims per patent with primary concentration in B60W (CONJOINT CONTROL OF VEHICLE SUB-UNITS OF DIFFERENT TYPE OR DIFFERENT FUNCTION; CONTROL SYSTEMS SPECIALLY ADAPTED FOR HYBRID VEHICLES; ROAD VEHICLE DRIVE CONTROL SYSTEMS FOR PURPOSES NOT RELATED TO THE). As a Foreign Corporation, Hitachi Astemo, Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Hitachi sits between The United States Of America As Represented By The Secretary Of The Army (1,151 patents, rank #381) and Aisin Seiki Kabushiki Kaisha (1,137 patents, rank #389) - the closest US assignees by grant volume. The composite Innovation Score of 75.3/100 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. Historical data spans 2021 through 2025, with 1,145 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, Ltd.'s 9.9 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 Astemo, Ltd. against peers pursuing similar technology classes.

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.
