Portfolio overview

Hitachi High-tech Corporation has been granted 1,071 US utility patents between 2020 and 2025, placing Hitachi High-tech Corporation at rank #422 across all assignees tracked by PlainPatent. This portfolio spans 125 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.3 claims per patent with primary concentration in G01N (INVESTIGATING OR ANALYSING MATERIALS BY DETERMINING THEIR CHEMICAL OR PHYSICAL PROPERTIES). As a Foreign Corporation, Hitachi High-tech Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Hitachi sits between Regents Of The University Of Minnesota (1,081 patents, rank #418) and Lawrence Livermore National Security, Llc (1,064 patents, rank #426) - the closest US assignees by grant volume. The composite Innovation Score of 67.0/100 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 1,071 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 High-tech Corporation's 10.3 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 High-tech Corporation 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.
