Portfolio overview

Hitachi Energy Ltd has been granted 210 US utility patents between 2023 and 2025, placing Hitachi Energy Ltd at rank #1,912 across all assignees tracked by PlainPatent. This portfolio spans 71 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.3 claims per patent with primary concentration in H01F (MAGNETS; INDUCTANCES; TRANSFORMERS; SELECTION OF MATERIALS FOR THEIR MAGNETIC PROPERTIES). As a Foreign Corporation, Hitachi Energy Ltd is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 73.3/100 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 2023 through 2025, with 210 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 Energy Ltd's 16.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 71 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Hitachi Energy Ltd against peers pursuing similar technology classes.
