Portfolio overview

Hitachi Energy Switzerland Ag has been granted 179 US utility patents between 2021 and 2025, placing Hitachi Energy Switzerland Ag at rank #2,197 across all assignees tracked by PlainPatent. This portfolio spans 82 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.5 claims per patent with primary concentration in G01R (MEASURING ELECTRIC VARIABLES; MEASURING MAGNETIC VARIABLES). As a Foreign Corporation, Hitachi Energy Switzerland Ag is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Hitachi sits between CSMC Technologies FAB2 Co., Ltd. (179 patents, rank #2,193) and Synaptive Medical (barbados) Inc. (179 patents, rank #2,201) - the closest US assignees by grant volume. The composite Innovation Score of 73.5/100 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 179 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 Switzerland Ag's 17.5 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 82 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Hitachi Energy Switzerland Ag 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.
