Portfolio overview

Hitachi RAIL STS S.p.a. has been granted 9 US utility patents between 2022 and 2025, placing Hitachi RAIL STS S.p.a. at rank #28,944 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.3 claims per patent with primary concentration in B61L (GUIDING RAILWAY TRAFFIC; ENSURING THE SAFETY OF RAILWAY TRAFFIC). As a Foreign Corporation, Hitachi RAIL STS S.p.a. is one of the more focused assignees in the PatentsView dataset. By volume, Hitachi sits between Hisep Technology Ltd. (9 patents, rank #28,940) and HONG International Corporation (9 patents, rank #28,948) - the closest US assignees by grant volume. The composite Innovation Score of 48.0/100 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 2022 through 2025, with 9 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 RAIL STS S.p.a.'s 11.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Hitachi RAIL STS S.p.a. against peers pursuing similar technology classes.

How to use this portfolio

Hitachi's 9 grants land it in the top 17% by Innovation Score, but volume alone doesn't tell you where the strength sits.

  • Read that count against the largest US assignees before treating it as dominance - Hitachi ranks #28,944 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in B61L - see who else leads that technology area. B61L leaders
  • Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
