Portfolio overview

ALSTOM Holdings has been granted 21 US utility patents between 2024 and 2025, placing ALSTOM Holdings at rank #13,838 across all assignees tracked by PlainPatent. This portfolio spans 38 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.0 claims per patent with primary concentration in B61L (GUIDING RAILWAY TRAFFIC; ENSURING THE SAFETY OF RAILWAY TRAFFIC). As a Foreign Corporation, ALSTOM Holdings is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 59.1/100 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 2024 through 2025, with 21 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. ALSTOM Holdings's 11.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 38 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark ALSTOM Holdings against peers pursuing similar technology classes.
