USPTO PatentsView assignee record - 233 granted patents across 113 technology areas, active 2015–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: B61L (GUIDING RAILWAY TRAFFIC; ENSURING THE SAFETY OF RAILWAY TRAFFIC).
The verdict
Alstom holds 233 US patents across 113 technology areas, rank #1,742 of 50,000 tracked assignees.
Alstom Transport Technologies has been granted 233 US utility patents between 2015 and 2025, placing Alstom Transport Technologies at rank #1,742 across all assignees tracked by PlainPatent. This portfolio spans 113 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, Alstom Transport Technologies is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Alstom sits between Williams-sonoma, Inc. (235 patents, rank #1,738) and Magna International Inc. (233 patents, rank #1,746) - the closest US assignees by grant volume. The composite Innovation Score of 52.4/100 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. Between 2020 and 2025 the company received 123 grants, compared with 110 in the 2015–2019 window, a +12% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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 Transport Technologies's 11.3 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 Alstom Transport Technologies against peers pursuing similar technology classes.

How to use this portfolio
Alstom's 233 grants land it in the top 10% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
