What this shows Alstom's Innovation Score is 59.1/100 (top 4% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Alstom?

Each dot is one of Alstom’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Alstom’s own 11.0 claims/patent is at or below the 15.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Alstom's grants concentrate

Alstom Holdings is a focused PatentsView assignee: 38 CPC subclasses with 28.6% of grants classified under B61L (Guiding Railway TRAFFIC; Ensuring THE Safety OF Railway Traffic). By volume, Alstom sits between Agricultural Technology Research Institute and AOSense, Inc..

Alstom's three-year grant acceleration

Alstom Holdings shows 10 grants in 2022–2024 against only 0 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
