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 11.3 claims/patent is ABOVE the 8.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
How Alstom's grant cadence moved
Between 2020–2024, Alstom Transport Technologies received 122 grants versus 110 in 2015–2019 (+11% equal-window velocity, above median growth). Across complete PatentsView years, output peaked in 2020 at 47 grants and bottomed in 2015 at 6. Lead class B61L accounts for 36.5% of the portfolio across 113 subclasses. Volume neighbours: Williams-Sonoma, Inc. (#1,738) and Magna International Inc. (#1,746).
Alstom's three-year grant acceleration
From 2019–2021 to 2022–2024, Alstom Transport Technologies moved from 134 to 34 grants (0.25x the prior three-year total, a multiple, not a CAGR). Among 3,296 tracked assignees with ≥100 grants and ≥20 prior-period grants, that multiple ranks #3,039. See the growth leaderboard.
