What this shows Leitner's Innovation Score is 39.4/100 (top 38% 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 Leitner?

Each dot is one of Leitner’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). Leitner’s own 16.0 claims/patent is ABOVE the 13.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Leitner's grants concentrate

Leitner S.P.A. is a focused PatentsView assignee: 9 CPC subclasses with 100% of grants classified under B61B (Railway SYSTEMS; Equipment Therefor NOT Otherwise Provided FOR). Peak complete grant year is 2022 (6 grants) versus a trough of 1 in 2019. By volume, Leitner sits between Koha Co., Ltd. and Lsil & Co., Inc..

Leitner's three-year grant acceleration

Leitner S.P.A. shows 8 grants in 2022–2024 against only 6 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.
