What this shows Leopold's Innovation Score is 42.5/100 (top 30% 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 Leopold?

Each dot is one of Leopold’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). Leopold’s own 14.6 claims/patent is ABOVE the 13.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Leopold's grants concentrate

Leopold Kostal GmbH & Co. KG is a focused PatentsView assignee: 35 CPC subclasses with 37% of grants classified under H01H (Electric SWITCHES; RELAYS; SELECTORS; Emergency Protective Devices). Peak complete grant year is 2017 (6 grants) versus a trough of 1 in 2020. By volume, Leopold sits between Luziferlamps, S.L. and Loyola University of Chicago.

Leopold's three-year grant acceleration

Leopold Kostal GmbH & Co. KG shows 1 grants in 2022–2024 against only 5 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.
