What this shows Ecocab's Innovation Score is 18.9/100 (5th percentile 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 Ecocab?

Each dot is one of Ecocab’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). Ecocab’s own 4.0 claims/patent is at or below the 16.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Ecocab's grants concentrate

Ecocab Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under F21S (Non-portable Lighting DEVICES; Systems THEREOF; Vehicle Lighting Devices Specially Adapted FOR Vehicle Exteriors). Peak complete grant year is 2019 (3 grants) versus a trough of 1 in 2020. By volume, Ecocab sits between Ebuddy Holding B.V. and Ecotop, LLC.

Ecocab's three-year grant acceleration

Ecocab Co., Ltd. shows 1 grants in 2022–2024 against only 4 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.
