What this shows Earthclean's Innovation Score is 29.7/100 (32nd 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 Earthclean?

Each dot is one of Earthclean’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). Earthclean’s own 9.7 claims/patent is at or below the 14.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Earthclean's grants concentrate

Earthclean LLC is a focused PatentsView assignee: 8 CPC subclasses with 100% of grants classified under A62D (Chemical Means FOR Extinguishing Fires OR FOR Combating OR Protecting Against Harmful Chemical AGENTS; Chemical Materials FOR USE IN Breathing Apparatus). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2016. By volume, Earthclean sits between E. Dillon & Company and Echostar Broadcasting Corporation.

Earthclean's three-year grant acceleration

Earthclean LLC shows 1 grants in 2022–2024 against only 1 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.
