What this shows Earth's Innovation Score is 26.4/100 (20th 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 Earth?

Each dot is one of Earth’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). Earth’s own 9.8 claims/patent is at or below the 9.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Earth's grants concentrate

Earth Corporation is a focused PatentsView assignee: 4 CPC subclasses with 33.3% of grants classified under C08J (WORKING-UP; General Processes OF COMPOUNDING; After-treatment NOT Covered BY Subclasses C08b, C08c, C08f, C08g or C08h). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2016. By volume, Earth sits between Exergy S.P.A. and Eckold GmbH & Co. KG.

Earth's three-year grant acceleration

Earth Corporation shows 2 grants in 2022–2024 against only 2 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.
