What this shows Earth's Innovation Score is 35.7/100 (top 49% 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 20.2 claims/patent is ABOVE the 14.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Earth's grants concentrate

Earth Science Laboratories, Inc. is a focused PatentsView assignee: 8 CPC subclasses with 90.9% of grants classified under C02F (Treatment OF Water, Waste Water, Sewage, OR Sludge). Peak complete grant year is 2018 (4 grants) versus a trough of 1 in 2019. By volume, Earth sits between Extron Company and Ecolean AB.

Earth's three-year grant acceleration

Earth Science Laboratories, Inc. shows 3 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.
